Hello once again!! Now that we are done with our 2D processes, we have moved on to the magical world of 3D printing. For this assignment, we were tasked to make an “impossible object”. The object I chose for this was the Customizable Hinged Polyhedra by mathgrrl on Thingiverse.

My first attempt involved using the FDM printers, which worked out very well. I was able to create 3 of the hinged octahedrals using this and they came out extremely successfully! They didn’t work out on the first attempt: I had to resize and adjust some settings to get it perfect, but this was not too much of a struggle for me.

The hard part was when it came to using SLA. Unfortunately, SLA doesn’t work too well when it comes to hinges, so my part would come out but when I would attempt to bend the hinges it would snap apart.

So, I was able to successfully make my 3 FDM prints, but failed on my two SLA prints.

Cost Estimate:

According to 3DPrinterOS, each of my FDM prints costed $0.15, making that a total of $0.45. This assignment was not super time consuming on my part, I maybe spent a total of 2 hours actually in the OEDK figuring out and printing my parts, so saying I’m working for $10 an hour, that would be $20 of labor. According to some online sources, SLA printing costs 2.6 times FDM printing, so for my 2 prints, if they were successful, they would have costed $0.39 each, making a total of $0.78 for the SLA prints. Summing all of this together, I get $21.23.
