• Fabrication of microparts and microstructured parts using nanoscaled ceramic materials

Methods

• Surface modification of the nanoscaled powder
• Mixing the modified powder with the INM basic binder system
• Processing on a commercial injection moulding machine
• Debinding by thermic, solvents or supercritical media

Results

• Defect free fabrication of ceramic parts in sizes of 1.5 to 10 mm
• Structuration between 100 and 500 µm

• Micro pump case and rotor
• Gear wheels for micro gear boxes
• Micro flow meter
• Microreactors
• Micro optical parts (filament plug)

Benefits

• High forming precission
• Low surface roughness
• Near net shaping
• Less aftertreatment
• Low cost fabrication
• Environmentally round processing conditions due to binder recycling
