3d printed interactive speakers by Disney Research

Disney Research is rely pushing many new inventive 3d printing technologies and projects. Looks like the next generation of toys will be 3d printed.
This is a 3d printable speaker that can reproduce hearable sound and interact with your computer by emitting a sound that human hearing can not perceive.

From video description:
Yoshio Ishiguro, Ivan Poupyrev


We propose technology for designing and manufacturing interactive 3D printed speakers. With the proposed technology, sound reproduction can easily be integrated into various objects at the design stage and little assembly is required.
The speaker can take the shape of anything from an abstract spiral to a rubber duck, opening new opportunities in product design. Furthermore, both audible sound and inaudible ultrasound can be produced with the same design, allowing for identifying and tracking 3D printed objects in space using common integrated microphones. The design of 3D printed speakers is based on electrostatic loudspeaker technology first explored in the early 1930s but not broadly applied until now. These speakers are simpler than common electromagnetic speakers, while allowing for sound reproduction at 60 dB levels with arbitrary directivity ranging from focused to omnidirectional.

Disney will 3d print your felt teddy bear

Disney Research released this video and paper about 3d printing soft felt structures with active components such as electronics. They basically show how to 3d print a high tech felt teddy bear or other soft toys. Mehtod could be described as additive 3d knitting.
The machine they are doing it on looks like DIY printer type machine, however I don't think they will open source it.
It is possible this will be commercialized ...

Stalactite 102 HD DLP foldable 3d printer from Spain

New high definition DLP 3d printes comes from Barcelona, Spain. It also features different resin types like wax resin suitable for lost casting.

Stalactite 102 specifications:
  • Minimum layer thickness down to 25 microns (hardware can support layers as thin as 10 microns).
  • High DPI (dot per inch) density on the X/Y plane (100 microns NORMAL mode, 50 microns FINE mode).
  • High quality precision components.
  • Mechanized aluminum and laser cut steel components.
  • Innovative decoupled dual peeling system (patent pending)
  • Proprietary software with fast slicing and automatic supports.
  • Wide choice of printing materials: currently up to 4 different resins with a variety of properties.
  • Build Area: 102mm x 76,8mm x 180mm
  • It will be priced at 2.895€ (plus VAT where applicable) when available for direct pruchase 

They have also developed a palette of resins with different properties and applications:
  • STANDARD: Entry level resin. Affordable and suitable for general 3d printing needs, from figurines to maquettes or quick prototypes.
  • PROTOTYPING: A hard and thought material, aimed at print objects that require improved physical properties. It has similar properties as ABS or Nylon plastic. Ideal for electronic housings, cogs, Iphone holders
  • ELASTIC: A resin with very peculiar properties: It's elastic and flexible. This opens up a world of options for your prototypes and props!
  • WAXY: It demonstrates similar properties to investment casting waxes. Once you print your model you will be able to use the lost wax investment process and cast your designs to bronze, silver, gold or any meltable metal. This resin is particularly well suited for jewelers and miniature figurines manufacturers.
They claim their DLP technology is superior to laser based resin 3d printers because:

  • Resolution: With DLP (Direct Light Processing) we can reach feature details of 50 microns, which is a six-fold improvement compared to Laser 3d printers that are limited by the geometry of the Laser beam (pointer diameter, varying shape, focus and raster speed).
  • Build Times: The Stalactite 102 builds each layer within a constant exposure time, making the size of the object within the X/Y build area independent of the build time. It doesn't matter how many objects you fit within the build area, print times will always remain the same, depending solely on the number of layers in the Z-axis. There's no rastering time, no head or pointer movement process, as is prevalent in the FDM, Inkjet and Laser 3D printing technologies.

Stalactite is currently on Indigogo, ypu can get it at much lower price:

RotoMAAK bridging the gap between 3d printing and fast manufacturing

RotoMAAK is DIY rotational casting machine that can produce casted resin models fast. Molds can be made from 3d printed objects, so you can produce small series very fast.

