3D Printing Filament Comes Out of the Closet

The Point, a 3D-printed bronze sculpture - Kevin CaronI’ve written about applying finishes to the surface of a 3D-printed resin sculpture, but today there are a lot more options for types of the resin filament itself.

Nearly everyone has heard about exotic 3D printing that use biomaterials, titanium, etc. but I’m talking here about filament that mere mortals like me can use in their own 3D printers.

I have 3D-printed in bronze, as you can see at right in my 26″ tall sculpture The Point. That filament is 80% bronze and 20% resin. I’ve printed both a small version of this form on my Cerberus 3D 250 and the larger version on my 8-foot-tall Cerberus 3D Gigante 3D printer.

I don’t have as many choices for my Gigante, though, which requires 5-pound spools of filament for my large prints – unless I want to “weld” together filament from 1-pound spools – providing I can get 3 millimeter filament in that type – and rewind it , which isn’t an entirely crazy idea.

Yet the new materials you can actually print in are staggering. And they aren’t just facsimiles, either. The filaments are actually a mixture of the material and resin, so you are literally printing in these amazing materials ….

Let there be light (with 3D printed translucent filament)

Sunscraper, a 3D printed contemporary art sculpture - Kevin CaronIn February during my one-person show devoted to my 3D-printed sculptures, I heard many interesting comments and questions.

One thing I was asked repeatedly is whether I’d ever put lights into a 3D printed sculpture.

This undoubtedly grew out of them seeing the luminous translucent filaments I’ve used, including ice blue (for the sculpture Easy In), red (several sculptures, including Redhead and Love and Marriage), purple (Twin Peaks and Love and Marriage) and – my favorite – yellow (SunScraper, right). The yellow just really lights up!

BTW, I’ve tried green “translucent” filament, too, which wasn’t really translucent and was, honestly, just pretty ugly.

The subject came up so often, in fact, that, of course, my mind got going ….
