Materials Architecture Lab

Architecture structured materials are produced by 3D laser printing and acheive a high strength-to-weight ratio, large surface area and high resilience for gas storage, battery electrode and fuel cell applications.

3D Laser Printer

This instrument is one of the advanced additive manufacturing solutions based on Projection Micro Stereolithography (PµSL) technology. PµSL allows to 3D print true microstructures with ultra-high printing resolution (2 µm~50 µm) and printing tolerance (+/-10 µm ~ +/-25 µm). Micro 3D printing is the optimal manufacturing process for a variety of 3D printing applications across a wide variety of industries such as medical devices, electronics, microfluidics and micromechanical devices. The combination of ultra-high resolution, accuracy, and precision allows for more intricate, exact, and replicable parts. Especially, the performance of this instrument can be achived 2D optical resolution ~2 µm and layer thicknees 5-20 µm with printing volume 38.4 mm (L) x 21.6 mm (W) x 10 mm (H), suitable for microelectromechanical systems (MEMS).

Critical-Point Dryer

After printing, the architectured material is dried, and the gradual conversion of water to vapor may cause the collapse of the designed micro-structure. To overcome this issue, we employ a technology that can remove the liquid within a desired structure by controlling condtion beyond the critical point of water to avoid the damage from phase change. The critical-point dryer allows fully automated preparation and drying of samples such as laser printed photopolymer and microelectromechanical systems (MEMS) for SEM analysis. A new filler concept has been developed to reduce CO2 consumption and drastically reduce processing times. For user safety, a software-controlled cutting function has been introduced and a waste separator has been built-in.
