Ah ok. Thank you.
I'm beginning to realize that Windows 10 and sound decoders have a lot in common. There are so many things you have to change in order to get them to work the way you want.
My robotics team has a Prusia i3 MK2.

Harrison, do you have your own 3d printer? Or do you borrow one from your school?
The reason I ask is because I have access to a 3d printer for free, but you have to buy your own filament and actually go to the place to get your stuff printed. And they are name brand printers, which means filament is more expensive...
I want to buy my own knock off, but prices for those are also high. I'm wondering if anyone has found a good deal that I missed in my research...
hon30critterI think I can see the same effect on the boiler.
Yes, it is on the boiler, too, Dave. There must be a way of making the rendering "sample rate" or resolution higher. There's probably a trade off between resolution and production time, perhaps?
I'm sure it is something that can be overcome. I've seen many examples of nicely rendered curves in other 3D items.
Regards, Ed
Ed,
The boiler looks much better now that it is painted. It's easier to see all the details.
I wonder if the problem with multiple flat planes could be resolved by printing the generators on end, or any cylindrical object for that matter? I think I can see the same effect on the boiler.

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
SouthgateThere's that expression be careful what you want because you'll probably get it. I was parusing ALCo diesels on ebay, and came across some 3D printed prime movers.
Thanks again to Dan, "Southgate"
Got my Alco engine blocks last week and gave them a quick shot of primer:

They are just a little rough in spots but for the cost, they are excellent representations.
I bought the N&W boiler from a Shapeways designer. Now this is a work of art!
Boiler_on_flatcar2 by Edmund, on Flickr
The boiler shell is hollow and even the flue sheets are modeled! The firebox walls are separate sheets just like a real boiler. Amazing stuff!
Boiler_on_flatcar by Edmund, on Flickr
One little caveat is that I notice in curved designs sometimes the rendering is made up of multiple flat planes to make the arc. In other words it looks like the sheet was bent using a multiple brake rather than rolling stands, if you know what I mean. Sometimes the part can be sanded but other times there is rivet detail that would interfere. There's probably a way to make the "sampling rate" higher to mitigate this but for now I live with it.
You can see what I refer to in the Alco generators in the photo above.
Cheers, Ed
1. People, in the exact posture, clothing, and colors you want. I have few on my layout bacause they all look phony. The guy above with the drums looks like he's pushing a heavy lawnmower more than an empty dolly. And few have hats because they are too thick when molded. Hats back in the day were on every head. That's a big advantage of 3D: thin stuff without flash.
2. Cinder blocks. I bought several bags of them in HO but spent hours sorting good from bad. Too thick, too much flash, out of scale, etc. Plus they were white.

For those interested: Kathy Millatt shows how she used Autodesk Fusion to design and 3D print some oil drums in resin in this 3 part series on MR Video Plus. Here's the link:

How about 1/12 size models of old Lionel Standard Gauge equipment to run on Z gauge mechanisms to be used in doll houses??
Edit: Make that 1/8 size models. Z gauge of .256 scales out to about 3" gauge in "doll house" of 1/12. "Standard" gauge trains have a gauge of 2-1/8". I feel that such trains would be better proportioned to track size than to "environment" size unless they were unpowered.
mbinsewiJust kinding! your work is beyond excellent.
My work? Naw, those are just stock photos from the Faller site, Mike.
I do have a passion for machinery and related tooling but I'd rather not clutter up this thread with all that. I'll save it for WPF or "show me something" threads.
Still — thanks! Ed
Those are great pictures Ed, but I think you need to get some of that carbon black and give the area a dusting.
Just kinding! your work is beyond excellent.
As far as the 3D printing, I want my dry bulk trailers! There is more than enough 30's, 40's, and 50's stuff to go around already!
Mike.

PeteVSThanks!! That's what I was looking for!
The link I posted earlier shows a shaper, they have a lathe, too, perhaps they offer more by now?
"Mass-manufacturers are beginning to embrace the technology. Here is an HO machine tool made in 3D plastic from Kibri:

PeteVS Before I retired (10 years ago) I was doing 3D modeling on ProEngineer. That was some mega-software. What are hobbyists using for 3D modeling? What hardware is needed to run it?