From Kickstarter description:
The RotoMAAK

Rotational Casting, also known as Rotocasting or Hollow Casting, is a molding process for creating many kinds of items, mostly hollow in form and typically made of plastic. The RotoMAAK rotocaster was born out of the desire to have a process by which Makers could scale up production of parts using rotational casting technology when 3D printing a small production run becomes cost and time prohibitive.
The RotoMAAK rotational caster consists of a hollow mold and a rotational device that spins the mold in a uniform motion. The hollow mold is filled with a charge or shot weight of air cure resin. It is then inserted into the RotoMAAK where it is slowly rotated (usually around two perpendicular axes) causing the liquid resin to uniformly disperse and stick to the walls of the mold where it slowly cures over time into the shape of the part. In order to maintain an even thickness throughout the part, the mold continues to rotate at all times during casting phase and curing phase. The continuous rotation of the mold also avoids sagging or and part deformation.
The rotocasting process was applied to plastics in the 1940's, but in its early years was rarely used due to a slow process and restriction to a small number of plastics. Over the past two decades, improvements in process control and developments with air cure resin and plastic powders have resulted in a significant increase in its usage for part production.
The RotoMAAK rotational casting machine allows the hobbyist to experiment with different casting materials and mold creation for production scale-up of parts to meet customer needs. With the popularity of DIY 3D printing, you now have the ability to create a 3D object in a relatively short amount of time compared to the traditional prototyping or one off manufacturing processes. 3D Printing allows you to create one part faster than traditional processes, but not reproduce it as quickly as mass manufacturing technologies. With rotational casting, you have more options to reproduce many identical parts from a successful print. Additionally it is not limited to 3D printed molds (NO 3D Printer required!), you can create a mold from almost any part and in turn reproduce multiple replicas of that item.
One of the major advantages of rotocasting a hollow part is the savings in materials and weight. If a part's function does not require it to be solid, why cast it solid and waste materials? Instead of using pounds of material to cast a solid piece, you can cast it hollow with ounces of resin, which in turn yields a big cost savings in time and material.
The RotoMAAK also controls the rotation of the mold to ensure a uniform wall thickness that rotating a mold by hand cannot achieve. Some air cure resins,especially the clear varieties, have a cure time of several hours instead of 6-10 minutes. Evenly rotating a mold for hours would prove to be impossible by hand, and a rotational machine like this will allow you to rotational cast clear bottles, glasses, etc. for amazing special effects.
First we were looking at ways to increase the speed of reproducing 3D printed parts, either by using a mold that was 3D printed and cast directly from that, or by 3D printing your part and creating a silicon mold from that. However, after talking to many people at Maker Faires, other Makers and hobbyists in the community, and others with manufacturing experience and creative tendencies, we have identified even more niches and applications for this technology than we first envisioned. Many different people: doll makers, artists, model makers, action figure enthusiasts, can go from clay original to silicon mold to producing and selling limited edition reproductions. Candy makers can make custom and personalized hollow chocolate figures, even people making R2-D2 replicas with hollow parts that have been cost prohibitive to have machined. Custom bike builders can even rotational cast specialty/themed turn signal lenses.
The possibilities are endless! Rotational molding parts with the RotoMAAK can save you time and money, and is a bridge between one off part production and the cost of injection molding.

Rotational caster can be your printers best friend. I think we will se more of those machines in the future, and Rotomaak will be open sourced. Kudos for that! Sharing is caring!

They just had finished successful Kickstarter campaign with 211 backers that pledged $52,800 of $17,000 goal. Great work!

Topolabs developing non-layered 3d printing software

Current FDM 3d printers print in layers which comes with certain limitations and aesthetics.  Topolabs is developing software that will enable 3d printing freed from constrains of layered printhead paths. Filament will travel in more organic shapes in all 3 dimensions. It will also enable more curved graphical and decorative surface elements printed directly on the object.

