Zeiss’ has announced a new additive manufacturing solution service, ParAM (parameter for additive manufacturing) aimed at producing defect-free parts. Print parameters enable printing with a new material, adapting to change in powder characteristics and increasing print speed by increasing layer thickness to even placement of parts on the build plate.

Zeiss and (ORNL) are developing a novel, fully automated solution to comprehensively evaluate a set of parameters in less than 12 hours.

“Our goal is for the user to start with a design of experiments, print coupons and evaluate best print parameters from the design of experiments plan in the same day, so they are ready to print parts the next morning,” says Pradeep Bhattad, product manager for Zeiss ParAM, a rapid parameter qualification solution.

According to Ryan Dehoff, section head for secure and digital manufacturing at ORNL, “Currently only a handful of alloys are qualified for printing, and the majority of these are used in conventional manufacturing. However, there is tremendous benefit in developing and qualifying novel alloys specifically designed for additive manufacturing. The current challenge is the qualification process, and technologies that can accelerate the development of new materials are critical.”

According to Zeiss, the ParAM’s test design and evaluation workflow makes it a versatile solution for multiple applications. Examples include evaluating parameters to print defect-free parts with a change in powder quality or a degree of recycling, developing print parameters for thicker powder layers, qualifying a build envelope, evaluating or compensating for a laser performance in multi-laser systems and creating a parameter to print deformation-free parts. Zeiss says parameter optimizations can help reduce the build failure rate and make additive manufacturing processes reliable, while reducing the cost per part.
