ExOne drukt de koers van de markt nog wel even (ExOne missed earnings) maar Arcam krijgt meer potentie.
Fool artikel van 6 maart is dacht ik nog niet geplaatst hier.

Geeft expliciet aandacht aan metal printing (laser vs EBM) en potential van Arcam.
Er wordt een targetprijs voor Arcam genoemd van 300 SEK. Al met al denk ik dat er weinig neerwaarts risico is vooor Arcam... (disclaimer van toepassing!)
Lijkt me niet verkeerd, onduidelijk is echter of laser sintering niet goedkoper is dan EBM
In dit artikel wordt een nieuwe speler genoemd: renishaw. (very) Small cap op de Uk beurs.
Iemand bekend met dit bedrijf?

Verder info over verschillen tussen laser sintering en EBM. EBM schijnt snelr te zijn.
Renishaw is een klein bedrijf, met name gespecialiseerd in dental.
Metal printing van frames en bruggen.
Alphaform is interessanter, heeft veel meer know-how.
Disclosure: I own shares of Alphaform AG.
Gary Anderson.

Netjes dat hij het er altijd bij zet. Wel een beetje risico van het Geert Schaay-effect.

Bovenstaande quote is aangevuld met krsen 21/3-2014.

Vjet shorts gesloten,Exone wss 24/3.En DDD laat ik nog even......
In overweging: open sell Vjet puts aug 25 aan 5.00(bij krs < 28)

PS: artikelen over fusie/overname gedachten zijn ,imo, fantastische stories.
Ik ga ervan uit dat er in 2014 geen M&A aktiviteiten komen. kww.....
DDD gaat nog niet door het putje
Ik heb er geen belang in
Maar toch ben ik blij dat Seeking Alpha niet alles bepaalt, net als die basher van Citron die alleen maar beleggers uitperst met extreme opmerkingen
Local Motors 3D printed electric cars

Local Motors doesn’t like to do things the normal way. The car company based around an online community of consumer-designers is once again trying to shake up the manufacturing process with a 3D printed electric car.

Local says this will be the first 3D printed electric car and it plans to build it right on the floor of the 2014 International Manufacturing Technology Show in Chicago this September.

While it’s not the first to conceive of a 3D printed car, Local seems like the ideal company to harness the technology.

The main advantage of 3D printing in an automotive context is flexibility. Since tooling won’t have to be created for individual parts, changes can be made more easily to the design.

This plays right into Local’s community based method. The company seeks input from potential customers, who can vote on different aspects of the design. It worked pretty well for the Rally Fighter off road performance vehicle that’s currently in Local’s catalog.

The lack of tooling could also speed up the transition from design to production and give designers more leeway.

Of course, Local won’t build its car by feeding spools of plastic into a desktop Replicator.

The company plans to use a hybrid additive/subtractive machine that’s been demonstrated at Oak Ridge National Laboratory. It can print out an object (addition) like a normal 3D printer, but also has a router attachment that can remove material (subtraction) like a machine tool for more precise shaping.

The exact shape that will come out of that machine is still up in the air.

Local said that the car will be purpose built for the urban transportation needs of Chicago but hasn’t revealed any specific information about it. That will have to wait until the 2014 International Manufacturing Technology Show, which runs September 8th to 13th.

Perhaps then we’ll see if the future of the car will come out of a printer, or if robots and stamping machines will always reign supreme.

The dark side of 3D printing - 10 things to watch

As with any new technology, it's easy to get swept up in the benefits of 3D printing. It opens up a world of new possibilities for all industries and stands to lessen transportation costs, environmental impacts, waste and reliance on corporations by enabling the maker movement.

But 3D printers are still potentially hazardous, wasteful machines and their societal, political, economic, and environmental impacts have not yet been studied extensively. To make sure you aren't thrown off guard by the conversations to come, we've compiled a list of 10 things you need to know about the dangers and potentially negative impacts of 3D printers.

1. 3D printers are energy hogs;
According to research by Loughborough University, when melting plastic with heat or lasers, 3D printers consume about 50 to 100 times more electrical energy than injection molding to make an item of the same weight. In 2009, research at MIT's Environmentally Benign Manufacturing program showed that laser direct metal deposition (where metal powder is fused together) used hundreds of times the electricity as traditional casting or machining. Because of this, 3D printers are better for small batch runs. Industrial sized 3D printers may not be the answer to lessening our use of coal power any time soon.

