Cooporation with Fontys Centre of Expertise And Objexlab Assignment : Is it possible to manufacture a monolithic bondhead including thin flexures using additive manufacturing? (Maintaning existing specifications) Student: Marco Teeuwen
Additive manufacturing Adding layers of material Selective Laser Melting (SLM)
Test models Fontys Objexlab Stainless Steel Print jobs stopped Support structures Straight flexures before removing Support structures removing problematic
Test models Supplier X 2x Titanium and 1x Stainless Steel Broken leaf springs Bended leaf springs Problems occure at removing support structures
Test models 3D Systems 4x Titanium Leaf spring 1x Titanium Cross flexure Straight flexures Edges in the reinforced sections 45

Costs comparison Conventional (serie 8) = 100% Printed (serie 2) = 80 % Excluding: - Vacuum pipet (exchange part) - Some conventional postprocessing still needed 27 nexperia.com
Conclusions Is it possible to manufacture a monolithic bond head including thin flexures using additive manufacturing? Yes! 0.20 mm printing should be possible in Titanium and Stainless Steel Print tolerance ± 0.040.. ± 0.050 mm Printing of thin structures standing will give the best results Leafsprings at 45 (no support structure needed)
Next assignment Perform a life (fatigue) test Investigate the effects of a treatment after printing Implement into machine Check on dynamics performance
