DP Seals adds 3D printing to its tool room process

04 April 2013

Recent advances in polymer 3D printing materials bring dramatically increased realism to printed prototype rubber mouldings, significantly speeding the time from CAD drawing to final tooling.

For many years, DP Seals has provided a direct, high-efficiency CAD/CAM link from its clients’ engineer desktops to the in-house tool room, ensuring accurate prototype tooling in optimum time without compromising precision or quality.

By augmenting this link with 3D printing of custom seals and mouldings, the company can shorten this prototyping process and so further speed the clients’ development programmes.

“Adopting the latest 3D printing technology in our tool design department was the next logical step in speeding the process from drawing to tool for our clients,” says Andrew Piper, DP Seals’ technical director. “It is really fast and, because we use a rubber-like print medium, the client can better visualise the end result and identify potential design faults.”

For DP Seals, the catalyst to adopting this innovation is the recent availability of a range of rubber-like polymeric printing materials that exhibit many elastomeric characteristics - diverse Shore A hardness values, elongation at break, tear resistance and tensile strength.

This level of flexibility is crucial to the client’s prototyping process, allowing problems to be ironed out – such as the fit of male/female mating, or ease of cable feed-through - and make any modifications prior to final tooling.

The company's new mobile-ready, main and application specific websites are, and
