Most 3D CAD Software can generate STL files from parts or bodies, in SOLIDWORKS this is done by opening a part then clicking [File]->[Save As] then choosing STL from the dropdown
Those stl files can be imported into Orca by pressing the [File]->[Import]->[Import 3MF/STL/STEP....] or by pressing [Ctrl+I]
FDM 3D printing produces anisotropic (non-homogenous) parts, so both print time, part quality, and part strength is highly depended on which direction the part is printed in. ALL3DP provides a basic explanation at this link, for questions about your specific prints please reach out to any of the staff engineers.
In Orca parts can be moved/rotated using the toolbar on the top of the screen, the "Lay flat on Face" tool (hotkey F) is particular effective
If you correctly completed the first time setup, you should have 2 "User preset" printers accessible, K1SE or Hi, these correspond to the two types of printers available in the lab, the K1SE are faster, but slightly less accurate and have a smaller max part size than the Hi, if your slicers settings don't match your printer, your prints will likely not start.
Open the profile dropdown and choose either:
Creality Hi 0.4 nozzle PPL_R#
Creality K1 SE 0.4 nozzle_PPL_R#
All different brands of filament require slightly different settings to account for many factors, including thermal expansion and retraction, choosing the wrong material settings will result in significant size errors, and/or completely failed prints.
Open the material dropdown and choose:
Overture Generic PLA..._PPL_R#
Process settings include many variables that may be relevant for your design including infill %, wall and floor layer counts ect. The defaults in the PPL_R# configuration are a good starting point to work from, however deviating may negatively effect part tolerances
Open the process dropdown and choose:
0.20mm Standard...._PPL_R#
