Picture of DeltaTrix 3D Printer
The DeltaTrix 3D printer is a capable and novel 3D printer, designed to be simple in construction, yet effective in functionality. It it fully Open Source, so feel free to post improvements on the Instructables website, just don't forget to let me know in order to put links in to your own instructions...

Many thanks to Barrie for doing the video! Also thanks to Jason Mahar for publishing his song 'Pumped' as copyright free music.

Update (11th of January 2014): I replaced the main image with a photo of a DeltaTrix 3D Printer in black. This also represents the machine on offer in my Kickstarter campaign. Several improvements have been made since creating the initial printer. I will soon make updates to this instructable, in order to document these improvements. I will still make the files available for the initial version, but might organize them in a better way.

A change log is attached to this first step. Current version: V0.12

PS. Just so you know, I applied for a trademark for the actual name 'DeltaTrix '. I have no problem with anyone referring to the name DeltaTrix, as long as they do not try to sell anything as being 'DeltaTrix'. By all means, refer to your thing as being compatible with DeltaTrix, just do not sell it as being a DeltaTrix. Thanks, Richard.

ok i have some questions 1 can i just router the frame because i dont have a cnc machine and how much money did you spend on this total

RTegelbeckers (author)  MarkB162 months ago

To router the main parts for the frame would be fairly difficult, as accuracy is essential. The design has been created to make use of the precision a CNC can offer. As long as the panels are correct, the frame would allign by itself. However, anything is possible! If I would not have had access to a CNC machine, I probably would have tried a router as well, making use of jigs or other methods for achieving the desired accuracy. In regards of cost, check my earlier reply to SeppePuelings (about a month ago, on this page).

Hello I have wanted a 3d printer since I heard about them but I couldn't afford one, I am 12 and have advanced electronic but basic arduino skills, could you please put a list of all the parts with specific names, it would make my year, Thanks.
RTegelbeckers (author)  EpicNickRocks2 months ago


There is a BOM (Bill Of Materials) in step 6. Check it out and let me know if you need more information. Good luck!

I am now ready for the testing phase of my 3d printer! Any chance you could send me those files for arduino? Thanks so much for putting this instructable up
RTegelbeckers (author)  bpetno2 months ago

Hi, sorry not to have replied earlier...

Send me a private message with your email, and I will send it to you. I still have not fully cleaned up the code, so I do not yet want to publish it properly.

Looking at your design, I am hopeful now that a 3D printer is a possibility.

Quick Question: How Do I procure parts when I dont have any one nearby who can 3d print? I do have someone who can laser cut acrylic or wood. Does the geometry of the 3d parts lend itself to a laser cut? which are the parts I can laser cut and which I can machine on a lathe or mill?

RTegelbeckers (author)  rupin.chheda3 months ago
The upright panels for the machine frame need to be machined with a (CNC) router. The other panels could possibly be cut by other means, but all the laser cutting machines I know of cannot cut the thickness required.

In terms of the 3D printed parts, some could possible be cut on a (CNC) mill using a 3mm straight cutter: spacers for the switches, brackets for idler pulleys, linear carriage brackets (no. 1) for clamping belts, motor brackets, nozzle bracket. The linear carriage brackets (no. 2) for holding the rods and the end nozzle carriage would be difficult to machine.

At the moment I am running a Kickstarter campaign where I am offering the DeltaTrix 3D Printer in kit form. It is also possible to just get hold of a panel set. If other options would be required, ask and I could add them, eg. 3D printed parts only, or panel set + 3D printed parts only. The Kickstarter will receive a big update in a few days, so make sure you keep an eye on it!

Thanks for the advice on the linear rods. I am using 8mm steel rods about 30 inches long. Would that present any sort of a problem? And thanks il wait until you publish the firmware
RTegelbeckers (author)  bpetno3 months ago
The Rostock 3D printer uses similar size rods. There will most certainly be some deflection, but as plenty of peoples have been using Rostock type printers I am sure you will be able to get away with it.
bpetno3 months ago
Is there any way you could send me the arduino code that you made for this printer? Im really horrible when it comes to coding. Being 15 i havent taken coding classes and dont know how to make that part of the printer. If you dont want to give out that code its fine. Thanks!
RTegelbeckers (author)  bpetno3 months ago
My firmware is not yet ready for publishing, as it needs some cleaning up. When the time comes - which should be fairly soon - I am planning to publish the documented code on this very Instructable. Together with the publishing of the code, I will include full instructions on how to setup the printer and how to make changes to the firmware. If you really cannot wait a few days, send me a Private Message with your email address and I will send the 'dirty' files by email. PS. As you are building a printer with linear rods, make sure the rods are thick enough and not too long, otherwise their deflection could become an issue.
bpetno3 months ago
Thanks to you i was able to design my own printer and am currently building it. Dude you are my hero. Haha im using linear rods instead of your slide though because i do not have access to a cnc machine. Thanks aton and good luck with your kickstarter!!!!
Vika84 bpetno3 months ago
Nice one! Good luck with your build if you decide to publish it, send me a link!

