The greatest weapon in the 3D-printed gun debate is FEAR

3D printed gun partsAny time I show my 3D-printed sculptures or jewelry or have a 3D printer running at an event, I inevitably get asked about 3D-printed guns.

It’s exasperating, because the fear of these guns – which is currently unfounded – taints 3D printing.

This topic has come up before, but it’s back in the news as the people who want to put plans for 3D-printed guns online are back at it.

I cannot explain or understand why they think this is a good idea, and I’m someone who has owned and used guns, so I’m not a gun-hater by any means.

There is just a time and a place for everything, and this issue is frustrating on many levels, not the least of which has to do with 3D printing itself.

As I explain to people who ask – so we can get back to discussing all of the wonderful things 3D printing can do – most mere mortals, like me, cannot afford a 3D printer that can print in metal…. Read More →

A rainbow of colors comes to 3D printing filament

RAL color wheelI originally began working in wood (OK, in cars, if you want to go back further). I didn’t do anything professionally with it, but I built some furniture.

Then I turned to metal, which has been the bulk of my practice since I began selling my artwork in the early 2000s.

About 4 or so years ago, I began playing with 3D printing.

Now I work with metal during the day, and 3D print in the evenings and on weekends, having fun with various filaments and forms along the way. I’ve sold a number of 3D-printed sculptures, the largest of which is 5-1/2 feet tall.

It’s been amazing to watch 3D printing evolve so quickly, and to see intersections between my metalworking and 3D printing worlds. Now another intersection, or blurring of the lines, has happened, and this one is a big deal ….

Combining 3D printing filaments

MatterHackers PRO Series Flex 3D printer filamentMatterhackers Taulman Black T-Glase 3D printing filamentThe more I work with 3D printing (and, well, anything I do), the more questions bubble to the surface ….

   Can I make the material do this?

   What if I do that?

   Do I really need to ….

A lot of times, things work out. For instance, I did a  couple of videos about welding copper and steel (yeah, it worked, but I wouldn’t walk on a bridge welded that way).

Sometimes, not so much (I once filled cuts in a steel bell with copper, only to find out that oxidation was not kind to it).

That brought me to my latest wild hare chase, which is to combine 2 different types of 3D printing filament in a single print, and what the heck, I think I’ll throw in some sand, too ….

3D-printed sculpture storms Tucson

A visitor to the Sculpture Tucson art show watches a Cerberus 3D 250 3D printer printing - Kevin CaronOK, maybe I went a little overboard in the headline, but I’m still really jazzed at the reception of my 3D-printed sculpture at the recent Sculpture Tucson show in, yes, Tucson, Arizona (is there another Tucson? Hmmm, I’ll have to look that up ….)

The turnout at the show was incredible. Preliminary estimates say that 4,300 people came through in just 2-1/2 days April 6 – 8.

Although the show was outside at Brandi Fenton Park, I had my Cerberus 3D 250 running the whole time. Amazingly enough, it only failed once when the wind got the best of it, but overall, it performed beautifully.

It also fascinated people. A few people who came by knew about 3D printing, but most visitors had never seen a 3D printer running before. That meant I did a lot of education, which is how it usually goes when I have the printer running at an event.

We actually apologized to the artists around us, who had to hear the spiel over and over and over again. The challenge was always explaining it like I’d never said it before, but what I would say seldom varied (“… start in CAD …” “… the filament comes down from here …” “… like a big glue gun …”) ….

Getting it together: connecting 3D prints

Untitled 3D printed fine art sculpture - Kevin CaronEven though I have an 8-foot-tall 3D printer that will print up to 4 feet tall, there are times I’d like to make something bigger.

I have done that, as evidenced in the 5-1/2 foot tall sculpture Epic Swoon (below), which was commissioned by PriceCooperswaterhouse in Columbus, Ohio. That sculpture, the tallest 3D-printed piece I’ve made to date, reached its height by placing the main part of the sculpture on a black pedestal.

In all honesty, I have not had much luck yet in matching parts so that they can be put together seamlessly, so the contrasting pedestal was a handsome workaround.

