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.

Modular and Scalable CoreXY Printer with all metal parts.

Below are the details of my build and a good story for those who read till the end. Sorry for the grammar

Quick and Simple V-Slot Gantry System. This example build shows how easy it is to make a linear actuator using a few OpenBuilds Parts. You can mount this system an many ways so be sure to download the example models.

This is a remix of Marshal Peck's Voxel OX, with some design tweaks inspired by Makerparts and jjcolletta. It has a build area of 300mm X 300mm X 480mm, but is easily configured for just about any build area up to 500mm X 500mm X 750mm. I have used some laser cut acrylic plates and a couple of 3D printed parts in its construction, however it can be assembled using nothing but OpenBuilds parts with the exception of the heated bed and the Y axis carrier for the heated bed.

Functional real-world 3D printer build with RM2-2RS bearings in routed V grooves on phenolic resin rails (lab countertop scraps) and NSK 25mm linear rails/trucks.

Learn to build a super strong nema 23 lead driven linear actuator

Currently I have Velleman/3Drag K8200 modified and CNC machine self built and wanted to use both to make new 3D printer. After looking at different designs I liked Voron a lot and have decided to go that way. Currently I have ordered majority of parts and build shall start soon. I don't plan to rush it as I am usually 2 months home and 2 off. Today done some electronics. Looks ok. https://youtu.be/ls_tl54ruE0

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.

Massive Delta printer with a print area of 25 Inches (634mm).

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

Large format printer build based off successful small Corexy. I figured it could be scaled to large format and be portable. Portable meaning by removing a few pieces it could effectively be rotated out of a standard door frame.

The Phlatprinter 3 was designed to be used in a small shop with the ability to cut large sheets of foam for RC airplane projects. The idea was that you could save all of your aircraft as models and tweak to perfection after every flight.

Phlatprinter foam cutting CNC machines are awesome space saving mills that use a rotary axis as a sheet feed.

Dirt cheap build.

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.

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

Large Core XY 3d Printer W/fixed build plate

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.

The Space Optimized LAser Cutter is a 40 watt CO2 laser cutter that supports a maximum part volume of 24" x 16" x 6.25". It consists of a V-slot frame + brackets/mounts designed to be 3D printed on a consumer desktop printer. Total cost of the machine is ~ $1,400 USD.

The process from my bought printer, to a custom home built machine

I'm basically building a larger version of my crappy wanhao 3d printer. My work was recycling some aluminium extrusion and it broke my heart to see such nice pieces of aluminium engineering being sent to a furnace. Mega 3d printer was born!

This is a simple cantilevered 3D Printer. It is designed around the OB V-Slot linear rails. I am trying to simplify this as much as possible, all rails will be 250mm long and only one will require cutting (it will be cut in half). The printer will use all OB wheels and gantry plates where applicable, all other plates can be either Laser Cut or 3D Printed (files will be provided for both). I am not set on electronic as of yet, but plan to use a single control board...no Arduino/Ramps control.

A Large format 3D printer

Video on youtube: https://www.youtube.com/watch?v=vCTbLZ2_m-w&t=36s

Super tall 3D printer. All lead screw design.

This build includes the design of a large FDM 3D printer. This machine has a 796mm by 796mm by 900mm (LxWxH) build volume. Motion is controlled by servo motors and the printer runs on python-based marlin firmware.

A slightly more than one half cubic meter 3D Printer using V Rails, V Rollers, "C" Rail, mounting plates, and a bunch of 3D printed brackets to provide strength and stability to the frame. Rigidity was the goal and precision and accuracy the result. The software is a whole other topic, many weeks spent dialing that in to make the printer print.

I myself invented this concept printer form

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

Maximus Evolution : 380mm x 400mm XL 3D Printer

Ultimately - the design is based on the highly successful Ultimaker concept, for which a regular size costs in the thousands, and one of this size would be edging into the 10's of thousands. Expected Build cost - <$800 It is a X/Y Cartesian printer with Raising/Lowering Z axis (Hotbed.) - Overall size is 610mm x 610mm x 750mm - with build volume of around 450mmx450mmx450mm - and will also have the ability to change work tools - such as for CNC Routing, Lazer etching, 3d Scanning, etc.

