Paul,

What are you thinking about having printed? Parts? Shell?

I might be able to help if you just want parts.

I would ask Mark Dashnaw

If I wanted to have the cad work done for A Southern Pacific SD9 that would be suitable for 3D printing, who should I go to?   I'm really not interested in trying to learn it and do it myself.  Might be kind of a loaded question,  but I need to start somewhere.  Two or three SD9's are on my bucket list.

Ever since I began 3D printing at my library, I have used Tinkercad.  It's easy to pick up because of its graphics-based approach.  It's free and online, so it doesn't take up space on my computer, and Tinkercad keeps all the designs on their computers.  It is pretty flexible, but doesn't do curves as simply as I'd like, and doesn't do things to scale (you can't make something 15 feet long in 1:32 scale, you got to figure out what that is).  I've made things as simple as a sign, or as complex as a craftsman house, also windows, doors, and load covers to hide batteries and remote controls.

I just wanna know which Can Bus I should interface with to the micro brewery on Eric's layout. I found the pizza oven line so that is a good start for me anyway!

Has anyone ever considered sharing the LCC CAN bus with other CAN bus systems? (my Zimo uses the CAN bus).

 

Greg: this question has been on my mind, and I finally had a chance to test it out.  I hooked a Linux machine up to the LCC bus using a generic CAN-USB interface (I use these for car hacking) and fuzzed the bus with random CAN frames.  The LCC communication still worked fine.  LCC frames use extended (29-bit) arbitration IDs, so I think if you dump standard 11-bit ID frames onto the bus, there won't be any chance of duplicating a valid LCC message.

The only real limitation is the bus speed.  LCC operates at 125 kbps.  There are several other standard CAN bus speeds, so you'd have to find out what Zimo or whatever else uses.

Unpainted plastic usually glows in bright light. So paint is rather necessary to make the model opaque. I don't know about your printed containers, maybe that plastic doesn't glow, but most plastic does.

Is the green your filament … could you print with diff colors so you would only have to paint details ?

Yes Sean, the green is just filament.  I'm sure I could get away with not painting but they should be painted for UV protection anyway.  They will certainly need weathering.

Dan, Very nice print and paint job. I'm amazed how well the rods came out! Definitely difficult to accomplish.

Are you printing at 0.08mm or finer? You really have your machine dialed in!

John R.

The Doors and frames .1mm.  Everything else is .2mm  using a .4mm nozzle.  The model has not been painted yet.  It's just matte green filament.

are you going to be selling them?

I currently don't sell any of my designs.  I just share them for anyone who has a 3d printer.  I've enable the printing apps on the Thingiverse page so you can get a 3rd party to print the parts for you.  Just click "Order this printed" and choose a service.  I would recommend Treatstock as you may be able to find someone close by and save on shipping.   Make sure you order the correct amount of each part.

Effective use of 3D printing, Dan.  Especially looking at the prices of commercially available containers. 

I've been looking to do this for a long time.  My original idea was to just print the ends and mill the sides and roof from PVC sheet with my 90% built CNC.  This will do for now.

Very nice. Print once, cast in resin perhaps?

Almost 2 days for a container? Gee.......

I could probably cut that down a bit but for good bed adhesion and quality I'm printing at 40mm/s.  Of course it's not really taking MY time as I am sleeping, working etc. while it prints.

Looks great, Dan..  Using the outside faces for stacks should be cost and time effective..    

A guy on Thingiverse designed a European flat and I really liked his container so I've re-scaled it for 1:29.  https://www.thingiverse.com/thing:3894100

So now I can make 40' containers for about $9.50 each!   Downside is it takes 43 hours and 17 mins to print one!  I plan on making a stack of them so I will only need the outside faces.
