Repeating unit of polyphthalamide. Polyphthalamide (aka.PPA, [1] High Performance Polyamide) is a subset of thermoplastic synthetic resins in the polyamide family defined as when 55% or more moles of the carboxylic acid portion of the repeating unit in the polymer chain is composed of a combination of terephthalic (TPA) and isophthalic (IPA) acids.

3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties. [1] Filament comes in a range of diameters, most commonly 1.75 mm and 2.85 mm, [2] with the latter often being confused with the less common 3 mm. [3]
Synthetic polyamides are commonly used in textiles, automotive industry, carpets, kitchen utensils and sportswear due to their high durability and strength. The transportation manufacturing industry is the major consumer, accounting for 35% of polyamide (PA) consumption. [2]
Plain catgut Chromic catgut Polyglycolide (P.G.A.) Polydioxanone (PDS) ; Description: Adsorbable biological suture material. Plain is an adsorbable suture made by twisting together strands of purified collagen taken from bovine intestines.
The characteristics of polycarbonate compare to those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate is stronger and will hold up longer to extreme temperature. Thermally processed material is usually totally amorphous, [ 7 ] and as a result is highly transparent to visible light , with better light transmission than many kinds ...

ASA/PC (polycarbonate) blends have been prepared and are commercially available. [ 12 ] [ 13 ] In the Fused Filament Fabrication 3-D printing process, the ASA filament is used to fabricate 3-D printed parts, which above all must absorb a certain amount of impact and impact energy without breaking.
