5.1 Operational environment
The operating temperature for the Form4B is 18–28 °C (64–82 °F), with low ambient humidity.
For optimal printing, do not exceed this range.
5.2 Designing for SLA
A successful 3D print starts with a well-designed model. Follow these best practices to optimize
designs and reduce print failures. For detailed guidance and visual assistance, visit support.

5.2.2 Feature design guidelines
Consult Design specifications for 3D models (Form4 generation) for a list of the minimum
feature requirements you can expect from Form4 generation printers.
5.3 Setting up a print
Form4B print jobs can be set up using PreForm, Formlabs’ print preparation software. To start,
open OBJ, STL, or 3MF files in PreForm, orient and layout multiple models into a complete
build, then upload the print job to the printer. For detailed guidance and visual assistance,
