3D Clay Printer: First Weeks

This was our first "print." While the machine was priming it began to extrude and wouldn't stop when we "stopped" the "print" so I just caught the clay on a piece of paper on my hand, twisting as it came out.

Yakima Valley College Gets A 3D Printer for Clay

At last year's NCECA Conference in Portland, I saw a 3D Clay printer being demonstrated. I also saw a good deal of 3D printed clay at the conference, though I only saw one person (Brett Freund) who was using the printer in a really interesting way. But I thought the newness of the process and the fact that this machine prints wet clay, rather than liquid slip, which means that we could print, then alter the prints immediately, meant that there were possibilities for my students to be creative and really explore the unknown possibilities of this process.

Our first successful print came during a day when we worked at it for more than 5 hours, but only managed two successful prints total--and then broke the microSD card inside the machine.

After the conference, I submitted a proposal for my school to purchase a printer for our classroom. The proposal was approved quickly and we received the printer early in the fall. Of course I didn't anticipate that it would be that easy to get started. We got the printer, but the pug mill attachment was incorrect and we spent 5 weeks looking for a solution. Eventually the YVC facilities folks hooked us up and we were able to print for the first time at the end of October.

First Attempts to use the 3D Clay Printer

The first print that wouldn't stick. I can tell the machine starts too fast, but I didn't know that then, in part because the instructions and videos don't actually say how fast to print.

I took some videos of the printing process in October, but was feeling really frustrated because the clay often didn't stick to the printing surface and the extruded layers sometimes didn't stick to one another. I didn't understand why and had trouble finding out why from someone with experience. 

Our first successful print, stuck to the base, even though almost all the other prints needed a clay base prepare ahead of time in order to stick to the base. The company contact condescendingly told me that we should have had a piece of red constructions paper, and later, re-watching the videos I see where the paper was mentioned, but I still submit that a paper checklist with this sort of information would be much more helpful than videos I can't watch easily in my studio.

Since that first day, I've used the printer 4 or 5 days to print a variety of digital objects that came with the printer software, as well as some student designs. Of course it would be really helpful if I were just working with the printer during this time, but I was teaching class, grading assignments, helping students, attending meetings, and completing other full-time faculty obligations, so my time with the printer has been relatively limited. 

Troubleshooting & Trial and Error

The 3D Clay printer comes with no written troubleshooting instructions and minimal written instructions of any kind, including set up. The customer is advised to view online videos, which I did before setting up and attempting to print, but all the videos assume that you are more familiar with the process and 3D printers in general than I was when we began. I needed a list of definitions before I could even understand the videos.

Our second successful print on the first day shifted and leaned because the printing speed was faster than I would recommend. I can't say it is faster than recommended, because I cannot find any speed recommendations.

In our initial prints, we followed all the directions we could remember from the videos, but without much guidance as far as speed of the extruder, speed of the movement, or much of anything else, we mostly were just trying stuff at random. At the time, I wasn't sure that I would be able to figure out the issues without help from someone with experience with this machine. Now, however, looking back at the first video, it is pretty easy to see what went wrong at the time--it was printing too fast at the start. We've also learned that putting down a layer of wet clay for a base is usually essential.

This print was done on the second day, when the speed controls didn't appear to relate to the actual experienced speed of the print.

The thing I am not able to figure out is why the printer/software/file combination sometimes prints at a different speed using the same settings. You can hear me explaining the situation on the video to a student. This print is moving much more slowly than the previous print, but I'm printing the same file, the clay is coming from the same tube, minutes later, and the extruder speed and x/y movement speed are set at the same speeds as in the print immediately before this. The only difference is the actual experienced speed of the x/y movement is much slower.

A successful print on the second day, when the speed varied at random.

The machine seems to be working basically fine and is generally fairly reliable, but the support is difficult to navigate and frustrating when much time and effort is wasted--especially when I can't get much more than a couple hours at a time to work on it. I get the impression that the company is overwhelmed with the machines they are sending out, but they could provide much clearer instructions, troubleshooting, advice, and support--at least from this new customer's perspective. 

