3D printing into mainstream manufacturing

Radical new high-speed liquid technology could bring 3D printing into mainstream manufacturing

March 18, 2015


A new 3D-printing technology developed by Silicon Valley startup Carbon3D Inc. enables fabricated objects to rise from a liquid media continuously rather than via a series of 2D layers.

Described in the journal Science on Monday March 16, the technology enables ready-to-use products to be made 25 to 100 times faster than other methods, and promises to advance the industry beyond basic prototyping to 3D manufacturing, according to the company. It creates previously unachievable precision geometries that open opportunities for innovation in major industries such as healthcare, automotive, and aviation.

Light-controlled precision fabrication

The technology, called Continuous Liquid Interface Production (CLIP), manipulates light and oxygen to fuse objects in liquid media. It works by projecting beams of light through an oxygen-permeable window into a liquid resin to rapidly transform 3D models into physical objects.

Working in tandem, UV light, which triggers photo polymerization, interacts with oxygen, which inhibits the reaction, to control the solidification of the resin, creating commercially viable objects that can have feature sizes below 20 microns, or less than one-quarter of the width of a piece of paper. This is the first 3D-printing process that uses tunable photochemistry instead of the layer-by-layer approach that has defined the technology for decades.

Faster, stronger, predictable

CLIP enables a very wide range of materials to be used to make 3D parts with novel properties, includingelastomers, silicones, nylon-like materials, ceramics and biodegradable materials, and could allow for synthesizing novel materials that can advance research in materials science.

Conventionally made 3D printed parts are notorious for having mechanical properties that vary depending on the direction the parts were printed because of the layer-by-layer approach. Much more like injection-molded parts, CLIP produces consistent and predictable mechanical properties, smooth on the outside and solid on the inside, the company says.

“By rethinking the whole approach to 3D printing, and the chemistry and physics behind the process, we have developed a new technology that can create parts radically faster than traditional technologies by essentially ‘growing’ them in a pool of liquid,” said Joseph M. DeSimone, professor of chemistry at University of North Carolina-Chapel Hill and of chemical engineering at North Carolina State and CEO of Carbon3D, who co-invented the method.

“In addition to using new materials, CLIP can allow us to make stronger objects with unique geometries that other techniques cannot achieve, such as cardiac stents personally tailored to meet the needs of a specific patient,” said DeSimone. “Since CLIP facilitates 3D polymeric object fabrication in a matter of minutes instead of hours or days, it would not be impossible within coming years to enable personalized coronary stents, dental implants or prosthetics to be 3D printed on-demand in a medical setting.”

DeSimone revealed the technology at a TED talk Monday March 16 in the opening session of the conference in Vancouver, British Columbia.

Abstract of Continuous liquid interface production of 3D objects

Additive manufacturing processes such as 3D printing use time-consuming, stepwise layer-by-layer approaches to object fabrication. We demonstrate the continuous generation of monolithic polymeric parts up to tens of centimeters in size with feature resolution below 100 micrometers. Continuous liquid interface production is achieved with an oxygen-permeable window below the ultraviolet image projection plane, which creates a “dead zone” (persistent liquid interface) where photopolymerization is inhibited between the window and the polymerizing part. We delineate critical control parameters and show that complex solid parts can be drawn out of the resin at rates of hundreds of millimeters per hour. These print speeds allow parts to be produced in minutes instead of hours.

Custom 3D Printing

3D printing custom products is one of the newest phenomena’s today. This technology has allowed for the precise creation of very diverse and intricate shapes & figurines, opposed to traditional forms of manufacturing. Some materials and 3D printers offer detail levels which are less than 15 microns. Some of these materials offer full color options, as well as mechanical properties. Where I’m getting at with the materials, is that for whatever need you’re seeking in a product, 3D printing likely offers a material solution. Many companies and services have capitalized on this great technology known as 3D printing, and are opening the door to cutting edge laser technology for their clients. Through 3D printing, true customization is offered. Let me elaborate.

 

For 3D printing to work, a design has to be created on a computer. This computer file will then be sent to the actual 3D printer, or the machine that will do the manufacturing. This machine will then produce a product in accordance to the design sent to the machine. This product will be made out of a material specified by the product developer. Some of these materials include precious metals like gold, silver, or platinum, a variety of ABS plastics, stainless steel, and full color sandstone. There are even a variety of wax cast-able materials for creating jewelry. What am I getting at with all of this? If a product can be designed or created for a person, it can be made through 3D printing. This means that artists and developers can create truly 100% unique products. Entirely unique.