TopoLabs initial software suite will include:

  • Strength Designer: By printing 3D paths instead of flat layers, you can easily orient the "grain" to your part's inherent shape. Woodworkers have aligned the grain to the task for thousands of years. Now your printer can too. 
  • Flexible Part Designer: Easily create flexible, fabric-like structures. Many products that would typically be made of thick canvas, nylon fabric or leather can now be 3D printed directly in engineering polymers. With some of the new elastomer and advanced material filaments available the possibilities are endless. 
  • Aesthetics & Line Art: start with any sketch or photo and your printer can create beautiful line art on 2D and 3D surfaces of parts. Think of it like embroidery or 3D graphics you can apply to many types of surfaces. 
  • Layer Locking for even more strength: When you do need flat layers, lock them together. Topolabs layer locking tools interconnect adjacent layers using transverse rays to eliminate cleavage planes so your parts won't split. Finally really useful parts in all three directions.

Here is an example of different technology how more organic fractal algorithms can decrease wight and increase the strength of 3d printed object:

DIY 3d printed external power supply adapter as replacement for digital camera battery

I hate proprietary batteries, non-user replaceable batteries and non-standard power supplies. Companies just change battery design on each model and sell expensive external power accessories. It is a sort of planed obsolescence and a bad business practice.

Alex wanted to use his camera for timelapse photography but the battery couldn't last for two hours. Commercial power adapter was 30 euros so he designed and printed his own external power adapter that replaces the original battery. He published the design on Thingiverse. Problem solved for everyone with
Canon Powershot SX200.

This approach could also be used to print battery adapters that use batteries of different formats. Some batteries and power supplies for older models are impossible to find and projects like this could bring some old hardware back to life or give more features to existing machines.

DIY post extrusion 3d model painting system by Kikai Labs

Kikai labs developed low cost system for painting 3d printed objects after extrusion with help of custom extruder with attached simple colored markers. It prints a layer and then paints it with the marker befor doing the next layer.

After development process they made following conclusions:
  • Multi-material printing capability is retained (PLA, ABS, PVA, Filaflex, HIPS, etc.)
  • Can print using more than 3 colors with markers, but it’s cumbersome.
  • Software: we have a colored-object slicer that works with Slic3r, yet runs external to it. 
  • Pre-extrusion approach seems limited in detail achievable and in number of colors it can apply. 
  • Purging plastic or ink quickly is a problem.
  • Painting arches, floor, overhangs: possible to do using transparent filament.

Germans have developed more "germanic" solution to this problem with carbon build plate, which looks like more durable but it doesn't come in such variety of sizes:

3D print surface made from carbon by GermanRepRap

Getting stuff to stick on the printbed is sometimes like voodoo magic. And it doesn't always work.
You can count on Germans to solve this problem: GermanRepRap developed carbon printbed.
It is attached it to the heat bed with provided clamps and after printing and removing the object you can attache it right back and continue printing. No more glue, juice, tape or bubbles.

It's made from carbon and you can use it and re-use it until it's mechanically broken. Carbon is THE future kids!

There are no videos or independent reviews / tests, but hopefully there will be some in the future.

The price for a 460 x 400 x 0,8 mm size plate is 99.95 EUR and 29.95 EUR for the 230 x 230 x 0,8 mm version.
Plates are made to fit x400 / Protos series of 3d printers, I wish they made them in 200 X 200 mm version also.

Product description on company page (in German):

Carbon sheets can be found on ebay with varying prices and specifications and they can be cut with simple power tools. I wander if they could be used as DIY carbon print bed ... I don't see any special technology in this ... maybe I'm wrong. Does anyone have any experiance with this?

DIY 3d printed 50 $ prosthetic hand vs. high end 42000 $ prosthesis

Can you guess which is better?

From source article:

I recently had the opportunity to work with a great guy named Jose Delgado, Jr., a 53-year old who was born without most of his left hand. I made a 3D printed prosthetic hand for Jose and, after using it for a while, I asked him to give me some honest feedback about how it compares to his more expensive myoelectric prosthesis. This is obviously not an "apples to apples" comparison in terms of the devices, but the real value of a prosthesis comes from how useful it is on a day-to-day basis, and that is the focus of the comparison here.
This 3D printed prosthesis is a completely mechanical design. There are a series of non-flexible cords running along the underside of each finger, connecting to a "tensioning block" on the top rear of the device (the "gauntlet"). The tension is caused by bending the wrist downward. With the wrist in its natural resting position, the fingers are extended, with a natural inward curve. When the wrist is bent 20-30 degrees downward, the non-flexible cords are pulled, causing the fingers and thumb to bend inwards. A second series of flexible cords run along the tops of the fingers, causing the fingers to return automatically when tension is released.

