Henri Canivez’s 3D Printed Data Stool Will Be Unique to You https://ift.tt/2Jm8IVH Designer Henri Cenivez‘s Data Stool has a unique size and shape depending on the person. One can sit on the data logging stool and this stool will measure and weigh the user. Depending on your weight and measurements a unique data stool will be 3D printed in the corresponding size. The stool measures both the height and weight of your lower body. What’s more, a unique design will be created with each stool being just a little bit different depending on your measurements. If you’re heavier it will add in denser structures or even change the design to support you. Canivez’s intent was to make data visible. Data surrounds us and powers so much of our lives. By making the capturing of data visible via and creating a unique stool, based upon that data he hopes to have a completely unique way of seeing how data surrounds and influences us. Canivez showcased his design at the Design Academy Graduation during Dutch Design Week. The final stool itself will be made in two versions. One is 3D printed on a Builder Extreme 3D printer in PLA. Another version of the Data Stool is made out of aluminum and glass filled nylon. To make the stool Henri worked together with Dutch 3D Printer company Builder and CNC Speedform. Many designers have over the years have experimented with an algorithm based design. There are many ways through which we can capture data and then turn this into unique objects. In this case, a unique stool could better serve a person or perhaps use only what was needed in terms of material. A user could also feel much closer to such a stool and find it much more special than one that was not made specifically for them. Essentially the data logging step itself seems very quick. Instead of using scanning and measurements through a scale one simply sits down on the stool to get a reading. If algorithm driven furniture is to be a real thing in the future then a simple and fast way to capture a design will be essential. A quick sit down to get a custom stool will be a fast way to at a retail or other location capture data. Innovation in data capture and storage will be a key way through which mass customization companies will compete with each other. Its all well and good having one 3D scan done but would you then want to do another? If one extensive measurement battery were done by a trusted company then most would leave it at that. For those perhaps less interested in customization a simple fun sit down while envisioning a new possession made just for you might just be the perfect method through which to capture new customers. In this sense, the data collection portion of the stool is a presales and marketing tool as well as something that is part of the path to making an individualized item.

Researchers Present New System for Handling Particles and Fumes Produced by 3D Printers https://ift.tt/2Jl2t4x One of the concerns presented by desktop 3D printing is the amount of potentially harmful particles that are produced by the process. In a paper entitled “An Intelligent Exhaust Gas Processing System for Desktop 3D Printer,” a group of researchers discuss how they developed a system to perform adsorption and catalysis for desktop 3D printers. The system consists of a digital universal particle concentration sensor, a microcontroller, and a DC motor. The particle concentration sensor detects whether the concentration of particulates in the 3D printer exceeds the lowest critical value harmful to the human body.
A temperature acquisition circuit module monitors in real time the internal temperature of the 3D printer. A display circuit module and a motor control circuit module are also included.
For the exhaust of the 3D printer, the adsorption equilibrium constant is small, so it must be cooled before adsorption. After heating the desorption concentrated exhaust gas to a certain temperature, it catalyzes carbon dioxide and water, and discharges after cooling. The exhaust gas treatment equipment includes an adsorption-desorption device and a catalytic burner. Adsorption pad 3 is filled with a shaped adsorbent, and gas passes through to the adsorption zone for adsorption purification. A small amount of hot air blows through the desorption zone, the volatile organic compounds (VOCs) are forcibly desorbed, and the adsorbent is regenerated. The desorption of the adsorbent is cooled with a small amount of low-temperature airflow to ensure the effect of adsorption of the adsorption zone.
Authors of the paper include Ligang Cai, Shunlei Li, Qiang Cheng, Zhifeng Liu, Wei Cui and Huirong Fu. Discuss this and other 3D printing topics at 3DPrintBoard.com or share your thoughts below.

