3d printing materials, education, google, scienceAdaptive 3D Technologies makes the toughest - and softest - 3D printed polymers on the market by creating custom materials specifically designed to be 3D printed. Advanced processing techniques eliminate anisotropy and result in durable, high quality parts that can be used directly in practical applications far beyond current stereotypes of 3D printing (prototyping). Walter Voit is the president of Adaptive 3D Technologies and an Assistant Professor in Materials Science and Engineering and Mechanical Engineering at The University of Texas at Dallas.

03.45.00Unknownheated build platform, print bed
Like many, I'm fed up with the common MK2B heated bed. It has about 1.2 Ω when wired in 12 V configuration and 4.8 when wired in 24 V configuration. Both times it outputs about 120 W of heat when driven by the appropriate voltage, resulting heatup times to print temperature of 10 to 20 minutes.
Heatup time can be reduced to 2 minutes by simply driving it with 24 V while wiring it in 12 V configuration, but well, this almost max out a seperate 500 W 24 V power supply I dedicated to driving the heated bed. Additional requirements for this setup are at least AWG 15 wire and a high current MOSFET or SSR.
The additional cost of a 500W 24 V power supply, high current SSR and heavy wire is not neglectable at all, since the can easily be half of a printers price tag. Also, bulky power supplys and wires do not contribute to the overall design and weight aspects of a 3D printer.
There are many benefits of a mains voltage heated bed: I will be driven directly from mains, skips the need for an expensive power supply and can be driven by a cheap low current SSR without heatsink. It's also cheap and provides a structural support for your printing plate, be it glass, tufnol/garolite or PEI - which silicone heater pads do not do.
Thus, a mains voltage heated bed must exist, and this project is dedicated to make it real. Additionally, this is also an attempt in making this the safest heated bed available. If you have concerns with the design, please share your ideas in the comments.

Personal fabrication is currently a one-way process: Once an object has been fabricated with a 3D printer, it cannot be changed anymore; any change requires printing a new version from scratch. In this paper, we propose a different approach: instead of re-printing the entire object from scratch, we suggest patching the existing object and replacing only the unsatisfactory parts. This saves material and reduces waste, making a first step towards more sustainable 3D printing.
This project is a collaboration between Hasso Plattner Institute and Cornell University.

13.49.00Unknownlaser cutting, plastic weldingLaserStacker uses the laser cutter to not only cut but also to weld. Users place not one acrylic sheet, but a stack of acrylic sheets into their cutter. In a single process, LaserStacker cuts each individual layer to shape (through all layers above it), welds layers by melting material at their interface, and heals undesired cuts in higher layers. When users take out the object from the laser cutter, it is already assembled.
This is a project from the Human-Computer Interaction Lab at Hasso Plattner Institute.

Apple’s patent application covers a method for 3D printing investment molds to be filled with molten amorphous alloy. These alloys are configured to form a bulk metallic glass (BMG) on cooling. BMGs, (also known as Bulk Amporhous Alloys) are a new class of metallic alloys that are extremely strong, with superior elastic strain limits and resistance under shock impact. They are therefore ideal for the manufacturing of electronic device housings and cases.Here is a patent page: LINK

By modifying a standard low-cost FDM printer with a revolving cuboidal platform and printing partitioned geometries around cuboidal facets, we achieve a multidirectional additive prototyping process to reduce the print and support material use. Our optimization framework considers various orientations and sizes for the cuboidal base.
The mechanical, electronic, and sensory components are preassembled on the flattened laser-cut facets and enclosed inside the cuboid when closed. We demonstrate RevoMaker directly printing a variety of customized and fully-functional product prototypes, such as computer mice and toys, thus illustrating the new affordances of 3D printing for functional product design.

Connex 500 printed 3d model of a portion of San Francisco. The model was created to aid real-estate developer Tishman Speyer in telling the story of urban development in the rapidly changing SOMA neighborhood. It can help with urban planning and building construction decisions that are better understood with the kind of physicality that only a real-world 3D replica offers compared to digital images or digital models.
07.27.00Unknown3d printed robot, design, disneyWe present an interactive design system that allows casual users to quickly create 3D-printable robotic creatures. Our approach automates the tedious parts of the design process while providing sample room for customization of morphology, proportions, gait and motion style.
The technical core of our framework is an efficient optimization-based solution that generates stable motions for legged robots of arbitrary designs. An intuitive set of editing tools allows the user to interactively explore the space of feasible designs and to study the relationship between morphological features and the resulting motions. Fabrication blueprints are generated automatically such that the robot designs can be manufactured using 3D-printing and off-the-shelf servo motors.
We demonstrate the effectiveness of our solution by designing six robotic creatures with a variety of morphological features: two, four or five legs, point or area feet, actuated spines and different proportions. We validate the feasibility of the designs generated with our system through physics simulations and physically-fabricated prototypes.

We present AutoConnect, an automatic method that creates customized, 3D-printable connectors attaching two physical objects together. Users simply position and orient virtual models of the two objects that they want to connect and indicate some auxiliary information such as weight and dimensions. Then, AutoConnect creates several alternative designs that users can choose from for 3D printing. The design of the connector is created by combining two holders, one for each object. We categorize the holders into two types. The first type holds standard objects such as pipes and planes. We utilize a database of parameterized mechanical holders and optimize the holder shape based on the grip strength and material consumption. The second type holds free-form objects. These are procedurally generated shell-gripper designs created based on geometric analysis of the object. We illustrate the use of our method by demonstrating many examples of connectors and practical use cases.Project homepage:

05.50.00Unknown3d printed buildings, house, robotRock Print is the first architectural installation to be built from low-grade granular material and constructed by robotic machines. Conceived as an intriguing vertical object, the installation presents a radically new approach to The State of the Art of Architecture – the official title of the inaugural Chicago Architecture Biennial 2015 – and brings forward a new category of random packed, potentially fully reusable, poly-dispersed jammed structures that can be automatically fabricated in non-standard shapes. Following an initial period of robotic assembly, the installation will comprise a large-scale architectural artefact in its completed form, exhibiting distinct features, such as, for example, full material reversibility and the respective reusability of the aggregated materials; structurally active interlocking, differentiated structural performance, while yielding high geometric flexibility and articulation. Performing a full scale 3D “rock printing process” that uses the self-aggregating capacities of the material itself, this visionary project is the first collaborative installation by Gramazio Kohler Research, ETH Zurich, and the Self-Assembly Lab, MIT. The Chicago Architecture Biennial will open on 3rd October 2015 and will close on 3rd January 2016. For more information: www.chicagoarchitecturebiennial.org

We have developed a multi-material 3D printing platform that is high-resolution, low-cost, and extensible. The key part of our platform is an integrated machine vision system. This system allows for self-calibration of printheads, 3D scanning, and a closed-feedback loop to enable print corrections. The integration of machine vision with 3D printing simplifies the overall platform design and enables new applications such as 3D printing over auxiliary parts.
Furthermore, our platform dramatically expands the range of parts that can be 3D printed by simultaneously supporting up to 10 different materials that can interact optically and mechanically. The platform achieves a resolution of at least 40 micrometers by utilizing piezoelectric inkjet printheads adapted for 3D printing. The hardware is low cost (less than $7,000) since it is built exclusively from off-the-shelf components.
The architecture is extensible and modular -- adding, removing, and exchanging printing modules can be done quickly. We provide a detailed analysis of the system's performance. We also demonstrate a variety of fabricated multi-material objects.
