Glock G17 gen 3

remember this is not airsoft, make no mistake

3.1 Print Settings

For a light duty/workable frames:

Material: eSun PLA+

Print Temp: 235 C

Bed Temp: 60 C

Bed Prep: Wipe clean, apply a thick layer of Elmer's glue stick. Kapton tape is recommended since this frame will really stick to the bed tight if you use the STL with the raft.

Infill: 100%, Rectilinear Fill

Enclosure: None

Orientation: not super critical but using the STL with the raft will result in far less warp. Warp is the enemy of this project.

Supports: full, hexagonal infill, sheathing on infill optional but recommended if your slicer supports it.

Remember that PLA will not stand up to hot environments. While the gun itself won't hold enough heat to hurt the frame (I dumped 50 rounds as quick as I could load them without issue), having this frame sit in a hot car would damage it.

For a heavy duty/durable frames:

Material: Zytel or Glass filled Zytel

Print Temp: 287 C

Bed Temp: 100 C

Bed Prep: Wipe clean, apply a thick layer of Elmer's glue stick. Kapton tape is recommended since this frame will really stick to the bed tight if you use the STL with the raft.

Infill: 100%, Rectilinear Fill

Enclosure: None needed, but it will not hurt if you use one.

Orientation: not super critical but using the STL with the raft will result in far less warp. Warp is the enemy of this project.

it was many hours of work!

materials

3d printer: Prusa MK3S

extruder nozzle: Ev3DM Tungsten Nozzle 1.75mm x 0.40m calipers (for slicer filament measurement)

printer filament: eSun PLA+ (including light blue, yellow, green, red)

print settings

slicing:

slicer: slic3r Prusa Edition v2.1.0

filament thickness as measured by caliper: ~1.70mm to 1.73 (depending on color/roll)

temp: 220 (225 & 230 also seem to work well)

resolution: 0.15mm (performed some at 0.10mm with some nicer detail but longer print time)

orientation: magwell up

 with magwell down: significantly increases filament usage and print time, as well as surface (rather than interior) support artifacts

infill: 100%

supports:

 z-contact: 0.20mm (0.15mm also works but it's more difficult to remove supports)


 pattern: rectilinear (didn't see a huge difference vs. honeycomb when not using sheaths)


 sheath: no (tried both ways, didn't seem to get a lot of help from sheath and it makes support removal much more difficult)
