Clear Bottle Prototype

[@cmarcrum25]

I find that slinging the excess material onto a scrap piece of cardboard help with runs and bubbles. If you miss anything you can use a brush to pops bubbles before that cure

[@stuartkorte1642]

Clever sanding ball.

[@philippeminerve7143]

Didn't find you polishing compound in the description. Thank you for you so inspiring videos.

[@EricStrebel]

Apologies...I have added it.

[@stanleythrewbrick]

I appreciated (very much) actually _seeing_ the cleanup process (which, maybe that _was_ your intention here?) - but, what would have been the downside, if any, to (as you mentioned,) having “the printer cutting the bottom part off, so _they_ can sand/finish the part” for a prototype of this nature? Thanks!

[@msk3153]

Really cool, thin transparent pieces like this are an absolute nightmare to get right

[@freakinccdevilleiv380]

Fantastic!!

[@GeorgeGraves]

Drill presses don't like those side loads much - keep an eye on the run out.

[@KeishaDeniece]

Thankyou for this very good helpful video!! Can you maybe also make a video about 3D printing a bottle with screw lid?🙏🏾 I want to make a model of a ball shaped bottle that can hold glitter water and can be refilled. I use Blender for the model but I hear about the nuts and bolts assets not being accurate enough. And then I want to make a silicone mold from it to use for epoxy resin. So it can become a product.

[@DrFiero]

You can get felt and cotton polishing bobs in wheels, cones, balls. Have a mandrel on them just like your green ball. I use them for polishing things like intake manifolds down in the nooks and crannies. They'd work perfectly for the lip of the bottle inside!

[@pułkownikkaczodziobyzpodlasia]

what a handsome finish!

[@freakinccdevilleiv380]

Video suggestion: How about making clear plastic domes out of thin 0.5 mm acetate or PVC sheet. These could be useful for many things and might be simpler than those of heavy gauge acrylic.

[@jellygrass777]

I absolutely love your videos, always learning from your ideas!

[@JGDeRuvo]

Nice!

[@dejanvracarevic208]

Hi Eric, when taking photos of glass containers insert a sheet of paper (black or white) into the bottle, depending on the background! ;-)

[@Tarbard]

It's very satisfying seeing the clearcoat turn the inside transparent. How strong is the bottle btw?

[@EricStrebel]

Prefect for prototyping, not suitable for everyday use.

[@adamblake2518]

Awesome video! So helpful. I'm wondering if you recommend doing multiple coats of clear coat, and how long you let it dry before sanding?

[@garagemonkeysan]

Great video. Cool technique. Mahalo for sharing 🙂🙏

[@dinojjoseph7791]

Great video

[@EricStrebel]

Thanks

[@iainmcculloch5807]

Looks like a pretty labour-intensive process, but the final result is absolutely worth it!

[@DIYGarage_SoCal]

Well done! Thanks for the process! I used a spray paint clear Rustoleum with similar results. I'd love to try it with the two part urethane clear. Hopefully it's more durable and won't yellow over time :)

[@DEtchells]

Wow, an amazing result! (I’m not sure whether I’m more impressed by your technique or your patience 😁) Checking the link for the urethane reminded me: Resins tend to be pretty expensive (vs my personal budget anyway), and usually come in much larger quantities than I need for the small projects I typically do. Is there anything to be done about extending shelf life? I’ve found that refrigerating small amounts in 100% full containers helps, sometimes using the argon/nitrogen mix from my MiG welder to flow over and flush the container as I close the lid. This can extend life a fair bit (to maybe a year?), but I’d like to be able to go longer. Can unmixed resin or unopened epoxy be kept below freezing to extend life? Any other thoughts or suggestions? Thanks for your videos, they’re incredibly informative and practical!

[@Rouverius]

Very cool. I was playing around with clear PLA. If I tweaked it just right I could get it semi-transparent like textured glass but not as clear as this bottle. Have you tried this technique with an FDM filament before?

[@EricStrebel]

Does not work, did a video on it actually

[@roryleitner1532]

What materials can be dissolved in acetone or xylene then be used as a material for injection molding? I have some beautiful colored acrylic, but when I heat it to try and form it to the shape I need, it shrinks! At lower heat hazing appears at bending areas. Please help.

[@EricStrebel]

Don't really know, I have never used that process

[@slimewizard6141]

How do you get into what you do? This seems like a job that I would love to do. Any tips?

[@Haskellerz]

What does it look like if you ask pcbway to sand both sides for you?

[@EricStrebel]

They want to cut the bottom of yo do it.

[@smartassist9700]

Is your method of making/reproducing items cheaper than 3-D printing? Basic tools cost estimate? Liquids, pressure tank, key core items. Can you give me idea? I. Anew by and deciding best route as I have limited income.most items I make would be 1foot square or smaller. 6 to10 inches. Tech containers/waterproof.

[@EricStrebel]

That was a 3d printed part.....

[@scottgray6276]

Would it work to leave half of the sanding ball disks off, resulting in a flat-ish bottom sanding dome, to deal with that right angle, where the side meets the flat bottom?

[@EricStrebel]

Not completely flat on the bottom

[@royalrevue23]

The bottle 3d printed ?

[@EricStrebel]

Correct

[@ooslum]

Good grief Eric, I've never seen a sanding ball before, cheers.

[@Antipico]

Great! Will the base print stay clear over time or do you have to worry about UV over time?

[@EricStrebel]

The clear will be fine, not sure about the uv stability of the part though

[@prokremelskidezolati1426]

large resin 3D printer and clear resin...that is it
