Suspended deposition 3d printing technology

Robotic hand injecting light curing material in gel block. It has "undo" option and can utilize 3D vector-based toolpaths.

Suspended Depositions from BrianHarms on Vimeo.
This project aims to blur the line between processes of design and fabrication in the context of rapid prototyping by increasing the fluidity of the fabrication process through coordinated material and robotic processes. The project exploits feedback loops that allow the process to be used as a live generative form-finding tool as well as a method for reification of designed objects.

By injecting and suspending light-curing resin in a gelatinous medium, one is afforded the ability to shape freeform objects without the need for molds or other subtractive manufacturing processes that would otherwise be necessary. The gel acts as an omnidirectional support material which is reusable, so there is no wasted material.

One major distinction between this project and other rapid prototyping processes is the ability to utilize 3D vector-based toolpaths. Virtually all other processes use paths generated via contouring a digital model, and rely on the hardening of each successive layer before being able to move on to the next.

The suspension of resin in space without added support material allows for the ability to navigate and fabricate directly on and around other existing objects within the Gel, as well as the ability to observe the process from any angle. The suspension of time in this process allows for tool changes, manual injections, on-the-fly robotic injections, multi-material injections, live modification of the digital or physical model, and the ability to physically "undo" (resin removal via suction or scooping).

Disney researches 3d printed mechanical characters

Soon in toy store near you ...

From project site:
We developed an interactive design system that allows non-expert users to create animated mechanical characters. Given an articulated character as input, the user iteratively creates an animation by sketching motion curves indicating how different parts of the character should move. For each motion curve, our framework creates an optimized mechanism that reproduces it as closely as possible. The resulting mechanisms are attached to the character and then connected to each other using gear trains, which are created in a semi-automated fashion. The mechanical assemblies generated with our system can be driven with a single input driver, such as a hand-operated crank or an electric motor, and they can be fabricated using rapid prototyping devices.
We demonstrate the versatility of our approach by designing a wide range of mechanical characters, several of which we manufactured using 3D printing. While our pipeline is designed for characters driven by planar mechanisms, significant parts of it extend directly to non-planar mechanisms, allowing us to create characters with compelling 3D motions.

3d printed couples rings

Awwwwwww ... this is sooo sweeet ... or: How to make plastic cherishable.

MY Reason Your Ring from Christopher Scott on Vimeo.
My Reason Your Ring is a celebration and reflection of why couples are together. Using contemporary 3D printing technologies, an accessible and democratic material, My Reason Your Ring evolves what is cherishable about the objects from monetary to relational as only one partner has the ability to print the ring for the other through the reason for their relationship that they choose as a password. Because of the nature of the material, the rings can be truly lived in; lost on a picnic, scratched, faded in the sun, dropped in the ocean, etc., only to be replaced by one’s partner. The rings are designed as inverses where the volume on one becomes the void on the other, becoming unique symbols for the couple.

VIA (Visual Impairment Aid)

Wow! What an amazing project! Kudos Mr. Mizchief100!

From project page:

This project was my take on a DIY visual impairment aid that uses haptic and sound feedback. Basically it uses a distance sensor to measure how far objects are from it and then it beeps/vibrates accordingly (far away is slow vibrate/long beep delay and close up is fast vibrate/quick beeps). The difference between this project and others is this project uses one distance sensor (as opposed to many) to make feedback more specific and simpler to interpret, use of both haptic and sound feedback, the mounting of the device under the arm and not attached to the hand (keeps it free to feel where you're going and use for daily tasks), and a few simple control buttons on the case (I also put the word for each button in braille next to them). What I really like about the design is how compact and sturdy it is. I wore it around for a few hours to get used to it and found it didn't hinder too many of my daily activities (I found it fit in sleeves too!).

Make It Stand - balancing 3d models

Software that makes your models stand. It adjusts shape - pose - weight balance without the need for heavy bases or magnets. There is no download of the software I can find, hopefully it will show up somewhere. The paper explaining science and calculations behind it is available so maybe it can be interdependently programmed.

Research abstract:

Imbalance suggests a feeling of dynamism and movement in static objects. It is therefore not surprising that many 3D models stand in impossibly balanced configurations. As long as the models remain in a computer this is of no consequence: the laws of physics do not apply. However, fabrication through 3D printing breaks the illusion: printed models topple instead of standing as initially intended. We propose to assist users in producing novel, properly balanced designs by interactively deforming an existing model. We formulate balance optimization as an energy minimization, improving stability by modifying the volume of the object, while preserving its surface details. This takes place during interactive editing: the user cooperates with our optimizer towards the end result. We demonstrate our method on a variety of models. With our technique, users can produce fabricated objects that stand in one or more surprising poses without requiring glue or heavy pedestals.

3D Printers Shown To Emit Potentially Harmful Nanosized Particles

Let the fear-mongering begin!

