Field report: 3D printer - Geeetech Prusa i3 pro B

created: 2022-11-04 from Bernhard

3D printer kits have become affordable. The new hobby can be purchased for under 200$. What you buy is a device that initially consumes a lot of time, but offers completely new possibilities. Once the printer is assembled, it's time for fine-tuning. I spent some time to choose the right software (Slicer) and to understand the different setting parameters. In addition to the kits, there are also pre-assembled models, which can save quite a bit of time during commissioning. In addition, the standa... ... continue reading

Why do I need a 3D printer? Admittedly, I also asked this question when I first heard about affordable 3D printers for the home. After a few years of use, this is how I would describe it: Even now, I don't know what I'll need the printer for next, but I know what I can do with it and I know: I'll need it again: at the latest, when a plastic part breaks somewhere, I think about whether I can print a replacement part myself ... ... continue reading

3D: direct extruder drive self printed

created: 2023-01-03 from Bernhard

I wanted to provide the extruder stepper motor with a smaller drive gear so that this brings a little more force on the filament and clogs the nozzle less easily. When using a smaller gear, the position of the direct extruder MK8 no longer fits, so I redesigned, printed and replaced the parts around the stepper motor. As material I used PETG, because PETG tolerates a bit more temperature compared to PLA. I was able to successfully test printing with temperatures up to 260┬░ with the setup. ... continue reading

created: 2022-12-27 from Bernhard

The available CAD programs with OpenSource license can't really keep up with paid products of other manufacturers, nevertheless the thought to get along without license motivates me and therefore to rely on open source software. Starting with OpenSCAD, I later ended up with FreeCAD and Blender. ... continue reading
