Additive Manufacturing

From our state of the art Technology Centre, housing a number of Renishaw Laser Powder Bed Fusion Additive Manufacturing machines, we offer a range of Additive Manufacturing services:

Build to print: Whether a simple part or one with significant internal complexity HiETA offers build to print services that benefit from our expertise in build set-up, data handling, optimised process parameters. Parts of up to 250 mm x 250 mm x 330 mm can be built in a single piece or larger assemblies realised by welding of parts.

Materials selection and process parameter development: HiETA routinely processes AlSi10Mg, Ti6Al4V, 316 Stainless Steel, Inconel 625 and Inconel 718. For thin wall applications, we have developed proprietary process parameters for AlSi10Mg, Inconel 625 and Inconel 718. Recently we have developed thin-wall parameters for CM247LC which facilitates improvements in high-temperature performance and we are working with customers to realise their parts with these parameters. A wealth of experience has been gained in understanding the suitability and/or limitations for materials in particular applications where various manufacturing process steps are employed. We have learned that changes in one process step can affect the behaviour of a part in another process step. An example is changes to process parameters can affect the dimensional behaviour in subsequent age-hardening heat treatments. Currently, we’re taking things further via the use of Deep Learning, in collaboration with the University of Sheffield, to generate models of process chain behaviours so that optimal parameters can be selected, and part behaviour predicted.

Process parameter development: We have developed specific processes for the development of process parameters for bulk material and thin walls. If you are interested in developing process parameters for a specific material, we would be happy to assist so please contact us.

SLM Process: We have established parameters and processes for AM250 Plus-Pac, Ren AM500M, and Ren AM500Q machines. We are always first or early adopters of new additive technologies and design parts to build efficiently on future generations of AM machine.

Powder removal: We have established the local limits for powder removal over a range of fine-feature geometries. These are then combined with strategies for the global removal of powder for large components with tortuous internal architectures. In collaboration with Renishaw and the University of Sheffield, we are currently working on developing automated powder removal hardware and process models using Deep Learning, to ensure rapid and reliable outcomes. Furthermore, we are currently developing methods for tracking and confirming the successful removal of powder from devices.

These comprehensive services allow customers to access the same enabling capabilities that allow HiETA to create its range of cutting-edge proprietary products. Please contact us to discuss your requirements.
