In this video I make 80+ latex covered foam purity seals. The aim is to make something robust that can withstand rough use and wear. I make few in the style of the 40k ones primarily to demonstrate one way these can be finished but I intend to make my final ones using text on fabric parchments (scrolls, ribbons, tassels?). This way they will stand the test of use at LARP events or simply being tossed about.

I got the blank seal from Thingiverse (link below) and then simply dragged jpegs into 3D builder to create little 3d emblems. Printed these on my Ender 3 v2 in ABS (standard settings, no support or raft). Attempted acetone smoothing but I think my ABS is a bit budget so didn't respond that well to the process. Moulded the prints in Silicone and pressed foam clay into them. Then I used the freezer method (kindly suggested by massiah_jones on instagram) which freezes the foam clay making removal easy and fast, you then just leave them somewhere to dry and rinse repeat. Once dry I gave them 2 coats of latex a blast with flexible clear coat and then touched up with acrylic paint and a dark wash. Then I made the parchments but only really to show the finished look. These can be finished however you like, I just wanted to share the process to make durable flexible small foam details for LARP or Cosplay.

ROUGH COST AND TIME BREAKDOWN:
3D process: 45 minutes active time, 11 hour print, costs £0.65
Moulding/Molding: 20 minutes active time, 16 hour cure time £8.00
Demould and clean up: 20 minutes active time
Foam clay casting: 10 minutes per round, 5 rounds 50 minutes total active time, 3 hours freezing 24 hours left drying with 5 minute active time to turn once. £7.00 in clay
Latex application: All in latex process took 1 hour 20 of active time for 2 front coats and 1 back coat and 16 hours drying time. Cost negligible (£0.20)
Clear cast: 15 minutes active time for 2 coats on front 1 on back, 1hr and half drying time total. (£0.40 ish)
Finising with the airbrush: took about 40 minutes, mainly because I spent 30 minutes faffing with a blockage due to user error so it's usually a very fast process. Look after your airbrush!
Dip wash: 10 minutes, 1 hour to dry (£0.05 if that)

TOTAL ACTIVE TIME ON THIS PROJECT START TO FINISH: 13 hours
TOTAL PASSIVE TIME (I was able to work on other things whilst things dried and set): 72.5 hours
TOTAL COST FOR 90 SEALS: £16.30 this would come down moving forward. The costs per 90 from now on would be £7.65 each seal costing roughly £0.9 in material costs alone.
