So far I have been pleasantly surprised at the dimensional ability of mine. I specified a 3/4¡± hole and printed the part and a 3/4¡± shoulder bolt was a snug fit. Small holes I don¡¯t get so lucky on, but they can be chased with a reamer or drill bit. I tend to print with extra layers around the shell, or even print solid and have had decent luck with threading holes and such.?
They are a tool like anything else, useful to an extent and great within their limitations.

Totally the way to go, we use ours alot for that. lately we have been designing a lot of electrical connectors and they are great for that, I have also made quite a few assembly fixtures for production. I have the most issues with round holes, they are never perfectly round so where critical I undersize then chase it with a drill bit also we usually have to adjust the model to print to an exact size but its not always that critical. I have used dovetails to connect parts and that works well on the markforged printer.

I have a Creality CR-10, it¡¯s about 3 years old now I think¡ It¡¯s not by any means a great printer, but it does up to a 12¡± cube and I get pretty good prints out of it. I use it a lot for prototyping parts and finalizing designs. It¡¯s a whole lot easier to design a part, start up the printer and let it print all night and check my finished part in the morning, and then make any changes before I commit to actually machining anything.
Brian, which 3d printer do you have and do you like it?
We have a Markforged, Form3, zprinter 450 and a Metal printer in our Lux plant.?
I like the Markforged the best and the zpinter the least

I use my 3D printer a lot to test fit things, make fixtures to hold parts for laser engraving¡ all sorts of things. I recently was helping my daughter on her kitchen remodel and she picked a three dimensional tile for her backsplash. It didn¡¯t work so well with the electrical outlet trims, so I used my 3D printer to make extension rings so we could tile up to a straight edge and then put the electrical trim on and have it look right.
Before we installed the tile¡.

We have been using 3d printing for 15ish years to iterate on designs but thats pretty much it, if we need a precise parts metal needs to be cut, even parts that come off our metal 3d printer are useless unless secondary operations are done with traditional machinery.?

?Mark you are an early adopter,
Not sure there are many people out there 3D printing stuff to get it produced somewhere else, but I like it,
