Reply to "3-D printed products - any negatives ???"

I posted photos of my Seaboard Air Line motorcar 32028 a while back, 3D printed by Zak Pabis.  Zak did a fine job as far as I'm concerned but there were a few things I saw in the printing method that have to be dealt with to make the model look good.

Depending on the direction of printing, there's going to be print lines that must be sanded or they will show.  Not a lot of sanding, but it takes some work to get things smooth.  I've had this for a year now so maybe with the newer printers (which he may have now) this problem has been solved.

Here's a photo of the model as I got it:

You can see lines all along the surface, but the ones on the top don't really show once painted.  But the lines on the vertical rear of the body had to be filed/sanded to make them disappear.  There weren't lines like this on the sides that I could see.

This thing is 18" or so long and he had to make it in 3 pieces, then glue it together:

It's as strong as any store-bought model I have so that's not a worry.

Once painted, I thought it looked fine and I'm proud to have it in my collection:

Here's a photo of the end after filing/sanding and with a light coat of paint:

Last time I talked to Zak he was going to university and had to halt his 3D offerings for the time being.  I haven't visited his website so I'm not sure if he's still active or not, but I would definitely buy from him again.  3D printing gives us a way to get something made that the regular model makers just aren't going to offer.
