Hey y’all !
I totally agree with @sneyk 😀 that’s exactly the same process we have hehe
i just took some photos of some of our PS products, and when transparent PS is used, we see the “air?” bubbles you talk about, but the surface is smooth for us. You should really be sure to be excessive amount of plastic (and have an exit point for that excess)…[Read more]

Hello everyone,

Here is a little update to explain to you guys a new technique we discovered.

The output product is hollow tube made out of LDPE pallet wrap.

Needed material :
– 1 plancha
– heat protection gloves
– LDPE Pallet wrap (seperated into thin layers)
– a cylindric metal bar (cut it so that it’s length is smaller than the plancha…[Read more]

Hello Paul !
(since you asked me in MP too, i’ll just copy my answer here so it can benefit everyone)

I don’t think there is any way to decolorize plastics. The color of a plastic is due to the pigmentation additives it has in it.

I work it out the other way round; as i color ”transparent” plastic through addition of colored plastics (of same…[Read more]

heya 😀

i managed to do that in a multiple step process !

Print object in PLA.

Make a little wooden box, hollow in the top.

Put 3D printed (PLA) product in wooden box.

Fill the box with a thermoset resin (so heat doesn’t impact the moulding process); i am sorry i can’t recall which resin was used, but it can be found “more or less” easily in…[Read more]

i really have to insist on the SLOWNESS of the degradation process.

We baught approx 200 larvas; they are living through their 5th or 6th cycle now; and are still eating the same expanded polystyrene we put almost 7 months ago.

VERY VERY SLOW process ! (but interesting nonetheless :p)

sorry for bad photo quality 🙁

happy tenebrions doing there thing 😀

hello @edwardmartinhill,

PET is very sensitive to 2 types of degradation :

– Hydrodegradation is caused by presence of humidity or water (H20) while trying to melt. The H2O breaks the PET bonds to form other chemical bonds.

-thermodegradation is caused by being at too high T° or too long at high T° (while already being melted)

I don’t think y…[Read more]

Hey there @ianrobbo !

bottle caps will “always” be PP or PE (which are from same family Polyolefin).
in order to have best quality of product output, i would recommend only using “food-grade” bottle caps, as the types of additives in them should be limited.

concerning the granulated PET/PP mix, from my point of view you won’t be able to do…[Read more]
