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.

An open source 3D printer design with a sturdy V-Slot frame

A 3D printer without belts, a print volume of 320x320x260mm, obviously the V-Slot as linear guide! and a maximum of printed pieces.

This is a work in progress(not printing yet). Expect this instructions to grow with time, but for now it is mainly interesting for those who want to take part in developing this printer.

A stable and strong 3D printer made of 16mm MDF and machined on my OX.

An easy Epic Win for novice engineers new to the RepRap project www.3distributed.com

This is a work in progress 3D printer Dimensions are 230x230x340mm height. Print dimensions are: 135x135x160mm. Prototype has a bowden extruder with a J-head hotend. Assembly instructions: http://reprapstyle.blogspot.pt

Delta printer that uses printed carriages sliding on aluminium extrusions.

This is Fina; My Lautr3k inspired build.

Over 840 parts. Of whom around 450 are screws and nuts, more than 100 parts are printed on a 3D printer, the frame consists of about 60 components. There is nearly 40 electrical components connected with tens of meters of wires, most of them sleeved.

Hell Yeah

Open source 3D printer with very powerful heated bed and light weight x axis design. Full source repository can be found here: https://github.com/a-drizzle/Printer1

This project is focused on developing a low-cost, portable and open-source FDM 3D Printer.

Large scale delta robot using c-beam as the core frame component.

Build Notes: Here are all the parts necessary to re-produce this design. Please note, all of the parts are either sourced through openbuilds or have been selected and printed from thingiverse.

I'm looking to build a large build-volume, accurate, steady 3D printer with the eventual aim of swapping in a diode laser to allow for use as a cutter for printing/cutting parts out of balsa sheet for building model aircraft.

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.

Mad plumbers choice what Else can i say?
