Default 1/200 3D printed DHC-4

I thought I'd share some of these photos with you. This model I've been working on was going to be diecast but now for various reasons I'm not so sure. The design work was undertaken by a very capable person in China. Anyway, as part of the review process I decided to get some 3D prints done of the model at Shapeways. I have to say getting 3D prints done has saved me $$$ before committing to tooling which would have not been up to scratch, and should I decide to make the thing at a later date the money spent on 3D printing has been money well worth spent. And 3D printing also highlighted the tricky centre of gravity issue too during the design process, which seems now to have be resolved.
The silver and green paint printed examples are the first print I had done before the latest revision.

As you can see, although the shape of the aircraft is correct, there was rather limited detail on parts such as the wings.


The latest version has panel lines on the wings and detail on the tail (you can see the detail on the top and underside of the wing in the following photo) and nose of the aircraft. I've just received the latest parcel from Shapeways and hope to have the model assembled shortly. This model will be left in a grey primer finish, as the extreme frosted detail Shapeways use is a horror to work with, extremely brittle, its porous like sponge, and doesn't take really take the paint like a plastic or resin model does. For model aircraft, I would only use the 3D printed material to make detail parts or masters for white metal or resin casting. Not for completed assembled models. To assemble this latest model, I'll be using canopy glue, as its much easier to undo something on brittle material.
Mind you, I had some one piece 1/200 military trucks printed and they turned out great due to their compact size.



A 3D picture of what the latest version its supposed to look like. If I do eventually make the tooling with somebody, there will be some further adjustments to be done to the 3D model.

Great to see someone showing interest in the Caribou! Looks really nice, I wouldn't mind building one of these. Is it intended to be available with both the original radial engines as well as turboprops?

I have finally completed the latest Mk 2 print with radial engines. The wood pattern on the side of the fuselage is from the printing process. The 3D material is too hard to work with, so all I've done is finish it off with fine grey primer.



And the Mk 1 3D print alongside a 1/200 Hogan Sabre.

I have a question...already looked at Shapeways site and didn't find an answer, but if submitting a model for printing, should it be broken down like a kit or can it be essentially printed all in one piece? I have a subject of my own to submit one of these days. This Caribou looks like a Caribou despite the rough finish, real nice work.

The greater the complexity of the model the more likely it will have to be broken down. There are models over at shape ways that are one piece. Those trucks you see in the photos were one piece prints. The latest version that I have printed was done in extreme frosted ultra detail finish, their finest printing available, at close up it still looks rough due to the stepping process. You will get a evenrougher finish on most 3D printers and I had trouble finding a printing service aside from Shapeways that could do so fine. I only had these printed to assess the 3D model, the model is nearly finished now.

Great work, and I imagine the process will become more refined with time.

I imagine 3D printing will be a boon to this hobby, particularly with interesting but low-demand subjects such as the Caribou.

None of the local 3D printing bureaus in Australia could print to the resolution that I required, so I ended up at Shapeways who are not the cheapest guys in town but are committed to maintaining customers intellectual property rights. The silver aircraft was printed in frosted ultra detail while the grey aircraft was printed in the newer frosted extreme detail.
http://www.shapeways.com/materials/f...detail-plastic
3D printing the 5 bladed propellers didn't work out as the 3D print material was too fragile to work with, so I took the propellers off a 1/200 JC Wings Shorts 360 which has metal stamped and are a close match.
I think it would be at least 5 to 10 years before 3D printing equals the quality of injection moulded plastic for smaller scales, 3D printing is popular in the larger scales for railway and military modellers, but the smaller the detail, the harder it is to achieve for scales such as 1/144 and 1/200.
