formlabs Form 2

Form 2 printer is a stereolithography (SLA) resin curing based 3D printer.

There are a few differences and similarities to SLA 3D printing when compared to the typical FDM printing

Simplistically, a 405nm violet laser cures resin layer by layer until a 3-dimensional part is produced. A video explaining further can be found here.

This tutorial will teach only the basics of resin printing to get you started and is not an all-inclusive guide to resin printing.

It is assumed that the user has a 3D model that fits within the Form 2 build volume and is a valid part file

log onto the BME Laptop in Fab lab using credentials provided at the top of the screen

Click on PreForm slicer icon as seen in image

Open 3d file within PreForm with a STL/OBJ/3MF file format

Roughly verify scaling of part by visually identifying size of object on the screen. If needed, scale your part

Orient your part so as to avoid cupping or other common issues by using the orientation icon

Autogenerate supports . Supports are needed in areas that would otherwise not be connected to the build plate or need extra support in order to print properly

Verify printer is connected to PreForm slicer. The printer is named "ClassyNarwhal"

Verify the material type you intend to print with. The default material is the "Clear V4"

If another resin type is desired than what is currently in the printer, ask the Lab Director for assistance in changing the resin tank and resin cartridge

Transfer file to printer by clicking the orange print icon on the left of the screen

Before touching machine, put on PPE including safety glasses and gloves

Find the file that you put on the printer via home screen

Tap Print Now. This will not immediately start the print. It will only begin the process and prompt you on next steps

The screen will now show two items to verify before printing

Open cartridge vent as seen on the image to allow the printer to autofill with resin

Verify that the build platform is securely on the printer as seen in image

Press the push button to start the print

After a print is finished, it needs to be washed in Isopropyl alcohol.

Before transferring the part to the Form Wash, put on gloves

Please be considerate and mindful by cleaning up any resin that drips onto the floor or workspace.

A great video explaining washing of your part can be found here.

The specific settings for length and quantity of washes can be found here.

FormLabs provides cure times and temperatures in this chart.

Currently we do not have the FormLabs cure station but alternatively use an Elegoo Mercury Plus to cure parts

To use the cure station follow these steps:

remove lid

place washed part on stage

replace lid

add cure time according to FormLabs chart (15-30 min for clear)

start curing procedure by pushing play
