Nanoscribe: Micro 3D Printer May Enable Industrial Breakthrough
Micro 3D printer Nanoscribe is revolutionizing 3D printing on a tiny scale.
Today’s 3D printers can do amazing things, but take a long time to actually create an object – a few hours for an iPhone case and 2,500 hours for a full car. A new desktop 3D printer called Nanoscribe can create complex microstructures incredibly fast – seconds instead of minutes and minutes instead of hours.
Michael Thiel, chief scientific officer at Nanoscribe (a spin-off from the Karlsruhe Institute of Technology in Germany) recently spoke with MIT Technology Review about his company’s new 3D printing technology and the potential impact on producing medical and electronic devices.
Printing microstructures with features a few hundred nanometers in size could be useful for making heart stents, microneedles for painless shots, gecko adhesives, parts for microfluidics chips, and scaffolds for growing cells and tissue. Another important application could be in the electronics industry, where patterning nanoscale features on chips currently involves slow, expensive techniques. 3D printing would quickly and cheaply yield polymer templates that could be used to make metallic structures.
So far, 3D microprinting has been used only in research laboratories because it’s pretty slow. In fact, many research labs around the world use Nanoscribe’s first-generation printer. The new, faster machine will also find commercial use. Thiel says numerous medical, life sciences, and nanotechnology companies are interested in the new machine. “I’m positive that with the faster throughput we get with this new tool, it might have an industrial breakthrough very soon,” he says.
The technology behind most 3D microprinters is called two-photon polymerization. It involves focusing tiny, ultrashort pulses from a near-infrared laser on a light-sensitive material. The material polymerizes and solidifies at the focused spots. As the laser beam moves in three dimensions, it creates a 3D object.
Today’s printers, including Nanoscribe’s present system, keep the laser beam fixed and move the light-sensitive material along three axes using mechanical stages, which slows down printing. To speed up the process, Nanoscribe’s new tool uses a tiny moving mirror to reflect the laser beam at different angles. Thiel says generating multiple light beams with a microlens array could make the process even faster.
Nanoscribe plans to start selling 3D printers later this year.

The Objet1000 is Objet‘s largest ever 3D printer. With a build platform of 1000 x 800 x 500 mm (39 x 31 x 20 inch), the system enables designers, engineers and manufacturers to quickly and easily create large and very precise models for prototyping parts and products in automotive, defense, aerospace, consumer goods, household appliances and industrial machinery sectors. The system features Objet Connex multi-material technology offering standard and ABS plastic performance, a choice of over 100 materials and the ability to mix up to 14 different materials in a single prototype or model to achieve the true look, feel and function of your intended end product.
Object Scholar Package Brings 3D Printing to Students and Universities
3D printer manufacturer Objet Ltd. has announced the release of an accessible, attractively-priced and all-inclusive 3D printing package for schools, colleges, universities and institutes of higher education, called the Objet30 Scholar Package.
Here is the full press release:
“The Objet30 Scholar Package was developed to make Objet’s 3D printing systems and solutions even more accessible to the strategically important education market,” says Gilad Gans, Executive Vice President for Objet. “It provides students and faculties across multiple disciplines – particularly STEM curriculum studies – with increased opportunities to create and prototype advanced design ideas.”
Tailor-made 3D printing solutions for the education market are a strategic objective of Objet. The company’s 3D Printers have been adopted by many of the world’s leading universities and research departments, including Virginia Tech, University of New Orleans, Art Center College of Design, Purdue University, and The Technion.
The package was designed with educators in mind allowing academic institutions to focus on creativity. It includes the Objet30 Scholar professional desktop 3D Printer; two or three year supply of rigid opaque 3D printing materials (Objet RGD240 rigid blue and support material) which Objet will store and deliver on-demand; a desktop Water-Jet system to remove the support material; training for users; maintenance of the 3D Printer; and technical support. Objet30 Scholar customers are also entitled to further discounted 3D printing material re-fill packages.
The Objet30 Scholar provides 28 micron layer accuracy and the material features high-detail visualization for simulating the precise look of standard plastic products. As well as giving students the ability to develop a 3D printing project portfolio, the Objet30 Scholar package provides graduates and post-graduates with valuable knowledge and experience that can help support future design and manufacturing careers in Fortune 500 companies that operate similar professional 3D printing systems.

Open-Source 3D Printer Pwdr Takes on MakerBot, Offers New Materials
There’s a new open-source 3D printer in town, and its name is Pwdr.
In a change from the technique used by MakerBot 3D printers of extruding plastic onto a platform layer by layer, Pwdr operates like the expensive industrial powder printers. This opens new doors for the consumer 3D printing market.
A whole new range of materials become available for experimenting with open-source rapid-prototyping; for example, when using the 3DP process: gypsum, ceramics, concrete, sugar, etc. And when the SLS process is fully supported, plastic materials like ABS, PP, Nylon and metals become available as building material.A Hewlett Packard inkjet cartridge is used for the deposition of binder. The cartridge can be refilled with custom binders using a syringe. A custom binder of 20% alcohol and 80% water has been proven to work.
The Pwdr Model 0.1 consists of chassis, tool head and electronics. The printer entirely consists of off-the-shelf components. It has a simple design and can be built within a couple of hours. The machine is easy and affordable to build and modify. Building a Pwdr Model 0.1 machine costs about €1000.
3D Printing On the Go: Portable 3D Printer PopFab Fits in a Suitcase
Every consumer electronic technology starts out large and eventually becomes portable. Computers were once mainframes the size of a large room and now can fit in the palm of your hand. The same trend is being followed for 3D printers.
Two MIT students have designed PopFab: a 3D printer that fits in a suitcase and can be a carry-on piece of luggage.
Described as a multi-tool, perhaps the Swiss Army knife of 3D printers, the video below shows the two students setting up PopFab bit by bit, and is part of a series that will show off the mobile 3D printer’s capabilities.
In just a few moments, the students assembled the printer through attaching the printing head to a fold-out arm. Next, they placed the printing material and connected a computer which is used to relay the design to the machine.
In the video, the printer is used to create a small, three dimensional fish. However, the portable design could potentially be used to perform different functions — change the toolhead, switch the service. For example, the team believe it could also be used to cut vinyl, perform milling or draw programmed designs.
