It's difficult to tell how rough that actually is, I think I'd still be interested in one for a template if nothing else.

Overall I don't think that is a bad job at all. It probably wouldn't take anymore work on it than if you had a resin kit. Do a little work on it and put it on a shell. Show us the process if you don't mind and let's see what the end result will be before anymore judgement is made.

That is pretty cool.
If I may suggest, remove the sand fill hatch. Thi sis a detail part that is much better looking in injection molding. Simply put a small drill guide hole. it will help with the smoothness of the nose top.
Maybe do the battery box covers and sand access doors as seperate parts. This way the printing can be done flat and maybe get a good smooth surface.

Oh, also the heaqdlight housing. Put holes to line it up or holes to mount the DA part.

We borrowed a Kato SD40-2 cab to measure the window glazing, but I didn't test the fit due to fear of breaking it when I removed it. Does anyone have a surplus set of glass I could get ahold of?

So here's the new plan, because this seems to be the best way to keep things from suffering in the quality department:
We are going to print a cab from another source to use as a master, and have them cast in resin. We will be taking preorders when the time comes, details will follow then. I anticipate shipping resin cabs by the first of the year at most.
If anyone has that window glass, I am still interested in the set.

Is resin a better way to go with this cab? I really don't know much about either the 3D printing or resin so I am curious to know which is better. I also have a idea I want to see about bringing to life.

I also have a idea I want to see about bringing to life. 3D printing can handle the detail requirements, the problem is using a better material and print resolution is prohibitively expensive to use for final products. By using it for a master, it's possible to get good quality resin castings and have the best of both worlds. Speaking of resin, if anyone has a good amount of experience with casting and would like to help in this project (compensated, of course), PM me.

Keep up the work.......even if it looks as good as the test shot you showed....I am in for a few. I don't mind some clean up work.
It can't be any worse then the USELESS Phase 2 SD70M cab and radiator set I just got.
Now for an SD60E cab!!!

Liengineerbob...LOL. I can laugh because I have 3 of these cabs and when they say their a bit rough, they aren't kidding. One was so bad that I tried to make the stock cab into a Phase 2 cab. Lets just say I reverted back to the Phase 2 cab.

Resin would be the way to go, BUT, You could not use the master pictured. The biggest issue would be the number board area. I'm assuming its hollow, and as such, would create a huge undercut area in the mould. The silicone used for moulds can flex, but it cannot move that much. The solution would be to either make the number board area thicker (more solid), or have it as a seperate piece.
When a silicone mould is made, it picks up ALL of the surface details, good and bad. I made a mould once of something that had been decaled, and every cast that I made had the shadow of the decals visable. So, the cab surfaces need to be smooth and blemish free. Also, the smoother the surfaces, the longer the mould will last.

Did the fine details like the numberboards and grab holes make it through the printing process? Will you be able to show us a primered version to better show the finish?

If most of the cab is a standard EMD cab with modifications, why not just make the modified part of the cab and use a Cannon cab for the rest?

I agree with Randy. I was thinking the exact same thing, though it would be nice to have an entire 'replacement' cab as well.

As I understand it, 3D printing uses an Isometric cad drawing which is copied by a special printer which recreates the 2D drawing in 3D with the use of an ultra violet laser and plastic and/or resin powder. Not quite. 3D printing requires a 3D file, and usually a stereolithography file (.stl) at that.

There's not much point using a cannon kit for this. The battery boxes are the challenging part in my eyes, the rest is easy. Sent from my GT-I9100 using proboards

At the time when I posted my question on NORFOLK SOUTHERN's ADMIRAL CAB on a different site, it seems that a few had a good laugh when I was asking about it which was disappointing not to mention discouraging.

Most non-detailers don't get it. Best way to hide ignorance is to laugh.
