By substituting ethylene glycol monomers in the structure of PET, the melting point of copolyesters is reduced, the glass transition temperature is increased, and crystallinity is decreased, resulting in PETG’s exceptionally high transparency.
PETG is a good comparison to materials like PET mentioned earlier and TPU, which is an abbreviation for thermoplastic polyurethane. PET has a higher working temperature than PETG and can stay rigid. Where it can’t compare with PETG, however, is in shock resistance, high heat, impact resistan...

PETG As the name suggests, this plastic is related to the polyethylene terephthalate of water and soda bottles but modified with glycol, hence the added “G.” It has high strength and flexibility, and when compared to the more widely used PLA, it has good temperature resistance. ...
Is PCTG a good alternative to PETG? Yes. PCTG stands for polycyclohexylenedimethylene terephthalate—no that’s not a typo. It offers higher bonds, tensile strength, and clarity and can even print matte or gloss depending on the temperature of the extruder. Talking of temperatures, PCTG requir...
Biodegradation times are heavily influenced by temperature, humidity, microbial activity, pH levels, and aerobic conditions. What Should You Do With Scrap PLA Filament? Scrap filament can be composted at an industrial facility Since PLA is a bio-based and biodegradable polymer, one might assume ...
Ceramic:Ceramics have properties that can withstand extreme pressure and temperature without warping or breaking. It’s less likely to get corroded and doesn’t easily wear away thus giving it an edge over metals and plastics. They are popular for high-precision works and provide smooth, glossy ...
A common 3D printing filament for years, polylactic acid (PLA) is the go-to choice for many applications thanks to its low cost and ease of use. A great low-temperature selection, PLA filament is environmentally friendly. It’s also derived from food crops like sugarcane and corn. It can...
There are various methods for preparing Magnesium chloride hexahydrate, with the most common one being the reaction between magnesium and hydrochloric acid. The reaction equation is Mg + 2HCl → MgCl2 + H2. It is important to control the reaction temperature and time during the preparation process...
Machined Aluminum: A temperature-controlled mold machined from a block of aluminum is clearly the superior alternative for quality pressure forming. Tolerances can be held to industry standards, and plates can often be milled and laid up with .005-inch vacuum openings along a detail area to evacu...
