So you’re looking for the CAD download files…… Well E3D has finally released the files. You can find the files at their Github. https://github.com/e3donline/ToolChanger
E3D ToolChanger Assembled
The E3D tool changer files are published on github but if you’re looking for the assembled files or toolchanger assembly check out EJaworenko on Thingiverse here.
“E3D released their ToolChanger printer design to be open source! Exciting times. I went through the process of assembling the entire printer as a way of studying what they did and why they did certain things while designing a printer based off of it.” -EJaworenko
- Fusion 360 F3Z files
E3D ToolChanger Enclosure
Gregory Holloway published the enclosure design on Thingiverse along with many other E3D Toolchanger files such as the ASMBL Subtractive Tool. Greg’s laser-cut acrylic enclosure design is for the ASMBL Subtractive Tool. Check out Gregory’s Thingiverse here.
E3D ToolChanger Clones
While E3D has been perfecting their motion system and toolchanger design it take long for the clever engineering detectives that make up the Reprap community to reverse engineer the motion shystem. Makers have been developing tool changing techniques before E3D changed the game with their new machine. The concept has been presented in many ways but since the E3D MRRF 2019 presentation many inspired designs and clones have appeared. The best one that I have seen is by a Thingiverse User: TPRA.
First tests here :
Still work in progress :
“I’m releasing this now even if not definitive because people asked for it, but it’s still a prototype.” -TPRA

Although this page will be used to document and collect resources to implement a toolchanger on the SolidCore printer, we’ve only completed one so far for this case study. The following design analysis is discussing a toolchanger project we prototyped for our customer, Nandan. The majority of the topic currently being discussed is of the

CoreXY Belt Routing One of the most important parts for corexy movement is belt routing. Here’s a guide to the mechanics of corexy belt routing pulley layout in order to get accuracy and constant belt tension. Belt Routing Methods There are two main ways to implement the corexy belt path. Either a stacked pulley arrangement
With so many 3d printer kits and open source build plans available, it can be a challenge to choose an option for your 3d printing needs. Every 3d printer design has different design goals for different needs as well as different compromises. Whether you’re building a new printer or just in need of a new
Midwest Reprap Festival 2019 was wven more than the year before. There were so many more people attending and exhibiting. The venue was packed to seams with the coolest 3d printer builds you ever seen.
CoreXY Kinematics Explained? The corexy kinematics mechanical arrangement includes a unique motor movement where the X or Y motor move together or opposite of each other to move the carriage from left to right or towards or away . If you were to move just one motor you would see the print head move diagonal..
CoreXY Scalability The scalability of a core-xy printer can be an issue when it comes to hardware design and implementation. An increased belt path can also introduce problems resulting in artifacts in 3d printed parts. A rigid gantry setup is needed and proper binding is a must. 9mm and 12mm belts are available to account
There are a few different types of 3d printer kinematics to choose from, with cartesian kinematics being the most common. Recently the corexy architecture has become more popular. In this guide, we will compare corexy vs cartesian kinematics in terms of their speed and print quality so that you can understand the difference in each
How To Wire The Duet 3 Mainboard 6HC The Duet 3 is a great board for your 3d printer, but wiring it up can be confusing. This tutorial will walk you through how to wire the Duet 3 mainboard 6hc to your Workhorse 3d printer. Duet Wiring Instructions This is a guide on how to

What Size Stepper Motor Should You Use? While the size of a stepper motor is just the footprint it’s the winding that determines torque. There are Nema 17’s with as much torque as a Nema 23. Most 3d printers use stepper motors to drive z-axis motion lead screws to raise or lower the bed or
Are linear rails better? Linear rails produce a high degree of accuracy and stability compared to round rods with linear bearings. They have better mounting, and smoother motion which improves print quality and machine reliability. What are linear rails used for? Linear rails are used in different applications in industrial machine and motion system design.
We first discovered RailCore Labs and their beautiful corexy design at MRRF 2019. The Railcore 3d printer was designed by designed by Tony Akens and J. Steve White when discussing an idea of a core xy printer with linear rails on the x,y and z-axis on Reprap IRC.
Although there are many 3d printing and additive manufacturing conventions, there is nothing better than Rapid Event. The RAPID + TCT conference, also known as Rapid Event; is a worldwide known 3d printing show / conference in North America. You can find some of the most influential additive manufacturing companies that attend each year ath
Maker Faire is a interesting gathering of makers and creative people who enjoy learning and who love sharing what they can do with the maker communnity. If you enjoy technology and the DIY approach to life you’ll fit right in. Engineers Artists Scientists Crafters Re:3D Gigabot Large Scale 3D Printer re:3D showcase their new 3d
How can you calculate the wire gauge and length for 3d printer wiring? Most 3D printers use either 12V or 24V. The hotend of a 3D printer may draw up to 4A, while a heated bed draws nearly 12A. If the wire is not large enough or longer than needed, it will have more resistance
Layer Adhesion Layer and surface adhesion is a critical component of 3d printing. 3d printing issues increase as object size increases. Large 3d printers can be more difficult when it comes to bed leveling. As the extruded layers bond together they are fused with heat. Proper surface adhesion decreases warping that can decrease part quality.
Additive Manufacturing or AM rapid prototyping continue to advance production 3d printing and offer solutions for manufacturers with applications in additive materials and software. Additive Manufacturing Rapid prototyping and additive manufacturing has came a long way over the years. Professional 3D printing to large format metal 3d printers are advancing capabilities of additive manufacturing allowing

BigRep has been an industry leader in professional large scale 3d printers for a while now, and we had the chance to see their new machines at Rapid Event + TCT additive manufacturing convention. They showed off two of their printers they had on display: BigRep Studio and the even larger version, the BigRep One.
