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.