The second shape we printed requires some work after printing to open the closed top and open the negative space of the handle.

Students Figure the Thing Out

At NCECA last year, I had asked how hard it was to learn the online object making software. The woman at the booth suggested that the students would just figure it out. After making a few attempts to learn various 3D object making programs, and discovering that they and the tutorials are often designed to now work with a Mac (they keep directing me to right click on my one-button mouse), I was hoping the students would come through for me.

This student's design worked fairly well except for the open section on top of the leg. 

I opened up use of the printer to my students, letting them know that I am not much of a resource for the object making software. I told the students they could look into online tutorials for programs like TinkerCAD, but that I wouldn't be able to help. One student came back with a design she had made herself and it printed correctly on the first try and, to my surprise, the second. Then she and another student proceeded to print successfully or semi-successfully over the course of 2 days and 4 prints. There were some unsuccessful prints mixed in too, but fewer than at the start of our printing process.

This student design was also the first object to successfully print twice in a row. 

Hopefully soon I will be able to print some finished images of work and maybe even get some time to spend on the printer and software myself.

Come See My Work

The next two weeks are fairly busy with art exhibitions and openings, several of which feature my work.
my work at Boxx Gallery

First, this Thursday, November 2, the Maker Space Gallery is hosting paintings by Amanda Ontiveros. Opening reception at 6-9pm. Yakima Maker Space is on 1st Street between Yakima and Chestnut Avenues.

Amanda's work at Maker Space

You can see my work twice this Saturday, first at Boxx Gallery in Tieton with a reception from 11-1pm and at Larson Gallery in Yakima with a reception from 3-5pm (awards at 4pm).

my work at Larson Gallery

The Boxx Gallery show is called "What's on Your Plate?" and features works related to plates, eating, kitchens, and associated imagery and forms. I've got a completely non-functional plate sculpture and a wacky mug in the show. I haven't seen much of what other folks have.

The show at Larson Gallery is the annual Central Washington Artists' Exhibition, featuring a small sculpture of mine. Also showing at CWAE is Meghan Flynn, drawing and design instructor at Yakima Valley College. Her hyperrealistic drawing of rocks is worth checking out.

All three receptions are free and open to the public, so stop by and join us. Boxx Gallery is open on Saturdays from 11-1 and the exhibition is open through the end of the month. Larson Gallery is open Tuesday-Friday 10-5 and Saturday 1-5, except for Veteran's Day and the Thanksgiving Holiday. The exhibition closes December 2.

one of my mugs (soon to be) at Oak Hollow Gallery

Also opening next week is the Holiday show at Oak Hollow Gallery. I will have some mugs and bulbs for sale. The show opens November 7, but there will be an open house November 11. The show runs through the end of the year, but work is only there until it sells.

Decal Mugs

this mug is fairly big and bright, didn't photograph as well

Last week I applied and fired some decals on some functional mugs. Some of the mugs had decals over-fired previously, but some of the decals were applied to fresh mugs.

I made the mugs near the end of the summer quarter when I was testing out my new ball openers.

the Temmoku glaze works well on this slipped surface (no cat)

I was using some cone 6 glazes I had used last summer, as well as some new (to me) Potter's Choice glazes. I applied decals on most of the mugs, but skipped one with a lot of texture because I'm happy with the glaze on its own.

I played around with some wiggly bases

The mugs don't match each other, mostly because I was trying out a variety of different shaping and decorating techniques and was just entertaining myself.

I just like this bottom swirl, even if the photo is odd

I was especially happy with a few spiral trimmed bottoms which I highlighted with underglaze colors.

the cats worked better on the curved surfaces than other decals

The decals I used the second time worked very well, for the most part. The cats show up well in both gold and black on all of the glaze colors. 

this cat seems to be floating in space

I particularly like when the cats seem to be interacting with the landscape of the mug.

