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….

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 ….

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 ….

3D Printing Contributes to Evolution of Form

Limoncello Prima, a 3D printed fine art sculpture - Kevin Caron

Sometimes I just start creating, as I am doing with a metal sculpture in my studio right now.

Sometimes I design in CAD (which is how I got into 3D printing in the first place!) and then create the form in metal or resin.

And sometimes a sculpture evolves as it is created. That’s exactly what happened with a recent artwork, 50 Years of Limoncello.

Well, it really began with a call for an art show in New York. The show, “The HeART of Italy,” celebrates the spirit, history, people and places of that romantic land, where I spent time a couple of years ago.

Thinking about my time in Italy, I decided to use some of that luscious translucent yellow PLA filament to create a sculpture to submit to the show.

What I didn’t anticipate – but surely embraced – was how the artwork evolved. But then, that’s part of the beauty of creating art ….

 

I first printed a form that, as many of my sculptures do, celebrates the female form. After looking at it, I decided to use the same filament to create a more, shall we say, lusty sculpture.

But when I placed the two forms together, I began to see something else, an artwork composed of three forms. I decided to 3D print yet another sculpture, using the same beautiful yellow filament and the same basic design, but making it noticeably more slender than the other two.

The result is something that some in the art world might question (but what else is new about my work!), but that came together beautifully, simply because I followed my eye, my heart and my intuition.50 Years of Limoncello, a 3D printed fine art sculpture - Kevin Caron

The sculpture, 50 Years of Limoncello – that drink is one of my warm memories from my trip to Italy! – features three sculptures that, together, share the evolution of many of us who indulge in the pleasures of life. Each sculpture – Limoncello Prima, Limoncello Mezza and Limoncello Troppa – can stand on its own, yet together they create a story.

Now let’s just hope that the judges in that New York show love this piece as much as I do!

 

Surprises selling 3D-printed sculpture

Three of my large format 3D-printed sculptures at Vision Gallery - Kevin CaronI got great news this week when a check arrived from one of my retailers, Vision Gallery in Chandler, Arizona.

Vision has been carrying my work for a while, and for the past many months they have displayed the largest collection of my 3D-printed sculpture outside of a special show I did this past February. With glass walls on three exposures, the gallery is the perfect place for 3D-printed sculpture, especially light-hungry translucent pieces.

I wasn’t surprised that the sculpture they sold this month was Lemon Drop (shown on next page), a particularly luscious piece printed in translucent yellow PLA filament. Of all the translucents I’ve used thus far, the yellow is by far the most beautiful. It seems to capture and reflect the light.

The blue translucent is downright cold, although still beautiful, while the red tends to glow. The purple is more subtle, as evidenced in Josephine, a sculpture I recently completed that is on display at Vision Gallery. I love the emails I get from the gallery manager, who keeps snapping and sending photos of the sculptures as the light moves across the sky. She’ll write such reports as “Miss Josephine looks particularly sultry today.” That’s music to my ears: it means the art is as alive for her as it is for me.

What has surprised me, though, is who is buying my 3D-printed sculptures ….

Stick this! Adhering a 3D print is key during printing

3d printing-lifted corner - Kevin CaronOne of the challenges of 3D printing that I think – knock on wood – I’ve finally worked through is adherence to the print tray.

There’s nothing more frustrating than having a 3D print come loose from the tray while a print is underway, and it’s something that’s happened to me far more times than I even like to think about.

The Cerberus 3D Gigante’s large format prints are particularly prone to this problem – I have a few large prints the corners of which have “flipped up” slightly because they cooled faster than the rest of the print. See an example to the right – fortunately in this case, it works with the concept and theme of the sculpture!

Sometimes, though, a lifted corner ruins the print altogether.

Other times, on any of my printers, a 3D print simply comes loose from the print tray – then it’s game over.

But I’ve learned a few things and updated some to improve my quality and finish rate ….

 

My 3D Systems CubeX came with some sticky stuff that I used on that 3D printer until I got my Cerberus 3D machines, when I learned about using hairspray. Yes, hairspray. (I’m sure they wonder at the grocery store when I buy three or four cans of Suave Extreme Hold hairspray. I just smile.)

Suave Extra Hold Hair Spray - 3D printingI still use hairspray – more on that in a moment – but I’ve gotten away from using blue tape. That was the other trick I learned when I got my Gigante. I’d apply painters’ blue tape – the kind that is supposed to release easily – to the print tray, pressing down just as hard as I could. It worked sometimes, but not always. Also, not all blue tape is created equally, apparently.

