It is written lớn aid you in the design and build of your own printer. I have included config files và macros for Reprap firmware & STEP files for the various printer parts to allow you khổng lồ draw inspiration from và be able lớn build my machine.

This Instructables takes a very linear approach lớn the design process which is one of the caveats of writing an article formed of steps. In reality the kiến thiết process is much more cyclic và involves no kết thúc of iteration và repetition of the steps below. What you see here is the thiết kế that I settled on and ended up building at the end of an almost two-year long project và is iteration 52 of the original design (and will likely not be its final form). My advice to lớn the budding printer designer is lớn not take lightly the challenge you are taking on; it will take many hours và many failed ideas but push on!

As with any project, safety should come first. This project involves working with several tools, mains electricity, và heaters that reach over 250 ºC. When working with mains electricity ensure that the workpiece is isolated from the supply và that your breaker has an RCD. Ensure that cables are well connected và do not expose any conductor. Avoid handling heaters while under power và remember that heaters will remain hot long after the machine has been shut down. Take care when working with tools & always use the right tool for the job. It is your responsibility khổng lồ make sure that you are working safely và understand the dangers present. Follow this Instructable at your own risk.


Step 1: Printer Specification


Speed, Quality, và Cost - Pick two.

It"s a famous saying (cliché?) but it holds a lot of truth. You can’t set out khổng lồ achieve all three and so some sacrifices must be made along the way. Setting a clear specification for what you want và where you are willing khổng lồ make sacrifices is essential lớn keeping you on track và working towards consistent goals. Without a specification you run the risk of entering a never-ending thiết kế cycle or suffering from moving goal posts.

Quality và Cost

For me chất lượng comes first. This printer build is focused on delivering high unique 3D prints that are dimensionally accurate and reliable at the expense of print speed, and cost.

Another key requirement was reliability. I wanted khổng lồ build a machine that I could confidently rely on to create in spec parts, that look great, và wouldn’t burn my house down. That means that this machine wasn’t designed to lớn cut costs wherever possible và so some of the parts could be sourced cheaper but at a lower quality or with a lower factor-of-safety.

Build Volume

Most parts that I print are engineering prototypes and typically fall into a small build volume. Having owned both a 300 mm^3 and 220 mm^3 printer for several years and never having printed anything larger than 100 mm^3 it seemed obvious khổng lồ build a smaller printer & take advantage of some of the benefits this can deliver such as shorter belt runs, a more rigid frame, và most importantly a smaller footprint! For that reason, the printer will be made around a 200 x 200 x 200 milimet build volume.

Printer Size

Desk real estate is a hugely valuable commodity in offices & workshops. With that in mind I want to minimise the footprint of the printer. A maximum kích cỡ requirement is 450 x 450 mm. I also wanted the electronics lớn be attached lớn the printer & safely contained to lớn prevent damage lớn them and to keep the machine tidy.


Step 2: Chassis


*

The chassis is the fundamental structure that holds the printer together, mounts all of the sub systems, & gives it the much-needed rigidity that is intrinsically tied into good chất lượng prints.

Aluminium Extrusion

I wanted to create something easy to lớn build with relatively limited tools và equipment but without incurring high sub-contract costs for contract machining / fabrication. The obvious answer khổng lồ this was aluminium extrusion profiles which are popular among the maker and engineering communities thanks lớn their ‘lego-like" quick and easy assembly with minimal processing cost. Another huge benefit of the aluminium extrusion system is the high number of sub-contractors willing khổng lồ cut it to lớn length for a competitive price.

Aluminium extrusion can be anodised in a range of colours but clear (silver) & black are the most common & therefore cheapest. I initially ordered clear extrusions but due to a small mix up ended up with black extrusions… queue quick colour scheme overhaul. You can purchase plastic pieces that fit into the gaps of the extrusion which tidies up the look & allow you to lớn use the extrusion channels for running cables.

Despite the small target build volume of the printer I opted lớn use 3030 extrusions as they offer a significant upgrade in rigidity (especially at the joints) và also make the design scalable up to lớn a much larger size if that is ever required.

Blind Joints

Aluminium extrusion can be connected in a huge range of ways including (but not limited to) various angle brackets, hinges, pivots, extenders, & blind joints. Blind joints involve tapping (cutting a thread into) the kết thúc of the extrusion and using a button head bolt to lớn clamp the two extrusions together at right angles.

