M4A1 Rifle from Alien - Printed in PLA - 0.22 layer height

15% infill.

so.....much......sanding...... GAME OVER MAN!

Some serious sanding required if printed at 0.2 by worth the effort. There were a few moments when I was close to “game over man, game over” All joins needed filling to ensure a flush finish and roughly 3 layers of primer before adding the olive drab spray which isGolds brand of pro spray. Although you can probably still see some of the rough finish I focused on my dry brushing and used the rough finish as part of the design. Have fun all you won’t regret it.

So much sanding and filler primer ;) I wasn't the only one to find the tabs for alignment didn't fit - I had to either grind down or cut off the tabs, or grind out the hole. Really slowed the process down. I also joined a few pieces in Tinkercad and changed print alignment. Given that I printed this over a long period of time, it's probably a mix of ABS, PLA and PETG. I painted it while the gun was in 3 main pieces - the main gun (with stock, grip, magwell, shroud), with the top barrel and launcher separate parts from the main body. This is so I could get into the nooks and crannies. I then glued the pieces together afterwards (in Tinkercad I'd made a hole for the top barrel to slot into). Painted almost entirely with an airbrush. After an undercoat of flat black; * Satin black for pump grip * Mix of flat black and gun metal for the grip, barrel, top of Thompson and stock * Olive drab for the shroud, counter and mag well * Gloss black and red plus clear gloss for the counter

Was able to merge a few parts for less glueing. ABS at 255C with a bed temp of 105C. Nice model i plan to mod the crap out of it on my next try.

Here is my copy of this design. Nice work! Thank you.
