Was een beetje onbesuisd om Arcam af te dekken met DDD.

Dat werkt niet.

Als Arcan daalt en DDD stijgt werkt het dubbel in je nadeel.
Het is een beetje het verhaal van appels en peren.

Afdekken van appels met peren.
Niet doen dus.`
te
Nu de koers van Arcam daalt en die van DDD stijgt is de vraag wat doen,

Ik kies voor DDD maar wacht nog af.

Groet.

German team 3D prints micro trusses as strong as steel but lighter than water

Computerworld reported that a team of German scientists used 3D laser lithography to print microscopic trusses and shells that are as strong as steel and lighter than water.

The honeycomb like structures, made of ceramic polymer composite material are only about 50 nanometers thick.

The German team recently published a paper on their research. Mr Jens Bauer, a materials scientist leading the research at the Karlsruhe Institute of Technology in Germany, in the paper said “The polymer composites exceed the strength to weight ratio of all engineering materials, with a density below 1,000 kilograms per meter.”

Mr Bauer stated that “The scientists took their inspiration from nature, which has produced materials far stronger, yet less dense than those created in a lab. For example, natural cellular materials such as bone and wood are strong and yet have considerably lower densities than aluminum alloys.”

He added "Applying 3D laser lithography, which allows for producing almost arbitrary structures with sub-micron resolving power, micro-truss and shell structures may be manufactured. Ratios comparable to those of advanced metallic alloys or technical ceramics have been obtained."

The team used a 3D printer from Nanoscribe GmbH. The Nanoscribe Photonic 3D Professional printer from Nanoscribe GmbH, is a table top laser lithography system used for creating three dimensional photonic structures

The nanostructures are created by placing a small amount of photocurable resin on a glass slide. Then a stereolithography 3D printer projects a laser in a grid like pattern on the liquid material, hardening it where the light strikes. The resulting hardened structure is then coated with alumina, or aluminium oxide.

Nanoscribe's stereolithography 3D printers are unable to as yet create structures larger than micrometers in size.

10 industries 3D printing will disrupt or decimate

For better or worse, the 3D printing industry is poised to transform nearly every sector of our lives and jumpstart the next industrial revolution. Sound like a hyperbole? We've compiled a list of 10 major impacts the 3D printing ecosystem will have on businesses, consumers and the global economy.

If you're just diving into the world of 3D printing, first take a look at my introduction on 3D printing industry basics to quickly get up to speed: 10 facts on 3D printing: Understanding tech's next big game changer.

1. Massive environmental impacts
Traditional manufacturing is often wasteful and dirty. In many ways, 3D printing lessens that waste and the carbon footprint manufacturing has on the Earth.
(I). Fewer wasted materials: Only the raw materials needed to create the object be it plastic filament, metal powder, or carbon fiber are used. Using biodegradable PLA plastic filament in fused deposition modeling printers like MakerBot is a good start.
(II). Possibility of longer life spans: Product parts can be replaced with 3D printing (or at least, that's the idea for the future), so the entire product doesn't have to be thrown away and replaced each time it malfunctions.
(III). Less transport: Products often travel across many continents to get to their final destination. With 3D printing, the production and assembly can be local. Raw materials are the only things that will ship, and they take up far less space.
(IV). Fewer unsold products: If a company makes a product, the ones that are discontinued or not sold often end up piling up in landfills. 3D printing can improve this because companies can make them as needed.

This is all great in theory, but research shows 3D printers themselves have inefficiences that make them less environmentally friendly. An inkjet 3D printer wastes 40% to 45% of its ink. And if a printer isn't turned off or unplugged, it uses an excessive amount of electricity. As the printers become more accessible, manufacturers will need to figure out how to improve these issues.

2. Creating a new art medium
The maker movement is getting more niche now we can call it the artisanal movement. 3D printers are being used to create new types of modern art, like this 3D headdress created by artist Joshua Harker, which debuted at 3D Printshow in New York City. The printers can also recreate pieces that aren't accessible to everyone around the world, which helps museums. For instance, the Van Gogh museum in Amsterdam has teamed with Fujifilm to recreate 3D replicas of several Van Gogh paintings.

