This is the largest printer I have found. It is also the cheapest. The reason is that it is run by hand, without computer or motors or electronics. Put an object on one side and move the 3d pen while tracing the object. Move the z dimension by turning the crank on the lab jack to move the printed copy down a notch. Be creative!

A Laut3k derivative that goes for volume and large number of print materials at the same time. Using OpenBuild linear motion systems to get away from belt drives.

Building upon the great work done by Marshall Peck and others. I have started a new build.

This is an inexpensive build, large volume 2225 cubic inch, CORE XY 3D printer providing decent speed with precise and repeatable precision with expandable features.

3d Structured Light Scanner with Arduino Controlled Turntable

Hi! This build is, or at least should be, a multipurpose box (mBOX). Due to limited space I want to build something that can serve multiple purposes such as 3d printing, 3d scan, plexiglass cutting and hopefully some milling too (both wood and metal). Switching between modes should involve switching heads and worksurface (change heatbed with a wood platform and viceversa). (for the scan part I'm thinking of integrating this opensource project into the frame: http://www.freelss.org/ )

Building a Delta-6 variant, using recycled parts from a WolfStock Delta printer.

High quality e3d parts with a minimalist design

Please, look over my build and make any recommendations you can think of! I haven't figured out how long my arms need to be yet. Nor have I done any shopping around to find better prices...

I've owned some pretty unreliable printers, and I'll leave it at that... This design comes from the need to have a 3D printer that is reliable, period. I didn't have the money for a several thousand dollar 3d printer with an equivalent build area so that was out of the question. Plus as a fledgling Engineer, I really wanted to blood myself on a project. And that's how Old Faithful came to be. A simple, reliable, rigid, durable machine. Made by me :) Also, it'll be tough enough for light CNC.

After use of the i3 Prusa 200x200x180, the volume increases to 300x300x450 on the V-Slot and driven by a Megatronics V3

3D Printer based upon 3d printed parts and open builds componets

It all started after my prusa i3 build inspired me to experiment with resin 3D printers because I want to learn if they are worth it and if I can design my own printer.

I will post soon some more details.

First CoreXY. Simple Square build, hopes for faster movements.

A 200mm x 300mm x 200mm workhorse that never needs leveling due to Posi-Drive Leveling design.

PeeNaPle_V1.4b is a BoB controller board for 3D Printers, CnC and cartesian machine, using the latest Teensy_4.1

Belt driven 3-axis linear system for high precision and low costs. > Threading and linear real cutting needed

Berrybot inspired delta 3d printer with a few other tweaks and modifications.

This is my 1st submission to openbuilds.com and my 1st venture into building a 3D Printer. The Phoenix 3d Printer is a kit from Ez3D, a company based out of Colorado, started and backed by successful Kick-starter and IndieGogo campaigns. The Phoenix 3d Printer kit is currently backlogged 10 to 12 weeks which means quite a wait. I will be chronicling my experience with this kit as I get it done.

Realisation of my idea about a foldable collector for rainwater, which is light and easy to make. People around the world need water and can collect rain water with this collector. I made it for syria and all too.

Custom build plate for 300mm x 300mm (12"x12"). The hole pattern is for the 20x60 V Slot

I am hoping to post a detailed build of my printer it is a large format using the RepRap RAMPS 1.4 & Mega 2560 & DRV8825 Driver + optical end stop +LCD 12864 -C 0.4mm Far-end Distal Dual-Head Nozzle Extruder Double Nozzle

build is in process the machine went together perfectly no issues at all but the software is another issue I have been trying to get the thing dialed in it is driving me nuts I'm still in the process will update if I ever get it figured out

Corexy, with possible head change (3d, cnc, laser)

Leveling Platform / Stand 3D Printers

Fascinated for some time by 3D Printing. Now, after studying countless forum posts, blogs and similiar stuff, i want to Start with my own build. Maybe a bit much but usually i thrive with the challenge.

I need a large build plate without spending 10-20k for a "store" built printer.

This is a Delta build using 1610 ballscrews from China

This is a big 609 x 609 x 914 3d pritner with exchangable hot ends and extruders.

This is my own modified version of the D-Bot printer. I wanted to spec this printer to be able to print exotic materials at high accuracy with little to no compromises and maximum reliability.

HE3D K200 kit build

I have parts that are apparently not suited to a cnc router or a 3d printer. I am still trying to figure out what to make out of what I have,

I want to have a printer to support senior projects. Also working on supporting 3D printing needs in the local community.

A DIY 3D printer. At beginning made from aluminium profiles, aluminium sheet and wood :)

How to modularize the 3D Systems Cube 3 extruder nozzle.

Toying around a concept. Inputs are welcome on whether to use lead screw or belt drive. My lead screw will be single start 500 mm lenght, 2 mm pitch and 2 mm lead. Nema 17 motors will be used. All veterans, suggestions please.

Just now in the planning phase of my build. Waiting for some parts to come in to see what I am going to build off of. Print area going to be close to 300x300x350. Trying to decide if I want it enclosed. I do want to print ABS... so probably so.

Make a vinyl burrito ENCLOSURE for your TEVO LITTLE MONSTER for < $30 (<$20 if you don't have your vinyl shipped!)

Cheap, experimental Modification to Tevo Little Monster's bowden system for the extruder

Super tall 3D printer. All lead screw design.

So I thought I would make the Leon van den Beukel version three 3D printed CNC Machine, it is the third incarnation so you would expect a relatively bug-free CNC Machine with a strong foundation.

This is the build of a cartesian 3d printer made of an old Anet and Geeeteck, some 2020 alu profil and linear rail. Powered by a Rumba with a Nextion screen. It should be modular and accept dual Extrusion and laser engraving.
