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 ….

How Much Would it Cost to 3D Print These World-Famous Landmarks? [Infographic]

Much is known about the capabilities of 3D printing. From living body parts to high end dining, researchers have developed ways to print a mind-boggling array of objects in the third dimension. But just how far can scientists and tech fans push 3D printing, and could it be used to print buildings, landmarks and other massive objects?

To find out, we tallied up the time and cost of 3D printing the world’s most celebrated landmarks, as well as other structures you’ll no doubt recognize.

3D printing world famous landmarks - TonerGiant

Whether you want to erect Big Ben or the Eiffel Tower in your back garden, it seems 3D printing has a long way to go before it replaces traditional building techniques. That said, 3D printing technologies are emerging at an extraordinary rate, with new variations of the technology hitting the headlines every other day. And with each ground-breaking new development, surely we’re one step closer to printing our own pyramids, Death Stars and star ships?

Don’t forget, the above calculations were based on printing from a standard household 3D printer. Use a 3D printer like this one, and we reckon you could have your own Hogwarts in a fraction of the time – especially if you had two or three of them.

Sharing 3D-printing possibilities

Some artists hold their processes close to their vests (where did that expression come from? Who wears a vest anymore? Sorry – mind wandering ….).

I’m not one of them.Arizona Artists Guild logo

I have a large and active YouTube channel with more than 450 videos in which I share metal fabrication and 3D-printing tips. I also have held many events for other artists at my studio and at my home, where I have my 3D printers (the studio is just too dirty – I make dirt there!). I’ve even held events for other artists at my art shows.

So when the Arizona Artists Guild asked me if I’d do a program for the organization’s sculpture group, of which I’m a member, I was glad to do it.

But this time, I decided to do it a little differently ….

Try, try again with 3D printing

I just can’t help myself.

3D printed Farkle board - Kevin CaronSometimes I just get an idea in my head, and I have to follow it through. Fortunately, 3D printing makes that easy. (Well, easier.)

In this case, it’s that Farkle board that I have come up with yet another design for. The one at the right was my first attempt, which came out pretty well. The black field you see, though, is cloth I added later. That means having to cut it exactly right to fit and gluing it in without dripping glue on the PLA board itself.

Being around or using something always helps me understand it better, or see a better way to design or use it. (That’s why I like to bring home my sculptures – living with them helps give me a new perspective and, I hope, appreciation for them.)

My buddy from the service and his wife were in town recently, so we had a rousing couple of games of the dice game Farkle, whereupon a new design popped into my mind ….
