Ultimaker 3D printers are designed and built for Fused Filament Fabrication for various high quality plastics like PLA, ABS, CPE within a commercial/business environment. While this printer is delivered as a DIY-kit it is suitable for the education of 3D-printing. How does it work, what does the printer do? The multiplex housing is ideal for making all kind of adjustments. Although we achieved a very high standard in the reproduction of 3D-models with the usage of Cura, the user remains responsible to qualify and validate the application of the printed object for it’s intended use. While being an open filament platform the best results will be achieved with Ultimaker certified filament, while effort has been made in order to match material properties with machine settings.
