That's very impressive Bo!

It was about time someone to do it!

This photo shows how to use a small strip of .004" (~.12mm) thick aluminum to clean the support material from between the fins. the strip is about 2mm wide. Start from the top, back row and push between the fins at approximately 45 degrees towards the front of the radiator. it should easily push right through.

I recommend skipping the acetone bath or going very easy -- just a few seconds at most -- lest the fins start to warp. Instead try washing the part gently in lukewarm soapy water.

Veery nice, Bo, but I continue to ask myself why the 3d printing service still produces items that have the printing grain, while some dental factories produce shiny theets with their printers.
Well, they use ceramic but it seems that the printing resolution is muche better.
Anyway this is not a criticism at all, since your items are enviable, we really needed such masterpieces.
I think you're raising the bar, but the technology around you still lags behind :-{

It's true, although I see the glass as more than half full.

-- the ability to create and distribute a handful of ultra niche-parts with virtual zero tooling and overhead outweighs the disadvantages. (I mean really -- what is the worldwide market for Albatros fuel valves? Well I have a pretty good idea, because I know how many eyeballs have looked at my product page -- and the number is not that large lol.) But this stuff isn't perfect and I am not pretending otherwise ...

I agree, Bo
I can only dream the moment when we can design and print any model that we wish and possibly have a stash back-uped in an hard disk.
We are only a few and the 3-d printing is opening new possibilities.
Now we need only a better definition (possibly it is already there)
and ... pigments - yes, just imagine if we could have our models not only 3-d printed, but also coloured.
Imagine a albatros wing that comes printed in Aviattic lozenges
The card-modellers are lucky here... a lot of time is spared

It is with tears in my eyes that I contemplate this,but kits could be obsolete within the next 7 years.

What is FXD? Is that the material they're made from?

Sorry, for the jargon -- though I think I explained this in the FAQ sticky... FXD is short for "Frosted Extreme Detail (Acrylic Plastic)" it denotes both the material and certain technical specs. Their vendor calls the material something else, but anyway it's the exact same photopolymer as "FUD" (Frosted Ultra Detai -- the best rez stuff they had a few months ago) and printed on the same types of machines -- the only difference is the Z resolution is higher with FXD -- only 16 microns per step vs. 29 with FUD. The X-Y resolution is the same, but it was already quite high.

A quick recap -- most 3D printing processes work by depositing layer upon layer of material one way or another, each step moving the z-axis one tiny increment...

So the Z resolution is nearly doubled with FXD over FUD, and depending on the orientation of the detail in question, the difference can be quite dramatic. For instance the T&B radiator was a total failure in FUD as many of the fins fused together.

James, you are a one-man WWI AM cottage industry support juggernaut! (Thank you!)

Absolutely superb Bo.

Awesome Bo! I have to get 2 of these, one for the DIII and one for the DII. Should be close enough for Government work

Bo,
Thanks for the detailed instructions. They will come in handy soon!

These look breathtakingly good, Bo.
