Training Checklist:
- Safety: personal protective equipment, avoid eye contact with laser, avoid contaminating areas with resin
- Job Setup
- On the computer: PreForm software, file orientation, adjusting supports, record in FBS, selected material and version match the resin type loaded in the desired printer
- Printer: confirm print, avoid any spills
- Using the Form Wash: transport part and build platform, wash and allow time for IPA to evaporate
- Using the Form Cure: release part from build platform, adjust curing settings depending on resin
- Post Processing: break support material, abrasives to remove marks left by touchprints
- Replacing an empty resin cartridge with a full one of the same type
- Remove and replace cartridges
- Avoid spills
- Mark off new build tanks when new resin cartridge is put into rotation
- Switching a printer from one type of resin to another
- Remove build platform, resin cartridge, and resin tank
- Cover resin tank
- Insert resin tank, lock wiper blade, insert resin cartridge, replace build platform
- Mark off new build tanks when new resin cartridge is put into rotation
- Maintenance: clean resin tank interior, filter resin, cleaning tank window
Overview:
- This training provides an introduction to using and operating the FormLabs SLA 3D printers including:
- File Types
- Software
- PreForm 3D
- Safety
- PPE for working with resin
- Understanding transportation of uncured resin
- Printer Use
- Post Processing
- Form Wash
- Form Cure
- Printer Maintenance
- Switching Resin
- Cleaning Build Tanks
- Troubleshooting
- The Form 2/3 is a 3D printer that uses SLA (stereolithography) to make a part. In SLA, a laser beam is directed into a tank of photoreactive resin, which hardens to form a layer of the part. The first layer adheres to the build platform, and each following layer adheres to the previous one. The finished part will be suspended upside-down above the resin tank. It has a build volume of 145 × 145 × 175 mm (5.7 × 5.7 × 6.9 in).
- The Form Wash is an automated washer that bathes the printed part in IPA (isopropyl alcohol) to wash off residual resin.
- The Form Cure is a chamber that exposes a printed part to UV light to finish the curing process. This is referred to as ‘post-curing.’
- Remember to enter job information into FBS!
Safety
- Nitrile or neoprene gloves (not latex), safety glasses, and a lab coat must be worn when working with liquid resin printers. Safety glasses and a lab coat are required for working around IPA (isopropyl alcohol) when the Form Wash is open.
- Avoid eye contact with laser. Do not remove the front or back panels of the printer.
- Care must be taken to prevent contaminating other areas with liquid resin - use containers to transport build platforms or parts that still have liquid resin on them.
- Dispose of resin contaminated gloves and other objects in the yellow hazardous waste bin in 2442.
Job Setup
On The Computer:
- On the desktop computer near the Form 2/3 printers, open the PreForm software from the start menu.
- To start a new print, click File > New
- File > Open, select the .STL or .OBJ file you want to print.
- Set the scale, orientation, supports, and layout.
- Formlabs recommends orienting flat surfaces at an incline of at least 20°.
