Additive Manufacturing Labs

Several of the additive manufacturing printers in the AM Lab are built by researchers at DTU Construct in order to achieve full control over all the parameters involved in the AM-processes.

The lab is equipped with the following state-of-the-art facilities:

Photopolymer based systems for materials and process research:

• AMANDA: a custom-built open architecture VPP system for producing high-resolution (less than 10 micrometer) photopolymer, ceramic, and metal components.
• Stratasys J35 3D printer: multijet material polymer 3D printer to fabricate multimaterial structures
• A series of commercial VPP printers, including Elegoo, Phrozen, and Anycubic
• An automated post-process setup including a robot arm and a gantry setup for automated build-plate removal 
• 3D ice litography: electron beam processing of organic ice for submicrometer 3D printing

Laser Powder Bed Fusion

• LOOP1: The first custom-built multi-material LPBF research platform for innovative materials research
• LOOP2: The second custom-built LPBF system is a single-material production-grade platform for application and material studies
• OPAL: A custom–built polymer laser powder bed fusion system with advanced thermal control and monitoring is used for polymer and ceramics research.

Binder Jetting facilities

• Exone Innovent+ 3D printer capable of working with different metals and ceramics, with a build volume of 160x65x65 mm.
• Facilities include a Nabertherm debinding tube furnace (1100 °C) and a high-vacuum (10^-4 torr) sintering tube furnace (1400 °C)
   

AM Mechatronics

Hands-on Systems Engineering incubator for AM systems and related machinery.

• The lab space includes multiple desktop FDM 3D printers for prototyping, a workshop area, and a project space including various electronics and Arduino elements.

Big Additive Manufacturing Facility

• Large robot arms equipped with a pump capable of making Big Area 3D prints in polymers and construction materials. 

Gas Atomizer

• The custom-built atomizer is unique in Denmark, designed to produce fine metal powders by atomizing molten metal using a high-pressure gas stream. It offers full control of the nozzle design, temperature, gas flow, chamber pressure, oxygen concentration, etc.

• It enables the study of the atomization process and advanced alloy powder development. The latter is critical for further development and application of metal additive manufacturing, as well as maintaining the AM Lab's leading position in this field.