I like the way the cats use the line of the mug to stand on

Some of the mugs are less successful, in part because the glaze colors look a little odd in the second firing.

the cat shows up ok, but the color has become a bit metallic

I used mostly cat decals, but I had a few other science-y decals. These worked out less well, in part because they were applied on top of darker glazes and in once instance because they were incompletely applied.

the decal didn't completely adhere to the curved surface, and therefore fired off and out of round
It's tough to get the decals to stick well on curved surfaces, so after trying for a while, I decided to just try it out and see what would happen.

the mottled glaze color obscures some of the decal color

A few of the cat decals showed up with a line around the exterior of the cat. The line is where the clear part of the decal was cut. 

the edge of the decal shows up on this glaze

I cut them haphazardly because I thought the edges would be invisible--and they were on most mugs. On the darker, more metallic glazes, those edges showed up as sloppy outlines around the cats.

boo, hiss
The frustrating thing is that the fix would have been so easy, I could have simply cut the cats out closer to their edges, but I didn't and now it is too late. Maybe these are a good cups for someone with poor eyesight or a dark kitchen.

I plan to take a few of the mugs to Oak Hollow Gallery for the holiday show. The show opens in November and runs through December. I will bring some mugs and some bulbs, which will be sold individually. Let me know if you have requests, I deliver the mugs and bulbs at the end of this week.

Besides the mugs I made for the holiday show (well, I made them for fun, but some are going to the gallery), I also made a few smaller mugs with some clay that was recycled by my young helpers this summer. I used decals on these mugs, too, and the helpers each got their own mug as thanks for recycling clay with me.

I like how the cats seem to be playing in the grass on these mugs.

Decals and Firing

over-fired cat decal looks faded and dull

In March, when I was at the NCECA conference, I noticed lots of people working with decals, especially gold decals. I bought a few and tried some out this summer and fall. 

gold and black cat decal sheets with some of the cats cut out and used already

I wanted to try them and see if they'd be useful for students or for my own work. Unfortunately, when I bought them they didn't have anything attached to them that indicated the name of the company. I might have had a business card or receipt, but by the time I was ready to use them, I'd lost that. 

faded dull kitty

This sounds ridiculous now, but I looked up how to apply them, but somehow misremembered or misread the firing instructions from the seller or from the internet. I assumed they could be fired to a low bisque temperature, so that's what I did.

some of the over-fired gold cats cracked and shrunk (perhaps because the glaze melted a bit)

Perhaps surprisingly, some of them worked out ok. The colored decals seemed basically fine and some of the gold decals were ok, but others faded out to varying levels on different glazes or cracked and shrank on the surface.

Realizing I was doing something wrong, but still pleased enough with the good results to try again, I finally looked up the firing directions online. The company is Milestone Decals, by the way, and the application and firing directions are not hard to find on their website. The error here was all in the user and not the product.

Anyway, it turns out I had fired the decals much hotter than I should have done. Last week I received a small order of mostly cat decals to replace the ones I fired poorly. I layered some of the cats over the existing cats, though a few original cats look just fine. I bought both black and gold cats to replace the gold cats I had before. 

gold cat decal, over-fired but looking basically ok

I've got a few cone 6 mugs I made this summer and will try to get the decals on and fired (to cone 017, it looks like, not cone 08) this week. If they work out well, I plan to take some of them to Oak Hollow for the holiday show starting in November.

What's On Your Plate and Mug

"What's On My Plate" 2017

This summer I made and finished several pieces within a few months (as opposed to the work I started last year and finished this year). One of these is a "plate" sculpture for an upcoming invitational exhibition at Boxx Gallery in Tieton. 

Plate in Progress

The show, which opens November 4, is called "What's on Your Plate," and is a fairly broad collection of works in a variety of media all referencing eating and cooking, kitchens, dishes, and, well, plates. I took a fairly literal approach and put my sculpture on my plate.

this piece was originally intended to be attached to the plate and will now be in CWAE 2017

This piece just came together this weekend and I'm pretty pleased with the three tails of bicycle chain that are coming out the one end. The concept is similar to a piece I made a few years ago.

