Home printing quality is improving all the time.

I have a friend in the UK who is printing some of my designs and reselling them on eBay.
He started with a $200 printer and improved it himself as well as trying different techniques.

His latest product is this little diesel switcher in On16.5 (British On30).

Done as a flat pack kit he is selling it for £15 -
would be about £50 on Shapeways.










I'm currently working on a BO-BO centercab version for On30.

Sean, that looks like real good prints.

What about the quality of the print concerning the bolt and nut detail?

Could make a sharper closeup of it?

Sean: 

Thanks for starting this thread. 
It has got this old guy thinking about this again. 

I model in 7/8's and would like to print truck side frames. 
Is the material strong enough for this or must one use a stronger material (nylon, polycarbonate etc). 

The work you are doing with the flat cars is lovely. 
Looking forward to more.

Dick

Printing in ABS or HIPS is fine for truck sideframes even in 7/8ths -
I've only done G scale so far, but I can't see any problems arising from going to 7/8ths.

I would suggest doing a separate bearing though, I use tophat ones printed in nylon at Shapeways -
3mm inside, 5 mm outside, but you can use brass or even ball bearings.

Have you got a printer yet ?
I can resize some of the G scale ones and send you a file to try if you want.

Tom

Thanks Tom, 

So far just looking at some, very confusing.
Like what I see in the Enders universe. Also the Tevo Tornado looks good. 

Yes I would appreciate the file. 
I have no intention of ever using any of this for anything other than my own enjoyment.

Thank you.
