Stereolithography Puns

In this study, porphyrinic zirconium (Zr) MOFs were investigated as heterogeneous photocatalysts for photoinduced electron transfer–reversible addition‐fragmentation chain transfer (PET‐RAFT) polymerization of various monomers under a broad range of wavelengths, producing polymers with high monomer conversions, narrow molecular weight distributions, low dispersity and good chain‐end fidelity. Screening of various porphyrinic Zr‐MOFs (Zn) demonstrated that MOF‐525 (Zn) with the smallest size had the best photocatalytic activity in PET‐RAFT polymerization, due to the enhanced dispersion and light penetration. Oxygen tolerance and temporal control were also demonstrated during MOF catalyzed PET‐RAFT. Results suggested that the polymerization rates were significantly affected by changing the size and surface area of MOFs, and the heterogeneous MOF photocatalysts could be easily separated and recycled for up to five independent PET‐RAFT polymerizations without an obvious decrease in efficiency. Finally, the MOF photocatalysts were utilized to create three‐dimensional polymeric objects with high resolution via visible light mediated stereolithography in an open‐air environment.

What do you guys think about stereolithography for printing out a terrax pattern, would it look decent? No i dont need a morality lecture that thing is stupidly expensive

One common use for STL files is 3D scanning of physical objects. This library uses a concurrent algorithm to read in the data. For large (100+ MB) STL files, this can make a big difference.

I made a benchmark where a user can see the performance increase as the core count increases.

I used this at work to read in a Solid and then manipulate the triangles from there to make something else. Hopefully someone else can get some use out of this!
