Necesitas crear un modelo 3D para tu último diseño. ¿Cómo puede encontrar el servicio de impresión adecuado?

If your new to manufacturing I would suggest you take a look at "what your 3D printing company requires" in order for you to get expected results from your design. Take a look at some industry standards such as - The "American Society of Mechanical Engineers Y14.5 - 2018 Standards book" The Y14.5 standard is considered the authoritative guideline for the design language of geometric dimensioning and tolerancing (GD&T.) It establishes symbols, rules, definitions, requirements, defaults, and recommended practices for stating and interpreting GD&T and related requirements for use on engineering drawings, models defined in digital data files, and in related documents.

For starters, the setup for this discussion is about creating a 3D model for your latest design. So I'd start with the question you ask - "How can you find the right printing service" - and whether it's the right one. While 3D Printing is a good option for prototyping especially, your design might lend itself more effectively to machining or casting. So you may want to first consider whether your new part is appropriate for 3D printing in the first place. 3D Printing is quite rarely the right solution for manufacturing at scale. Instead, perhaps consider an engineering firm or CAD designer that has experience with multiple technologies - even if they don't carry any equipment in-house. Technology agnosticism is a good thing early.

When comparing technologies, make sure that you aren't narrowing your scope too early. Constructing parts additively is often the most economical choice early on...but only rarely is it the best choice at scale. Machining or casting might be better, and in some circumstances allows you to prototype in your end material better than 3DP. 3DP is sometimes a great choice though, especially if your design is highly complex. I'll briefly note that the setup comments are all polymer technologies. For metal, binder jetting, powder bed, and directed energy deposition, and cold spray technologies might all warrant investigation.

Not much to add here. Checking a reputation is always a good idea. I would separately add that there's a degree of consolidation in the broader 3DP space currently underway. So I would advise you to not to dismiss a newer provider if their leadership team has strong roots in the industry or a great academic background.

Samples are hit or miss requests from service providers. The best are often very busy. And to be honest, a sample off of a printer is unlikely to provide tremendous insight. It's their ability to deliver against a particular spec and tolerance requirement that matters...you're not going to learn that from getting a random part built off a CAD file you don't have access to. With respect to quotes, that's a necessity, obviously. Instead of expecting them to provide a part that matches your finish, you can certainly ask for a picture of the finish...that's easier. You have to remember that your first part probably costs less than $100 and they are probably losing money on it when considering time investment. Make demands accordingly. ;)

This is reasonable guidance. Communication is important. With that said, once they have the design file, there's not a ton more to do. And being too squeaky a wheel can get you a reputation as a trouble customer. It's ok to check in sporadically to see if things are tracking on time though. Also, if you have a design revision - or expect to have one - notify them as early as possible. There is a fair bit of work involved in build preparation - your parts are probably being printed along someone else's and the space of the build has to account for that. So quantity and design changes can reasonably set back your delivery timeline, even if the print hasn't started yet.
