From biodegradable filaments to a new 3D paper printer, there was plenty to see at the Inside 3D Printing show last week in New York City.

3D Printing demo stations always have some intriguing printed objects to catch your attention. These models at ProtoCam's table were no exception. It turns out they offer more industrial solutions than printing tech for your average maker, but the glitter and transparency got my attention.

NV Bots 3D printer

NV Bots was showcasing its uniqueness to the 3D printing world: It has a blade that can automatically remove your printed piece so the next piece can begin printing. Presuming a human -- or a robot -- is on hand to remove finished pieces from the chamber before it gets too full, you could have this machine print out countless items from a queue.

'Environmentally friendly' filament from ECOmaylene 3D

Here we see a new "environmentally friendly" PLA (Polylactic Acid) Alloy filament from ECOmaylene 3D out of Singapore. Because it's made out of corn starch or sugar cane, it's biodegradable: It's supposed to decompose within two years of hitting a landfill.

Refillable spool from Titan 3D

Another green-thinking solution on offer was the refillable spool from Titan 3D. You can order precoiled refill packs that slide right onto the old spool, and never have to throw away that piece of plastic when you restock a color.

AccuSmooth 3D Printed Part Smoother

The AccuSmooth 3D Printed Part Smoother is a vapor tank you can dip your 3D-printed objects into for a few seconds to get a smoother finished look. The vapor melts the surface of your object just slightly, eliminating the layer lines.

The Mcor Arke printer uses stacks of paper, which it will cut, glue together in a stack and print color onto, creating finished objects with very little weight.

Doll dresses made by 3D pen

And finally, I had to get a picture of these doll dresses created using 3D pen. This is exactly the sort of toy I would have loved to play with as a child. With the specialty filaments from eSun your child can dissolve and reuse the materials if they don't like what they made.
