Plastic profiles made of 3D printing enable the individual design of cam timing belts with a high degree of flexibility. The thermoplastic polyurethane (TPU) profiles are printed directly on the timing belts and can be freely adapted to the respective application in terms of shape, size and arrangement. This allows even complex geometries for transport, positioning and feeding tasks to be implemented precisely.
This type of cam timing belt is particularly suitable for prototypes, small series and customer-specific applications. The implementation is based on
CAD data, ideally as a
STEP file and dimensioned drawing. Even without CAD data, it is possible to implement it according to a sketch, whereby the data is created in advance against calculation.
Compared to
injection-molded cams or
metal profiles made of 3D printing, the process offers a high degree of design freedom for small quantities and individual geometries.
At ROTH, we use a patented technology for the direct 3D printing of plastic profiles on timing belts (EP 3 346 160 B1 / US 10,457,003 B2 / CA 2,990,934).