3. Innovation in education
Mr Bre Pettis CEO of MakerBot said in the announcement said that “A few months ago, MakerBot announced MakerBot Academy, a crowdfunded plan to get a 3D printer into every school in America. It can change the whole paradigm of how our children will see innovation and manufacturing in America. The company also recently announced a plan to turn colleges and universities into MakerBot Innovation Centers. Starting with State University of New York at New Palz, the centers are equipped with 30 3D printers along with several 3D scanners to help train engineers, architects, and artists and increase motivation for growth in the industry.”

4. 3D printing in zero gravity
One of the most logical uses for 3D printing is printing parts, tools and other gadgets for astronauts while they're in space. It can also help accelerate the building of parts for the International Space Station. To address these problems, Made In Space was formed by a group of space veterans and 3D printing enthusiasts. They have partnered with NASA's Marshall Space Flight Center to launch the first 3D printer in space. It will manufacture parts in zero gravity and the hope is to make space missions more self sufficient. On a related note, an engineer won a grant from NASA last year to prototype a machine that will print food that's better than the freeze-dried stuff astronauts normally eat.

5. Revolutionizing mass manufacturing
Mass production is the biggest challenge in 3D printing, but with the adoption of large-scale printers and rapidly evolving technology to produce parts faster, the printers will completely disrupt traditional manufacturing in many industries:
(I). Food: Anything that exists in liquid or powder form can be 3D printed, so naturally, printed food is one of the next big conversations.
(II). Military: The machinery for the military is often customized and replacements must be made quickly. A 3D gun has already been printed, so it's only a matter of time before the technology catches on in this industry.
(III). Electronics: The size, shape, and materials used to make electronics make this industry a natural candidate for 3D printing.
(IV). Toys: Home 3D printers and open source design will change the way children create and play.
(V). Automotive: This industry is already utilizing the technology Ford reportedly uses 3D printing to test parts. High end and smaller auto companies will benefit first, though 3D printing could improve the efficiency of making replacement parts for any company.

6. Changing medicine and healthcare
Bioprinting is one of the fastest growing areas of 3D printing. The technology uses inkjet style printers to make living tissue. Organovo, the most well known company who does this, plans to commercialize 3D-printed liver tissue sometime this year. They have also partnered with the National Eye Institute and the National Center for Advancing Translational Sciences to print eye tissue. Researchers at Human Methodist Research Institute said they have created a more efficient way to create cells. Called Block Cell Printing, this process allows 100% of the cells to live instead of the 50% to 80% that normally survive during the current process. All of this naturally raises questions about the development of complex organs, so bioprinting is destined to turn into a big debate due to moral, ethical and political concerns.

7. Transforming the home
Humans love their home conveniences and home 3D printers are becoming smaller and more affordable MakerBot's smallest printer is just over USD 1,300. People can print custom jewelry, household goods, toys and tools to whatever size, shape, or color they want. They will also be able to print make replacement parts right at home, rather than ordering them and waiting for them to be shipped. According to research firm Strategy Analytics, home 3D printing could evolve into a USD 70 billion industry per year by 2030.

8. Reaching disconnected markets worldwide
Developing countries are often completely disconnected from global supply chains for even the most basic products, but 3D printing has the ability to bring them into the loop. The best example of this is Austin based startup re:3D, which had a hugely successful Kickstarter campaign last May with Gigabot, an industrial sized, affordable printer designed to work in developing countries. The company has a localized presence in Latin America, specifically partnering with StartUp Chile, a Chilean government program that empowers local tech entrepreneurs. The Gigabot will be used for many of the projects in Chile, like 3D design internships, manufacturing clothing, and experimenting with printing using recyclable materials.

9. Impacts on the global economy
The 3D printing industry will have far reaching effects on the global economy. McKinsey Global Institute recently released a report that said 3D printing will cause major disruptions in the global economy by 2025. The analysis firm predicts it will bring about new product development cycles as the systems become cheaper. More companies will adopt the technology and product creation will focus on client feedback and customer centered design. The industry is also reducing the cost of of entry into markets, allowing very niche businesses to pop up everywhere.

