Selection method for WAAM

Wire Arc Additive Manufacturing (WAAM) is a technique that allows 3D printing by means of a welding torch on a robotic arm and specialized process settings. The technology has great potential and is therefore seen as a Key Enabeling Technology (KET). The aim of the research is to improve acquisition processes for Wire Arc AdditiveContinue reading “Selection method for WAAM”

Biz 1

Exploration of the possibilities of 3D metal printing. What possibilities and limitations does 3D metal printing have as a production technique? What new challenges does this present for designers? 3D printing requires a different approach to the design process. The research group Industrial Design has composed design guidelines for this. Business economic aspects have alsoContinue reading “Biz 1”

Biz 2

Establishing design and production guidelines. Together with 5 regional partners; Thales, Z-tech, AWL, PM-Aerotec and Aeronamic a research project has been set up for the development and anchoring of knowledge about 3D metal printing. This is done by means of specific questions coming from the companies through generic technical research and developments of future-proof specificContinue reading “Biz 2”

Spare parts

Developing a 3D repair cycle in which old or broken parts are scanned or measured, digitally repaired, 3D-printed and reworked, until they are ready for use. 3D printing technology (Additive Manufacturing, AM for short) has undergone strong development over the past 10 years, with special applications. Plastic is a well-known 3D printing material, and newContinue reading “Spare parts”

Spare Parts Case 5 – Water pump housing II (Motoren Revisie Meijerink)

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)”

Spare Parts Case 4 – Water pump housing I (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)”

Spare parts Case 3 – Lever (Oyfo)

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)”

Spare parts Case 2 – Wire guide (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)”

Spare Parts Case 1 – Piston

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”
