Scape Technologies, Danish Technological Institute, and AMT joined in a new EUROSTARS Project: Just in Time 3D Printing Production - Fully Automated Solution in One System. 3D printing is a digital manufacturing technology, meaning that a large part of the production process is managed online. However, finishing the printed components still has some manual process steps.
The Danish company Scape Technologies, Danish Technological Institute and the UKcompany AMTwill collaborate in the field and try to automate these in a new EU-supported project. The Process of Additive Manufacturing for Creating 3D Objects: Additive manufacturing is the process of creating a 3D object by building it one layer at a time and it is using computer-aided-design (CAD) software or 3D object scanners to direct hardware to deposit material, layer upon layer, in precise geometric shapes. As its name implies, additive manufacturing adds material to create an object.
Although the terms "3D printing" and "rapid prototyping" are casually used to discuss additive manufacturing, each process is a subset of additive manufacturing. Currently the industry uses post-processing methods that are labour intensive, dusty, energy-inefficient and environment-polluting. The latter is especially problematic as current smoothing methods produce micro-fibre plastic polluted water as a by-product.
These are mechanical-contact based methods that remove material from the parts, resulting in loss of accuracy, fine features and degradation of part properties while leaving surfaces porous and non-sealed. As a result, opportunities abound for automating the complete process in one system. Industrial 3D Printing Production, Handling and Finishing Done in One Fully Automated System: Over the past years, the Danish Technological Institute (DTI) in Aarhus, Denmark has established a complete setup for industrial 3D printing production in both metal and plastic.
This setup includes both the digital processes that precede the printing, the 3D printing process itself and the finishing steps that finalize the printed parts. Precisely the finishing of the printed parts is something that primarily requires manual handling. Now, DTI will try to automate these processes in a new EU-supported project called DMS Nextgen.
The project will develop a system that can take the entire 3D printed build job immediately after the printing process and do all the finishing, i.e. cooling and unpacking, blasting the parts and finally sealing the surface. For this system, the plan is to use a conveyor bay and robot(s) to move the parts between the various process steps. The project is done in collaboration with the Danish software automation company Scape Technologies, who is a specialist in robotic automated material handling - known as bin-picking.
In this project, Scape Technologies will provide visual recognition, gripping techniques, and robot path planning development to transport the 3D printed objects between the modules of the de-powdering machine, the smoothing machine and the final stage of object inspection and sorting. The UK - Sheffield based company Additive Manufacturing Technologies (AMT) will make equipment for post-processing of 3D printed parts. At the end of the project, the entire system will be integrated, and the demo system developed in the project will subsequently be placed at the DTI.
About DMS Nextgen Project: DMS Nextgen is a Eurostars project with a total budget of just under EUR 1.1 million. Eurostars is part of the Eureka network which is co-funded by the European Union through Horizon Europe- In Denmark, the project is funded by the Danish Innovation Fund. The project runs from January 2024 to September 2025.
The project partners are the Danish Technological Institute, AMT, and Scape Technologies A/S.
