  1. This is interesting to me. Are we talking about transferring COLOR to clay or being able to cut or form a shape into the clay? If adding color imprints, at what step might this best be done? The answers could guide our upcoming advanced 3D immersion class exploration. We like to give the students real-world lab exploration projects. And, this sounds interesting. Smooth-on has a variety of materials for creating molds and/or stamps, I've not nee happy with creating stamps for printing on paper; but, our cadets might be fascinated with finding the best material for stamping color on ceramics surfaces. Cool!
  2. Thanks. I fully agree. One you done or two, the process becomes quite simple to manage. I like the ability to zoom in and out on specific features.
  3. Ceramic work is a three dimensional art form. And, I love viewing this art form in 3D viewers. The primary 3D viewing platform these days is Skeptchfab. It's capable of showing a 3D design or captured object from all sides and at any angle. The good news is that it is free. And, you decide whether or not the general public can see it without a direct link you provide. Moreover, you can block downloads. Capturing real-world 3D objects is getting easier and better all the time. While we have 5 different dedicated 3D scanners, at YouthQuest Foundation, we've come to rely on photogrammetry more than scanning to capture objects and turn them into virtual objects that can be uploaded and viewed in Sketchfab. Photogrammetry relies on video or a series of images to construct a 3D file. Our favorite is 3DZephyr. While there is a free version that works quite well, we use the next level which allows for more images and smoother captures. Samples of 3DZephyr captures can be found HERE. Qlone is an app available for the iPhone and iPad that was used by the students of iTech Vancouver Middle School to create a virtual museum containing over 100 historic objects from Fort Vancouver. iTech Virtual Museum Color and shadows are important to the capture process as changes in these dimensions provide the reference points for stitching together the individual images to build the 3d model. The Sketchfab Viewer can be embedded in your personal web pages. I'd be happy to help anyone that might like to explore these tools. I can tell you this. There is a small learning curve; but, a HUGE feeling of satisfaction seeing your work in 3D.
  4. I agree. Knowing a location, or even a general area, invites nearby people who could possibly help directly speak up.
  5. In this case, they glazed and fired the piece. So, it arrived completely finished. The bulk of the cost was shipping from the Ukraine. Their headquarters is in New York; but, their print-on-demand is only gased in the Ukraine for now. I suspect that they might set up a econd print-on-demand site in Hartford, CT at some point. That is where I expect to go see the Ceramo Zero Max. At YouthQuest Foundation, we suspect that ceramics 3D printing will be an important component of our training for at-risk young people. As such, it's important to us to explore the viability and possibilities. We are educators first and foremost, so communicating what we are learning along the way is part of our DNA. In this spirit, I have started a new blog to document our progress and communicate our findings. There isn't much there right now; but, it should grow a;most daily. http://3Dfired.blogspot.com The reason we are a good fit for this kind of exploration is that we have been teaching 3D design and printing for years. So, we know that side of the equation. We already have experience with both SLA and powder/binder printing technologies and, I have a personal electric controllable Kiln that we can use while experimenting. If I get in over my head with the clay post-processing side I have my daughter to bail me out. So, I am hopeful that the blog will be helpful to people coming from both the design and the clay side as they consider 3D printing of ceramics. For right now, we are limited to being able to explore the SLA technique of printing ceramics. Frankly, it is not my favorite method of 3D printing. While it produces beautifully detained prints, the resins require extreme caution. And, there are many more failures than one might how with a powder/binder printer. But, it is what is available right now and this is so important to us that we will work with what we have until something better comes along. Which means we're really hoping the Kwambio Ceramo Zero Max turns out to be reliable and effective.
  6. Thanks! Let's see if this link to the 3D viewer on Sketchfab works. It is not a captured 3d image, it's the original design colored using Meshlab. But, it should give everyone a good idea of the design and how well Kwambio pulled off the print. https://skfb.ly/6KAC6 BTW, Sketchfab is a terrific platform to show ceramic works. I use 3DZephyr to capture real world objects that can be displayed on sketchFab. Here is one such capture. https://sketchfab.com/3d-models/apulian-vase-300-400bc-5f8ea5f99a24432b85593b7a98216abe
  7. At YouthQuest we are interested in a wide variety of 3D printing technologies to see how they might be helpful for the at-risk young people we serve. While most of our instruction is done off-site, with consumer 3D printers, we do have a space we call the 3D ThinkLink Lab where we bring those who have shown the most effort for a week of advanced 3D scanning, design and printing using professional additive manufacturing printers. It's operated as a true lab in that the cadets test new equipment and techniques and prepare a report at the end. Recently, Formlabs released version 5 of their ceramic resin for the Form2. And, Kwambio announced a desktop 3D printer at about $5,000. It's essentially the same technology used in their professional printer that they use for their ceramics print-on-demand service. We have a full-color powder-based 3D printer. But, it uses gypsum as the powder and essentially Crazy-Glue as the binder. The down side is that the output cannot be fired, so it lacks durability. Thus, the idea of a printer that outputs ceramic greenware that can be fired is VERY appealing to us. So, I decided to take two paths to explore 3D printing of ceramics. (1) We obtained a donated Form2 and purchased Ceramic resin to test and (2) I ordered a printed part from Kwambio as the basis for initial comparison between the two technologies. The Kwambio ceramic print is of our own design and based on Kwambio's guidelines. We purposely added internal features and cut-outs that might be difficult to accomplish by hand. While a very skilled artisan using a coil technique might be able to pull it off, it certainly could not be cast. And, would really take some effort on a wheel. The printed object arrived last night. An image is attached. The printed object is 58mm high by 72mm wide, which is within one millimeter of the design specs. While my photograph may not do it justice, the surface quality and color character are stunning in person. If I actually had one of their printers, I would make the object at least twice as large and finish it quite differently. But, at least I now know the baseline of what a clay based powder 3D printer can do. I will be printing roughly the same design on the Form2. The reason I say "roughly" is that the guidelines for the Kwambio suggested 4+mm walls and the quidelines for the FormLabs Ceramic resin call for walls of 2-3mm. There are reasons for these difference which I will be discussing later. But, for now, we'll have to wait for the first ceramic print out of the Formlabs. At some point, I hope to capture the object in 3D for viewing at all angles on Sketchfab.