An anonymous slashdot reader writes:
"A new study by researchers in the Built Environment Research Group at the Illinois Institute of Technology shows that commercially available desktop 3D printers can have substantial emissions of potentially harmful nanosized particles in indoor air. Many desktop 3D printers rely on a process where a thermoplastic feedstock is heated, extruded through a small nozzle, and deposited onto a surface to build 3D objects. Similar processes have been shown to have significant aerosol emissions in other studies using a range of plastic feedstocks, but mostly in industrial environments.
In this study, researchers measured ultrafine particle concentrations resulting from a popular commercially available desktop 3D printer using two different plastic feedstocks inside an office. Ultrafine particles (or UFPs) are small, nanosized particles less than 100 nanometers in diameter. Inhalation of UFPs may be important from a health perspective because they deposit efficiently in the lung and can even translocate to the brain. Estimates of emission rates of total UFPs in this study were high, ranging from about 20 billion particles per minute for a 3D printer utilizing a lower temperature polylactic acid (PLA) feedstock to about 200 billion particles per minute for the same type of 3D printer utilizing a higher temperature acrylonitrile butadiene styrene (ABS) feedstock.
The emission rates were similar to those measured in previous studies of several other devices and indoor activities, including cooking on a gas or electric stove, burning scented candles, operating laser printers, or even burning a cigarette."

Abstract of the research (

The development of low-cost desktop versions of three-dimensional (3D) printers has made these devices widely accessible for rapid prototyping and small-scale manufacturing in home and office settings. Many desktop 3D printers rely on heated thermoplastic extrusion and deposition, which is a process that has been shown to have significant aerosol emissions in industrial environments. However, we are not aware of any data on particle emissions from commercially available desktop 3D printers. Therefore, we report on measurements of size-resolved and total ultrafine particle (UFP) concentrations resulting from the operation of two types of commercially available desktop 3D printers inside a commercial office space. We also estimate size-resolved (11.5 nm to 116 nm) and total UFP (< 100 nm) emission rates and compare them to emission rates from other desktop devices and indoor activities known to emit fine and ultrafine particles. Estimates of emission rates of total UFPs were large, ranging from ∼2.0×1010 #/minute for a 3D printer utilizing a polylactic acid (PLA) feedstock to ∼1.9×1011 #/min for the same type of 3D printer utilizing a higher temperature acrylonitrile butadiene styrene (ABS) thermoplastic feedstock. Because most of these devices are currently sold as standalone devices without any exhaust ventilation or filtration accessories, results herein suggest caution should be used when operating in inadequately ventilated or unfiltered indoor environments. Additionally, these results suggest that more controlled experiments should be conducted to more fundamentally evaluate particle emissions from a wider arrange of desktop 3D printers.


In this work, we present some of the first known measurements of which we are aware of UFP emissions from commercially available desktop 3D printers. Emission rates of total UFPs were approximately an order of magnitude higher for 3D printers utilizing an ABS thermoplastic feedstock relative to a PLA feedstock: ∼1.9×1011 #/min compared to ∼2.0×1010 #/min. However, both can be characterized as “high emitters” of total UFPs. These results suggests caution should be used when operating some commercially available 3D printers in unvented or inadequately filtered indoor environments. Additionally, more controlled experiments should be conducted to more fundamentally evaluate aerosol emissions from a wider arrange of desktop 3D printers and feedstocks.

So, I think ventilation, fumes separation and/or extraction, insulated print chambers are the next things in 3d printers.


Looks like someone already had a similar idea, DIY fume cabinet for fumes extraction:

3D printing with silkworms

Something completely different ...

From video description:

The Silk Pavilion explores the relationship between digital and biological fabrication on product and architectural scales.
The primary structure was created of 26 polygonal panels made of silk threads laid down by a CNC (Computer-Numerically Controlled) machine. Inspired by the silkworm's ability to generate a 3D cocoon out of a single multi-property silk thread (1km in length), the overall geometry of the pavilion was created using an algorithm that assigns a single continuous thread across patches providing various degrees of density.
Overall density variation was informed by the silkworm itself deployed as a biological "printer" in the creation of a secondary structure. A swarm of 6,500 silkworms was positioned at the bottom rim of the scaffold spinning flat non-woven silk patches as they locally reinforced the gaps across CNC-deposited silk fibers. Following their pupation stage the silkworms were removed. Resulting moths can produce 1.5 million eggs with the potential of constructing up to 250 additional pavilions.
Affected by spatial and environmental conditions including geometrical density as well as variation in natural light and heat, the silkworms were found to migrate to darker and denser areas. Desired light effects informed variations in material organization across the surface area of the structure. A season-specific sun path diagram mapping solar trajectories in space dictated the location, size and density of apertures within the structure in order to lock-in rays of natural light entering the pavilion from South and East elevations. The central oculus is located against the East elevation and may be used as a sun-clock.
Parallel basic research explored the use of silkworms as entities that can "compute" material organization based on external performance criteria. Specifically, we explored the formation of non-woven fiber structures generated by the silkworms as a computational schema for determining shape and material optimization of fiber-based surface structures.
Research and Design by the Mediated Matter Research Group at the MIT Media Lab in collaboration with Prof. Fiorenzo Omenetto (TUFTS University) and Dr. James Weaver (WYSS Institute, Harvard University).

