We are introducing the Cairo Mini 3d-printer! It’s a DIY fully Open-source Reproducible 20x20cm 3d-printer. The original goal of the Cairo Mini 3d-printer is to create a low-cost 3d-printer below 220$(3500 LE). That anyone can build with ease.

Build using standard parts as much as possible, Open Builds etc. To keep printer usable for more materials will be trying a heated bed with rotary elec union for the thermistor and power.

I designed this 3D printer from scratch for my mechanical engineering capstone project. It's made for printing clay but should be able to print any paste material. The clay extruder system could be easily modified to work with almost any 3D printer. The printer is approximately the same size as an Ender 3.

All metal CoreXY 3D Printer Design with triple z, kinematic bed, and scalable corexy mechanism.

Well I built a C-Beam XL around a year ago, I am still learning things as I make stuff with it, it has been quite a wonderful learning experience. Now I have gained enough confidence and knowhow to Mill the required Plates to build an Acro Laser System using the Acro Laser Sketchup Model. I have pulled the Model apart in Sketchup, isolated the Plates and generated the G-Code to cut/Mill the plates. I have used Sketchucam to generate the G-Code. I Use Mach3 on my C-Beam XL to Mill.

Piranha CNC is a strong linear guide based machine based on a C-Beam rail construction.

First build of a Lead 1515!

This is the next version of Dash, now operating much closer to its potential. Please message me if you need anything, such as Simplify3D settings, material information, design intent etc. Since the Pack-and-Go zip file is fairly large (120mB), here is a link where it can be downloaded: https://drive.google.com/file/d/1Q3ygyo_tTrB4UYIV62_wtCSCbWuE3krT/view?usp=sharing Note: I use Solidworks 2022, acquired through their Solidworks for Makers program (check it out!). A super deal at $100/yr

The OpenBuilds Lead Machine takes us back to the roots of the OpenBuilds modular building system, and has proven itself as an adaptable design that can compete with any machine in its class!

This project is a Pull tester for material testing or structural testing with stress (force) data logging, I don't have plans for strain logging but that might be down the road.

I wanted to make my own Voron, so I made my own Voron,

I decided to start designing this printer, this will be my solution for a more rugged printer that you can use as workhorses...

Building the OB Lead 1515 was straight forward. The on-line OpenBuilds assembly videos were extremely clear and easy to follow. Initial build of this machine is with OpenBuilds BlackBox which simplified getting the electronics to work the first time. OpenBuilds staff are friendly and helpful.

This is a small desktop vacuum former that can be connected to a shop-vac and an electric heat source (like a grill for instance). You can control the time each appliance stays turned on, and the vacuum is automatically turned on when the tray is placed on top of the model. The vacuum table is 20x20cm wide, and I've tested it mostly with 1mm thick PET sheets.

Ball screw drive, linear rail CNC Kit

A lightweight, portable, accurate 3D Printer that has a good sized print area and small overall footprint that is easy to build, with easy to source components. The design is OpenSource allowing those with the capability to make their own parts get up and running.

Carbon fiber filament winder

I am currently 15 years old, from Germany and trying to build a low budged CNC router. I only designed this CNC based on other CNC routers that I have seen and what I am able of. It consists mostly of 2.3cm plywood to keep costs down. The size of the work area is approx. 40 x 80 cm. I would be really glad if you could give me advice's for improvement on the design and everything else ... ( I could really need your help :) ) enjoy :)

A Torch Height Controller helps improve plasma cut quality and can save a CNC Machine from crashing. This design doesn't require you to know electronics or need any custom circuits... Its plug and play! This is a COMPLETELY standalone controller with a built-in Driver powerful enough to run just about any stepper motor. (maybe a little to powerful for a NEMA17)

This is a upgrade to make a little deeper and a little bigger foot print for cutting. This is a copy of design off Rob Taylor idea for Dbl C Beam setup. The goal though is to design it around a new build with minimal tools for some one with no cnc access. Drillpress and drill bits and tap set. A 10in Non ferrous metal cutting blade for my table saw. Paper printer for printing DXF files.

The crypt-cube is another project I've been working on off and on over the past year, unlike my previous built C3DO this is a much smaller built with a volume of 318mm x 240mm x 220mm. With this build my main focus is precision and speed.

A Sphinx build to inspire and encourage all those who want to get started with cnc to check out Opensbuilds line of machine bundles and hardware.

A small form factor machine in a soundproof enclosure

While mimicing the frame platform of the popular Crealiy CR-10 and Ender series, the Vulcan MAX overcomes design weaknesses in both printers. Chief improvements are a more stable, rigid mounting of the Z frame and Z gantry.

Super cool standalone Human-Machine Interface for controlling your CNC machines!

It startet in May with some leftovers from a cnc router build. Now in the middle of December its 99% finish. Everything is lowcost, spend about 1600$ so far.

The OpenBuilds Table Series offers a modular table structure that grows with your needs.

This is a Sphinx variation, aimed to minimize footprint and maximize workarea. Work in progress.

Easy to build,low-cost, CoreXY

A dual extrusion CoreXY printer with a 290 X 290mm build volume built entirely out of 2020 aluminum extrusion and using openbuilds mini-carriages for motion.

Another build based on the original OX design with a cutting area will be about 26" (680mm) x 50" (1300mm) and driven by lead screws.

The idea was to use materials from previuos failed projects into a succesful one. I have build this tiny but powerfull CNC machine mainly using the universal gantry plates for the X and Y axis. Also another innovative part is the fact that I assembled the Z gantry with 2 aluminum sections of 20X40 and one aluminum seccion of the 20X20. I used NEMA 17 stepper motors with GT2 pulleys. This was designed on Fusion360

We want to present you the new design of the device which is Router Sled. The whole structure is made of aluminum elements and ensures good quality of the device. We used V-SLOT aluminum profiles and OpenBuilds accessories for the construction. The instructional video can be found on our YouTube channel (subtitles in English soon)

Stabilus 3d Large Format Printer Kit

The X301 is a CoreXY 3D Printer that has a small footprint and a large 300x300x330 build area. The open style of this printer breaks the "Cube" mold of many other printers in this class but still retails rigidity and great performance.

China Router frame with linear bolts, Nema23 and the icing on the cake “open build parts“

A 1500x1200mm, 20mm rail and 1610 ballscrew, heavy-duty, four-axis gantry machine. As high speed as spindle power MRR will allow for. Approx 4 x 3 x 1ft travels, intermediate size between benchtop and floor-scale units. Aiming at $10-15k machine in the $3k region.

I am satisfied with my build and next one will be even better.

Machine with 12,5Nm closed loop steppers or servo steppers

Inspired by previous Sphinx builds by Sorin (w/ MGN Rails) and Kenneth's witthuhnCNC XKLBR-1S. I wanted to create a desktop unit that kept a minimal profile and neatly contained the PS, Controller, and all wiring, making it a singular unit that could be easily transportable (as it will be doing double duty at my home and at work)