10. Intellectual property threats
Sharing 3D printing schematics on websites like Thingiverse and Shapeways seems easy enough, but free designs are bound to cause issues with intellectual property as 3D printing becomes more mainstream. Most of the designs are unpatented so they can be copied repeatedly and sold by anyone. Expensive or designer objects can also be reverse engineered or replicated and sold at a cheaper price.

Now, established companies are starting to go after users of these sites, arguing that they are infringing on copyright or violating intellectual property laws. However, most of these designers are building upon original designs, making them better, or localizing products to better suit the needs of people in their area. It will be an ongoing conversation. The industry will have to figure out how to make sure large corporations don't squash entrepreneurs and designers in their fight to protect copyright laws.

3D printing - 10 factors still holding it back

Yes, 3D printing stands to completely transform the way we make, replace, and transport products and will disrupt nearly every major industry. However, the technology is still geared toward passionate, motivated makers and hobbyists not the average citizen. We've compiled a list of 10 reasons 3D printing hasn't quite caught on yet and what is holding the technology back.

1. Awaiting the breakthrough consumer model;
Widespread consumer adoption will depend on 3D printers dropping in price. Currently, printers less than USD 1,000 use a DIY style kit that requires assembly of the machine itself and they often don't replicate the CAD designs accurately. But, relatively cheap 3D printers do exist. At USD 299, the Printrbot Simple is an affordable option, though it is very basic and can't print high quality products. Also well under USD 1,000 is RepRap's open source line of printers, which have to be assembled separately. The Cubify Cube is about USD 1,300 and probably the best desktop option since it connects to wifi but its plastic filament can't make anything too sturdy.

2. Expense of SLS printers;
Major patents on selective laser sintering printers expired in January, so perhaps the prices of these machines which run as high as USD 250,000 will decrease. When the patents on fused deposition modeling printers expired, there was an explosion of open source FDM printers that led the technology to become a hobby. The best example was MakerBot, which launched as the most well known FDM printer almost immediately after the FDM patent expired.

3. Patents and legal murkiness;
This year, many patents on 3D printers will expire, possibly creating more competition, innovation and lower prices. However, there are still quite a few overlapping patents out there however, which causes a lot of murkiness. During the last decade, the Patent and Trademark Office has received more than 6,800 3D printing patent applications. Since 2007 almost 700 patents have been filed annually. Another intellectual property issue comes with what the machines are printing. Right now, it's easy to log on to Shapeways and download a CAD file of just about anything. But soon, there will be lawsuits and competition between brands over knockoffs and copyright infringement.

4. The usefulness gap;
Sure, plastic action figures, iPhone cases and Star Wars themed novelties are fun to design and print with a relatively affordable desktop 3D printer like the Cube, but they aren't exactly impactful on our everyday lives, nor are they convincing consumers the machines are a worthy investment.

Mr Pete Basiliere lead Gartner analyst for 3D printing said that “There's no compelling application in the present time because anything you can print on a 3D printer, besides from things that are truly customized, you can buy at a store. A compelling consumer application something that can only be created at home on a 3D printer will hit the scene by 2016.

5. Plastic filament isn't sturdy enough;
For the foreseeable future, the cheapest and most accessible 3D printers will be FDM. These are the desktop printers that use PLA and ABS plastic, which easily melt and fit small molds. However, the plastic isn't sturdy and not many household products with moving parts can be created from the material. Printers will need to use carbon composites or metals to become more useful to the average consumer, as well as manufacturers.

6. That 3D-printed gun;
Before the majority of Americans could wrap their heads around how 3D printing works, a man named Cody Wilson designed, printed and successfully fired a 3D printed gun. The STL file was available for free on his website the next day and 100,000 people downloaded it before the US Department of State ordered him to take it down. Since an all plastic 3D gun probably won't catch on, other companies are working on using SLS technology to print a metal one. So, in December 2013, Congress voted to renew an expiring ban on plastic firearms that could slip past metal detectors, though it didn't add any new restrictions on plastic guns. Philadelphia was the first city to ban 3D printed firearms. A Chicago lawmaker wants to make it illegal to use a 3D printer to make gun parts unless the user has a federal gun manufacturer's license.

