Video : Formlabs Releases New Resin TOUGH!

So i received a email today telling me about Formlabs new resin TOUGH!  It looks like it currently only comes in one color, a cornflower blue semi-translucent resin.  It is supposed to be tough, durable, and used in a variety of ways where ABS is normally used.  From the video and the gif below, the results are pretty impressive!

However the sticker price for 1L is the shocker, $175.00!!  More expensive than any of their other resins!  I'm not sure this is a good thing as other companies are producing similar (normal) resins at a fraction of the cost, and its only a matter of time before a similar (tough) resin can be had for cheap.  
I guess this is similar to Makerbot vs other fdm manufacturers, the highly visible company has to charge a premium for their "brand" even though its the same chemicals in the end.  

But if people pay for it, who am I to judge?  For me personally I'll shop around for a better price, or dare I say attempt to create my own! :)  

Hope you enjoyed this post and thanks for stopping by!

Hot Glue Can Save Your Failing Print, Maybe...

Over at Make Andrew Terranova shows how using a little hot glue on a failing print might be all you need to save it!  

Essentially the print was skipping a few layers so he added some hot glue and the print was saved.  Head over to make and read his article  about how he came up with the process and how he uses it to save some of this failing prints on his 3d printer.

I like the idea and for one I plan on using the technique myself if my print starts to fail... great work!

Hope you enjoyed this post and thanks for stopping by!

3D Printing : Cold Vapor Smoothing

you can click on all the pics for larger views!
So I've been working on this Nexus 7 w/Battery Charger Holder/Stand (Prototype) which originated with this model on thingiverse http://www.thingiverse.com/thing:355918 .

Its an ok design, but the cable goes out the side instead of straight back, the stand itself slides around unless affixed to a surface even with the battery in the mount providing a bit a weight, and the magnet is so strong between the charger and the nexus7 that more than often the charger puck gets pulled out of the stand.  Not to mention that as presented its almost impossible to print on some printers.

So I took the design and tweaked it, I separated it into two sections so any printer can print it, I also placed in a small divot in the back of the charger area for some velcro or adhesive strips, as well as divots on the bottom to hold the stand in place on a surface, and included a "spinner" device so you can orient the viewing angle. 

However this post is really about the "finish" of the stand.  Being that I'm using ABS plastic which "melts/dissolves" in acetone you can use a process called vapor polishing to give your products a injected molded look. (You can't use acetone with PLA or other similar plastics, each plastic usually has its own chemical that similar effects can be achieved however some of those are really nasty compounds and I'd avoid using them in a process like this.)

There are typically two methods to do this and both are similar, one method uses added heat to hurry the vapor process and "melting" of the plastic along with a breif stint in the freeze of the object you want to smooth before you put it in to the hot vapor path.

The other method is using the same process minus the added heat and stint in the freezer.  This is the cold process
