In future episodes: Trying to figure out why our scanner isn't working.

Thanks for the video, some great info!

This video is so fantastic, I can't begin to tell you how informative it is for someone who's trying to bring a product to market and is going round in circles looking at sheet acrylics and spacers. Thank you for taking the time to make it.

I read a while ago that someone made bushes for his 3d printer from UHMWPE, wich is much cheaper than teflon, and he was extremely happy with the result.
Vesconite is a plastic developed in South Africa in 1958 and has very high weight bearing and low friction properties, Delrin is a Polyoxymethylene that was developed much later.

Thank you so much for putting this together. For a while I was only considering metal materials for a design I'm working on and then realized there's gotta be better, lighter plastic alternatives and needed a breakdown just like this to supplement my research. So thank you!!

Thanks or your video which is informative and clear. I want to select among pom, peek, Teflon. The part is immersed in 70c of water for a long time and it contact with a rotating shift. The part will be injection molding. Could accept tolerance +/-0.1mm. It is a rectangular in shape, will be inserted to core for 2nd molding. Mold temperature 130c. Plastic which cover onto the part meld temperature is 320c.

Thanks for the tips... I live in Brazil and I would like a tip, thanks which polymer among these or even uhmw w Teflon if I scrape on the asphalt will resist the most without wasting money, which has the greatest resistance to abrasion... For me this information is very important. Thanks Obrigado pelas dicas... eu moro no Brasil e gostaria de uma dica, qual polímero entre esses ou ate o uhmw w teflon se eu raspar no asfalto resiste mais sem gastar, que tem a maior resistência a abrasão ... Pra mim essa informação e muito importante . Obrigado

What would you typically use for an electronics enclosure? Like, let's say an industrial controller shell.

Can all of these materials be painted?

[samgong]

Very nice video. The conclusion at the end is awesome. For these plastic material, can we say that CNC and 3D printing are for prototype and the injection molding is for mass production?

[abhishekprasad]

how the fuck does such a good video dont have decent number of likes.!!
amazing explanation.

can Carbon fiber part replace by POM material,

[pjandryanadventuresruntime]

this was an excellent video, thank you for creating it. Which if the materials would be the closest in characteristics to 6061 aluminum (aircraft grade)? I was thinking of rifle stocks as a target application hence it should be stiff and non-brittle and not contract / expand within a reasonable band of temperatures (say -30 to +50 Celsius)

[ahmadmuammar]

Is there a way I could get the ABS surface finish ruler?

[mth]

what about hpde and uhmw plastics for cnc machining?

[Duraltia]

If only Delrin wouldn't be such a chemical resistant material it would be my immediate choice for my scale model projects but you can neither ( practically ) glue or paint it so yea... Mechanical parts use only ;(