Recently I created another sculpture (right) – well, at least the start of one – by printing 2 sections and sliding them together using slots. The fit is tight and requires no adhesive, but it wouldn’t hurt, either.

So it’s no surprise that Pinshape‘s recent post about using adhesives for 3D prints caught my eye ….

Alien forces invade 3D print

As-yet-untitled 3D printed sculpture - Kevin CaronCrazy things happen with 3D printing, especially with my 8-foot-tall Cerberus 3D Gigante 3D printer.

As Steve Graber, who built this monster, has said, whatever this printer does, it does spectacularly. That definitely includes surprises like the “slubs” on my sculpture Love and Marriage, which are explainable, and recent moments like the time the print head decided to print a foot to the left of the print bed.

The most recent and as-yet-unexplainable oddity – or, as it’s called in the art world, “artifact” – is what it did to a print I just finished ….

Switch cuts out 3D printing problem

3D printed table base - Kevin CaronAbout a week ago I decided to tackle a project I’ve been thinking about for a while. I have a beautiful glass tabletop and thought it would be fun to 3D print a base for it.

Fun?! I like to go into a project thinking positively, but maybe that just set me up ….

Anyway, the first day of what would be a 5-day print went fine. It was when I had to change out the 5-pound spool of PLA filament on my 8-foot-tall Cerberus 3D Gigante 3D printer that things went terribly wrong.

The print paused normally, then I switched out the spool of natural filament and loaded up the new spool. When I tried to resume the print, though, everything went haywire. The printhead swung wildly out of position, and the print was lost.

I was ready to pull my hair out! A whole $100 spool of filament and a day of 3D printing had been lost. Not to mention the frayed nerves.

Then Steve Graber, the man who built the Gigante, told me about the switch ….

Seeing in 3D – Using 3D printing for prototyping

3D printed stem of Schubertii sculpture - Kevin CaronWhen 3D printing first became popular for more general use – it’d already been around 20 years in industrial and scientific settings – “rapid prototyping” was the buzzword you heard everywhere. (After I started working with 3D printing and especially my 8-foot-tall Cerberus 3D Gigante 3D printer, I found this hilarious – there wasn’t much rapid about it.)

While I do create sculptures using 3D printing, I also use it for protyping. It’s really important when I’m creating a sculpture in CAD and then actually building it in metal to be able to see all aspects of the form.

A great example is a sculpture I’m just beginning, Schubertii. Based on the plant by the same name, this sculpture will be 12 feet tall. Seven feet of that will be the sculpture’s “stem.”

The stem is fairly simply to look at, but creating it in metal is going to be, well, challenging. Its round edges and flowing form will require me to use a combination of tools – air shaper, English wheel, maybe even the slapper (yeah, there really is a tool called a slapper) – to get the rounded form that is the opposite of how metal comes, in flat sheets.

To get the form right, I printed the stem maquette, or model, on my Cerberus 3D 250 desktop 3D printer ….

The mystery of the 3D print fail

Overheat screen for 3D printer - Kevin CaronIt starts out so innocently …. Doesn’t it always, especially with 3D printing!

I wanted to print something using NGen_FLEX (usually called “Ninjaflex”) rubber filament on my 8-foot-tall Cerberus 3D Gigante printer when I got a “Runaway temperature warning” (right), and the printer shut down.

I checked the graph in Simplify 3D, the combination host and slicer program I was using, and saw the temperature spiking instead of its usual gradual climb.

I shut off the 3D printer, let it cool, and tried it again. Same problem.

I printed the same file with regular PLA and had no problem.

There was only one thing to do …

Tinker time for all ages: event turns on young and old

3D printing at Arts & Technology event in Surprise, AZ - Kevin CaronWhen you’ve done something for a while, you start to take it for granted.

There’s nothing like talking to others about 3D printing – and, best of all, showing it to them – to remind me how remarkable this technology is for many people.

Recently, my wife spoke with a woman who had never even heard of 3D printing. That’s pretty mind-blowing.

Most of the people who attended the inaugural “Technology & Art: A Tinker Time For All Ages” on Saturday, October 21 had heard of it but never seen a 3D printer in action.

They have now….
