3D printing materials solutions for the automotive industry
Polymaker showed the Belgian motorcycle brand Sarolea electric motorcycle-N60. This model uses 3D printing technology from the early development, to the production stage, and then to the after-market stage. Polymaker's multi-material motorcycle case cover is prototyped using PolyMax ™ PETG material, which is not only very good The mechanical properties are also very easy to post-process.
Volkswagen and HP
According to Dr. Martin Goede, Volkswagen ’s head of technology planning and development, Volkswagen 's vision for industrialization through additive manufacturing has quickly become a reality through HP Metal Jet, which has changed the automotive industry, HP 's innovation pace and advanced technology capabilities Exceeded expectations.
Good workability, low density, good corrosion resistance, good thermal performance, low weight. Titanium alloy has high strength and low density, good mechanical properties, and good toughness and corrosion resistance. In addition, the titanium alloy has poor processability and is difficult to cut, and it is very easy to absorb impurities such as hydrogen, nitrogen, nitrogen and carbon during hot working.
HP nylon PA12 is a kind of material that has very high strength and good heat resistance. HP has accumulated in the printing industry for a long time, which makes the multi-jet melt 3D printing technology using HP patented technology very suitable for small batch production. The polyamide PA12 molecular backbone contains a large number of polar amide groups, which causes a strong force between polyamide molecules and can form hydrogen bonds(the greater the density of hydrogen bonds, the better the mechanical strength, the more carbon atoms, the worse the strength), At the same time, the polyamide PA12 molecules are arranged neatly and crystalline; The polyamide PA12 molecular main chain section also contains methylene, which makes the polyamide PA12 flexible and can affect the polyamide PA12 melting point and vitrification temperature.
Good toughness, high hardness, production of hard functional components, production of high-quality components at very low unit cost, materials imported from the United States, with FDM certification (accessible food-grade materials). PA12GB and PA12 belong to engineering plastics. PA12GB has higher mechanical properties, dimensional stability, heat resistance and aging resistance.
