Looking to Print a Caboose...

[Chris333]

Also I think Tony has a newer Photon with PhotonS guts. I have one as well and can't get it to work right. Still using my old(er) one.

[SkipGear]

Yes, I have a Photon S.

On my 3rd try on the floor. Keeps failing on the the very bottom step, the last 2-3 layers of the print. Made them thicker on the the 3rd and adjusted step and bolster overall thickness. Steps that looked fine on the computer screen were too short compared to the bolster thickness. Tweaked both, also added some reinforcement beams on the inside to keep the floor from warping, still thinking about what to do for a coupler pocket on it.

I would figure to just put some guides in that will hold a 1015 box in place.  If you can include a dimple to keep the drill bit centered.

Not sure where the line just above the sill came from, hasn't shown in any other prints. Next step is research brake hardware and create a coupler mount, oh, and a few more thousands clearance between the floor and body because what fit perfect before paint, is a bit tight now.

I see that people are printing flat to the build plate. Everything I have read says you should print at an angle. What are the pros/cons of printing flat?

[SkipGear]

The main reason I have found for printing at an angle is so that you don't have a large flat surface sticking to film in the bottom of the reservoir instead of the build plate and causing failures. On items with curved surfaces it tends to smooth out the layering effects also.

In the case of this print, the smoothing effect would take away from the vertical board seams which is what started this whole topic. Also building flat minimizes print time and wear and tear on the machine.

On a steel or smooth side car, printing at an angle would be better and was going to be the next trial if the floor print failed again.

I'll take it!

Great progress!

That horizontal line along the bottom of the sides is strange.  There are also some fainter horizontal bulges along the line of the top of the windows and about the level where the stiles (horizontal mullions) are in the windows.

I think a lot of the artifacts are due to the fact that my fep film is due for replacement. I can see distortions in the film transferring into the prints.

Looks like there's not much tightening up left to do on that one.  Can't wait to see how it looks finished.

Anybody want to design an etch for window awnings, end railings, etc. and make this a real kit?  The vertical steps for the I-5 with its wide platform are well suited to etch.

If so, remember that B&O ladders went on the left sides as you face the ends of the caboose.  And the brake wheels were horizontal on the I-1 and the I-5 up into the 1960s.  Some of the I-5d got vertical brake wheels starting in the early-1960s, but others still had horizontal brake wheels into the 1970s, even one that had been rebuilt with plywood sides (C2048, by 1971).

[SkipGear]

I plan on adding the awnings to the next print as an experiment although they are not hard to make separately using some brass shim stock. The railings on my wood kit were pieced together from MT caboose endrails and some soldered together brass.

Next step after the floor details is a modernized I-1 floor with the vertical steps and wide porch. Then modify the body into an I-5 to fit on the modernized floor.

Did anyone else see Tichy's release of a decal set that covers 35 varieties of B&O cabooses? Does that solve the decal problem for this project?

Will get back to work on this shortly. My father passed away suddenly on the 24th and I have been back and forth to his farm 3 hours away searching and cleaning on my days off.

 I have a new Photon Mono X that should be here Monday and the caboose will be the test mule for it.

Sorry to hear that.  My condolences to you and your family.
