| Résumé : |
Much as when injection molding materials were being developed 30 years ago, the current trend in additive production is toward higher melting materials and materials with improved mechanical properties. The latter can be achieved, for example, by fiber embedding. In machine technology, the developments are increasingly aimed at adapting processing times, sensor systems, and quality monitoring to the demands of high-tech companies. |

- Figure : Sample of a complex part 3D-printed from PA6
- Fig. 1 : 3D-printed parts from materialise for th ecabin interior of Airbus airplanes
- Fig. 2 : Fixture made from Antero 800NA to replace a conventionally manufactured PEEK part for mounting hydraulic parts on an airplane wing
- Fig. 3 : Carbon nanotubes embedded in plastics include conductive structures in USB demonstrators, thereby enabling an LED to glow
- Fig. 4 : Design study made from a carbon fiber-filled polyamide. The part was produced in a laser sintering process
- Fig. 5 : Roadmap for materials development at HP. The next steps will probably be toward high-performance materials, flame-retardant and hollow glass sphere-filled materials
- Fig. 6 : This model of the heart of a young girl named Jemma was created by an HP Jet Fusion 500/300 series 3D printer. The model helped surgeons prepare for a complicated heart OP
- Fig. 7 : This part made from PC with 13% carbon fiber content was melting pot and stirred by rotary motion of a spiral (transparent) and a PC with 30 % CF (black) was put in the printer manufactured from two raw materials. A simple mixture of pure PC
- Fig. 8 : Developed by Bugatti: this 8-piston monoblock brake caliper is the world's first brake caliper made by 3D printing and also the largest generatively produced titanium part. Thanks to optimized structures, a 40% weight saving was possible
- Fig. 9 : Additively produced mold insert with confor¬mal cooling chan¬nels. The mold insert is produced in layers of metal powder
- Fig. 10 : Production system from Desktop Metal. The so-called Single Pass Jetting technology is claimed to be 100 times faster than laser based systems. Market introduction is planned for 2019
- Fig. 11 : Powershot S blasting creates a homo-geneous surface quality and reduces the roughness typical of additively produced
- Fig. 12 : Schematic illustration of chemical part smoothing. The untreated part is on the left, the one on the right has gone through the smoothing process |
