The sub-pixel micro scanning technology, the core technology of Prismlab MP series precision micro nano 3D printer, is the research result of the national key research and development plan project “micro nano structure additive manufacturing process and equipment”. This technology can greatly reduce the printing error, improve the printing efficiency by 5-10 times compared with the equipment in the same industry, and is a real scientific research tool.
This technology is based on the "micro focusing - micro scanning" technology of microlens array. Under the same precision conditions, the forming efficiency is more than 30 times higher than that of DMD chip, which solves the "neck sticking" problem of American chip; All parts and components of the equipment can be independently researched and developed by domestic anti-aging LCD, which can ensure a service life of 10 years under the condition of 7*24h non-stop printing.
Sub pixel micro scanning technology - principle
1. Spot reduction (minimum 500nm):
By using microlens array technology, the spot of surface projection is reduced to obtain sub-pixel spot
2. Spot position control:
Using piezoelectric micro vibration scanning technology to control sub-pixel spot for accurate physical arrangement
