In a new process, a metal insert is partially premolded and then overmolded using conventional technology with traditional plastics used for housings. In the premolding ptocess, conductive paths are affixed in place, and are also tightly sealed in one step. Application targets are sophisticated automotive mechatronic parts such as transmission and brake controls, sensors and plug-in connectors. A key new material is a nonreinforced copolyamide that overmolds the electrical conductive paths in electronic components, ensuring there is no contact with moisture or oil. According to a technical expert at BASF, the material’s developer, the polymer adheres very well to either metals or plastics. To compensate, other sealing methods, such a silicon adhesives or hot melts, were used. Some engineers even precoated metals to improve adhesion
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
