Open Lab Starter Kit

An open source set of machines for Fab Labs and Open Labs


What is OLSK?


Creating means to create.

Starting a digital fabrication workshop requires a set of machinery, which are often imported and unaffordable. The Open Lab Starter Kit is a project in cooperation with Fab City Hamburg which aims to create a repository of open source machines to be replicable locally and with lower costs.

OLSK Goals

Global knowledge. Accessible local production.

Develop Open Source Digital Fabrication Machines

Document the reproduction process

Transfer the knowledge behind the machines

Create fully Open Source Fab Labs (Open Labs)


Fill the gap between commercial and Open Source machines

Lower the barriers in accessing digital fabrication technologies

Include and enable anyone in the process


Boost the Fab Cities local production and circular economy


OLSK Machines

OLSK Small 3D Printer v3

OLSK Small 3D Printer v3 is an open-source desktop 3D printer with active cooled Core XY motion system and independent Z motors. The calibration automatically takes place before each print under 5 min with the Eddy Current Surface Scanner. It also features a built-in accelerometer, an enhanced cooling system with auxiliary part cooling fans, high flow nozzle and filament sensor. The housing is fully enclosed for thermal stability. To facilitate the maintenance, the magnetic beds are removable and the electronic compartment is easily accessible.

OLSK Large 3D Printer v3

Big format 3D Printer with printing volume of 1000 x 1000 x 1300 mm, making it the largest open source 3D printer.  Its housing is fully enclosed, with access on two sides. The bed system features an efficent automated modular heating and Eddy Current Surface Scanner,  with 1000 m/s travel speed. It has an industrial design, using linear rails on all axis, a quad-point self-leveling core XY gantry and a built-in accelerometer.  The kinetic joints enable a non-planar printing. It also offers local and remote access,  with customized Klipper firmware, touch screen, camera, LED status indicator, easy belt tensioning system and ethernet and WiFi connectivity.
