Hello, I’m working on a project that requires TPU/EPU parts for vibration damping and energy absorption, with a focus on resilience and tear resistance. I’m comparing HP MJF and Carbon DLS™ for these parts in terms of print speed, surface quality (for exposed parts with fine detail), and cost efficiency for small to mid-sized batches. I’d appreciate insights from anyone who has experience with both technologies, especially for similar applications.

Hello everyone, I’m working on a DMLS turbine blade with some overhangs and complex curvature, and I’ve run into challenges with support structures. I’ve noticed that removing the supports leaves marks and sometimes even warps the part, especially with unsupported angles over 30°. I’ve shortened the CAD file, but I’d appreciate any advice on minimizing the use of support structures while still ensuring the part prints correctly. Are there specific design modifications or strategies that have worked well for you to reduce post-processing issues like warping or stress? This is my part and a section through it:

Hello, I’m trying to better understand when a 4-axis CNC machine is necessary for machining curved features. I know that a 3-axis machine can handle some curved cuts, but I’ve heard that certain designs require a 4-axis for more complex geometries. Can anyone provide specific examples of curved features or shapes that a 3-axis machine can’t handle, and why a 4-axis would be required instead? I’d appreciate any insights or details on this nuance.

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?