7. 3D printers aren't that user-friendly;
Setting up a 3D printer will need to be as easy as hooking up a traditional HP printer. The 3D printer needs to have fewer wires than a television and fewer buttons than a computer for it to become a household electronic, and right now, that's not the case. The printers use high-voltage power supplies and specialized equipment and parts. Some of the cheapest printers can't even connect to wifi and most have low resolution.

Because of the hype around the potential and the cute plastic toys that they produce, 3D printers have come across as easier and more useful than they actually are. The best products that have been created think tools, musical instruments, car parts are made using huge, high end printers that cost hundreds of thousands of dollars. Those sub USD 1,000 machines that sit on a desk just aren't going to be as productive.

8. Complex design software;
Downloadable files from Thingiverse and Shapeways are easy to get but they are not moderated and therefore may not work on every type of printer. If you want to design your own file, you need a working knowledge of CAD design. Setting up the model and using the printer takes quite a bit of patience and time, which is another reason the technology has primarily been used by enthusiasts up to this point.
9. 3D printers are still slow;
3D printers are great for mass customization, but are still too slow for manufacturing lots of objects. To change the manufacturing industry, the parts need to be printed in minutes, not hours. It currently takes anywhere from several hours to several days to print, depending on the size of the model and the quality of the printer. Receiving an order from Shapeways, the company that customizes and 3D prints a variety of products, can take up to two weeks, depending on the materials used.

10. Safety concerns;
The FDM printers, which use plastic filament, are relatively safe to use they are often made for desktops and contain both the mold and the residue but they aren't foolproof, and they reach very high temperatures. Powder based printers are messy and potentially explosive depending on what is being made from them. They operate at extremely high temperatures and produce waste. It's not something a consumer would want in their home office. Indoor air quality and the emissions from 3D printers, particularly SLS printers, are also cause for concern.

Wat is jouw visie op arcam? Koers doet het niet best de laatste tijd.

Veel informatie krijgen we niet, maar er wordt hard gewerkt om de printsnelheid en nauwkeurigheid te verhogen.
Het blijft een marktleider met veel patenten. Heeft een flinke vinger in de toelevering van de print grondstoffen.
Veel kansen.
In mijn visie is het wachten op de melding van meerde orders voor systemen.

De vraag naar metal printing groeit sterk vanuit de industrie, en zeker binnen Europa.

Daarom denk ik dat wanneer het tegenzit voor Arcam, er toch een groei zal zijn van 10% per jaar voor de eerstkomende vijf jaar.

Indien de ontwikkelingen goed uitpakken, voorzie ik een groei van 40 tot 50% jaar op jaar voor de komende twee jaar.

Ik kijk iedere ochtend even op de site om het nieuws te volgen.

10 facts on 3D printing: Understanding tech's next big game-changer

The world of 3D printing is exciting. With more affordable machines, creative entrepreneurs, innovative startups and new materials, the industry is rapidly evolving.

Since the invention of the 3D printer in 1983 by Chuck Hull of 3D Systems, companies have popped up all over the globe, attempting to make the most innovative machine. Here are 10 reasons why 3D printing matters maybe you'll decide the equipment is a worthy investment, or maybe you'll just be convinced this futuristic technology will one day have a place in your business or home.

1. 3D printing is a key industry to watch in 2014;
Enthusiasm is high and so is the market for 3D printing in both consumer and enterprise space. According to Gartner research, printers under USD 100,000 were expected to grow almost 50% in 2013, and will increase 75% this year. Right now, enterprises are using the printers to prototype objects, but we'll see an increasing amount used to make product designs this year.

2. 3D printers are empowering makers;
Mr Chris Anderson former editor in chief of Wired, wrote in his book, Makers, that a new industrial revolution is underway because of open source design and 3D printing. Many entrepreneurs are using micro manufacturing to create smaller batches of customized products. And with crowdfunding sites, they don't have to rely on venture capitalists to fund these endeavors.

3. Customization is the next step in 3D printing technology;
Mr Pete Basiliere lead Gartner analyst for 3D printing said that “Soon enough the question won't be how we will print things, but what we will print. Customization is the next buzzword in the industry. Replacement parts, toys, and random designs and schemiatics found on the internet can all be customized to fit consumer needs. Because the machines can print one piece at a time, this can be done relatively easily. Shapeways, for instance, is a website where customers can connect with designers and order customized products such as jewelry and home decor.