Focus DIY powder 3d printer

Powder SLS DIY 3d printers are still in infancy. Focus project is trying to advance the area, but it is in early development stages with limited functionality.

Test print with nylon powder and carbon mixture

From project page:

Focus is a 3D printer that is designed to print using Selective Laser Sintering. Focus can also be adapted for FDM, 3DP and lasercutting/engraving.
Right now, Focus is a work in progress. I have been working on it since october last year. Since then a full design has been made. The printer and electronics have been built and a complete pack of firmware has been written. The firmware has been built from scratch because SLS and FDM just differ too much. The firmware handles normal FDM Gcode, and uses the E axis to determine if the laser has to be turned on or off.

Focus prints using a focusable 1500mw 808nm laser that sits on 2 axis. Both pistons move with a 64 step 1:64 geared stepper motor. The Gcode is stored on a SD card. The printer is stand alone and is controlled with a 4x20 LCD screen and 8 buttons. The printer is built using 3D printed parts and MDF.

The printer can be built for less than €600 (, or about $800), if you source the parts right.
(Edit, A rough parts list with prices for the printer have been added to the downloads)

Right now I only have engraved with the printer, but every system is about ready to start actual printing. I will post videos and pictures of this as soon as I have the process under control.

Spray for 3d printing: 3D LAC

At first I was thinking it was some sort of a joke. Then I realized that it makes some sense. Spray custom made for 3d printing: no perfume and more adhesion. Idea is to spray it on build platform and make objects stick to it better, which was sometimes done by applying regular commercial hair spray.

Web page seems to be under development without much information, but we will see will this product gain some traction or it is just vaporware (pun intended).

NASA successfully tests 3d printed rocket engine injector


NASA and Aerojet Rocketdyne recently finished testing a rocket engine injector made through additive manufacturing, or 3-D printing.
This space technology demonstration may lead to more efficient manufacturing of rocket engines, saving American companies time and money. The tests were conducted at NASA's Glenn Research Center in Cleveland.
The series of tests demonstrated the ability to design, manufacture and test a critical rocket engine component using selective laser melting manufacturing technology -- a method that employs high-powered laser beams to melt and fuse fine metallic powders into three dimensional structures.
"NASA recognizes that on Earth and potentially in space, additive manufacturing can be game-changing for new mission opportunities, significantly reducing production time and cost by 'printing' tools, engine parts or even entire spacecraft," said Michael Gazarik, NASA's associate administrator for space technology in Washington. "3-D manufacturing offers opportunities to optimize the fit, form and delivery systems of materials that will enable our space missions while directly benefiting American businesses here on Earth."
This type of injector manufactured with traditional processes would take more than a year to make, but with these new processes it can be produced in less than four months, with a 70 percent reduction in cost.
The project is supported by the Game Changing Technology Program in NASA's Space Technology Mission Directorate, which is innovating, developing, testing and flying hardware for use in NASA's future missions.

Ultrasonic metal 3d printing

I just discovered this process ...

From video description:

The patented Ultrasonic Additive Manufacturing (UAM) process uses the power of sound to merge layers of metal foil. The process produces true metallurgical bonds with full density and works with a variety of metals such as aluminum, copper, stainless steel, and titanium. In combining additive and subtractive process capabilities, UAM can create deep slots, hollow, latticed, or honeycombed internal structures, and other complex geometries impossible with conventional subtractive manufacturing processes. Additionally, the solid state nature of the UAM bond allows for welding of dissimilar metals. This enables dissimilar metal cladding, production of custom metal matrix composites, and the ability to embed objects or sensors in a metal substrate. Through the use of UAM technology, customers will be able to manufacture complex parts that have unique features and attributes not possible using traditional manufacturing techniques. In addition, parts currently made with traditional operations can be made with much less waste, an increasingly important factor as more expensive, higher performance materials see broader use.

DIY 3D printed Swiss army knife scales

I found some interesting projects on Instructables. This one is about 3d printing custom scales for your Swiss army knife. You can make your DIY replacement scales for a standard SAK with some additional functionality. It's a sort of repair / upgrade swiss army knife hack.

Link with instructions and files:

Here is a different take on DIY 3d printed SAK scales for a smaller keychain model which look much better and probably gives a better grip:

3D printed fashion show shoes

OK, I'm going to say it: those are some VERY UGLY shoes. It's probably on everyone's mind. But they are 3d printed.

Ford Freeform Fabrication Technology (F3T), 3d printing with sheets of metal

Ford developed new prototyping technology. It makes 3d prototypes from sheets of metal using robotic hands. Looks cool and it will probably be standard full production technology one day.

Two pressure heads moved via robotic hands shape the model from two sides.

The technology is not new, probably only the implementation and new machinery is developed.