  8. Perhaps that is why 3D printing has been called a "disruptive technology." Perhaps there is no place for 3D prints in juried shows at all. That would seem reasonable as long as those submitting works are honest. But, does a work have to qualify for a juried show to have income value for an artist or designer? Isn't there a place for production work that permits an artist to continue making jury level objects by providing income at a production level? By the way, Dizingof is quite ready to sue those who rip off his designs and use them without permission. He did that with 3D Systems and some other big 3D printing companies that showed prints of his work at conventions. On the other hand, he does sell commercial licenses to print his work with attribution. I think the word "manufacturing" is a critical and valuable observation.
  9. Only at the risk of death should I crack the piece! I am DEFINITELY a coward!! Personalization is probably the greatest appeal for 3D printed ceramics for consumers. Not everything has to be art to have personal value. The questions regarding art shows is an interesting one. Those creating handmade jewelry have to contend with borderline products in the next booth all the time and I know that is very painful to those passionate about their work. Let me throw one more thing into the mix. Ceramics is unlike just about every other medium in its permanency. It is not uncommon for the most common ceramic items to survive for thousands of years. That alone adds some value. I was watching a program about a mass grave found that held the bones of more than a thousand people. There were cloth fragments, strands of gold and some jewelry. But, absolutely nothing was found that could be used to identify a single person. The value at the time it was created might have been insignificant; but, a single small piece of personalized ceramics on just one of the people would be a major find of tremendous value now.
  10. Both comments are interesting observations. Thinking about it, printing a Dizingof design WOULD be more like manufacturing. That is a VERY astute observation! The instagram link represented the works of many artists using Kwambio's print-on-demand service. But, you are right. It IS possible to scan just about any object and reprint it. While it's not a huge problem today in the ceramics world, I suppose it is something we have to well aware of in the future. But, there are ways to thwart a 3D scanner or photogrammetry software. For instance, some of my daughter's ceramic work is next to impossible to duplicate from a 3D capture due to the open areas.
  11. I think you are right on both fronts. Since I do not consider myself an artist, I think I fall into the category you describe. In fact, when I find threads regarding the Formlabs ceramic material the most asked question is, "What's a good kiln?" They have little or no experience in clay at all. Traditional clay artists will need help with 3D design and 3D design artists will need help with the basics of working in clay. I would hope I can be of help to both groups of people and a catalyst for expanding the creative process for everyone.
  12. This is EXACTLY why I started this thread. I wanted to hear questions like this one. Here are links that those wishing to explore this topic might find interesting. The first is to the web site for the 3D artist known as Dizingof. https://www.3dizingof.com/product-category/math-art/ The second is to the gallery of objects that Kwambio has printed from various artists and designers which gives us some idea of how some artists are already taking advantage of 3D. https://www.instagram.com/kwambio/ Now, all of these items are glazed in a single color as the printers are not yet released. The pipes are VERY cool. But, do not really require a 3D printer to create.
  13. Every 3D printing that is capable of producing in ceramics ends up with greenware as the output at one stage or another. It's what happens next that determines the uniqueness and/or value of the end result. Perhaps those embracing 3D printing will focus on the unique design capabilities of 3D design, making shapes impossible to cast or natural random drooping of unsupported elements. " A wise 3D-printer of ceramic ware will introduce random variations in her design code; every mug made on the printer will be unique! " This is certainly an option. And, very easy to accomplish. "People like handling handmade items -This will never go away. We will all never agree on this as its a Ford/ Chevy topic " I don't even think we HAVE to agree or embrace it. That's the beauty of creativity and craft. It is the INDIVIDUAL expression that matters. In some ways, if one looks at 3D in totality, it simply widens the creative opportunities like incorporating 3D scans of people and cherished objects into the design. But, it will never replace the quality that hands bring to a piece. It will simply have a different charm.
  14. " Your hands are a 3d printer man, one of the fastest on the market " That's for sure. I LOVE using 3D printers; but, raw speed is NOT one of the strengths.
  15. Two thousand and three hundred years ago, a potter and/or a painter of pottery might have had the same thought. But, that person's work sat in the ground for two millenia and two centuries until it was found to be appreciated once again. It's sitting right in front of me and I appreciate the work of that unknown "bottom feeder" with deep admiration every time I look at it. Could I appreciate a painting that had been in the ground that many years? Now, you can enjoy it virtually! https://sketchfab.com/3d-models/apulian-vase-300-400bc-5f8ea5f99a24432b85593b7a98216abe Remember, as you view it. The painting is in REVERSE. The UNPAINTED region is in red and the PAINTED area are in black. While this is not the finest example of this type of work, think of the skill that took!
