In my opinion, this is the easiest and most complete tutorial to walk you through building a large platform 3D printer and the Sketchup File is included for you to make any changes needed.. The Plastic Beast is a CoreXY Printer with a build platform of 440mm square. You can print 600mm or about 23 inches diagonal. Any level of user from novice to expert should gain something from my tutorial.

CoreXY printer heavily inspired by e3d's new open source printer with tool changing. I intend to make it so when e3d start selling toolheads these can be added to the machine without any major work having to be done.

This is a heavily modified system based on the RatRig V-Cast. Lots of personal touches, and a LOT more to come!

Large Core XY 3d Printer W/fixed build plate

A fully aluminium printer made from off the shelf components, no printed parts.

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

Transformation of an OpenBuilds Mini Mill into a convertible 3D printer / CNC mill with interchangeable tooling. Maybe a bonus conversion TBD.

High quality e3d parts with a minimalist design

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.

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...

Super solid core xy build inspired by the e3d tool changer

Building a CoreXY based 3D printer using primarily parts from China on eBay. Large 500mm frame.

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.

Fully OpenBuilds based Core XY printer design by Rat Rig. CAD files, build manual, build videos available!

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

HE3D K200 kit build

A Rigid Delta Printer using C-Beam screw actuators

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.

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

Someone donated a E3D Volcano to me (http://e3d-online.com/Volcano/V6-VOLCANO-POWER-PACK-175-UNIVERSAL-24V) and with a super hotend like that, it feels like a waste to stick it into a small 3D printer. So I decided I want a 320x220mm (XY) machine, 200mm Z is plenty for me