Indian Institute of Technology Madras Develops 3D Printed Homes That Take Three Days to Build https://ift.tt/2RjL7rj As 3D printing just continues to gain traction around the world—contributing enormous benefits and innovation to a wide range of industries—India has been embracing the technology and making strides with many different applications. Now, faculty and alumni at the Indian Institute of Technology Madras have developed a new program for 3D printed construction technology and have fabricated their first building. Meant to act as a start-up for a ‘re-envisioned construction process,’ the academic team is currently developing a 3D printing process that will allow them to create 320-foot, one-story homes within three days each. They are working from a progressive prototype that has already been created at the Institute, offering a concept that allows them to use all the benefits of 3D printing to fulfill the demands for housing in India. Affordability is a huge factor, along with speed in production time, less need for construction labor, and less challenge in transporting more expensive, and dense, materials.
Along with this current startup, IIT Madras is working with other government divisions to encourage education about—and the use of—technologies like 3D printing.
The government realizes the need for innovation in construction processes as housing issues become further pressing:
Aside from prototypes, it is expected that Tvasta will produce the first 3D printed homes within a year. What do you think of this news? Let us know your thoughts!

3YOURMIND Demonstrating Updated Version of Additive Manufacturing Part Identifier System at formnext https://ift.tt/2Q1dJpd Last spring, EOS and 3YOURMIND worked together to develop the Additive Manufacturing Part Identifier (AMPI), a system that will scan a company’s existing parts inventory, and then identify which ones are suitable for 3D printing. This helps the company determine which parts could potentially be replaced by 3D printed versions, which in turn increases adoption of the technology. Identifying the components and parts that could be 3D printed is still a big challenge, which is why systems like AMPI are so helpful. formnext 2018 will begin in just a few weeks in Frankfurt, and Berlin-based 3YOURMIND, which provides software for additive manufacturing workflows, will be there to present a totally revised version of AMPI.
AMPI makes it possible for organizations to find 3D printing use cases in their existing inventory, which in turn helps save on time and money. The software will automatically check large part databases in order to detect which parts would be good for 3D printing, in addition to determining if it’s better for any given part to switch from traditional to additive manufacturing to fabricate it. AMPI’s analysis, based on metadata of components like material section, production requirements, CAD specs, and quality, utilizes both economic and technical aspects to figure out if a part is right for 3D printing. One of the latest features in the updated AMPI is Use Case Screening, which allows nearly every employee in a given company, whether they work in production, procurement, or design, to use a clearly structure, digitized process to check specific parts and components for what 3YOURMIND refers to as “their economic and technical AM-feasibility.”
The revised AMPI platform allows users to directly access the world of 3D printing by performing Use Case Screenings on possible 3D assemblies and parts with the touch of a button. AMPI can transfer relevant 3D models into 3YOURMIND’s other tools to enter an end-to-end AM workflow…making AM adoption automated and seamless. Moving past AMPI, 3YOURMIND’s complete suite of software tools makes it easy to optimize components, material selection and price calculation, along with facilitating print job placement in the production workflow, automated printability analysis, and comprehensive data analysis for optimizing 3D printing. All of these tools have been integrated into the newest version of the company’s Enterprise platform for industrial 3D printing. Visitors to formnext, which takes place at the Messe Frankfurt from November 13-16, can see live AMPI demonstrations at 3YOURMIND’s booth G70 in Hall 3.1 Discuss this story and other 3D printing topics at 3DPrintBoard.com or share your thoughts in the comments below.

https://ift.tt/2PrZvk0
Halifax e-NABLE Branch Recycling Plastic Weed Container Lids into 3D Printed Prosthetic Limbs https://ift.tt/2CGvsON Last year, Halifax resident Jacob Boudreau, who works for a logistics company, watched a TED Talk by heartwarming 3D printed prostheticsvolunteer organization e-NABLE, and was inspired to open his own non-profit e-NABLE chapter, called Kindness3D.