I chose to lớn use the blind joints as they reduce the part count (reducing cost), reduce the number of tolerances lớn control (meaning you can easily get a square frame with a strong metal-to-metal joint), & allow you lớn easily connect frame members at almost any point. This type of joint does require a simple cross hole lớn be drilled lớn allow Allen key access for tightening the button head bolts but fortunately many sub-contractors will also drill these cross holes for a small fee whilst cutting the extrusions to lớn length. By using blind joints throughout the entire frame there is no plastic that can introduce flex in the frame creating an extremely rigid chassis.

Basic Cube

I stuck lớn a basic cube construction for simplicity & for how it lends itself lớn the Core
XY belt paths. I lowered the front cross thành viên so that visibility of the print head (and the print in progress) is not obstructed. I avoided removing it entirely as it provides a significant amount of structural rigidity lớn the frame.

I added an extra space at the bottom of the frame used khổng lồ store the electronics for the printer. This helps to lớn keep everything neat and tidy và attached to the machine và by placing electronics on the bottom it prevents me from having to lớn increase the footprint of the printer just for the electronics. Once installed the electronics will be covered with tia laze cut panels lớn hide the mess of wiring!


Step 3: Motion Platform


*
*
*
*

The XY motion platform is responsible for the XY movements of the printer và so is fundamental to lớn the printer’s performance. There are several different popular motion schemes each offering pros and cons. The main kinematics are Cartesian, Delta, và Core
XY each with their own subtle variants.

Core XY

Core
XY is a 2-axis kinematic system that features a coupled X & Y axis. The main focus of the Core
XY design is khổng lồ reduce the weight that the print head has to carry by placing the motors on the frame instead of on the X and Y axis. This reduced weight allows the head to lớn accelerate much harder whilst still accessing a square bed. The required belt paths are however reasonably long meaning belt stretch becomes an issue at larger build volume sizes (>350 mm sqaure), but this won’t be an issue at our target build size. Many pulleys are required và careful alignment and tensing lớn prevent gantry racking or irregular movement is essential. The Core
XY belt path also requires a small margin around the bed lớn house the various idlers, pulley và motors. Since Core
XY only handles the XY axis a third Cartesian axis for the Z axis is required.

A full explanation of the Core
XY kinematics can be found on the Core
XY website.

Linear Rails

The X and Y axis require a linear sliding element for smooth motion. Linear bearings running on round rods are the most common thiết đặt for 3d printers, but the rods are poorly supported along their length thanks to lớn only being mounted at either end and offer poor rigidity. Linear rails lượt thích those available from Misumi, Hi
Win, etc offer a significantly more rigid joint thanks khổng lồ being mounted along its entire length and also don’t roll like linear bearings and so I chose lớn use some reasonably priced linear rails from Aliexpress. While the Chinese manufactured rails are certainly lower quality, they are still more than suitable for a 3d printer and come at a significant (10x) cost reduction over name brand offerings.

X & Y Axis

I opted khổng lồ mount my linear rails to the underside of the extrusion as it reduces the amount of XY space required, ensures an even loading on the rails, và helps protect them from dust ingress which will extend the rail lifetime.

A piece of 2020 extrusion is used to tư vấn the X-axis rail. This provides a lightweight but rigid tư vấn with a wide range of mounting options. The X axis is then mounted to the Y axis with two printed pieces that also house the required pulleys khổng lồ align the belts. This is the only structural plastic part in the entire motion platform.

AB Drives

In place of the typical cartesian X and Y motors a Core
XY printer has two motors named A & B which are often connected directly into the Core
XY belts. I decided khổng lồ connect the motors to lớn the Core
XY belts with a belt loop so that the motors could be placed in a more convenient location. The belt loop also has the advantage of allowing a gear ratio to lớn be introduced between the motor and the Core
XY belts by varying the pulleys used. A ratio between 2.5:1 & 1:2.5 can be achieved. I initially chose a ratio of 1:0.8 to lớn slightly reduce speed và increase resolution but this can easily be changed at any time to fine tune to lớn the type of printing you want lớn achieve.

