The Positron-LT is a printer made for everyone, especially hobbyists and professionals who don't want to or can't use machined parts. This printer is a RepRap version based on the innovative Positron V3 formfactor and motion-system which was created by KRALYN.
Although the printer is printed, it can still be folded and thus still fits into a filament box. Thus, there are no disadvantages compared to the original, it may even have some improvements
Note: This project is a work in progress! The primary design is ready, updates and changes will be made continuously.
LT stands for LighT Since the printer is made of printed parts instead of machined parts, it is lighter than the original Positron V3.
- Lighter to source
- Lighter to build
- Lighter to transport
- No Machined Part
- All mechanical parts can be sourced on websites like AliExpress, Amazon or your local hardware store.
- Much less parts to assemble than the V3
- Integrated PSU (power supply unit) with 200W
- 3mm GT2 timing belt on XY (cheaper and easier to source as the original Synchromesh wire)
- The base chassis is made of 10x10 Makerbeam extrusions and other Makerbeam parts. All other structural parts can be printed!
- Simplified Z axis by using a leadscrew. Easy to assemble by folding up
- Improved toolhead cooling
- could be used with larger XY Stepper motors up to 26mm
- Max Print Speed: 250mm/s (under investigation)
- Max Travel Speed: 350mm/s (under investigation)
- Acceleration: 9800mm/s^2 (under investigation)
- Build Volume: 180x180x180mm
- Weight: 2300-2500g (with integrated PSU)
- Hotend max temp: 250C
- Build Plate Max temp: 80-100C
- Power supply: 24V; 200W
- Footprint: ~200mmx200mm
RepRap means that most parts of the printer can be printed and nothing needs to be machined. Only basic tools like a drill or a saw are needed. All other parts are readily available and can be bought online or might even be available in a hardware store.
