Trumpf, Ditzingen, Germany, has introduced its new TruPrint 1000 Additive Manufacturing machine for series production to the North American market. The entry-level machine was redesigned for the manufacture of dental prostheses cobalt-chrome or titanium alloys, but is also intended for use in other medical technologies, R&D and small-series production.

“The new TruPrint machine is two times faster than its predecessor and is ideally suited for series production, especially in the dental or medical technology industry,” stated Adam Simons, Head of AM Sales & Product at Trumpf Inc. “It is one of the best choices on the market for processing titanium thanks to the machine’s inert powder cycle and very low gas consumption.”

The TruPrint 1000 features two 200-watt lasers and a multi-plate option, which allow users to run multiple builds without operator intervention by automatically exchanging the build plate. Users can stack up to four build plates on top of each other in the build cylinder, and the system prints components on them one after the other.

“The TruPrint 1000 can produce overnight or on weekends, running multiple jobs automatically without a worker having to be present,” Simons explained. “Users save a lot of time and costs, too.”

The new TruPrint 1000 only uses half of the floor space needed by previous editions and can pass easily through a standard door, allowing those in smaller production environments to have several machines running side by side to further speed up series production.

“The machine was redesigned to meet the specific needs of the dental market,” added Simons. “Using the Multilaser with a preform, up to sixty-four individual abutments can be printed in approximately one hour.”

In the Multilaser version, the machine has two lasers, both of which can process the entire build plate. The TruPrint 1000 also uses a beam expander to automatically adjust the spot diameter of the laser for the particular build job. The spot diameter is 55 or 80 micrometers, depending on the application. The wider spot allows for higher productivity, while the 55-micrometer spot can be used when special powders need higher energy density.

With an exchange kit, the build, powder and overflow cylinders can be easily changed, and the filters are accessible on the side of the machine for quick replacement. A material change, such as from cobalt-chrome to titanium, can be completed in fifteen to twenty minutes. The user can also clean the additively manufactured components and unpack the build job without opening the door, ensuring operator safety.

Simons continued, “Thanks to the primary and secondary flow, the work area remains clean even after several build jobs and the protective glass does not become contaminated. The same is true when processing tool steel, which can be prone to heavy fuming.”

If the machine’s protective glass does get dirty, the operator can remove and clean it in a few steps. The sophisticated gas flow is also said to ensure a consistent production process, as predefined laser power always reaches the powder. Thanks to the clean working environment, users can apply higher layer thicknesses, thus increasing the machine’s productivity and improving the quality of the additively manufactured components.
