Hi, I have two 400 mm cubical enclosures from 20×20 mm aluminum profiles with glass on all sides except one. I need to connect them into a single temperature-controlled unit and keep the joint... read more

Hello! need help - am working on a set of 6061-T6 aluminum control knobs for a small instrument panel, and the surface finish is important since they’ll be handled frequently and remain visible. The... read more

Looking for advice on selecting a gasket material for temporary spool joints during a hydrotest on carbon steel piping in a refinery. The test medium will be demineralized water (low conductivity, no additives), and... read more

hi! For transparent cover for an outdoor sensor needs to stay clear, handle some impacts, and resist sunlight - would you go with acrylic or polycarbonate? Acrylic has better UV and scratch resistance, but... read more

I’m testing the idea of using DMLS Aluminum parts as pre-production prototypes for a high-pressure fluid system. These would be static housings only, not moving parts. Has anyone validated 3D-printed aluminum components under realistic... read more

Hi all, I’m designing a stainless steel impeller for a small pump (diameter around 80 mm). Would you go for metal additive manufacturing or casting if you need tight tolerances on the blades and... read more

Hi Everyone! We’re designing a vibration-damping mounting bracket (approx. 150×80×40 mm) for a small electric motor housing, and we’re considering 3D printing it in a flexible material. Given the operating environment includes oil exposure,... read more

Hi, we’ve started exploring how AI fits into everyday engineering workflows and want to hear what’s working for others. Are there any AI tools or plugins you’re using (or experimenting with) for design, modeling... read more

Hi, I'm trying to make a small gasket like thing with quite a thin wall (0.8 or 1mm) It has to be soft and rubbery a bit like a thick elastic band. It would... read more

Hi, I created a 3D design for a small microfluidic part using SLA (Clear Resin) with internal channels ~0.4 mm wide and wall thickness around 0.5 mm. The function relies on optical inspection through... read more
