Physically printed optimal mold (Protype) • Purpose: To determine how flat and smooth a mold can be printed (without finishing operations).• Approach: redesign mold, print mold, testing• Result: We succeeded in printing an optimized mold with a complex cooling channel and a pillar textile that is only possible with 3D printing. However, the print isContinue reading “Biz 1 Case 11 – Physically printed optimal mold (Protyp)”

Smallest fluid channels (PM Bearings) • Objective: To investigate the smallest possible hole diameter that can be printed in a PECM tool (precision tool with very small fluid channels, Precision Electro Chemical Machining).• Approach: Print multiple samples containing various channels (0.2 mm, 0.3 mm, 0.4 mm) and wall thicknesses, cut samples and examine them microscopically.•Continue reading “Biz 1 Case 10 – Smallest fluid channels (PM Bearings)”

Lattice structures • Goal: To determine which mass reduction can be realized with the most optimal and printable lattice structures.• Approach: designing lattice structures and designing test samples with lattice structures, printing samples, performing destructive mechanical testing with the samples• Outcome: Unfortunately the lattice structures cannot handle the required forces, so it will not beContinue reading “Biz 1 Case 8 – Most optimal lattice structure (Thales)”

Topologische optimalisatie (Thales) • Objective: To investigate when topologically optimized (ie computer generated) designs can offer added value for production using 3D metal printing.• Approach: Research into software for topological optimization, and build up experience with its use.• Outcome: The entire process from design to production must always be viewed critically. The optimized result mustContinue reading “Biz 1 Case 7 – Topologische optimalisatie (Thales)”

Improve distribution block (Aebi Schmidt) Doel: Vaststellen van de vrije ontwerpruimte in het (her)ontwerp van een dunwandig verdeelblok dat klant specifiek ontworpen en geprint moet worden. Aanpak: Volumestromen bepalen, FEM simulaties van flow en sterkte uitvoeren, ontwerpen en optimaliseren, printen, testen Uitkomst: Er is een verdeelblok ontworpen dat geprint kan worden zonder support materiaal meeContinue reading “Biz 1 Case 6 – Improve distribution block (Aebi Schmidt)”

Heat pipes (Thales) • Goal: The ability to produce a custom heat pipe without the limitations of conventional production methods is a great added value for Thales. Within the framework of the project, important knowledge about the possibilities of printing heat pipes has been obtained. However, the research is not finished yet. Thales now hasContinue reading “Biz 1 Case 5 – Heat pipes (Thales)”

Hybride prints (PM Bearings) Satge 1: • Purpose: Printing a linear guide with teeth, by printing a teeth made of stainless steel 316L on an existing linear guide made of stainless steel 420.• Approach: Pilot research: printing a stainless steel 316L tie rod on an existing RVS420 guide, breaking it on a tensile testing machine,Continue reading “Biz 1 Case 4 – Hybride prints (PM Bearings)”

Surface roughness (Protype) • Objective: To investigate the relationship surface roughness and draft angle of a 3D printed mold.• Approach: printing test samples, carrying out roughness measurements, testing mold• Outcome: 3D printing at an angle of 1˚ to 6˚ has no negative influencethe roughness, and the relationship between roughness and draft angle has been establishedContinue reading “Biz 1 Case 3 – Surface roughness (Protyp)”

Printed rack and linear guide (PM Bearings) • Objective: To investigate whether the production flexibility of linear rack and pinion guides can be increased by producing them by means of 3D metal printing• Approach: desk research, (topological) design, simulation, printing, testing• Result: 3D metal printing of linear guides with rack is possible• Profit for theContinue reading “Biz 1 Case 2 – Printed rack and linear guide (PM Bearings)”
