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

It took me 18 long nights to build it

An enclosed cube shaped 3D printer using CoreXY motion. Fabricated from V slot extrusion, standard extrusion, aluminium plate and acrylic sheet using basic workshop tools. Using standard RAMPS/ Reprap electronics. Technically a 'Repstrap' currently used to build a true 'Reprap'

Coming soon

Combines the layout factor of a CoreXY while using Cartesian logic. The design has a fixed build plate - moving an X/Y frame on the Z axis enclosed by an outer main frame.

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.

What a way to learn about 3D printing

Building a Core XY printer with a fixed build plate from off the shelf parts.

The aim of this design is to build a simple, cost effective (under $1000) and relatively compact large volume (m3) 3D printer that will use a pellet extruder to create art/design objects using shredded recycled plastics.

Super Rigid CoreXY 3D Printer

This is a simple, yet rugged design, weighing only 6 lbs and with 13x13x14" volume with a 8x8x6" build area. While assembly is pretty simple, the small size and rigidity of the design make shipping assembled printers attractive.

A Cartesian printer using bushings for the Z axis instead of wheels or linear bearings. The design also synchronizes two Z axis screws with a timing belt for a level lift. The ratio of the drive pulley and Z axis pulleys produce .005 lift per full step on a 200 step motor, eliminating layer resolution "drift" caused by microstepping.

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.

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

This design should give the same performance as the high speed Ultimaker since it uses a similar ultra-light X/Y concept which eliminates any movement of both the X and Y motors to achieve X/Y travel.

I built a custom delta using 3, 1000 mm long C-Beam® Linear Rails and 3 C-Beam Gantry Sets. I had the bottom and top plates water jetted ( for accuracy ) out of 1/2 inch aluminum, from a design that I did in Fusion 360.

This is a breakdown of how I designed the UltiFaker 2 Go as well as how I machined and assembled it. I'll include a complete BOM and all of the drawings and prices.

High Quality CoreXY with focus on quality and optimized printarea versus physical size of the printer.

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.

This is my latest printer build. The second printer I've built using V-Slot.

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.

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.

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.

This my version of a large no corners cut Delta.

The build area will be fully enclosed. I anticipate using primarily ABS, and have interest in the soluble support materials as well. The main components to date include: OPENBUILDS - 3 x C-Beam™ Linear Actuator Bundle, 1000 mm, w/ Included NEMA23 Motor) Extruders (3) - [Sintron] 1.75mm Mini All Metal MK8 Extruder Hot End - reprap diamond Control board - RUMBA Stepper drivers - DRV8825 StepStick Power supply - eTopxizu 12v 30a

Mid range build.

My self-designed and built, tall-format coreXY printer with 300 x 300 x695 mm print capacity.

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.

Large 2 foot x 3 foot x 4.5 foot build volume Core XY printer build in process at this point. I am designing everything from scratch and using typincal parts bought from amazon for the build.

Tough 3D Printer using OpenBuilds Parts!

I creat a open source 3D Printer to print big things. Print size: 400x500x300 mm. You can download the Drawing in PDF and in Inventor 2013 format. The unwinding drawings are also included. I take some detail photos for a better understanding.

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.

Designed from the ground up as a low cost, highly scalable delta printer. This printer has been built as small as carry on luggage size, up to an 18in wide print surface and is capable of larger. Approximate cost is low to mid $500 range start to finish, including electronics for a basic model.

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

A New Core XY Printer build. BAFP stands for Big And Fast Printer. It will be awesome !!

The Roberta Clementine a proof of concept and progenitor to the series of printers I will be calling the Clementine Sisters. The printer is named after Pittsburgh Pirates baseball player Roberto Clemente. Although it is more accurate to say the printer is named after the school I work for which is named after Clemente the Roberto Clemente Charter School. http://www.myrccs.com Roberta is the first and not really built to last but instead built to test ideas and to produce the parts for successors

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.

Large scale True 500x500x500 build volume 3D printer.

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 beefed up modification of the TrueUp Kit project

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

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

A framing design for cantilever style printers

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.

CoreXY build

OneZ gets it's name from it's most unique feature - only motor for the Z axis while maintaining the stability of two bearing guides for the Z axis. Reduction to one Z motor eliminates need for auto bed leveling.

A CoreXY/Bowden design with a belt driven Z axis. This is a box design without the front end of the box, making the print area and maintenance, like changing a nozzle, easily accessible.

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

Dual X-Carriage CoreXY. Not impossible, but probably the only one. Use the link to Thingiverse "Hlidskjalf" for parts and downloads.

Light enough for high speed #3dprinting Strong enough for high speed #3dprinting

probably as big as you'd want it...

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

Dual extruder 3D printer and laser cutter.

A completely belt driven cartesian design with a center mounted X motor. This is a very compact, rugged design.

This build is inspired by the Lulzbot Taz printers and makes use of the new OpenBuilds C-Beam

Machined Aluminum MagBall Carriages

This is an experiment to build a Linear Delta Printer using four towers instead of three. Primary reasons: 1. Build area is roughly cubic vs roughly cylindrical 2. Greater speed and precision from additional control provided by fourth tower. 3. Symmetric kinematics from even number of towers.

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.

This is a modification I made to my Voxel Ox 3D Printer Z axis, which synchronizes the Z leadscrews via a shaft and helical gear transmission. It prevents the two Z leadscrew from getting out of adjustment relative to each other, and uses a single Z motor instead of two. This build is just documenting the specific changes I have made to the Z-axis, since the frame and other axes are still from the original Voxel Ox design.

Upgrading printers for Synchronous Leveling

Contains a further modification to Creality's poor CR-10 design

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.

A work in progress. working to refine the print head/carriage to integrate a bed level probe directly into the print head.