I don’t like the blue tape because

  1. It is hard to get off the tray
  2. It’s especially difficult to get off the sculptures
  3. It doesn’t always seem to work.

What seems to work best is a heated tray. That’s why I added one to my CubeX and another to the Gigante. 3D prints adhere much better with heat! I don’t think I’ve had a problem with large format prints lifting up since I installed the heated tray on the Gigante.

Of course, you don’t just use heat. Before I start a 3D print, I also clean the print tray well, then spray it liberally with hairspray before I start printing.

Of all the challenges with 3D printing, I think – THINK – I have this one licked.

What I don’t need to do when 3D printing

Artist Kevin Caron standing beside his Gigante 3D printerDuring my recent art show when I had my Cerberus 3D Gigante 3D printer running, several visitors asked whether I just pushed “go” and walked away while printing.

After I finished laughing, I’d explain that running this printer is like having a 3-year-old. You can never entirely take your eye off of it, and sometimes it requires extra care, other times it needs discipline. (I haven’t spanked yet, but I’ve sure thought about it.)

All of that is to say there is plenty to think about when a print is under way.

A few months ago, my business manager asked me if it would make sense to keep a log of my prints. For instance, she thought maybe I could note when I started the print, when I changed spools, etc. I could even track when I turned on the fan, what speed I was running at for how long, and other such details.

“That’s probably the last thing I want to do!” I replied ….

Aesthetic tweaking with 3D-printed designs

Daisy Mae, a 3D printed fine art sculpture by Kevin CaronWorking with my 3D-printed sculptures requires a balance of aesthetic and technical considerations. In the big picture, that’s not all that unlike working with metal, but the way I do it is definitely different in each medium.

Take my latest 3D-printed sculpture, Daisy Mae (right).

As usual, I began playing with forms in CAD, this time in Rhino. It took a couple of tries to get it to print properly – there were some hiccups with adherence to the print tray (I really need to clean it better before trying to print!) – but it was a pretty painless 3D print, and boy, do I love this yellow translucent filament!

With the print came a couple of surprises, as is so often true. One surprise was great, one less than great – more on both of these in a moment.

So clearly, I need to make some tweaks to the design…

3D Printing Mystery Continues…

Troubleshooting - Kevin CaronWouldn’t it be awesome if things just worked?

Yeah, they do sometimes, but especially in these early days of 3D printing, there are so many variables and things change so quickly that it seems there are myriad things that can and do go wrong.

Lately I’ve been battling a problem with both of my deltabot 3D printers, and I still haven’t figured out what is causing it.

The result is ugly: they just stop printing. For no apparent reason. Everything is going well, and then the hotend just stops moving.

Aaaargh!

I can’t just give up – it isn’t in my nature.

So I’ve been doing what I always do when troubleshooting any problem ….

I work through a process of elimination, testing and ruling out various possibilities.

Here’s what I’ve done thus far:

  1. Confirmed that it isn’t on just one 3D printer. It seems that I’m having the same problem with both deltabots.
  2. Confirmed that it isn’t Windows 10. That’s because it’s also happening on a computer that is running Windows 7. If it were just Windows 10, that’d be one thing, but the other computer hasn’t had an update in years and ran just fine.
  3. Confirmed that it isn’t the host program. I’m having the problem with both Repetier – two different versions of it – and Simplify. I’ve checked Simplify’s log and see it says the firmware is unresponsive, which brought me to my latest hunch (below).
  4. Removed the host program from the equation altogether. I put the file directly into the Gigante (yes, I used a ladder to do it). Same problem.
  5. Confirmed that it isn’t a power problem. One of the computers is plugged directly into the wall, while the other runs through an uninterrupted power supply.
  6. Ruled out the file itself. This has happened with several files, so it isn’t the design.
  7. Made sure it isn’t a filament bulge problem. It’s happened with various filaments, including two different diameters (3 millimeter and 1.75).
  8. Noted that it has happened shortly after the print started and just before it finished. If it were related to the file length, you’d think that would be more consistent.

At this point, I’m thinking it might be the controller board. I believe both 3D printers have Smoothie boards, so that might be it.

So I’ll just keep poking around on forums, talking to people, consulting my expert, and eliminating problems, hoping that one of them is the solution that gets me back up and 3D printing again.

And if this is just a test of my patience, I hope I have already passed!