3D printers are coming down in price rapidly. As of today, you can get a self-assembly kit starting at around a few hundred dollars, and a fully assembled "prosumer" level printer is going for around $1000-$2000. In other words, this kind of technology is becoming very accessible, and it's opening up some very exciting possibilities!

New videos of 3d printed houses from China

Two new videos emerged of ten 3d printed houses from China showing the process in more detail and company behind it. It looks like China really leads the way in this filed now. Their technology prints house modules off-site and then connects in the open. They also stick to traditional house shapes. Roofs are not printed due to technology limitations.
One other important aspect is that they use construction waste as material, which could also lower the prices and help to preserve the environment which is getting very badly damaged in China.

They were developed by the Suzhou Yingchuang Science and Trade Development Co., Ltd. in east China's Jiangsu Province and are currently used as offices.

New 3D System ProJet 1200 prosumer 3d printer aimed at hobbyists

This is big step forward in availability of this technology to home and prosumer users. 3D Systems is entering strong into this market with this product. It is priced at 4900 USD.
This may mark a milestone in moving away from FFF printers for big companies in the field.

As you may notice, this SLA machine has a very small print volume, and it probably originated in dental / jewelry targeted printers. However, as 3D Systems, as a major player moves in this DIY segment with this technology, other big companies (such as Makerbot) will have to follow. There are definitely better SLA machines in the market for home segment, but from smaller companies. FFF 3d printers market is very saturated so DIY home SLA printers could be the next step for the entire industry.

3D Systems already entered this market segment with Projet 1000 / 1500 series, but those machines are bulky and priced over 10000 USD.

One good thing about this is tha we will probably see much cheaper and better high end SLA machines aimed ad DIY users.

Here is the Projet 1200 PDF brochure:

Lix - the smallest 3d drawing pen

Lix is the new 3d drawing pen with elegant aluminum body with small size. It is almost the same size as simple ball pen. It can be powered by USB port and you can carry it with you everywhere. Both ABS and PLA fulament can be used to create 3d drawings.

The pen will be launched on Kickstarter for $139.95 USD soon.

Lix vs 3Doodler (or any other 3d drawing pen currently available)

Lix 3d drawing pen technical specifications

Update (1.5.2014.):

Lix is no on Kickstarter and it is raising a LOT of money:

Update 2 (3.5.2014.):

There is an article on hackaday about can Lix actually work because USB does not provide enough power:

Update 3 (23.5.2014.):

Surprise, surprise: Lix is in problems:
LIX appears to have entered into the start of their Kickstarter campaign with an idea, and a very basic prototype. Their business plan seems to be changing and evolving based on two main factors. One is feedback from their backers, and the other is the huge demand that they have unexpectedly received for their future product.
LIX has announced that they are going to be hiring an engineering company to work on the newest prototype of the pen. The engineering firm that is being assigned to this project, will need more time in order to create a high quality product. They expect to have to redesign some of the aspects of the LIX Pen, to prepare it for mass-production.
They also changed their shipment schedule and postponed the dates ... good luck to the backers ...


Voxel 3d printed mobility assistance cane for the visually impaired

Another great example of using 3d printing for prototyping and developing new technologies for the disabled. I couldn't find more information on it except video description. It would be great if the creators would open source it.

From video description:
A smart white cane that helps the visually impaired keep active and independent.
Voxel gives anyone mobility assistance by integrating a traditional white cane, with new technologies.

An estimated 285 million people worldwide are visually impaired, with 39 million of those blind and 246 having low vision. The smart white cane, combines GPS technology and long distance measuring sensors, allowing the blind or visually impaired person to navigate public spaces with ease.
The user's smart phone's GPS, provides directional guidance. Turn by turn vibrational feedback is received through the handle, which allows the user to pocket their smart phone and have a hand free.
Feedback on obstacles is provided through LED lights located at the base of the cane. This helps those with low vision or other vision impairments such as macular degeneration, to become more aware of their surroundings and getting used to using a cane.
Using 3D printing, and the open source digital community, repairs are minimised and personalisation of the cane is only a limit of the current 3D printing materials.
The user is able to navigate the smart phone application through the use of accessibility, allowing them to order new or replacement parts.
Voxel gives anyone who is visually impaired the option to use an electronic mobility aid.

