SmartrapCore is a low-cost, open-source wooden box 3D printer

SmartrapCore is the company’s second model and is even easier to assemble than the Smartrap.

As the popularity of inexpensive, open-source 3D printers continues to grow amongst the DIY community, Smartfriendz is hoping to help accelerate adoption with their latest device, the SmartrapCore. Touted as a “true RepRap printer,” it is capable of constantly improving itself by printing its own plastic parts and upgrades. Possessing the same ease-of-use as the French startup’s earlier Smartrap 3D Printer, Makers will be able to access online plans, instructions and assembly assistance through a series of tutorial videos.


However, in an effort to differentiate itself from the Smartrap, the team started the project with a coreXY base. (Hence, the “core” in its name.) The 3D-printed components are placed inside and atop of a wooden box, then simply screwed in using wood screws. As for its hardware, like a number of other RepRaps available today, the SmartrapCore is based on an Arduino Mega 2560 (ATmega2560) and a RAMPS 1.4 control board.


Smartfriendz shares that the machine is expandable from 20cm x 20cm to around 50cm x 50cm. More importantly, all designs are entirely written in OpenJSCAD along with various NEMA, rod, print and wood thickness sizes. All models are dynamically updated from parameters, while print plates will soon be automatically generated. Beyond that, the team has recently made improvements to reorient the stop on “new plate2,” as well as the J-Head attachment with its inductive sensor.

Interested? Not only can you now purchase the SmartrapCore online, you can also find its files on Thingiverse and Github.
