As someone said in another thread , its a bit like the days of 8bit micros for micro manufacturing /3d printing.

Wondering if Fused Deposition Modelling, FDM, melted plastic filament may be the betamax against new crop of photosensitive resin printers VHS , or is that the VIC20`s against the Spectrums ;-)

Formlabs is kinda traditional SLA in that it uses a scanning laser

Few appearing using DLP video projector:

UV cured modeling

B9Creator - A High Resolution 3D Printer by Michael Joyce — Kickstarter

3 D L P rint » New Video – 4 rings

3d printer reduced to the essentials:

Sedgwick 3D DLP. 3D DLP Printer Kit

Mechanics appear to be reduced to an accurate Z axis....

Interesting times

Cheers