"Cerberus" 2014

I also made some chain mugs this summer, mostly just for my Dad, but I think I will show one of them with the plate piece. They may not be super functional (don't microwave them), but they're fun.

Chained Plate and Mug

At the last minute (sometime in September), I decided to throw a few mugs to test a new tool. It occurred to me to add an attachment for a chain handle. I'm happy with the concept, but my execution was a little sloppy. I should have left room for a pin to connect the chain to the mug, but I only left room for epoxy.

"What's On Your Plate" opens Saturday, November 4, 2017 with a reception from 11-4 at Boxx Gallery on Wisconsin in Tieton, WA. A portion of the proceeds from all sales goes to Highland Food Bank. The rest goes to the artist. Boxx is open Saturdays from 11-4. The exhibition runs through November 25, so you've got just 4 Saturdays to see the show.

Central Washington Artists' Exhibition

Last week I found out that one of my sculptures was accepted to the 62nd annual Central Washington Artists' Exhibition at Larson Gallery this year.

my piece "untitled" for CWAE 2017

I was surprised by which piece that was selected for the exhibition this year. I entered three pieces, but I really had my mind set on one of them, the first large piece that I've finished in two years. I finished this piece just before the entries were due for CWAE this year. I like the piece, it worked out how I planned. I'm happy with the spinning blue parts on the bottom, and I'm fairly happy with the pictures of the piece. 

my sadly rejected new work

In completing the application, I decided to toss in a couple of small pieces just because they were ready. Besides the big piece, I had finished maybe 3 or 4 small sculptures and I have a few in various states of epoxying on the floor in my studio. I didn't think the small pieces were likely to get in, but one of them did. It is a pretty small sculpture, one that required no brain power whatsoever from me in the making, because I've made this kind of sculpture numerous times before.

"Petal/Pedal" was in CWAE 2016

I'm not sure what to think about which sculpture got in and which didn't. The juror could have been influenced by color, shape, size, title, or any number of factors. Maybe she doesn't like complex forms, but she does like complex color and texture. Maybe she likes yellow better than green.

this pod was in CWAE 2016

Certain types of galleries and art fairs that I've shown in over the years have preferred smaller, more affordable sculpture, especially sculpture that does something (like a fountain or a lidded box), but that seems unlikely to influence a juror's decision. On the other hand, last year I had four entries accepted and they were all small. Each year there is a different juror, so this year's juror presumably didn't have the same criteria as last year's.

this lidded set was in CWAE 2016

The possibility remains that I have overlooked a significant flaw in my newest large sculpture or a significant quality in the new small one. As the maker of the work, sometimes it is hard to see the works objectively. As I review the image in this blog post, my favorites are the top two, both finished this year.

my other (silly) new sculpture

I've avoided mentioning the other new sculpture that I entered in this show. This one's a bit silly, really. I've been working on this one for over a year as well, but the attachment angle and finished surface changed from the original plan. I had intended to attach a bicycle break handle, as I ended up doing, but I intended to attach it facing the other way. I intended to attach another piece on the end of the metal handle, but that didn't get done. I ended up changing the handle orientation because I liked how the handle echoed the angle and line of the body of the sculpture. But everything about this sculpture is a bit silly. The surface is unusual for me, the handle is just plain odd. Sometimes I want to try something, as I did here, but I'm not sure if I want to defend what I tried once it's done.

both of these sculptures were in CWAE 2014

If you'd like to see my new little sculpture, this year's Central Washington Artists' Exhibition opens at Larson Gallery on November 4 with a reception from 3-5pm. The exhibition continues through December 2, 2017. Larson Gallery is open Tuesday - Friday 10am - 5pm and Saturdays 1pm - 5pm.
