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 →

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 ….

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….

3D Frankenstein: Gigante 3D printer gets a new brain

When I commissioned the creation of my 8-foot-tall Cerberus 3D Gigante 3D printer 3 years ago, I knew that the technology would change.

Of course, technology changes all the time, but in the fast-moving field of 3D printing, it changes as fast as you can type.

As chronicled in this blog, Cerberus 3D “mad scientist” and all-around cool guy Steve Graber and I made a lot of changes in the Gigante as we worked through the issues that arose when using the printer. Software, hardware and filament all demanded tweaking, and finally we got the Gigante running well.

There were still issues, though. The biggest was a tendency for the print to just … stop. The printer would freeze, and the computer would join it, stuck in some sort of limbo while I pulled my hair out trying to figure out why I’d just lost yet another print.

Sometimes it was simply that the computer, which is dedicated to running the Gigante, decided to update. I dealt with that by always firing up the computer well before I started printing. OK, that worked most of the time.

Finally, though, it became clear that the processor just wasn’t handling the information fast enough ….

Art takes 3D printing seriously at ASU

3D Systems ProJet 660 3D printerOne of the strongest intersections of art and 3D printing is taking place right here in Phoenix at Arizona State University.

I first encountered Dan Collins, who is a professor of Intermedia in the School of Art as ASU and a co-director of the PRISM lab, an interdisciplinary 3D modeling and rapid prototyping facility.

Dan has been involved in 3D printing for a long time. He was involved with TeleSculpture, which was held in 1999, 2000, 2001, 2003, 2005 and 2007, in which artists would simply send in their designs, which would be printed remotely for the show, an incredibly innovative idea, one certainly ahead of its time.

(You can read more about Dan’s activities and involvement by clicking on his name above.)

What Dan and his team have done is amazing ….

‘You have to do what?!’ – Barriers to 3D printing

Using CAD to design - Kevin CaronAlthough the buzz about 3D printing isn’t as red hot as it was, people are understandably still jazzed about this transformational process.

I see the reactions all the time, whether it’s at a gathering focused on how the process works, how I use it in my practice as a sculptor, or just a bunch of people who are fascinated by 3D printing. What I almost also invariably see is disappointment.

The dirty little secret about 3D printing is that you must have a file that you can print.

That’s easy enough if you are satisfied printing other people’s files, such as ones downloaded from Thingiverse. But what if you want to create something yourself?

Well, at this point in the evolution of 3D printing, you’d better know CAD (Computer Aided Design) software, or know someone who does. That’s what most people don’t realize: 3D printing itself is the culmination of a longer process ….
