Passivation of stainless steel for harsh environment
Hello!I’m working on a part that will be used in a harsh environment, so I was thinking of stainless steel 304 as a suitable material. I also would like to add a passivation finish to improve the corrosion resistance of the part.Are there standardized grades or methods of passivation for stainless steel? What “grade” or specific type of passivation should I specify on the engineering drawing to ensure optimal corrosion resistance? There’s lots of info out there, but I’m a bit confused. Can anyone offer some straightforward guidelines?Thanks in advance.

How do you balance aesthetics with manufacturability in product design?
Hi!Currently, I’m working on a new consumer electronics product, specifically a sleek, modern-looking smart home assistant. This device integrates voice control, home automation, and entertainment features. However, it’s tough trying to find the right balance between aesthetics and manufacturability. Our design team has created a sleek and modern look that our marketing team is excited about. However, our manufacturing engineers are worried about some of the aesthetic features that may increase complexity in production, leading to increased costs and possible delays.We are specifically grappling with issues around our choices of materials, design intricacy, and finishes types. For example, we’ve used a particular high-gloss finish that looks stunning but is prone to showing fingerprints and has to be handled carefully during assembly. Also, we’ve included several curves and unique shapes, which make some items difficult to produce consistently on our current manufacturing line.Did anyone ever face these challenges? What did you do when faced with such trade-offs? Between the attractiveness of a visual design and one that is less costly but more basic, what did you opt for? Can somebody give me some advice on how best I can work with both the design and manufacturing teams, to come up with a solution that will satisfy both sides?

How to design a 3D-printed snap closure that works perfectly?
Hey guys! I’m hoping I can get some technical advice in designing an enclosure for a scientific instrument — it’s a portable and remote logging device. The device I’m enclosing is about 100 mm square and maybe 20 mm high at the maximum. It has no display, it’s a data logging device, so we will get data off it via wireless after each test cycle. I’d love to make a case that snaps together, to keep metal parts like fixings to a minimum because of some rapidly changing magnetic field issues and concerns about eddy currents.I’ll only need a small number of these for testing right now, so I need to 3D print the case, but I need to design so it will tool ok eventually. If the test results are good, the volume will follow.Where do I start? I’ve had a play with some design ideas, but it’s impossible to validate them as our FDM printer really can’t handle either the fine detail or the strength. My snaps didn’t engage much and broke off really easily!This is what the snaps look like, but they just break off so plz hlp!

Material Information
Good morning everyone,I am intending to fabricate a model for biomedical applications, and the Xometry staff has suggested stereolithography as the fabrication method and Industrial Transparent ABS-like material, which can meet the basic requirements (strength, low moisture absorption, and transparency). My concern is about its prolonged use, especially if in contact with liquids that will in turn come in contact with biological material. An additional problem is reuse of the part, that is, between uses it will be necessary to sterilize the part, and since it does not withstand autoclave temperatures, the only way available to me is with ethanol. Does this lead to damage to the material?Thank you in advance for anyone who can help and give me an answer.Good day to all,Federico