Things started off normally enough, with Kindness3D using regular PLA material to fabricate prosthetics, including a 3D printed hand and arm for Brazilian athlete Kelly De Oliveira Malaquias and a hand to a young girl in Costa Rica. But Boudreau’s work to provide 3D printed prosthetics is now dovetailing with another passion – recycling plastic waste from what he refers to as the “excessive cannabis packaging conundrum” of the NSLC (Nova Scotia Liquor Corporation), the province’s legal cannabis distributor.
Recently, Canada became the first major world economy to legalize recreational marijuana. But many customers in Nova Scotia are criticizing the NSLC for using excessive packaging for the product. Cannabis guidelines for Health Canada say that the packaging must be tamper-proof, child-resistant, and prevent contamination. While the white plastic containers that Canada’s pot comes in do meet these guidelines, some consumer say they are environmentally unfriendly and not able to be recycled. Boudreau says that all of the lids will eventually end up in landfills…so he’s taking action. Just like the Million Waves Project uses recycled ocean plastic to make 3D printed prosthetic limbs, Boudreau and Kindness3D want to use these plastic pot container lids to make 3D printed prosthetics for kids.
He first got the idea to recycle the plastic cannabis lids into plastic for 3D printed prosthetic limbs when customers asked him if he could help with the waste problem.
First, Kindness3D modified a paper shredder so it could be used to break down the plastic pot container lids, so the shredded plastic could be used in the organization’s 3D printer. Then, it began to ask other local businesses to collect the used lids. Now, Kindness3D asks Nova Scotians to bring the empty cannabis containers, lids and all, to Boudreau’s Dalhousie University Sexton Campusoperation, and various other drop-off points, for recycling and reprocessing into prosthetic limbs. Since beginning the cannabis lid recycling project, Boudreau is already working to complete a 3D printed prosthetic arm for a four-year-old girl in California. Additionally, he started a petitionin hopes of convincing the NSLC to collect and donate all of its used cannabis packaging to Kindness3D. But, according to NSLC spokesperson Beverley Ware, the corporation has not been contacted by Kindness3D yet…maybe it’s waiting to get a certain number of signatures first? Ware is also requesting that customers continue to follow the recycling programs already set up in their communities.
I hope this recycling initiative by Kindess3D doesn’t turn into some kind of legal battle. I understand that there are rules for a reason, and maybe the infrastructure doesn’t allow for this sort of program just yet. But the non-profit is trying to do a very noble thing in both recycling large amounts of wasteful plastic and providing 3D printed prosthetics to the people who need them most, so I hope that everything will work out in the end.

Photographer Uses 3D Printing to Create a Camera Lens Made From Ice https://ift.tt/2OaHjqm Photographers like to experiment with different types of equipment – old-fashioned cameras like pinhole cameras, for example, or 3D printed lenses. French photographer Mathieu Stern, however, may have done something no other photographer has done before – created a camera with a lens made of ice. Not just any ice, either, but ice from an iceberg in Iceland. Stern had to modify his Sony camera to hold the ice lens, and that involved creating a 3D printed lens body. He worked on the project for six months to get the right shape and focus distance before he headed off for Iceland.
He ended up at Diamond Beach, a fortuitously named location for Stern’s search for clarity. The beach is about 200 miles east of Reykjavik, the capital of Iceland, and it was there that Stern found his perfect iceberg. Using an ice ball maker, he began working to extract a half sphere of ice from the iceberg. The process was a bit more difficult than it had been when he practiced at home. In his kitchen, Stern was able to create an ice lens in about five minutes – at the beach, it took him more like 45 minutes. His first four pieces cracked, but finally the fifth one held together, and Stern popped it into his 3D printed lens holder. Then it was time to shoot some images. Stern had only 60 seconds to take his photographs before the lens melted.
