I was asked to talk at LeWeb2013 in Paris!
It was a fantastic experience and I met a lot of great people.
More later, but for now, my presentation:
Winter is coming..
So to keep you warm, this years seasonal highlights:
It is our great pleasure to share free design files for personal use to the AWESOME maker community on this globe.
And the continuing thanks we receive, really means the world to us!
However, since “thanks” is not yet a valid currency 😉 we humbly ask:
Do you like/download or print one of our designs?
Then please consider a donation, any amount is welcome!
Donations do not give any rights for commercial use of our work.
And it does not change the CC license in any way, the designs are still only shared under CC-BY-NC-ND.
You will however gain my eternal gratitude for your support! 🙂
Donations not your thing? You can always show your support by buying something in my Shapeways Shop 🙂
So, business that bad, huh?
Well not really, but once you start sharing designs for free personal use, there is no real control over what people do with them.
And we, as well as many other designers, have been suffering from continued commercial abuse of our works by various parties.
Our CC-BY-NC-ND models or prints have been sold, used in product and company advertising and promotions without permission and often even without attribution.
It takes a lot of time, money and effort to get these things sorted out and financial compensation seldom happens.
For commercial use of any kind please contact us for licensing info and fees.
The commercial fees are very reasonable and allow us to produce more great designs for sharing.
Commercial use includes but is not limited to:
– Selling prints or pictures by either individuals or companies.
– Showing prints or pictures for promotional or advertisement purposes. (For example promotion of your filament, printer or service etc).
I have been polishing old and new to get the Winter 2013 Collection ready in time.
We will likely be flooded with posts about this:
Not a great, but a decent initial study I think.
But before the media hype impairs your judgment:
The main results of the article:
(removed references, those are in the full article)
“For comparison, our estimate of the total UFP emission rate for a single PLA-based 3D printer (1.9-2.0×1010 #/min) was similar to that reported during cooking with an electric frying pan (1.1-2.7×1010 #/min). The same 3D printer utilizing a higher temperature ABS feedstock had an emission rate estimate (1.8-2.0×1011 #/min) similar to that reported during grilling food on gas or electric stoves at low power (1.2-2.9×1011 #/min), but approximately an order of magnitude lower than gas or electric stoves operating at high power (1.2-3.4×1012 #/min). Regardless, the desktop 3D printers measured herein can all be classified as “high emitters” with UFP emission rates greater than 1010 particles per min”
“One important limitation to this study is that we have no information about the chemical constituents of the UFPs emitted from either type of 3D printer, although condensation of synthetic organic vapors from the thermoplastic feedstocks are likely a large contributor. In addition to large differences in emission rates observed between PLA- and ABS-based 3D printers, there may also be differences in toxicity because of differences in chemical composition. As mentioned, thermaldecomposition products from ABS have been shown to have toxic effects; however, PLA is known for its biocompatibility and PLA nanoparticles are widely used in drug delivery .”
So please try to read the full article yourself and draw your own conclusions 😉
Anyway, I never figured ABS fumes to be very safe, especially in cases of ABS gunk burning up on the nozzle.
PLA is of course a lot “safer” but I doubt it’s healthy when PLA gunk burns up at the nozzle.
And small amounts of plastic can create large amounts of fume/particles.
That said, I always advocate using printers in well ventilated rooms and/or use a filtered/ventilated enclosure for the printer itself.
A couple of years ago, I realized the first part of this project “Quarks”.
A line of science inspired jewelry, bases on the intricate motion of sub-atomic particles in magnetic fields, such as visualized in bubble chambers:
I simulated the motion of particles in magnetic fields and varied speeds, masses, charges and fields to create complex and elegant patterns.
But I got myself into some trouble there, the plastic at the time was a bit boring, many variations were not printable in metals.
And I found only few to be really good enough, but then people wanted earrings, bigger, smaller etc.
I was just not set up for that kind of demand, so I moved on for a while.
Then a couple of months ago, I wanted to revive this and make it work better and this is when I stumbled upon MixeeLabs of MixeeMe fame.
A match made in heaven 😀
And we are very proud that “Quark Jewelry” is one of the MixeeLabs launch projects!
Wow, what can I say, it has been a turbulent week indeed! Seems like good things still come in 3D’s!
Gyro the cube got featured
Earlier this week “Gyro the Cube” was featured in a round-up of
“10 3D printed objects that defy traditional manufacturing” over at 3dprinter.net.
Among nine other exquisite examples of 3d printing.
Then I got an email that one of my entries in the Figulo Ceramics challenge at GrabCAD had won!
I got featured!
And to top it off, I was really honored to be named in “A Showcase of Influential 3D Print Artists” over at Fabbaloo.com!
Major thanks to Chris Waldo from Kraftwurx and 3dprinter.net + fabbaloo.com for featuring this!
Also to Andy Jeff from Figulo, Kaspar Klis from GrabCAD.
And as always, the dream-makers at Shapeways!
Wow what a week!
Here is a quick video montage of some of models made with a pp3dp Up!
Still very happy 😀
