===== About =====

The Form4 Printer is located in the Innovation Workshop on the countertop in 3430. Compared to the Form3's, the Form4 prints 2-5x faster and allow for increased build volume, as well as more features which you can read about here: [[https://formlabs.com/compare/form-4-vs-form-3/?srsltid=AfmBOopOKqqxsKkFMt-5jGpYTqhyxaCP7Ae-af-HAoBKvL-oa4EI0gQd|Form4 improvements]]

The FormLabs printers are liquid resin stereolithographic 3D printers capable of producing high resolution accurate models out of a variety of materials. Liquid resin printers use a bath of reactive resin which is precisely cured using specific wavelengths of light. This printer is particularly well suited for thin, high aspect ratio features and models requiring great surface accuracy. 

Based on the material and application, some prints will benefit from post process UV curing to strengthen and harden the finished part. See part curing documentation in UV FormCure reference documentation. 

The Form4 uses its own resin cartridges and build platforms, that are not cross compatible with the Form3 printers. The same wash and cure as used with the Form3 printers are used for post processing with the Form4.

===== Safety Concerns =====

The resin used in the FormLabs 3D printers is considered hazardous. Gloves are to be warn when replacing or removing build plates, build tanks, and resin cartridges. Refer to SDS for disposal and health hazards.
