I can't see any now, & that's after I enlarge the image to full-screen!

The 1/700 Avro 504 came out great! How did you support it?

Nose up at 45 degrees. Supports along the trailing edges of the wings and around the tail and landing gear. I'm trying a second batch, nose down inverted. The first all had a bit of warping on the wings and they have a noticeable taper.

I'm not only jealous of the build, but even more so of your eyesight

Love that statement and one I can generally agree with

What resin are you using? Clear resins can have a slight bleed-through exposure. That may account for some of the warping. Still, really impressive results for 1/700.

I'm using a transparent resin. I had suspected that might well be the case. I had bought transparent resin so I could print canopies as well as the rest of the model. But I'm beginning to think that making vac form moulds would be a better bet for that feature. Once I'm out of transparent I'll move onto bog standard grey.

No I meant in general. I've printed a few 1/72 aircraft on my FDM printer. I was hoping that with a clear resin I'd be able to get better quality prints and that would include canopies.

I've tried printing transparencies with clear resin. The results were poor.

- The clear resin I was using (Anycubic clear) yellowed a bit after curing. There are other clear resins that yellow less, but...
- internal defects and even the occasional layer line will be visible, even after sanding and polishing.
- A canopy thin enough to minimize yellowing and internal artifacts may be too thin to survive the polishing/sanding required to make it transparent

Polymaker makes a clear filament that can be smoothed with alcohol. The main drawbacks are the cost and the surface durability.

I'm not saying that 3D printing a transparency with a resin printer is impossible - it's just that it would be far easier to print a master in an opaque resin, smooth it and vacuform the canopy from it.

That was my first thought until I read Caveman's reply

Actual ship progress in a ship topic...



Looking more like a ship! Got to work out what scheme I'm going to paint her in still. I think she's too late to be in the fetching white, yellow and black rig of the late 1800s. Ships boats and aircraft still to add.
