Commercial 3D printer businesses?

Unfortunately Willy the print doesn't always resemble to drawing. Sometimes the drawing is beyond the capabilities of the printer and other times the slicer settings are not correct and/or the printer hasn't been dialled in properly.
It is similar to giving a blueprint to three different machinists with different skill levels and different machines.

And this applies to a Selective Laser Sintering machine costing between $20K and $500K as well? They talk about it being the best process for fine details.  This part wasn't done on a printer using an extruded filament. I have to wonder if it would have come out better if it had been.  Oh well, it is what it is. It's my first experience with 3D printed parts so I didn't know what to expect anyway.

Do you have the file for that part that you could post? I could print it and see if I get better results than you got from the place that did it for you. Ed

Ed, I do have a couple of different files for it yes, but I have no idea of what the difference(s) are between them. MikeWi said here that using a .3mf file would remove any problems with dimensions so that is what I sent to Xometry to make the part from. I didn't want to bother you by asking because I know you said you were still working out doing 3D lettering for your own boxes.

I also have a couple of .3mf files but it looks like that file type is not allowed here as an upload. Edit: Additional info... Quote:Printed with PETG, 0,2 layer height, 25% infill I'm getting the feeling I should have sent them the other .3mf file ~ the one with “Height Range Modifiers”. Since I have no clue what that means, I sent them the one without height modifiers.

If it's in the stl file then I can print it. I just don't know how to create the lettering in the 3D model yet. Alas, that part is too big for my printer to print.

I opened both files in PrusaSlicer and they look the same to me. I'll try printing both using PLA and see what happens.
Oh, and the part fits if put diagonally. PrusaSlicer did that on its own. Ed

What I meant was, instead of putting it into a longer box for shipping Xometry stuffed it into a smaller box diagonally between corners of the box. I think they had to bend it a bit to get it to fit in the box. That's why I'm hoping it might straighten itself out again when I attempt to dye it a darker color to make it more readable than white on white. From what I gathered the file with "modifiers" has adjustable settings or constants available in the software? I don't know.

What I was referring to was when I loaded the stl file into PrucaSlicer it did not place it diagonally so it wouldn't fit the printer bed. I never even thought of trying to rotate it to see if it would fit diagonally. But when I loaded the 3mf file into PrusaSlicer it put it diagonally on the printer bed so it fit. Not sure why it placed it differently between the two file types. Ed |
