I looked around for a long time at printers and was tempted by the Form2. But I chose a top down type. To me the advantages include:
- No build tray to replace, scratch, cloud up or clean.
- DLP projection is straight down so the 3D pixels, the voxels remain cubic, whereas as a Laser beam will be angled from source and need software compensation to say reproduce a perfect square or oval at the edge of a build plate. Shine a torch on a wall at an angle to see what I mean
- 30 micron (0.0011811 inch) square resolution by 5 micron thickness adjusatbility
- Extremely high build quality.
- Amazing resolution on hard resins and still very good with castable.
- Very good value compared with the high end names and arguably better built with better components.
- Laser focus on every single exposure!
- Build time for a tray of rings at 30 micron xy will take about 3 hours
- Manufacturers castable resin is just out and fairly priced.
- You can buy 30x30 up to 70x70 xy micron resolution models, the latter have bigger build plates
- Uses laser scanner to indicate required perfect horizontal alignment.
- Smaller build plate at the highest resolution models, but that is common to most printers
- xy resolution is fixed and hence so is build plate size
- New company
4 Tank needs much more resin, but it lasts well if portable tank is kept in the dark when out of use
- Noisy but very strong motors.
I am not an agent for the manufacturer in China. Whatever your thoughts were on Chinese QA, this is made to Mercedes quality specs and the models are very high resolution. Have a look.
