Jonas and Simon Kühling are two German entrepreneurs that have embarked on a journey to develop a new, heavy-duty RepRap desktop 3D printer. Their newly released “Kühling&Kühling RepRap Industrial” 3D printer is said to address some well-known issues that exist amongst other desktop-grade 3D printers and RepRap designs, and their OpenSCAD source files are now being polished for imminent release through a github repository.
The background for their journey relates to having used several other RepRap printers over the years, and encountering many reliability and maintenance issues. This has resulted in the brothers coming up with a more durable and maintenance-free design. Their new 3D printer is optimised for building ABS parts, however it comes with all the necessary features to be able to handle other materials as well.
According to the founders their new design allows users to print ABS objects, using filament at 3mm diameter, without any warping problems and the 3D printer comes with a fully enclosed frame with recirculating chamber heaters. These heaters can raise the ambient temperature up to 70°C. which allows for the production of objects with minimal thermal stress and yield dimensionally accurate results.
The design includes two extruders for this 3D printer that can print with different nozzle diameters, which comes in handy when you need to save production time. Whilst one of the nozzles is printing the visible outer shell of an object in fine detail, the other bigger extruder nozzle can be used on the infill structure.
The ethos for creating this 3D printer was to create it for continuous heavy-duty use, with less maintenance required, so the expectation is that you can save time for several recurring tasks like swapping filament, changing nozzle tips or levelling the build base. The current build volume is 200mm x 200mm x 200mm and due to many requests the pair are already working on a new bigger design.
You can watch a time lapse video of the new “Kühling&Kühling RepRap Industrial” 3D printer building a fully supported 200% scale version of “oloid roller” at Thingiverse. For the full list of specifications and features visit the Kühling&Kühling website.