Belt Path

For this machine I opted lớn use a GT2 belts which are ubiquitous in 3 chiều printers thanks lớn their low cost, easy sourcing, and good control. Implementing the Core
XY belting successfully requires careful placement of the pulleys to lớn ensure parallelism of the belt. Any errors in belt alignment will result in poor motion platform performance.

The original Core
XY belt path requires the two belts khổng lồ cross to cancel a twisting force but this can cause some odd pulley alignment & uneven wear on the belts. Since the linear rails are capable of handling the twisting forces, I instead opted for a stacked belt style that makes the belt routing much simpler. Since the motors are not being mounted to lớn the Core
XY belt path I was able to run the belts along the inside of the frame, keeping them compact & out of the way. Another pulley was added lớn the front idlers of the machine pinching the return path closer khổng lồ the frame of the printer increasing the X-axis length without having to lớn make the machine bigger. Belt tensioners were added khổng lồ the front of the machine for easy tensioning of the belts.

Tool Head

The tool head holds the hotend, Z probe & part cooling fans together. I wanted the printer to lớn be adaptable and mở cửa to other hotend và cooling options và so wanted to use a quick-change head. Instead of reinventing the wheel here & introducing another competing standard I opted to use the Voron quick change tool head since it offers quick tool changes (2 screws) và already has heads available for the E3D V6 (in both regular & volcano configuration), Slice Mosquito, and the TL Dragon. The mounting plate only required minor edits khổng lồ suit my belt paths & to mount to lớn a PINDA probe.


Step 4: Z Axis


*
*
*

The Z axis is responsible for the fine positioning of the bed to create the layers of the 3 chiều print. One of the key concerns here is the infamous “Z Wobble” effect where the axis wobbles from side lớn side as it travels creating significant và repeated rippling patterns on the surface of prints. Key to lớn overcoming this is careful design of the Z axis so that it is not over constrained but is properly supported.

A lot of popular printers have a cantilevered bed where the bed is only supported và driven on one side. While this makes the mounting, assembly, and alignment much simpler it also doesn"t fully tư vấn the bed & so you get inaccurate movement the further away from the tư vấn column thanks to the bed drooping. Other machines support the bed at all four corners which ends up over-constraining it & requiring challenging rail alignment.

I opted for a hybrid cantilevered thiết kế which supports the bed at the back lớn control X, Y, và pitching movements but then uses three lead screws equally spaced around the bed lớn control Z, Yaw, & roll movement.

Using three screws makes sense since the three points at which it holds the bed perfectly defines the plane. Implementing independent control of the three screws would allow the printer to cấp độ itself but would require 3 independent drivers and motors adding significant cost. For the initial build I instead opted to lớn save the cost và use a single motor & driver and connected all of the lead screws together with a single belt loop. At a later date the machine could be easily updated to include independent control.

Aligning the lead screws khổng lồ the bed is also essential as otherwise they can apply a force to lớn the bed causing Z wobble. Each screw is mounted lớn a flexible coupling which will allow for a small amount of angular misalignment making assembly significantly more forgiving. Each screw is mounted through the flexible coupling khổng lồ a shaft that holds a GT2 pulley và is held in place by two KFL08 bearing blocks mounted lớn a housing.

To reduce the need for a central vertical column at the back of the machine và to increase the rotational stability I chose to lớn use one rail on either of the back extrusions. As a consequence, these will require alignment, but this is much simpler than aligning 4 rails.


Step 5: Bed


*

The main construction of the bed is an 8 mm thick aluminium tooling plate that has been machined flat. The thickness of the bed makes it somewhat heavy but gives it significant thermal mass meaning it can maintain a very stable temperature. Its thickness also means that it is resistive khổng lồ warping as it undergoes heating. A 20 mm margin is added around the build area on the bed so that the additional cooling effect that the edge of the plate will see isn’t within the build volume. The tooling plate sits on a frame made of 2020 aluminium extrusion which mounts it lớn the linear rails and screws of the Z axis. The bed is mounted to the frame with 3 screws khổng lồ prevent the screws from over-defining the bed, but this will not scale well to lớn larger machine sizes.

A 200 W DC silicone heater is bonded lớn the underside of the bed to lớn heat the assembly và improve bed adhesion. The 200 W heater was selected khổng lồ limit the heating power of the bed lớn an acceptable max temperature. An AC powered bed would offer a higher heating nguồn but comes with the added risk of having to lớn run mains cabling and a grounding loop through the printer while the increased heating power could cause permanent damage lớn the printer in the sự kiện of thermal runaway.