4. There are several types of 3D printing technologies;
Fused deposition modeling: MakerBot is one of the best examples of this technology. These printers melt a plastic filament and deposit the plastic in layers until it fills up the model. There are two types of plastic both of which MakerBot uses: ABS which is sturdy and made from oil based resources and PLA, which is biodegradable and made from plant based resources.
(I). Stereolithography: These machines use a laser to cure a resin and build the prototype one layer at a time. Rapid prototyping, another form, doesn't use supports to hold up the part so that it can be built faster but in basic stereolithography, the supports must be manually removed from the part.
(II). Selective laser sintering: Lasers are used to sinter powdered metal, binding the powder together to create a solid structure. After each layer is sintered together, the structure drops and the next layer is built on top of it.

5. People are making all kinds of things with 3D printers;
Check out Makerbot's Thingiverse the things people create with 3D printers are extraordinarily creative. It's a community for makers where they can upload digital designs or photos of objects they have made with 3D printers. The website has more than 100,000 models and that number is growing every day. From Storm Trooper pen cups to household planters to customizable necklaces, the options of objects people can make are seemingly endless.

6. Ethical dilemmas of 3D printing will be a growing conversation;
Get ready for it the next great debate will be about the political, ethical and religious questions 3D printing technologies raise. This is particularly important for bioprinting, which is already accelerating at an alarming rate. Scientists at Cornell University successfully printed a human ear last year, and scientists in Scotland are developing a way to print embryonic stem cells. Another issue is weapons. In 2012,a man 3D-printed a gun and shared the blueprints on his website (they garnered 100,000 downloads in the two days before the US State Department took them down). He successfully fired it last year, landing himself onWired's list of deadliest people on the planet.

7. Lower prices will drive consumer adoption;
As smaller companies make their own 3D printers or crowdfund them, the prices are going to continue to drop. Already, Makerbot's smallest printer which will begin shipping this spring is available for USD 1,375. That still seems pricy for a lot of us but it's quite affordable for the technology.

8. HP is going to get in the game at some point;
The 3D printing leaders are making themselves known, but there's an elephant in the room: when will HP join the ranks and produce this technology for the mass market? The traditional printing giant has a five-foot-tall 3D printing prototype in the basement of its Palo Alto research lab, and the company said they plan to release a product this year.

9. 3D printing is going to completely revolutionize manufacturing as we know it;
Open source electronics allow companies to iterate designs and experiment with schematics and product parts. Eventually, they won't need to design every piece in house and they won't need to ship every part because local or regional makers can design and print the parts themselves. Big supply chains will be a thing of the past. Most companies aren't grasping this technology yet because it's going to change the industry so dramatically. According to Basiliere, the key to long-term growth in the manufacturing industry is the number of materials 3D printers can use, which is small but growing quickly as well.

10. 3D printing is going to cause disruption in many industries;
We know 3D printing will upheave mass manufacturers, but what else will the technology affect? Well, just about everything. Educators can print tools or designs in schools. Artists will have a new medium to work with. Healthcare providers can quickly create what they need in-house. Parents will be able to replace toys or broken household items in a matter of hours.

Van Forbes:

Why Is HP Entering 3D Printer Market Now?

HP is a leader in the 2D printer market, and its market share was nearly 40% in 2013 according to IDC. The company believes that 3D printing is a natural progression of its 2D printer business, where it has a sizeable share. In its shareholders meeting held last week, HP announced that it has plans to enter the commercial 3D printing market by the end of this fiscal year. The main reason why HP is entering the 3D printer market now is because a host of core patents such as apparatus for producing parts by selective sintering have either expired or are expiring within a year. As a result, HP won’t have to spend huge amount of time and money on developing new technology and processes for discovering how to model 3-D objects. Furthermore, the high cost of consumables in 3D printing has been a major barrier to innovation in the field. However, HP claims to have solved a number of technical problems such as low quality print output and long printing time that have hindered broader adoption of the high-tech manufacturing process.
