I needed this today

Can't stop seeing stars

I'm in this with you.

When you follow your heart, love is the answer

  1. how did you come up with the styling? I can design things that mechanically work, but how do I take it to the next level and do pretty too?

  2. Practice. I’ve been engineering and modeling for more than 10 years at this point. It’s all part of the design process. Pay attention to things that you like the style of and figure out what details make it that style.

  3. I, like a few others, would like to know if there is an online source for the three switches (especially the e-stop button) and how you wired them up. Excellent job on the 3D switch panel btw, it is so satisfying to have an idea and be able to create an actual physical object that is useful. We live in truly amazing times.

  4. I got them on Amazon a long time ago. The e-stop is decent, but the other two are pretty low quality. They work fine, but I’d like something a little nicer.

  5. I like that, very neat, nicely designed

  6. I like the design and implementation a lot, but the Aluminum plate was just fine.

  7. What about that air pocket, won’t that make it explode in the bisque firing?

  8. They don’t explode if they are completely dry. Moisture is what causes explosions.

  9. I think I’d like this design more for keeping the mug cool to the touch than keeping the contents hot. Will the end product have a handle?

  10. That’s basically the idea. You’ll be able to boil in the microwave and still be able to pick it up. It won’t keep your drink warm for hours, but it’ll keep it a much more consistent temperature than a regular ceramic mug. I’m excited to test it once I get one fired. And the plan is to not have a handle at this point.

  11. What happens when it gets baked. Wouldn't the air in the isolation area expand and deform the whole mug??

  12. Air pockets can be fires as long as the piece is completely dry before firing. The dry clay is strong enough to hold the air pressure, but it will explode if there is any moisture inside.

  13. Awesome design but I’m curious if there are any issues drying/firing these without cracks or them blowing up in the kiln? I was always taught that air bubbles are the enemy?

  14. Thanks! It’s not an issue if it’s done correctly. It has to be completely dry before firing.

  15. This is unbelievable. Can I ask what your background is, engineering maybe?

  16. Thanks. I’m a mechanical engineer and have been making stuff since I was a kid.

  17. Wow this is impressive! I love the wood integrations. Can I ask what your design process looks like? Do you kinda just hand make prototypes, measure, and iterate or do you plan a lot of it out in software? Is the wood cut out w/ CNC and hand chiseled? I would 100% subscribe to your YouTube channel if you had one - this is awesome

  18. Thanks! At this point I design pretty much everything in CAD first. I used fusion for this. Then physically build it and iterate from there. Wooden parts are all designed to fit together without hand finishing. I’ll probably put a video together about this once I have a finished mug.

  19. The parts are PLA printed on my Ender 5 plus. It screws together using threaded heat set inserts. Wooden pieces were cut on my PrintNC cnc router.

  20. Do you do a test slip everyday? We did this when working at a slip casting company. Measure wall thickness at something like 90 seconds, 3 minutes and 5 minutes (or something like that based on the properties of the slip). Plot it and determine your time based on the wall thickness you want.

  21. Yeah, I’m planning testing the slip pretty frequently. I probably won’t be mixing up new slip that often, it’ll be interesting to see how much of a variation there is between batches.

  22. How did you make the machine? Would love to learn more if you have a YouTube channel or something.

  23. I made it with my cnc router and 3D printer. I will probably make a YouTube video at some point once I get farther along. I post more frequently on Instagram.

  24. Have you tried actually firing them? I was under the impression that things with air pockets crack or explode in the kiln.

  25. Yeah. I’ve made similar mugs in the past, but I was making them a little differently. Air wont cause explosions, but moisture will. They just need to be dried completely before firing.

  26. Not to sound too obtuse, but what is the benefit of a double-walled ceramic mug versus a steel one?

  27. I just don’t really enjoy drinking hot stuff out of the steel mugs and it’ll be microwaveable.

  28. Do you happen to have something that's not facebook where we could follow?

  29. Is there a hole somewhere to help with glasses escaping during firing? (For the area between the double walls) and do you think it'd hold a vacuum if pumped down before use?

  30. There won’t be a hole. If it dries completely before firing it won’t explode in the kiln. I have a few ideas to create a vacuum, but I think it will provide enough insulation even if there isn’t one.

  31. That is awesome! Could we see what one of the mugs looks like too?

  32. Thanks! I don’t have any finished mugs from this machine, but they will be similar to these that I made a while ago

  33. It must be difficult to maintain an even wall thickness unless you have a catalyst sprayed on the sides of the mold or are using a wicking plaster like he described?

  34. Wow, that is cool. How Is it possible for a shape like that to survive firing?

  35. If the piece is completely dry and there is no moisture in the cavity it won’t explode. Air doesn’t create that much pressure when it is heated. The water is what causes explosions.

  36. So I assume you put slip in it to slowly coat the walls into a mug? Pretty cool idea!

  37. The mold starts nearly full, as water absorbs into the plaster the slip level drops. I am tipping and rotating the mold so the walls stay evenly coated as the level drops.

  38. Why not show the results if it's working? Looks cool! I like the repurposed skateboard wheels.

  39. Where are the other two skateboard wheels?

  40. Still on the skateboard…. Waiting to be stolen if I ever need to make another one of these.

  41. The moisture from the liquid porcelain gets absorbed by the plaster mold, hardening it

  42. Congratulations that looks complex, so that's spinning and making a slush cast? How are you venting the air between the walls during firing (so it does not explode)?

  43. Yeah, that’s the idea, it will have liquid clay in it. If you let them dry long enough to get all the moisture out they won’t explode. I’m going to try a few things to attempt to create more of a vacuum, but either way, there is a noticeable temperature difference compared to a regular ceramic mug.

  44. Parts are PLA printed on my ender 5 plus. The body screws together using threaded inserts melted into the plastic. Wooden parts were cut on the PrintNC cnc router that I built… with 3D printed parts. The plan is to use these to slip cast a double walled ceramic mug. The machine uses an arduino to tilt and spin the mold because of reasons that are too complicated to explain without visuals. The mold is plaster with 3D printed retaining rings/forms.
