Michiel Dusselier, een bio-ingenieur van de KU Leuven, heeft de Eos Pipet 2016 gewonnen. Met die prijs bekroont het wetenschapsblad Eos de meest beloftevolle jonge onderzoeker van het jaar.
De jury looft de 30-jarige Dusselier voor zijn "inventieve oplossing om bioafbreekbaar plastic op een meer milieuvriendelijke en eenvoudigere manier te produceren".
Schoner, efficiënter en goedkoper
Het bioplastic polymelkzuur (PLA) wordt nu gemaakt van suiker. Het productieproces is echter omslachtig en een pak duurder dan de productie van klassieke plastics uit aardolie. De bio-ingenieur werkt met zeolieten (poreuze mineralen) die melkzuurmoleculen rechtstreeks kunnen omzetten in PLA-bouwstenen. Dat maakt dat de productie van PLA schoner, efficiënter en goedkoper.
Polymelkzuur wordt gebruikt in bijvoorbeeld groenteverpakkingen en composteerbare bekers, en is erg geschikt voor medische toepassingen en 3D-printing. Dusselier ziet vooral groeimogelijkheden voor het bioplastic in 3D-printing, omdat PLA niet stinkt. "Als 3D-printers voor thuisgebruik algemeen worden, ligt daar zeker een markt voor PLA", zegt de postdoctoraal onderzoeker aan de KU Leuven. Zijn onderzoek verscheen in het vakblad Science.

Hi all,
In the meanwhile I created another 21 grams object, a cube the size of 1 inch and the exact weight of 21 grams:
[print=4972][/print]
I thought this one was done, till I found this little platonic shape called a regular tetrahedron. This could possibly make the object even smaller (every side is 1 inch).
But now I'm in this pickle to find a suitable material to give it the weight of 21 grams.
Can anyone help me out here? This one is growing above my head
thnx a lot in advance.
-
Here you can find some answers to two questions: why 21 grams and why 1 inch:
- 1
-
will do SandervG, in time.
Right now I just discovered another possible shape for it, I'm in the middle of trying it out.
-
I recently made another study around the 21grams/1inch object:
[print=4972][/print]
-
thnx for the feedback all
I'll certainly have a go at these suggestions one day.
-
thanks for the tips, I'll maybe try them out one day.
But I'm still a bit reluctant with "overclocking" this machine
-
talking about fortune cookies,
maybe I can come up with something ...many thnx for the reaction meduza!
-
hihi kinda
I know this sound kinda weird, but I was just wandering around this, fragile multilayered filaments, that you ought to break to reach the inner layer sorta speak, a bit like a fortune cookie that you need to break before you see the message.
...if I make any sense lol
-
I'm on the lookout for a fragile filament, if it exists.
Not that fragile that it breaks while looking at it, but for instance when you squeeze your hand it would break, or when you let it fall on the ground.
Does such filament exist?
just wandering really, I'm brainstorming around some things.
-
Thnx Robert,
It does not really have to be a single material, so maybe that's another option indeed.
And I'll have a look at those other metal filaments for sure.

Hi there,
Right now I'm busy with a little art project called 21 grams dealing with objects that are having that exact weight.
To make things a bit more complicated it has to be a cube that is 1 inch (2.54cm).
Right now I'm printing a solid (colorfabb) white pla cube but it states it will be only 20 grams in cura. I'm kinda hoping that after the finish, it will arrive at the 21grams point, or that the tolerance will take care of things and it will turn out to be 21 grams after all.
Just in case these options do not work out. Are there by any chance heavier filaments available to work with?
I have no real experience with other filaments then pla so far. But I noticed CPE is a bit heavier?
Maybe with a heavier filament I can play with the infill settings to generate that weight, and size?
Any options in case this print does not work out is much appreciated.
-
thnx meduza, found it
-
Hi all,
Some time ago I had a cura version (can't remember which one) that included info on the weight of the piece.
I can't seem to find it on the newer versions though. Is there a way to see this info some way?
I'm planning to make some other pieces with a fixed weight.
-
many thnx, just figured out how to move material. Any way to move material without having to rotate the dial by any chance?
-maybe change filament, and when it extrudes the material just let it flow for a while?
-
Thanks for the reply all, isn't there a way to detach the nozzle to use it as a pen (just like the 3doodler)?
-
Is this possible?
I maybe want to recreate these sculptures with ultimaker:

Heck, another entry,
-
thnx sander, ooh, it's that easy? I used insert code and pasted it in there but that didn't do the trick
-
count me in for this one, or at least kick start it with this little thingy.

I tried embedding the code but it does not seem to work.

So you are paying for your own prize then.
it certainly feels that way. It left me rather stunned, not to mention quite disappointed. I really thought these prices were more content wise related.

Someone made the suggestion some time ago to enter competitions to receive some feedback around some designs I have made.
This is not really my style but ooh well, I looked into it a bit yesterday and it kinda blew me away... Alice in wonderland kinda style.
Turned out you have to pay an entrance fee, and now for the twilight zone part, you have to pay gigantic fees when you do win such a competition. O_o
Red dot, if design, you name it, they all do it.
So in my case I would pay for something and then hope to god that I don’t win that prize or I would go bankrupt lol
This is starting to get ridiculous if you ask me.
Or am I missing something here?
-
Thanks yellowshark, I'll certainly have a look at that option as well.
Soms drolletjes

Hey,
Als ik je goed begrijp wil je bvb een pyramide uitprinten en de punt ervan is een drolletje geworden?
Als dit het is, heb ik hetzelfde probleem, en dezelfde mogeljike oplossing.
Dit komt omdat hij mathematisch correct aan het printen is, maar de vorige laag is nog niet volledig droog zodat alles een beetje in mekaar stuikt.
Eén oplossing zou idd kunnen zijn om meerdere objecten tegelijkertijd af te printen, zodat er meer tijd onstaat tussen de opbouw van de verschillende lagen.
Maar zijn er misschien nog andere opties? Ik zou ze ook graag horen :-)