Aluminium tooling plates và silicone heaters come with a significant cost so save a bit of money they can be replaced with a much cheaper PCB heated bed. These beds often have issues with flatness, but this can be overcome with software mesh compensation and will act as a suitable stopgap.

I wanted to have an easy way khổng lồ remove large prints from the bed & the ability lớn quickly switch build plates to lớn enable back to back print jobs. A removable bed is the obvious answer and so I opted for a spring steel sheet held down with magnets. This allows it khổng lồ be easily removed và reinstalled without the needs for a complex clamping arrangement. A magnetic sheet is bonded to lớn the bed for a quick solution.

The print surface is essential for getting prints khổng lồ stick to lớn the bed & preventing them from warping. I wanted to avoid surfaces like glass or bare metal that require excessive attention such as the application of hairspray, glue or blue tape for adhesion. The spring steel sheets are instead coated in PEI which creates a very good surface for adhesion when warm but will release the part easily once cooled.


Step 6: Extrusion System


*

The extrusion system of the printer is responsible for the flow of plastic out of the nozzle & is comprised of the extruder, the hot end, và the connecting parts.

Extruder

The extruder is the part of the extrusion system that pushes the filament into the hot end. There are many options on the market, but I chose khổng lồ go with the Bondtech BMG for its duel drive hobbed gears that nearly never slip on filament và the 3:1 gear ratio that gives finer control of the filament flow with less velocity ripple.

Hot End

The hot end is where the plastic is heated & extruded out of the nozzle và is made of the cold side (typically a large heat sink to lớn dissipate heat), the heat break (responsible for separating the hot và cold sides), và the hot side (formed of a heater block & nozzle). The key factor in hot end design is a sharp hot-to-cold transition khổng lồ get the best control of the flowing filament.

I chose lớn use an E3D V6 hot kết thúc for its proven track record và ubiquitous mounting solution. I upgraded the standard stainless-steel heatbreak khổng lồ a titanium one for the reduced thermal transfer. For the nozzle I chose a standard 0.4 milimet brass nozzle lớn start with due lớn its all-round performance. A big advantage to lớn the E3D system is that it gives the option of upgrading the hot end in the future to lớn allow faster printing with a “Volcano” heater block, support for abrasive materials with hardened nozzles, or a range of nozzle diameters for varying print requirements.

Other options worth looking at are the Hermera from E3D for a compact direct drive solution or the dragon from Triangle
Labs for quick nozzle changes & improved heat break performance.

Drive System

With both the extruder và hot end selected all that is left is to connect them together. The obvious answer is a direct connection using the groove mount connection, but this means that the weight of the extruder & its motor must be carried by the head. To lớn overcome this a bowden system can be used which places the extruder (and its motor) on the printer frame và feeds the hot over via a bowden tube. Whilst this reduces the amount of control over the filament, it allows the head acceleration lớn be increased and reduces print artefacts.


Step 7: Electronics


PSU

The first obvious question is the supply voltage for the printer of which both 12 V và 24 V are common. 24 V requires lower (half) current khổng lồ deliver the same amount of nguồn through your wires. This lets you use thinner wires saving a bit of cost & making cable routing easier. It also means you can use higher powered heaters khổng lồ reduce heat up time và increase top temperature. This is particularly useful for your heated bed. Your motors are a high inductive load on the printer và so having the increased voltage also means you can run them at higher steps per second (useful for 0.9 deg steppers) and at a higher torque which can greatly improve the unique of your prints as the motors can maintain better control.

Overall there is no reason lớn opt for a 12 V supply at the time of writing this. As the tech develops it is likely we will see the extinction of 12 V printer electronics in favour of 24 V & perhaps even higher voltages. For this reason, I decided lớn pick up a 400 W 24 V PSU from Steppers
Online. I chose a 400 W PSU as it covered all of the nguồn requirements for my machine with a bit of head room which will reduce electrical strain on it extending its life a little.

The Duet Wiki has a great article on calculating the required power nguồn for a 3 chiều printer PSU.

Control board

There is a wide range of suitable control boards on the market. 32-bit boards offer a serious improvement in processing power.

