TPU safe for inside the body? : r/3Dprinting - Reddit
2020年12月31日 · TPU as such encompasses a wide range of thermoplastic polyurethane filaments with who knows what additives and an undefined quality control process. I have found that TPU, printed right, has amazing layer bonding and the resulting prints are pretty much water tight. This is a print I did to make a cleaning widget for a microwave oven bacon tray ...
So I got vampire fangs, but the dentist told me I’d knock ... - Reddit
2022年2月15日 · Finished Invisalign Treatment! My face and jaw changed, lost weight because I got too lazy to take out of my trays to eat. I also have botox in my masseters for tmj. I've consulted with 5 dentists about composite bonding because I love the look of veneers but all of them have turned me away...
Anyone have experience with Bakelite? : r/manufacturing - Reddit
2021年7月13日 · I've used bakelite when mounting metallurgical samples. It seems like it is still the go to material in that use case because it has to be able to stand up to the surface preparation process. Because it is a thermoset you cannot melt it after its initial melting and forming, so this pretty much eliminates every thermoplastic bonding technique.

Materials question (Polycarboxylate Cement) : r/Dentistry - Reddit
2021年6月21日 · I found a biomaterials paper ("Poly(acrylic acid) as an adhesion promoter for UV-assisted thermoplastic bonding: Application for the in vitro construction of human blood vessels" (Le et al. 2021)) that discusses covalent bonding between PMMA and polyacrylic acid via UV irradiation to generate free radicals in the polymer backbones.
Thermosets vs Thermoplastics : r/materials - Reddit
2019年5月23日 · Reply. Share. Linq182. • 5 yr. ago. Thermosets have molecular functionality => 2. This allows massive amounts of branching upon curing as they have at least two reaction sites to form covalent bonds and entangle. Thermoplastic have functionality less than two. They tend to be more linear and rely on secondary bonds.
Soccer ball bladder material? : r/bootroom - Reddit
Although they have an additive with latex that makes air loss roughly the same as butyl Thermoplastic bonding latex is tricky because latex melts easier.so they are usually hand sewn or the thermal bonded latex balls lose shape quicker, like a year or so. The balls I had made were two types of bladder. Both thermoal bonded.
Thermoset vs thermoplastic, and Bakelite : r/askscience - Reddit
2011年11月17日 · It has a great deal to do with the physical structure of the polymer chains. Bakelite doen't carry with it the same interwrapped, loosely bonded chains found in PE's and PP's. In fact its intermoleculare bonds are quite rigid. Generally speaking, PP and PE chains only experience weak hydrogen bonding between chains.
Is this primer + paint okay for resin prints? : r/resinprinting - Reddit
2023年7月26日 · Yes. I use the straight version version of this (just primer, not paint + primer) on both plastic and resin minis. The 2X line has good coverage that won’t obscure details. CharIieKitsune. OP • 8 mo. ago. Thank you everyone for the help can’t wait to get painting!
