Head with gas mask

Materials used for printing

Materials used for post processing/painting

  • For all things black: Vallejo Model Air Black RLM22 (V71057)
  • Primer: Vallejo Surface Primer USN Light Ghost (70615)
  • Varnish: Vallejo Model Color Gloss Varnish (V70510) I did have a bit of a “problem” with this varnish though, it stayed somewhat “tacky” even weeks after being applied. It has been suggested to me to wipe it with IPA but I haven't tried that yet, so be aware that this might not be the ideal varnish.

Headshell

To reduce weight the headshell and all other components (except for the ears) were printed using LW-PLA (lightweight PLA). This pla foams up above a certain temperature, which reduces its density greatly. There is a tradeoff of course, because as the density reduces so does the strength. Although in my experience even at 50-60 % weight (compared to “solid” PLA) it's still pretty tough and flexible.

My typical post processing sequence for PLA prints is as follows. Keep in mind this is just what I do CURRENTLY, and this is an ever evolving process and I do not claim this to be the best orcorrect way to do it!

  1. Remove brims, burrs, and strings
  2. Coarse initial sanding using 240 grit paper (dry)
  3. Glue what you need to glue together, if there are multiple parts to combine
  4. Second coarse sanding using 240 grit paper (dry)
  5. Spray with filler and let it dry (spraycan)
  6. Sand with 400 grit paper (wet)
  7. Spray with filler and let it dry
  8. Leave to dry
  9. Sand with 600 grit paper (wet)
  10. Spray with filler and let it dry
  11. Sand with 800 grit paper (wet)
  12. Optional: Spray with filler and let it dry
  13. Optional: sand with 1200 grit paper (wet)
  14. Spray primer pass 1(airbrush) and let it dry
  15. Spray primer pass 2 (airbrush) and let it dry
  16. Spray colour pass 1 and let it dry
  17. Spray colour pass 2 and let it dry
  18. Optional: Spray colour pass 3 and let it dry
  19. Optional: leave to dry
  20. Spray varnish pass 1 and let it dry
  21. Spray varnish pass 2 and let it dry
  22. Optional: Spray varnish pass 3 and let it dry

You may need to repeat one or more of these steps (especially during sanding) depending on the print, and how fine of a finish you'd like.

Ears

The ears have been printed without any infill, with 2-3 outlines (need to check). They then recieved a grey primer (Vallejo, 2 layers) and then were painted black(using Vallejo air black, again 2-3 layers). Finally they recieved 2-3 layers of glossy varnish. I used an airbrush for all of the paint layers.
