3D PRINTING DESIGN RULES

Testing the design rules of our printers in Fablab-Montevideo

3D printing: testing capacities

Alejandro Ferreira, our local 3D Printing & Scanning master at Sinergia Tech gave us a complete class about 3d printing: we went from fabrication types, to the outstanding events in printing history, materials, quality, available software and printers, and lastly handling, funcionality and maintenance of machines. What a good journey, thanks Ale! Here are a few notes i took (only in spanish, sorry .. ) In order to test our FabLab best 3d Printer, the Ultimaker 2+ , Mercedes downloaded a very demanding "torture" test from Thingiverse . Once in Cura we made some configuration tests varying quality, fill and size settings in order to estimate an appropriate duration of the printing process. We arrive to a final solution ponderating quality and time, here are the parameters. Before beginning the print process we must clean the glass bed of the printer and then add some hairspray to improve the adherence of the PLA to the printer bed. Now we're done, let´s print! The printed test seems to be in good condition. We get almost all the details in the 3D model, except the top vertex of the pyramid and the cone. We compared our result with the ones tested in Fablab Barcelona. You can also check here for the entire document for better understanding on 3d-printing design rules.

TORTURE TEST

First -group- assignement: testing local machine printing performance. Not much creativity needed here: we downloaded a model from thingiverse and got the printer ready to print it.

Below both, printed test and review on printed result.

My concern was testing slenderness. I guess this is a kind of mix between two parameters.
