This is awesome!!! I was looking for a way to make lightweight slip-cast eggs for one of my projects, I thought it might be possible with resin but I wasn’t sure and this is IT!!! Thank you so much for posting this, I will be forever grateful! :)
Very cool! I've never seen this done outside of the ceramic's field. The stuff you come up with always blows me away! Great work bud! Keep kick that butt!
Rob's Hobbys thanks for the comment and support, feel free to share with your friends on social media.
Great Vid! Would love to see a video that expands on the particulars of the construction and use of the pressure pot.
Came here to say the same thing. Love to see how you made those handles and other modifications of your pressure pot!!
I love the direction your videos are taking Eric. Thanks for sharing yet again.
Very cool
Cool. Maybe you can cover the mold design and construction?
Jak Mang I would love to, have to see if that is possible sometime in the future. Super busy.
fantastic
🤯If only I knew about this occupation when I was in HS !!
Yeah most guidance counselors don't know anything about industrial design
Thanks mister.
Thx, sir!
Gotta try this myself
Nicely done Eric, quick side note, the ‘r’ in ‘Industrial Design’ is missing from your intro. Keep up the good work 👏🏼
jdrmirabelle yup, It got fixed shortly after this video. Thanks!
thank u
Can you please add contact information for the dry transfer graphic? I also need a graphic of good quality, like you have in this video. Something that will not rub off so easily.

Hey am so glad to come across your work its been hard but finnally i want to know if a hollow Epoxy resin tube can break easily or what is its durability guarantee is it like Lexan polycarbonate sheet ??
Depends on a lot of factors while thickness, size and how good your part is cast.
i LOVE THIS!
Wonderful stuff yet again! Can you share where you got your decals done?
Made 2 Hack the decals are from imagetransfers.com not cheap, but good quality.
Can you provide more explanation about the dry transfer. Thanks.
rotate85 A dry transfer/rub-on transfer is a semi-permanent application that can be applied quickly and effortlessly to a number of substrates. It is created by printing a special ink backed with adhesive on a transfer paper that can be rubbed off without the use of water or other solvent. Transferring the image onto any smooth surface, including wood, metal, glass or plastic.
can you provide a link as to where you send out the graphics file to have the special inked backed label made? Thx.

Thank you Eric for the info. Much appreciated. Keep up the great work!
Enjoyed the video, Eric.... also, how important is adding the heat to the pressure pot step? Is it necessary or is it solely used to help speed up the process? I have a pressure pot but it does not have a heating function.
JamokaJoe I like it because it help with keeps bubbles from forming as the urethane cures. Important when you are making clear parts. Glad you liked the video.
Great video 👍.
How can I slipcast a model using silicon liquid rubber. I want my model to have a particular inner as well as outer shape and be flexible for some expansion when air pressure is applied.
Great!
awesome vid! what do you call that dremel tip you used to trim the flashing?
I use an end mill bit
1 Query:
Have you ever done Urethane Casting with under-cuts? If yes... kindly please provide link.
I need a good Vacuum degassing unit and Pressure pot, what would you recommend.
Are you using the same amount of resin each time or are you using progressively less each time?
Quirky Dad yes, about 10 grams total in each layer, most of it get dumped out of course. The first later I used 20 grams, because I could not remember how much was need.
… also how can i mold a hollow Epoxy resin seamless piece in shape of a large rectangular capsule and where can i get the moulds from and the machine please help I’ll appreciate
I don't really know anything about your project but probably watch a few of my videos about how to make molds and cast resin parts so you can figure it out
So there's no need to block up your pour and drain holes during rotation because you keep it horizontal while rotating ?
correct 😀👍
@@EricStrebel Thank you sir, missed your reply there for a while!
Do you have a training course on how to make molds ? I would love to learn from you
Hello I am needing help with making a mold to make cylindrical candy . can you help
how can we make dry image transfer (decal) like that? 6:08
Hi Eric, can you help me?! I have to produce some parfums bottle prototipys the most similar as possible to the next industrial glass production. The master bottle doesn't exist, I have only 3D files...I think that use clear resin it will be the right solution because the 3D printing is not so clear. Inside it must be empty to be filled with the coloured liquid and it should have the right "glass" thickness on walls and base. I don't know how to start...and finish! Do you think that resin is the best way? How does the mold should be?
I saw some prototipys makes by others and were perfets, They seems make in plexiglass but without visible connections. I don't understand how they does that!
There is a video about it or can you show me how can I do?
Many thanks for your attention!
Your process would be identical to this one just a different form. The process is time consuming. I have made them in the past, they look very realistic and are functional
but in this case you have an object with the same walls thickness. You know that the parfume bottle has a high base and thick walls in different thikness. How can I make rhis effect using this metod? Inside there will be an empty area with a specific shape.
I would like to do a test, can you tell me if, in your opinion, is a good idea?
I will make two 3d printing resin mould, the first one for the external shape and the second one for the inside area made with a specific resin which melts with heat. I will use silicone spray on the walls of the mold. I'll make it a single casting. Does it will work?
@@gabrielegotti6578 yes, of course, the inside is tough to control, you can control the thickness of the base but not the inside shape of course. Post your results on social media @ botzendesign, I am curious to see your results. Good luck.
Can this method be used without the degassing and pressure equipment? Will it have the same result however be full of bubbles?
Yes depending on which resins you get for which kind of plastic you need to end up with you can use a painters tray and tap the whole tray down on a counter a few times to help agitate bubbles up to the surface, degass is just important if going for clear bubbleless parts.
is there another technique to eliminate bubbles when slip casting resin that doesn't require a pressure tank?
Bubbles depend on the resin type and the humidity in the air, the pressure pot basically eliminates those variables. Perhaps a different type of resin?
Which Crystal Clear from smooth on did you use?
👍
It’s also the same way they make hollow Easter bunnies
Barry Fields Bunnies are probably roto cast since they are closed at the bottom.
Eric Strebel the mass produced one yes, but I’m talking small batch hand made bunnies. After they dump the chocolate out they set the mold on a puddle of chocolate that how they close the bottom off
Or, you can have it 3d printed.
Seems very wasteful doing this, root casting sounds like a better proposition, but I could be very wrong
FYI you can skip the first whole minute of this video
Why? It sets up the video 😄