 

What does this include? Well, pretty much anything that can be sculpted & designed on a computer. There are tons of custom made products that are specific to each designer. There are companies that actually 3D print clients’ faces. There are businesses that create custom video game characters coming from your favorite computer games. There are custom designs made for unique purposes; for example: in the United Kingdom, a team of cyclists had custom bike helmets made. 3D printing has been used to create architectural pieces to present to clients. It has been used to create models for future products to be further developed, such as prototypes. Other products have been made such as custom board game pieces and scale models to be painted and played within war games. Accessories such as iphone cases and various custom jewelry have been developed. It’s almost pointless to keep naming examples because there are simply too many to cover. Just imagine this. If it can be drawn on a computer screen through various free and paid softwares, it can be manufactured through 3D printing. Not only that, but the models designed are designed differently; traditional forms of manufacturing simply don’t offer the same build capabilities when it comes down to actually creating the products. 3D printing offers a quicker solution that has the potential to create more diverse models. These models are often more inexpensive than traditional forms of manufacturing such as machining. Regardless, this industry is going nowhere but up. Just imagine where this industry will be 20 years from now.

What Exactly Is 3D Printing as well as Why Is It Essential Now?

3D Printing describes a procedure of producing a three-dimensional item from an electronic data using a gadget that adds layers of material one after an additional. It was designed by Charles W. Hull, nevertheless the initial strong version was made by Hideo Kodama of Nagoya Municipal Industrial Research Institute in 1981; and also has since developed greatly because of demanding efforts through research study and development technological development. The first 3D printing machines were large, pricey and of limited usage. The terms 3D printing and also 3D ink-jet printer is typically mentioned with Jim Bredt as well as Tim Anderson, graduate students at the Massachusetts Institute of Technology, which enhanced an inkjet ink-jet printer to give binding option onto powder instead of ink onto paper. These 2 are the owners of 3D printing company Z Company.

free-seo-tools2

3D printing or as practically recognized “additive production”, is a procedure where physical things are constructed layer by layer by a sophisticated, computer-controlled tool. It works much like inkjet ink-jet printers by depositing shades on a piece of paper to produce a photo – nevertheless in 3 measurements whereas an inkjet laser printer works in 2 dimensions. This printing process uses materials like plastic, metal, glass as well as porcelains. It can additionally utilize a wide variety of shades throughout the printing procedure. On the various other hand, subtractive production as well as machining usually described as “conventional manufacturing approaches” up until lately did not make use of any sort of information technology element or model-based meaning. Standard approaches concentrated on milling and also grinding objects.

The general concepts of 3D Printing consist of version slicing that usage designs or virtual plans of Computer Aided Style (CAD) or computer animation modeling software and also “slice” them into electronic cross-sections for the home appliance to make use of as a prepare for the printing process. The motion will depend upon the expected item and also the 3D machine; then the binding material is deposited on the develop bed or platform up until material layering is completed and the end product which is the 3D design is “published.” It is very important to keep in mind that the virtual model as well as the bodily version are almost similar. This process uses a basic data user interface between CAD software program and the machines known as the STL file style that estimates the form of a part or setting up making use of triangular elements. Furthermore, throughout the printing processes the equipment reads the layout from a.STL file and also down payments succeeding layers of liquid, powder, paper or sheet material and also develops the design from a collection of random samples. The layers, as per the CAD model, are fused consistently to produce the final form. The 3D printing benefit is that it can create any type of form or geometric feature. Laser printer resolution describes layer density and it is around ONE HUNDRED micrometers (A?Amm) while the places (3D dots) are 50 to 100 A?Amm in size. A solitary typical version could take several hours to even numerous days to publish; yet this will certainly vary depending on the technique utilized, the dimension, and the shape of the design. Finally, the remaining phase of the 3D printing process is called the finishing phase. In the finishing phase the additive manufacturing methods apply several products in the course of the print and also are capable of printing at the same time in numerous colors and even color mixes.