Here are two projects that can also hep visually impaired and blind:

China leads the way (maybe) in low cost 3d printed houses

This story is interesting and somewhat strange. Over at they published an article about 10 3d printed houses that were made in one day in China.
Since it was published on April 1st some people thought it was a joke. There are photographs but third-party references are missing.
It is still feasible that it is real story since China leads the way in many technologies (in they own way) ...

From the source article:

A group of 3D printed houses, 200 m2 each, recently appears in Shanghai, China. These building were created entirely out of concrete using a gigantic 3D printer, and each costs only 30,000 RMB ($4,800).

The company behind these 3D printed building, Shanghai WinSun Decoration Design Engineering Co, said it has for years been working on developing the system and its materials. The company owns 77 national patents of construction materials, such as glass fiber reinforced gypsum and special glass fiber reinforced cement.

While Hobbyist models of 3D printers are currently available for only a few hundred dollars and lets users feed plastics and polymers into a machine, the company takes this technology to a bigger level. Using concrete, instead of plastic, WinSun wants to revolutionize the way homes and other structures are built.
WinSun's 150(L) x 10(W) x 6.6(H) m gigantic 3D printer is capable of printing entire building within hours. The 'ink' it used is based on high-grade cement and glass fiber. Like traditional 3D printers, the system carefully spills out those materials layer by layer, consistently building upwar
In addition, it is very impressive that the printing material is recycled construction waste, industrial waste and tailings.
WinSun plans to build 100 recycling factories in the country, one in every 300km, to collect and transform the waste into materials for 3D printing through special handling, processing and separation technology. "There will not be any waste from the construction of new buildings." said WinSun CEO Ma YiHe. WinSun expects 3D printing will save construction companies up to 50% on the cost.

Here are some new videos with more details:

Fully 3d printed foldable shell tiny house by Peter Ebner

Peter Ebner and fully 3d printed Small Transportable Living house

From the article source:

Peter Ebner and his workshop students from the University of California in Los Angeles, University of British town of Huddersfield, Munich Technical University and the Center for Entrepreneurship and University of Applied Sciences have developed a project of the Small Transportable Living and had already built its pilot version.
This house of about 50 ft2 is a variation of a mobile mini-house. Authors of the project explain the relevance of such houses by the fact that now a half of young citizens aged 20-35 lives alone and spends not so much time at home (such dramatic changes in the habits of the population occurred in the last two decades), and, therefore, does not need a spacious housing. Moreover, housing becomes a scarce and costly commodity due to the constant influx of new residents in the city.
But, unlike such mini-houses as “Diogenes” by Renzo Piano, Small Transportable Living in addition to the minimum necessary functions (bedroom, kitchen, bathroom) offers an integrated multimedia system: the projection screen takes up most of the wall and serves as the semantic center of the house. The screen is visible best from the bed on the mezzanine floor, where the projector is hidden.
Streamlined shapes of the house with “dome” shape of the overlap allowed to easily integrate most of the furniture. Also the designers have widely used space under the floor. In addition to technical areas, there are two compartments for storing folding chairs. The main source of light and fresh air is an Oculus window over the bed. A house owner can get on the bed using ladder.
In order to save space, a movable kitchen countertop with sink covers a bathtub. A small kitchen table can be extended out of this surface. The table is comfortable enough for two people. There is also a small fridge. Bathroom is equipped with a “folding” toilet, which can be hidden in the wall. In addition to the bathtub, the house has a shower and a sink.
However, the main feature of the house is its production that requires a 3D-printer. Every small detail, such as “spring” mattress was printed on 3D printer. The designers have printed not only the support structure of the house, but also electricity, heating, water, sewage systems, and thermal insulation.
