You may not have yours on hand, but you get a nicer quality with some dual printhead action

What drafting software does your set up use?

Honestly I haven't taken a look at all the different software used for operating it yet, been mostly focused on building, aka I don't know. lol.

Well, it's fun that somebody else is working on this too. I am looking to develop items for tanks that are in demand but notavailable Track links come to mind, but I'm not up to speed on this thing yet.

Just got an e-mail... they are printing the oildrum and padlocks today. I will post pix when I can.

I think track links and roadwheels would be good start, along with small detail items. I have been contemplating turrets, but I have been wondering how well they would print with a hollow interior, plus I am not a good modeler. I assume they would need significant support depending on it, not to mention cleanup of the ridges afterwards. I did hear you could just put ABS into acetone for 1-3 minutes and it would do the trick without damage though.

Those printers will shine where simple prototyping is needed. I can sculpt a human, but a K98 needs a lot more attention and time. Once printed, the piece could be cleaned up and copied like anything else.

Engine deck grates and the like take forever to scratch build because the eye looks for consistency. Just like machine built zim looks odd, hand built grates do. Very hard to pull off with an X-acto, easy with a computer.

If I could find copies of the old shop drawings for the track links I could reproduce them in 1/16 scale. Once I made one good ABS link, a rubber mold can be made to reproduce them in resin. For metal links the rubber mold can be used to make wax track links for metal casting using the lost wax method. One good example to start with and away we go!

If you get far enough to make a workable link, it would be best to draw up a parts-tree that you can incorporate a length of them for molding. I could help you in terms of what you'd need for resin, but have no idea for sandcasting/lost wax. I did a bit of research a while back on metal, I think bismuth had the lowest melt and toxicity, but there were so many options, it seemed best to farm it out.

Shapeways prints in 420 Stainless. It's $8 a cubic centimeter and is actually glued stainless dust sealed with bronze. There's a track link in there somewhere, but I'd have to look into their requirements, it seems it has to be 3mm thick.

You pay only for material used, I could figure out the volume of a Pz III link and go from there, but my guess is not too many links for $8. []

I used to be a jeweler, I have cast silver and gold before.  My only worry is drilling the pin hole consistently.  I would need to build a jig to hold it while I drilled.

Shapeways can do some nice quality prints,can have huge build sizes, and tons of materials to boot.

That's good to know, the jig would be relatively easy unless you are talking ramping up for production.

I almost pulled the trigger on one of Theo Jansen's Strandbeests from Shapeways a few times. I still might.

http://www.shapeways.com/model/24711...-parvus-7.html

It comes out of the printer like that, no assembly required.

Could you cast the track pins in to make consistent holes?

No. The heat would take the temper out of the pin. I could cast them with holes but they would need to be cleaned out with a drill anyway.

Signing on. I don't have any rc tanks. My experience is limited to full size M551s, M60s, and M1s.

The way the weather has been around here, tho, I might just get into RC tanks. If I can find one heavy enough to not get knocked around by the effing wind like my planks and helis. Either that or I'll totally cave in and get a sail boat.

Martellus I am truly jealous of your purchase. I'm thinking about getting one too. I'm kinda a CAD nerd anyway. I hope you share some pic's of your printer while you are building it.

I usually speed through anything I get and forget to take pictures, but this is an exception. Here is my progress so far:






Printer frame, Y axis stepper motor just installed.



Heated PCB and printbed with marks for drilling tommrow.



The desk with various items and stuff to be done.



You may be jealous of this, but I am always jealous of your su-100 and your awesome co2 airsoft system. So we are even

Also, anything in white plastic is actually printed, by another 3d printer. The goal of the reprap series of printers is eventually to get a fully self replicating system.

I for one are glad for the exception.

It's a treat to watch the assembly. Looks like they provide nice directions.

Slow day, mostly fault of my own mistakes, but I got the stage on and the X axis and Z rods in place.

Late night update. Extruder done and mounted.

They just sent me a picture of my 3d print project. It is still coated with the support material but the orange stuff is my fuel drums. I will get to hold them in my hand next week.