There are a number of free-for-hobbyists CAD tools available that will run on any PC, and will benefit from improved graphics cards and faster processors if you have them.I liked using Sketchup Make, but Trimble has phased it out for a pricy paid subscription model and a free browser-based version that's lacking in many of the features that made Make appealing (especially a photo matching tool that let you import perspective photos of buildings, trains, etc. and easily derive unknown dimensions from one known measurement).That has had me looking into Fusion 360 like Harrison recommended, (which I believe is free even for commercial use if your company grosses less than $100k/yr ), as well as OnShape (https://www.onshape.com/products/free), which is fully browser-based and saves your work in the cloud, and is free for non-commercial use. Despite its reputation as a toy, I know someone who designs and sells highly-detailed HO traction models on Shapeways using Tinkercad https://www.tinkercad.com as the modeling tool.
"Atlas has a line of 3D printed accessories:"
I checked the Atlas offerings. With the exception of the propane tanks, the other items are offered by other vendors in injection molded parts. Recently I saw a post somewhere for 3D transformers and electric motors. The prices weren't outrageous, but the finish was poor.
I am using Autodesk Fusion 360, I can get it for free as a student.
How about some machine shop equipment such as a medium sized lathe, drill press, work bench with a vise, and a Bridgeport milling machine?

Wow Ed- I imagine that would take at least $20 in Plastic!
I just ordered some cheap(china) filement, I think I will try making some Alco and early GE engines, and maybe cast some. I like the forklift Idea, That is something folks at shows might like.
Thanks, Dan!
Those will fit the bill nicely
The first time I saw a 3D printer was on TV making the prototype of a product. The 3D printed object was then used to create the mold for mass producing the item. The second time was in the movie Jurassic Park 3 where they printed the sound box of a raptor. The first time I saw one in person was at a robot convention. They were using it to print parts to build more 3D printers. There were no mass produced 3D printers that you could buy at a store yet, but you could buy one from this company. A few months ago I found an item on Sharpways that I didn’t like so I sent a message to the creator and he made changes in it for me. That might be one of the best things about 3D printing. You can't do that with mass produced molds. Anyway how about some interior details for diesel locomotives?
M-Wellll-now!
There's that expression be careful what you want because you'll probably get it.
I was parusing ALCo diesels on ebay, and came across some 3D printed prime movers. Not just one, but THREE different sets of the ALCO 251 diesel, in V-8, V-12, and V-16 versions. Each set comes with a complete built up engine, and a bare stipped down block (crank case)
They also have EMD 710s (modern) in 16 and 20 cylinder sets.
Here's a link below. I ordered a set of Alco 8 and 12 cyl engines and I'll let ya know how they look when they get here. I'm not affiliated with the seller. Dan

Thanks, Dan.
I check in at Shapeways every few weeks to keep up with what's new.
Ed, Yes, I already just bought a pkg of those Keystone diesel details on eBay. THEN discovered there's what looks like a VERY nicely detailed traction motor with axle and wheels at Shapeways.
Excellent job on those stripped locomotives! (I like your scenery too) Dan
There is sooooooo much stuff out there now, on Shapeways, and from all of the sellers, and all of the individuals that do printing, you would be hard pressed to view it in a day.
Good luck to the OP.
My son-in-law made me some 40' containers on his printer. I have an N Scale layout. I could paint and detail these containers and save the $7 - $12 expense for the many containers I need for an intermodal train.
While I wouldn't spend the money to buy a printer at my age, I have purchased several items.
One of the best things I got was a radio tower that would have taken me weeks to build.
One thing I have found, but have not purchased, are some modern 3-D semi trucks and trailers. Those of you in N Scale know that these are difficult to find, and the ones available are expensive.

I'd like to see a roof top water tower smaller than the Walthers.