Rapid manufacturing has actually been enabled because of the advancement in RP modern technology which has introduced materials that are really applicable for last 3D production. 3D printing for quick production generates advantages as a result of its relatively low-cost production of tiny parts and also this benefits enthusiast as well as lovers’ which otherwise are funding strapped. Although it is a reasonably brand-new modern technology, Fast Production is being acknowledged as a “following level” technology by lots of printing professionals. It has several appealing procedures like Laser Sintering (LS), which is a technique utilized to develop items from powders. This strategy is still significantly in its early stage and also has actually not yet been fully accepted by the mainstream.

Mass personalization is obtaining notability as business have actually produced services where customers can tailor items using on the internet based modification software, and order the resulting items as 3D published unique items. These new services are described as cloud 3D printing solutions. These solutions now equip companies to develop custom-made designs as per their clients’ needs as well as download them for printing at a charge. This has brought huge benefits to those who could not otherwise manage the current high expense 3D printing systems.

3D printing additionally equips mass production. The current slow-moving print speed of 3D ink-jet printers restricts their usage for mass production at tiny volume prints. This obstruction is being overcome through the intro of many merged filament equipments which now supply a number of extruder heads. These high expenses printers can be made use of to print in numerous shades, with diverse polymers or just simply by making a number of prints instantaneously. This has actually increased the overall 3D printing rate during multiple manufacturings as well as getting rid of capital price. Unlike the multiple machines, multi-material equipments could not make the same duplicates of the very same component. Nevertheless they do supply multi-color as well as multi-material features. The 3D Printing rate enhances in proportion to the variety of integrated heads and also they attain high power conservation as a result of the common heated print quantity. For that reason, 3D printing has actually produced numerous chances for folks looking to take advantage of the technology. It is opening up doors to greater performance, boosted high quality, higher efficiency and numerous cost-effective opportunities.

3G War in India

3G War in India

When some countries are boasting of the 4G technology, in India, there is a war like situation among the telecom giants. Everyone including the likes of Bharti group, Vodafone, BSNL and Tata have recently launched their 3G services in India. The price sensitive Indian market is still in its infancy when we talk about ‘3G technology’. Till recently the mobile phone has been used for the basic purpose of calling and text messaging. It is now that these players are trying to develop a wider scope of mobile telephony in the country. And the timing is perfect. The Indian middle glass is growing at an unprecedented rate. Secondly, it is willing to spend more than ever before and it is not hesitating to try newer things. It is willing to pay for convenience now. People are surfing the net on their mobile phones, they are buying smarter phones, they are paying bills online and what not.

Amid this change, this change which is very swift in nature, Telecom majors are trying their luck with this expensive technology. With as much as Rs 68000 crore invested in purchase of the 3G spectrum, I do hope that these companies have a good luck.

Let me remind you that the European market, where 3G was introduced in 2003, turned profitable for the mobile phone companies 2-3 years back. So it could be a long wait for the companies and especially when they have invested so much. But as I said the Indian market is transforming at a stupendous pace so I think the mobile phone companies here won’t have to wait that much.

Currently, a lot of them are using experiential marketing to develop the market. Bharti Airtel has launched a campaign wherein it has several red coloured buses or the famously known “3G buses” on the move in some of the major cities. Users can step into these buses to get an experience of the 3G mobile services like mobile TV, video calling and online gaming. Apart from that they are also trying to induce some excitement among their customers with the new Airtel tune. It’s Print and outdoor campaigns also scream ‘Airtel is here’. It has joined hands with Nokia for its 3G network which might be a smart move.

The Vodafone’s 3G ad campaign is brilliant. It’s success from the Zoo Zoo campaign can be judged from the fact that it has been the highest gainer in terms of number of users who have decided to change operators while keeping the number same. Zoo 3G, the new superhero of the Zoo Zoo community is everywhere be it online or offline. One can see these ads floating on YouTube, ad portals, journals, billboards etc. It is a perfect example of how integrated marketing communication is carried out and truly depicts the personality of the brand – Faster, smarter and better.

Tata Docomo has turned thousands of its retail shops in experience stores where one can come and experience the features of Tata Docomo 3G. The company also conducted a lot of outdoor campaigning activity, some of it being very innovative in nature.

Reliance new campaign for Reliance 3G is quite mundane. Though the ads go on explaining about the new services that are being offered it fails to generate any excitement about the brand. The ads lack the energy and the hoopla that has been created around 3G by other brands.