2. Unhealthy air emissions;
According to researchers at the Illinois Institute of Technology, 3D printers may pose a health risk when used in the home. The emissions from desktop 3D printers are similar to burning a cigarette or cooking on a gas or electric stove. The 2013 study was the first to measure these airborne particle emissions from desktop 3D printers. While heating the plastic and printing small figures, the machines using PLA filament emitted 20 billion ultrafine particles per minute and the ABS emitted up to 200 billion particles per minute. These particles can settle in the lungs or the bloodstream and pose health risk, especially for those with asthma.

3. Reliance on plastics;
One of the biggest environmental movements in recent history has been to reduce reliance on plastics, from grocery bags to water bottles to household objects that can be made from recycled materials instead. The most popular and cheapest 3D printers use plastic filament. Though using raw materials reduces the amount of waste in general, the machines still leave unused or excess plastic in the print beds. PLA is biodegradable, but ABS filament is still the most commonly used type of plastic. The plastic byproduct ends up in landfills. If 3D printing is going to be industrialized, that byproduct or other recycled plastic needs to be reused.

4. IP and licensing deals;
In January, 3D Systems acquired Gentle Giant Limited which owned the licensing rights to toy franchises such as The Hobbit, The Walking Dead, Harry Potter, Alien, and Star Wars. Gartner has said that companies may lose at least USD 100 billion in four years to licensing or IP owners. 3D printing will change the business market and the black market for these items and the legislation will have to rush to catch up. This potential digital piracy situation is comparable to the way the internet challenged the movie and music industries for copyrights, trademarks and illegal downloads.

5. Gun control loopholes;
The first successful 3D printed gun is old news, but its ramifications are very important. Companies are popping up around the world, attempting to sell these guns and the CAD designs for them. Engineering firm Solid Concepts has even fired rounds out of the first 3D printed metal gun. Congress' Undetectable Firearms Act, which bans guns that can't be detected by metal detectors or x-ray scanners, was renewed for 10 years. It left a loophole in the law, however: 3D printed guns with a tiny piece of metal aren't banned by the Act. Legislators are attempting to close that loophole now, after Congress ignored the issue for quite some time, with special requirements for printed guns.

6. Responsibility of manufacturers;
Weapons can be 3D printed. So can safety equipment such as helmets, wheels for bikes, and toys for small children. Of course there is the issue of intellectual property and trademark, but the larger issue involves responsibility. If a person shoots a gun and harms or kills someone, stabs someone with a 3D printed knife, or breaks their neck while riding on a bike with a 3D printed helmet, who is held accountable? The owner of the printer, the manufacturer of the printer, or the irresponsible person who thought it was a good idea to produce and use an untested product?

7. Bioprinting ethics and regulation;
The conversations about the ethics of bioprinting have already begun. Organovo is printing liver cells as well as eye tissue cells in a partnership with the National Eye Institute and National Center for Advancing Translational Sciences. Scientists have also proposed mixing human stem cells with canine muscle cells to create enhanced organ tissue. Printing cartilage is still the most realistic type of bioprinting, and printing whole organs is still many years away, but 3D printing is growing in medicine quite rapidly. Conversations about the moral, ethical, and legal issues surrounding bioprinting have started, but they will inevitably cause a lot more controversy as it becomes more commonplace.

8. Possibility of 3D printed drugs;
Assembling chemical compounds on a molecular level using a 3D printer is possible. A researcher at the University of Glasglow created a prototype of a 3D Chemputer that makes drugs and medicine. He wants to revolutionize the pharmaceutical industry by allowing patients to print their own medicine with a chemical blueprint they get from the pharmacy. Of course, this is a very long way off, but it stands to enable DIY chemists to create anything from cocaine to ricin.

9. National security risks;
A white paper released from the National Defense University highlighted national security risks from 3D printing technology. Since there will be significant legal and economic implications on the business sector and 3D printers offer the ability to produce a wide range of objects that cannot be controlled yet, the paper noted that there are definitely national security risks that need to be analyzed in the near future.

Ongeveer hetzelfde verhaal bij de doorbraak van de T Ford.... Levensgevaarlijk!

Net een vrouw verlost van haar tijdelijke blindheid door een geprinte schedel.
Toppie hè die jongens in Utrecht

p.s. geen tien punten maar negen.
De laatste vier punten gaan over de angst (van de schrijver) dat alles gemaakt kan worden?!
Punt 1; noemt alleen laserprinting; EBM gebruikt veel minder energie
punt 2; is waar bij het printen met kunststof binnenshuis (afzuiger aan)
punt 3; gelul, geldt ook voor plastic Ikea bekers
Punt 4; Ja, je kunt nu Barbie en Superman printen zonder patentrechten te betalen. Foei!