Oops, I made the last comment whilst the PC was still logged on under my wife's account...
I cant download the parts spreadsheet ? Theres something wrong with the download link I think ? Could you fix it please ? Thanks !
RTegelbeckers (author)  Instrumentalist3 months ago
I just checked the link and it was working fine. Do you have Excel installed properly? I suggest trying again and if is still does not work, send me a Private Message with your email address and I will send it as as an attachment. Cheers, Richard.

Good news, my Kickstarter project has been accepted! I will be launching it on the 26th of December 2013 at 18:00 pm GMT. Have a wonderful festive season and the best wishes for 2014!

Sir what were the dimensions for the base and top. I am building one of these and dont have a CAD to open your designs in. Thanks!
RTegelbeckers (author)  bpetno3 months ago
There are a few free viewers available for download, which will be able to open the zipped *.dwg file from Step 3. I recommend Autodesk DWG Trueview if you are running a Windows PC, but there are also other alternatives available from Autodesk.

If you have to do with older hardware, like me, the latest viewers can be a little demanding. In this case it could be best to use the 2008 version of DWG Trueview, as located on

Use a viewer to take the measurements, straight from the model. If you have too much trouble with this, let me know as I might consider publishing proper engineering drawings for the panels.

Good Luck!

Just to let you know, I just submitted a Kickstarter project and started a forum topic in relation to this.

Let me know what you think about it!

very nice, how much do you think it would cost to build one? wich arduino board did you use?
RTegelbeckers (author)  SeppePuelings4 months ago
The biggest issues with building a printer, will be getting the CNC machined panels and the 3D printed parts. You will need access to a fairly large CNC machine and spend some time programming it. Also, as a standard 8x4ft piece of plywood will yield panels for three machines, there would be a lot of waste if you only needed one set. The best way to get 3D printed parts, is by using a friend's 3D printer. Online printing services would be fairly expensive (I actually did win my first set of parts in an Instructables contest!). As a one off, it would cost upwards of £550 for all the other bits, on top of the cost for CNC machined panels and 3D printed parts. As the electronics I used RAMPS v1.4 and an Arduino Mega 2560 R3. On my friend's machine we actually used a non-original, compatible Mega.

Excellent! I now wish I had a CNC machine and 3D printer so I could make this :-(
RTegelbeckers (author)  Macflame4 months ago
You could potentially make your own CNC machine, using one of many designs on this site. 3D printed parts could be done by a friend with a 3D printer, or they can be ordered from a place such as Sculpteo or Shapeways. - I did get my first printed parts for winning a contest on Instructables. - Alternatively, I will be making a kit available on Kickstarter VERY soon... ;-)
Good luck with the Kickstarter. I am sure your printer will be very popular.
RTegelbeckers (author)  Macflame4 months ago
That thing is amazing, I designed something close to that about a year ago, yours is FAR superior lol, do you have even a ball park guess as to what the cost of the kits will be?
RTegelbeckers (author)  kalboon4 months ago
Thanks for your kind remark. The cost of the kits will be revealed soon now, as the Kickstarter is almost ready to be launched...

Hey great job on the instructables!! If you had a kit for this I would buy them all. Do you by chance have that code cleaned up? Also, what were the motors you used for the belts to move? Cant wait to build this keep up the good work!
RTegelbeckers (author)  area364 months ago
Thanks! Although the code is working, it still needs a bit of cleaning up. I also want to try the automatic levelling thing, using a simple and cheap optical sensor and a mirror in stead of glass print surface. The motors are 17HS19-1684S NEMA 17.

How much does this cost?? Absolutely brilliant. Im fifteen and am thinking about making one
rakde5 months ago
I want a kit. Awesome
RTegelbeckers (author)  rakde5 months ago
Thanks! Coming week I expect to have the delivery costs worked out, after which I am hoping to go live on Kickstarter. I am looking at offering kits, not assembled printers. Should fit in with the Instructables ethos that way! :-)
Peter_Karlsen5 months ago
Brilliant!!! Could you add a video of the printer in action? I would really like to see it running.
