We are planning to introduce a top down SLA 3D printer.
The core part is a closed-loop resin level control system to eliminate liquid surface tension error and control liquid level accuracy ± 0.005mm, and a vaccumcoating system for accurate resin coating.
Scanning method: Galvoscan
Forming direction: TOP-DOWN
Spot diameter: 0.05-0.10mm
Print size: 130 * 130 * 180mm
Layer thickness: 0.03-0.15mm
Pros: very stable printing with 99% success rate; no VAT needed; support all types of resins; easy to exand to large print area.
Cons: a little slow since each wiper coating takes 5-8s; require a lot of resins to start (>3L)
Any thoughts and suggestions?