The images really are beautiful – foggy, surreal, and almost ghostly. Luckily, he happened to be at a hauntingly beautiful location already, so he just pointed and snapped, and ended up with soft-focus pictures of the icebergs and people moving among them. Stern is not the only one to use 3D printing to hack a camera in a creative way. Makers have used the technology to create everything from reinvented film cameras to camera rigs for the disabled. Now that everyone has cameras available on smartphones, actual physical cameras are being seen by many as obsolete – but serious photographers beg to differ. It’s fascinating to watch a new technology used to reinvent an old one; 3D printing is allowing photographers and hobbyists create cameras that would have been extremely difficult, if not impossible, to create using any other means. Stern’s work with photography goes far beyond his most recent ice lens project. You can see more of his beautiful images, and read about his other projects, on his website.

Researchers Use Aerosol Jet 3D Printing to Develop Neuronal Interface with More Anti-Inflammatory Ability https://ift.tt/2PYA7j4 3D printing has been used in the past to help treat degenerative diseases, or at least make it easier to cope with them. In terms of neurodegenerative diseases, implanted prosthetic devices are often used, but adverse biological reactions in host tissues can result in signal failure. it’s important to create tissue that can mimic the mechanical and structural properties of neural implanted devices, and while flexible polymer-based implants have helped to alleviate some injuries, the mechanical stress doesn’t quite match brain tissue. That’s why a lot of research has been conducted about using conductive polymer (CP) composites or conductive hydrogels to coat the devices so the biocompatibility and electrochemical performance of neural electrodes can be improved. But, a team of researchers from China and Taiwan say that it’s more important to design biocompatible coatings for implanted devices that mimic mechanical and structural properties of brain tissues, so tissue responses after long-term utilization can be reduced. The researchers believe that 3D nanostructural coatings should be developed for the insulated regions, and not the implant electrode sites, so implants can interface with nearby brain tissues with more stability. They explained their findings in a recently published paper, titled “Multifunctional 3D Patternable Drug-Embedded Nanocarrier-Based Interfaces to Enhance Signal Recording and Reduce Neuron Degeneration in Neural Implantation.”
The researchers used aerosol jet 3D printing to develop a neuronal interface with prolonged anti-inflammatory ability, structural and mechanical properties that mimicked brain tissue, and a sustained nonfouling property in order to inhibit tissue encapsulation.
They created a new 3D nanocarrier-based neural interface that could possibly be used to support long-term neural implantation, as well as achieve better therapy for chronic and degenerative diseases. The researchers used a “novel combination of antioxidative zwitterionic nanocarriers and nanomanufacturing technology” to make the interface. The team developed a new type of anti-inflammatory nanogel, based on the amphiphilic polydimethylsiloxane-modified N, O-carboxylic chitosan (PMSC) incorporated with oligo-proanthocyanidin (OPC), called OPMSC.
The team directly fabricated OPMSC nanogels onto a membrane using aerosol jet printing technology, because it is a low-temperature technology. When developing neural implants, mechanical properties are the main concern, which is why the researchers conducted a tensile test, among other experiments, on their new 3D nanocarrier-based neural interface, which was also implanted into rodents.

Printing via 3DPrint.com | The Voice of 3D Printing / Additive Manufacturing https://3dprint.com October 26, 2018 at 04:30AM Cranfield University Study Titanium Oxidation During WAAM 3D Printing https://ift.tt/2Pmj7Go Wire and arc additive manufacturing, or WAAM, is an effective technique that has been used in the aerospace, maritime and other industries. The technology involves the use of a metal wire and an electric arc like that used in welding, and it’s faster and less expensive than other methods of additive manufacturing. However, it’s not a perfect process. In a paper entitled “Oxidation of Ti-6Al-4V During Wire and Arc Additive Manufacture,” a group of researchers discuss a common issue in WAAM – that of oxidation. Oxidation frequently happens during WAAM due to the high reactivity of titanium with oxygen at high temperatures. A sign of oxidation is discoloration due to a brittle oxygen-enriched layer near the surface (Alpha Case), which can be detrimental to the part’s mechanical properties. The researchers investigated the oxidation of a titanium alloy during WAAM to “determine the mechanism and main process parameters controlling this phenomenon.” Plasma-transferred arc and wire deposition samples were manufactured by changing either deposition parameters or oxygen levels in the fusion atmosphere. The samples were characterized by visual inspection, optical microscope, scanning electron microscope and tensile mechanical testing.
