Here's a copy and paste of the notes from the recent class on the FSlaser 3d printer.

(fslaser.com / FSL3D)

Laser based 3d printer

Software (RetinaCreate 3D)

• Pegasus takes .STL only on usb

• Download from fslaser.com

• Leave two squares to the edge for headroom

• RIght slider shows slices

• Change shell thickness in “support options”

• Support an object for every print

• can use “automatic support system”

• manually support something over 45 degrees

• Check with a verification tool to see if there is anything that should be manually supported. Definitely support anything showing up red.

• If you move the model after all of the support is set up, then it was all go bye bye.

• Save it as a job file once all the support structure is set up

• Save job on root of the USB, the printer will not pick it up in a folder.

Resin

• 10% volumetric shrinkage with this resin.

• let it sit on a 99% IPA (isopropyl alcohol) bath for 20ish minutes.

• For precise work, print the piece at an angle.

• Two types

• water washable (?)

• clear (?)

• Similar strength to ABS

• Flexible resin isn’t ready for prime-time yet.

Curing

• Always have supports for the first few layers, they will tend to be over cured.

• May need UV box

• Avoid warping by keeping the piece on the build plate while it’s curing.

Setting the Bed

• Never remove the plastic layer, the silicone layer is necessary for the first layers to adhere.

• Vat tray holder is hinged to break suckage.

• Leave ball noses loose and slide in the tray

• bring the bed down until it makes contact with the bottom of the vat

• Lift tray at each corner to test if there is play (that will indicate if the level needs to be adjusted)

• touch circle on the screen

• hit calibrate and set the home position

• hit (test home) Itll rise and fall to show you if there are any issues.

• fill up the vat to the top if the notch MAX.

Internals

• KEEP IT DUST FREE

• Never touch the galvo mirrors.

• If you must, clean with IPA.

• Lithium grease the thread screw. Spray on finger and rub on thread.

Printing

• Disable “Pause for Refill” before lights out printing. The print will fail once the resin runs out.

• Tip: After the supports are done getting printed, open the lid and fill up resin. Once the lid is closed Pegasus will ask if you refilled the resin.