The Duet 2 offers a powerful 32-bit processor and the built-in drivers implement excellent passive cooling, but the key benefit is the tight integration with Rep
Rap Firmare (RRF) & its Wi-Fi interface which offers very powerful printer customisation and setup. RRF opens up a lot of possibilities and thanks khổng lồ its ‘GCode everywhere’ attitude it is easy khổng lồ implement advanced features & configuration. Duet 2 Wifi also supports 12 V and 24 V input và supports 5 drivers (capable of 256x micro-stepping) & 3 heater channels (2 for hot kết thúc tools and another for a heated bed).

I opted to run the printer without a screen since the Duet website Control interface offers all of the control you need & can be accessed from any PC or mobile on the same network as the printer. I have a PC next to lớn the printer making the Pannel
Due that is the preferred screen for the duet unnecessary.

Motors

Stepper motors are extremely common in 3 chiều printing due khổng lồ their ease of open-loop control (control without a feedback system), excellent low tốc độ performance, và accurate positioning capability. I selected lớn use NEMA 17 motors with a step-angle of 0.9º step angle throughout the entire machine. The increased step resolution over typical stepper motors gives finer control and smoother motion but also has reduced torque & top speed. To compensate for this, I chose motors with a 2.0 A rating which allows more current lớn be used to lớn recover some of the lost torque & the high step rate of the Duet Wifi should allow a reasonable vị trí cao nhất speed lớn be maintained.

Wiring

High flexibility silicone wiring was used throughout the machine as there are a large number of moving parts & the silicone wiring offers a superior life when being constantly flexed. Making the right selection of wire thickness is also essential to lớn ensuring that the load on the wires is safe. I used 20 AWG for all of my low current connections và 14 AWG for my bed connections. This will provide a small safety margin over the expected current.

All wires are fixed at both ends with cable anchors khổng lồ reduce the chance of them becoming loose & mains wiring is contained within plastic conduiting. This provides essential protection from wires creating shorts or bringing components lượt thích the frame live. Drag chains are used to manage the cables on the Z axis to lớn keep the wiring tidy và prevent it getting trapped in the motion system.


With the kiến thiết finalised its time to order the parts & start building! Before assembly it’s always good practise lớn run through the assembly process in your CAD package lớn help iron out any final issues and familiarise yourself with at least a rough plan of what you are going khổng lồ do, how you will bởi it và in what order.

Special attention is required in the assembly of the chassis to lớn ensure rails don’t bind, và prints come out square. A critical area is ensuring flatness of the đứng đầu 3 members so that the linear rails can be installed with minimal issue. I worked from the đứng đầu down using a table to lớn hold the extrusions flat khổng lồ a common plane. Ensuring the squareness of the top frame is also essential for good motion (although a small amount of error can be corrected in software). An engineer’s square is an essential tool for this. If blind joints have been cut non square you can correct them by adding small shims into the joint or rotating the extrusion 90 degrees to lớn shift the error khổng lồ a less critical dimension.

Installing the linear rails that are operating in pairs (Y axis and Z axis) requires careful alignment khổng lồ ensure smooth running. There are several methods lớn align the rails but the easiest method I have found is lớn denote one rail as the master và another as the floating rail. With the master rail securely fixed to the frame the other rail can be aligned using a Dial thử nghiệm Indicator. If you don’t own a Dial chạy thử Indicator the rails can be aligned “close-enough” by sweeping the axis back & forth ensuring smooth motion as you tighten down the floating rail.


With the machine built, wired, và powered up all that’s left is lớn calibrate it! There are quite a few calibrations steps required when setting up a printer but here I will outline a couple of the key ones. These calibration steps consist of brief descriptions of the calibration process and so will require an understanding of GCode & your machine to enable you lớn carry them out.

XYZ Steps Per mm

The steps per milimet define the axis scaling và so accurate setting is required khổng lồ get parts that are dimensionally accurate. Several methods exist based on the measurement of printed artefacts such as calibration cubes, but these can often introduce inaccuracy due to lớn the inclusion of errors from the printing process such as thermal contraction of the plastic, flow of the plastic, and surface defects like layer misalignment or Z-wobble which aren’t accounted for. Better tests use a stepped artefact that allows multiple measurements to be taken and consistent errors to be detected & removed. While these tests still include an error, they are typically sufficient for printing.

