A similar water pump housing case from Motoren Revisie Meijerink was presented as a more complex geomery that includes cavities and bulges. Digital redesignThe part was scanned with a 3D scanner of 4C,. The shaft with impeller was still in the housing when scanning. We started with an analysis of crucial points, where a preciseContinue reading “Spare Parts Case 5 – Water pump housing II (Motoren Revisie Meijerink)”

The original waterpump is cast, It is possible to have them reproduced at foundries in Turkey, for example. The disadvantage is that the delivery times are long (8-10 weeks) and no single items can be purchased. This makes single-piece production by means of 3D printing interesting. The intention with this part is to make theContinue reading “Spare Parts Case 4 – Water pump housing I (Motoren Revisie Meijerink)”

Lever (Oyfo) A large switch box is used to convert an electrical circuit with a lever. To minimize sparking, the circuit must be converted quickly. A critical part of this ministry has been broken down. This part was originally a cast part and is no longer in production. Scanning and modeling Several scanners were used.Continue reading “Spare parts Case 3 – Lever (Oyfo)”

Wire guide (Oyfo) A textile machine (image below) distributes a large spool of thread over smaller wooden spools, which are used as a weaving thread in another textile machine. There are thread guides on them, which move back and forth quickly and guide the thread evenly over the wooden spools. The original wire guides areContinue reading “Spare parts Case 2 – Wire guide (Oyfo)”

Piston A piston moves back and forth in a cylinder and has a complex geometry. The piston appears perfectly round, but is slightly tapered to avoid jamming. High demands (thermal, mechanical and dimensional tolerances) are placed on a piston and it is exposed to varying temperatures. Pistons can only be ordered in large quantities, butContinue reading “Spare Parts Case 1 – Piston”

Practical implementation of generative design in the industry • Goal: The goal of the assignment is to reduce the time it takes to design and produce a non-standard welding jig pusher. This means that the process was monitored from order to delivery of the welding jigs. Here, it is examined whether time and therefore moneyContinue reading “Biz 2 Case 8 – Parametric pushers (AWL)”

Radiation-damping diffusers (Thales) • Goal: The goal of this research is therefore to see what can be achieved with the 3D printing of an air grille for attenuating radar radiation, Thales’s requirement for the grille was to achieve 60 dB of attenuation for the X band.• Approach: FEM simulations in COMSOL and experimental tests usingContinue reading “Biz 2 Case 7 – Radiation-damping diffusers (Thales)”

Robot gripper (Z-tech) • Goal: The goal of this project is to have fully analyzed the current gripper (figure 1.3) by the end of the graduation period (31 June) (1) and to develop a new gripper on the basis of this analysis (2) with metal printing in mind (3). The gripper must be fully substantiatedContinue reading “Biz 2 Case 6 – Robot gripper (Z-tech)”

Cooling plate electronics cleaning (Thales) • Purpose: To ensure that after 3D metal printing, during the use of the cooling plate, no powder / parts / semi-grains come loose from the cooling channel and end up in the water.• Approach: practical tests of internal structure printing and cleaning with different techniques.• Outcome: Reduction of surfaceContinue reading “Biz 2 Case 5 – Cooling plate electronics cleaning (Thales)”

Cooling plate electronics (Thales) • Goal: Design a cooling plate with a high cooling capacity and a low pressure drop that is manufactured by means of 3D metal printing.• Approach: van den Kroonenberg design methodology.• Outcome: A cooling plate has now been developed that (with a scaled cooling surface of 4500 mm2) provides 13.6% betterContinue reading “Biz 2 Case 4 – Cooling plate electronics design (Thales)”
