Below is a collection of 3D prints that I hold on to because they represent a method I have accomplished with 3D printers.
Multi-material Print. This is a 3D printed Pokemon printed with 3 different materials on a single extruder printer. It was printed using a material management system made by Mosaic3D.316L Stainless Steel Gears. These gears were printed from 316L Ultrafuse filament. PLA Vase. Built on my home 3D printer as my first “good” part. The printer’s volume is 800mm x 800mm x 700mm. This part is in PLA because the bed is not heated yet. Bed heaters are my next project up.Glass-fiber PEEK vase. This part was made when I wanted to see the largest sized parts I could make in high temperature thermoplastics. PEEK was always the biggest bear to print, but glass fiber tends to reduce warping and help with interlayer adhesion. Not as well as carbon fiber, however. Despite some imperfections, the size of the part was an accomplishment on its own.Copper plated PLA whistle. This was a side project of mine. I applied a conductive coating to the surface of a PLA printed whistle, then electroplated using copper. Steel knives. The top knife was printed from 316L stainless steel filament and sintered by DSH technologies. The bottom was printed directly with MIM materials and sintered in house. The upfront cost of using filaments was much less, but the material cost is much higher. Conversely, using pellets to print and sinter in house was a more expensive upfront cost, but a tiny fraction of the materials cost. Also, the pellet feedstock appeared to consolidate better overall.BAAM printed part. This part has a ~0.25″ layer height and is made from carbon fiber ABS plastic pellets. ULTEM 9085 Tube Mount. This was a functional part of the SAAM HT used to mount the liquid cooling system tubes.174PH Stainless Steel Model Engine Block (green state). This part was one of the first complex parts I printed on the pellet printer that we had developed. It is in the green state, so it is brittle, but can be debound and sintered to density.
