• Time spent editing Cad models and setting up prints: 1hr
• Average machinist pay per hour: $19.35

Materials: $0.62

PLA: $0.61

Clear Resin:

1L of Formlabs Clear resin is $149

Print volume was 22.21mm^3

1L= 1,000,000 mm^3

1L* 22.21mm^3/1,000,000mm^3 = .00002221

Process:

I chose an impossible box from bkidmose at url: https://www.thingiverse.com/thing:2914215

Printing it was pretty easy because I did not have to worry about gaps between moving parts getting too small when I scaled my part down. In the end I scaled the part to a 22x22x22mm cube. I printed 4 using the Prusa FDM printers. I then printed and treated two more using the SLA Form Labs printer.

The hardest part of this assignment was removing all the supports from the prints and these supports left imperfections in the surfaces of my prints. In the future I want to try using a dissolvable support material to circumvent this issue.