A good stepped axis calibration demo along with ready-made excel sheet khổng lồ calculate your steps per mm can be found here: https://www.thingiverse.com/thing:2484766.

Stall Detect Homing

Stall detect homing is a great feature as it can simplify the amount of wire runs you have lớn make around your machine và saves you from buying extra homing switches. It does however have the drawback of reduced homing accuracy (especially on Core
XY machines) meaning your ability to locate items on the bed may be limited. Fortunately, I don’t have khổng lồ accurately locate anything on my bed, so I chose to lớn use it.

The calibration procedure is relatively straight forward but relies on repeated testing khổng lồ narrow down both the optimal current và stall detection sensitivity.

Step one is to slowly reduce stepper current whilst moving, at the homing speed, around the bed. The aim here is to lớn find the lowest motor current that will reliably allow the motors not to lớn stall during miễn phí movement. Make sure you thử nghiệm all of the areas of the XY movement in case one area is stiffer. This lowest motor current that still allows reliable movement will become the motor current used for homing moves.

With the motor current phối we next want to lớn set the stall sensitivity khổng lồ the highest sensitivity that doesn’t cause false positives. We can vị this by setting the sensitivity to lớn the highest setting & repeat the previous movements around the bed. The motor will detect a stall as soon as it starts moving so reduce the sensitivity slowly until you find a stable sensitivity that doesn’t cause false positives. You now have the optimal sensitivity và motor current và you can use these khổng lồ write your homing macros.

Z Probe

The machine uses a PINDA probe which is an inductive probe with a built-in thermistor to allow for measurement temperature compensation. The Z probe requires calibration lớn get the perfect first layer. Start by fixing the probe khổng lồ the machine so that it triggers before the nozzle hits the bed but is higher than nozzle itself. You can now use the Z-probe to home the machine. Find the Z probe offset by moving the Z axis up to lớn the nozzle using a piece of paper lớn set the correct distance & finally set the Z offset for the probe to lớn the current position of the head in the Z axis.

E-Steps per mm and Flow Rate

Correct control of flow through your hot kết thúc is essential lớn consistent layers. First, we can mix the E-steps of the extruder which describes the movement of filament through the extruder before the hotend. Start by marking a point on your filament and measure the points distance from the start of your Bowden tube. Extrude or retract the filament by a phối amount và then remeasure the distance from the Bowden tube. You can use these two measurements khổng lồ calculate the correct E-steps using the formula above.

Different filaments often have different hardness and therefore change the effective diameter of the hobbed gears. Setting flow controls the extrusion out of the nozzle allows you lớn finely adjust the extrusion based on varying filaments khổng lồ compensate for this effect. Start by printing a single walled cube with no đứng top at 100% flow. This will give you a single wall thickness which you can measure with a set of Vernier callipers or a micrometre. You can then calculate the appropriate flow using the formula above. Adjusted flow should be between 90 % và 110%. If you need lớn adjust the flow more than this, it suggests other issues are present.

Tolerance Test

A final thử nghiệm that is useful to complete lớn characterise your printer’s performance is a tolerance test. This tells you the minimum clearance you can leave between parts before they become bonded together. Several quick and easy khổng lồ print tests exist online. I personally like this one since it is quick khổng lồ print & doesn’t use a lot of material: https://www.thingiverse.com/thing:2949885.


After building the machine I am very happy with the performance & test prints have come out with excellent quality. Due lớn COVID19 the delivery of the tia laze cut panels was delayed và so they were not installed in time for this write up. Hopefully they will arrive soon though!

This machine is far from a ‘final design’ & a version two will likely be made that iterates on some of the lessons learnt from creating this machine. There are a few things I would change about this machine. First, I would opt to lớn use microswitches for axis over stops. Although they require more wiring the configuration is much simpler, they are significantly more reliable and produce less false positives. Another key issue with the machine is the lack of a common datum which makes alignment of rails và screws challenging. Building everything against a common datum plane that can be guaranteed flat would help make assembly much easier. I would also adapt the Z axis to lớn offer more support to the bed by mounting each screw khổng lồ its own linear rail & mounting the bed through a kinematic coupling.

I hope this article has been interesting and given you some pointers on how lớn design your own machine. I found the project to be a huge learning experience but one that I enjoyed, and I certainly picked up a lot of new machine design skills. If you build your own printer leave a comment. I’d love to see what you make!