This printer is a design that has evolved over three years. The original goals of this project were to design a rigid printer that had a large print volume, 300mm^3, with easily sources parts and a minimum of complicated printed parts.

OKMI 3d Printer based on CoreXY

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

3D printer with 7 drivers, compact, dual extruder, no CNC part. All Openbuilds and 3D printed part. This is purely experimental.

This is an all metal build using OpenBuilds V-Slot linear rails to produce a high quality and cost effective 3D printer. The printer is designed to be scalable for your desired build area and can utilize high quality hotends with 16mm groove mounts such as E3D.

This modular CNC machine is based on the OpenBuilds ACRO System, however I wanted something that did more than just laser engrave. So I designed my machine using the same style as the ACRO but with some upgrades such as an actual Z-axis and the ability for multiple tool attachments.

My first printer! I went for a simple cartesian design, based on evilc66 one. It uses 1000 mm C-beam linear actuators. The build volume is 700x700x700 mm^3.

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.

This 3D printer is an implementation of the Ultimaker 3D printer Using the Modular approach, many of the parts from the CubeSpawn 3 axis mill translate straight across into this design, so adding new concepts should go quicker

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.

I recently completed my C-Beam Plate Maker build ( http://www.openbuilds.com/builds/rsws-c-beam-build.4286/ ) and quickly got the build bug. I was looking for something to make with the new C-Beam and decided its time to venture into the 3D printer world. I can honestly say I have never been in the same room with a 3D printer, so this is going to be a learning experience. I spent some time browsing the 3D printer builds and finally decided to copy the Talos3D by AlexLee.

A smaller version of a standard D-bot. Smaller to fit better in my workable area and to fit my vision for the printer.

CoreXZ implementation on 3d printer using Openbuild and RobotDigg parts.

The 3D printer will be able to print 2x2x2m components and not just in PLA or ABS. It's not just a DIY printer but I'm trying to apply engineering formulas to make it. I'm going to apply the state of art for 3D printing and scannering existing.

This is my first attempt at building my own 3d printer.

I am building a simple home brewed printer. I have a background in industrial automation so I figured how hard could this be. The mechanical build was pretty smooth as was the electrical side. Now just getting plastic out the hotend is my stopping point.

The QuorXZ doesn't magically appear. It's gestation takes time, careful attention, and requires many parts. However, when it is ready, a magical, mechanical instrument is born....(and when you finally say its name, it sounds a little bit like "corks").

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

My first construction after many years buys ready devices.

just wanted to share my build of a huge 3d printer. It stands just over 2 meters tall and has a total print area of around 850mm x 850mm.

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

As a tinkerer and hobbyist I need a reliable quality printer on a budget... Meaning I'm not looking to buy a: Prusa, Zortrax or LulzBot because of the added cost their marketing adds. I can definitely build a machine of hopefully equal quality at a lower cost that is not impacted by the marked-up priced from a large reputable manufacturer. I will need to dedicate time and more time for design shakedowns to ensure I produce a quality machine. Bare with me on this build... Thanks!

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

Super rigid Delta printer, using 20X40 V-Slot

A steel framed 3D printer using a similar design with my CNC Router.

I have re-purposed many of the parts from my Linear OX build. I'm using MGN 12 linear rails on all three axis, 5 start lead screws on the Z axis and I'm going to experiment with 5 start lead screw on the X axis. The frame plates are made from 1/8" laser cut mild steel, & open builds extrusion.

im just starting and the size of this is 1.5 meter from base to end

The whole system is powered by 12V / DC power. Process it into Pellets or Granules to use it with your 3D Printer or Filament Extruder. Our self-developed steppermotor Controls allows you to optimally adjust Feedrate for your Situation. Forward, Backward and Stop is integrated for easy operation. The Speed can be continuously regulated via rotary switch.

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.

A cartesian build with a build dimension of 200x200x750mm. I will be using a dual extruder, heated build plate, and a screw drive for the z axis.
