My first attempt at a Shapeways 3d model.
I wanted a GMC Crackerbox and the only place I could find one was Shapeways (I was warned). Model is printed in nylon white versatile plastic. Finishing this model was different than any other material I had ever worked, HARD - I couldn't use hand saws or Pin Vise, had to use a Dremel with power and speed. Saws and especially drill flutes clog very easily. I used sandpaper coarser than ever before to even attempt to smooth.
About four coats of white paint with a sand between each coat. Wet sanding doesn't work like normal and the very porous material takes about 3 days to dry good after being wet. Final coat of Scalecoat II whit paint with a minor final dry sand (after 3 days drying) and then 5 days for all to dry well before the color. This for the cab.
The model comes as a single axle and I wanted a tandem, so I cut a frame from a Shapeways Dodge L1000 to get the tandems and spliced with brass channel. (the Dodge will become a single axle daycab and a later project). I never could get the fuel tanks to clean up properly. Some Don Mills metal tanks may be in the future. Wheels are by Don Mills as well as Mirrors and Horn.
If you remember the 70's show Movin On with Claude Akins (Sonny Pruitt) and Frank Converse (Will Chandler), they drove a pretty green Kenworth. The inspiration for this truck was the truck driven by Art Metrano (Moose) and Rosi Greer (Benji) called the Pig Pen. Except the Pig Pen never looked this good (even if not up to my normal standards). I know I need a different trailer for the real Pig Pen.
I have a Shapeways Holmes 750 printed out of a better plastic (mucho more dollars) I and am going to put on a Revell Chevy 2 ton, the better plastic is much less grainy,
Hard to tell with pictures, It's no metal finish Corgi, but better than nothing and not TOO awful bad. As I was warned, it is possible to get a decent model (I didn't say super) but it is a lot more work and working with this material is a horse of a different color.
Others that have used 3D plastic, I'd love to know what I did wrong or could have done better to get a better finish.
