Hi all, I’m designing vibration-dampening pads for a small industrial machine. The pads need to isolate vibrations effectively without being too stiff, and the machine runs with moderate weight and speed. I’m looking at polyurethane and silicone as material options, but I’m unsure about the ideal Shore hardness for this application. What hardness range would you recommend for balancing flexibility and load-bearing capacity?

Hi everyone, I want to use snap-fit joints for a 3D-printed enclosure that will be opened relatively frequently for battery replacement. I will be using ABS or PETG as I have read that they hold up well to cyclic loading. Can anyone provide insight into how 3D-printed snap joints compare to injection-molded ones, or should I explore alternative methods?

Hello, I am a mechanical technician student at the professional school of technology in Bochum. If you have anything interesting for the school program or for my future independence, I would be very interested.I also have to do my technician project.I would like to become independent and hire a few people who would like to work.

Hello, I’m working on a project that needs a lot of precision, and I’ve always thought parts should be fully reproducible from the technical drawings alone, without needing a 3D CAD file. Lately, though, I’ve heard that even low-tolerance features need to be dimensioned on the drawings. Is it normal to include those dimensions, and how does that affect the manufacturing process? Just trying to make sure my drawings give all the info needed for accurate production. Thanks, Tamir

Hi, I’m currently designing high-precision parts that require detailed GD&T specifications and I’m concerned about how well my design intent will be understood by manufacturers. What are some of the most frequent issues you’ve seen when it comes to manufacturers interpreting technical drawings, particularly for parts with complex tolerances and GD&T? Are there common areas of confusion or miscommunication, and how can I make sure my drawings convey all the necessary details as clearly as possible?