Temperature and exposure time, the researchers discovered, play more important roles than oxygen levels during the WAAM oxidation process. They conclude that as long as the shielding environment contains oxygen, oxidation occurs if temperature and exposure times are high enough, even if the oxygen levels are low. Several overall conclusions were reached by the tests the researchers performed on the samples:
Careful control of parameters can mitigate the effects of oxidation, but it remains an issue, particularly in the aerospace industry where titanium components are commonly used. Because temperatures are so high during WAAM, oxidation tends to happen and create the hard, brittle, difficult-to-machine outer layer known as Alpha Case. The authors of this paper, however, are able to offer more insight into the condition and the potential for avoiding the most serious effects. Authors of the paper include Armando Caballero, Jialuo Ding, Yashwanth Bandari and Stewart Williams. Discuss this and other 3D printing topics at 3DPrintBoard.com or share your thoughts below.
Printing via 3DPrint.com | The Voice of 3D Printing / Additive Manufacturing https://3dprint.com October 26, 2018 at 04:06AM SOLIDWORKS and a Form 2 Used to Make 3D Printed Micro Check Valve for IV Fluid Transfusion10/26/2018 SOLIDWORKS and a Form 2 Used to Make 3D Printed Micro Check Valve for IV Fluid Transfusion https://ift.tt/2O6EUNx Check valves are devices that allow for flow in one direction, while at the same time preventing flow in the opposite direction. The design of this device continues to improve as technology advances, and check valves have been made out of everything from graphene and hydrogels to shape memory alloys and piezoelectric materials. Micro check valves are self-controlled, relying on pressure changes for operation, and are often used in areas of biomedical engineering like drug delivery and surgical procedures, due to how cost effective and quick they are to fabricate. A group of researchers from Alfred State College, one of eight Colleges of Technology within the State University of New York (SUNY) system, recently wrote a paper, titled “3D Printed Micro Check Valve for Biomedical Applications,” detailing how they used 3D printing and SOLIDWORKS modeling to develop a novel, imprinted micro check valve for a specific biomedical application: IV transfusions.
The initial design of the micro check valve used ball and socket parts, where the 2 mm ball would block the smaller channel from any backward flow and then settle into a perforated socket so fluid could pass. Then, the team added bars to hold the ball in the chamber and used a cap-like bottom to cover the smaller channel. Small tabs were added, which connected to these bars so the ball wouldn’t rotate.
The cap on the bottom makes a tight seal on the valve inlet, so backward flow is prevented. This design does not use a spring loaded ball, but rather relies on the laws of pressure flow to only initiate a one-way flow. A Form 2 3D printer was used to make parts, modeled first in SOLIDWORKS, out of ABS. The three parts that made up the check valve – the ball, valve inlet, and perforated ring outlet – were all 3D printed at the same time. The completed valve was coated with a thin layer of parylene to make it safe for use inside the human body. The check valve was made in two sizes, with the larger one being used as a visual representation of what was happening inside the normal-sized valve, which was used for gathering data and test results. The team conducted multiple tests on the two check valves to prove that they would allow fluids to pass freely through, while also preventing any backward flow, including subjecting the 3D printed check valves to a certain pressure, as well as seeing if any liquid would freely flow through it without much pressure used.
Co-authors of the paper are Abdou Mbaye, Colton Kreamer, Lukas Zink, Mitchell Fredenburg, and Reza Rashidi. 3D printing has been used multiple times to make valves for biomedical applications. Now, a micro check valve can be added to the list. Discuss this and other 3D printing topics at 3DPrintBoard.com or share your thoughts below.
