Recently, foreign media reported that the world's leading petrochemical company Saudi Basic Industries (SABIC) launched 15 kinds of new 3D printing materials. Seven of them are FDM wire and eight are for large 3D printing.
First look at the 7 FDM wires - the most eye-catching one is the LEXAN EXL AMHI240F. It is developed by SABIC based on its existing LEXAN EXL polycarbonate (PC). The main advantages are high strength, high toughness and good low temperature ductility. Currently, it provides 1.79±0.05 mm wire diameter, but only black is available. It is worth mentioning that although it is optimized for Stratasys' Fortus printers, it can also be used with other brands of printers.
The other six FDM wires are also developed by SABIC based on its existing materials (polyetherimide PEI resin, CYCOLAC ABS resin and PC resin). They are also optimized for Stratasys' Fortus printers, but only in Europe.
Let's look at eight other materials for large-size 3D printing – they are also developed by SABIC based on their existing four amorphous resins (ABS, PPE, PC and PEI), but by adding carbon fiber and fiberglass. Enhanced, so the low temperature fluidity is better, less deformable under constant pressure, lower than the shrinkage rate of crystalline resin, the application target is mold, aerospace, automotive, defense and other industries.
It is worth mentioning that in order to prove the performance of these materials, SABIC also specially used them to print a part of the yacht hull. It consists of an outer casing and an inner bracket, the former being printed with carbon fiber reinforced PPE and the latter printed with carbon fiber reinforced PEI.
The good news is that SABIC said they will continue to introduce more 3D printed materials, including polycarbonate with SLS (selective laser sintering) technology (finished density can exceed 96%); highly biocompatible polycarbonate and PEI Wire, and EXTEM thermoplastic polyimide wire.
