Assignments
- Test the design rules for your 3D printer(s).
- Document your work on the group work page and reflect on your individual page what you learned about characteristics of your printer(s).
Individual apport
- Ernesto: My contribution to the group work was to test the design rules of the Sonic Mighty 8K Phrozen SLA (Stereolithography) 3D Printer.
- Jorge: As the person in charge of FDM 3D printing, I conducted tests using both the Bambulab X1C and custom Vzbot235AWD 3D printers.
- Marcela: I was responsible for documenting and summarizing the machine parameters.
Process
For the 3D printing week, we used a model from Printables to compare the two printing technologies available in the lab at that time: FDM (Bambu Lab) and SLA (Phrozen). We defined the FDM printing parameters and printed the same Voronoi dragon model to compare the results.
The main difference between the results is the surface finish. The FDM print, even with the smallest layer height, still shows traces of the layers. Due to the scale, the areas that had contact with the supports did not suffer significant damage. In contrast, the SLA print requires more post-processing time to achieve the final piece. Additionally, the SLA process is considerably messier compared to FDM.