Aircel has moved up the ranks pretty quickly and I feel this is due to its connection with the Indian cricket team captain, MS Dhoni. It is offering quite a lot in the 3G network. It has been quite innovative in its offerings.

Idea 3G is again, I feel not a very good campaign by Idea. After a very successful ‘What an Idea’ sirji campaign featuring Abhishek Bachchan, the present ads haven’t done a bit to woo its audience. It is just another campaign to me. In fact I was a bit disappointed after seeing these ads.

BSNL could have hit gold when they offered the BSNL 3G services at the price of 2G. This could have been a move by the company to penetrate deeper into the country but the campaign was not really a big success. Neither was it marketed well by BSNL, nor was it easy for a customer who wanted to move on to 3G from 2G.

There are some other companies that are also betting big on this sector. The Indian mobile handset manufacturers have already started offering 3G enabled handsets at affordable middle class prices. But there is still a long way to go. Awareness is one important aspect. After creating awareness the companies must think of percolating down the pyramid and then think about increasing ARPU levels.

It is an uphill path, and a rocky one. As an example, China has had only 4% adoption of the technology after 2 years of its launch and that too when the players have been aggressive in their marketing and the government has been supportive. Only time will tell whether the Indian market would fare any better for the Telecom majors than their Chinese and European counterparts.

‘Nanoneedles’ generate new blood vessels in mice, paving the way for new regenerative medicine

Researchers used nanoneedles (orange) to inject nucleic acids into the nuclei (blue) of human cells (green), shown here with optical microscopy (credit: Imperial College London)

Scientists have developed “nanoneedles” that have successfully prompted parts of the body to generate new blood vessels, in a trial in mice.

The researchers, from Imperial College London and Houston Methodist Research Institute in the USA, hope their nanoneedle technique could ultimately help damaged organs and nerves repair themselves and help transplanted organs  thrive.

In a trial described in Nature Materials, the team showed they could deliver nucleic acids DNA and siRNA to back muscles in mice. After seven days there was a six-fold increase in the formation of new blood vessels in the mouse back muscles, and blood vessels continued to form over a 14 day period.

The nanoneedles are tiny porous structures that act as a sponge to load significantly more nucleic acids than solid structures. This makes them more effective at delivering their payload. They can penetrate the cell, bypassing its outer membrane, to deliver nucleic acids without harming or killing the cell.

The nanoneedles are made from biodegradable silicon, meaning that they can be left in the body without leaving a toxic residue behind. The silicon degrades in about two days, leaving behind only a negligible amount of a harmless substance called orthosilicic acid.

Generating new blood vessels

The hope is that one day scientists will be able to help promote the generation of new blood vessels in people, using nanoneedles, to provide transplanted organs or future artificial organ implants with the necessary connections to the rest of the body, so that they can function properly with a minimal chance of being rejected.

“This is a quantum leap compared to existing technologies for the delivery of genetic material to cells and tissues,” said Ennio Tasciotti, Co-Chair, Department of Nanomedicine at Houston Methodist Research Institute and co-corresponding author of the paper.

“By gaining direct access to the cytoplasm of the cell we have achieved genetic reprogramming at an incredible high efficiency. This will let us personalize treatments for each patient, giving us endless possibilities in sensing, diagnosis and therapy. And all of this thanks to tiny structures that are up to 1,000 times smaller than a human hair.”

The researchers are now aiming to develop a material like a flexible bandage that can incorporate the nanoneedles. The idea is that this would be applied to different parts of the body, internally or externally, to deliver the nucleic acids necessary to repair and reset the cell programming.

Ciro Chiappini, first author of the study suggested that in the future it may be possible for doctors to apply flexible bandages to severely burnt skin to reprogram the cells to heal that injury with functional tissue instead of forming a scar. “Alternatively, we may see surgeons first applying the nanoneedle bandages inside the affected region to promote the healthy integration of these new organs and implants in the body.

The controlled delivery of nucleic acids to selected tissues remains an inefficient process mired by low transfection efficacy, poor scalability because of varying efficiency with cell type and location, and questionable safety as a result of toxicity issues arising from the typical materials and procedures employed. High efficiency and minimal toxicity in vitro has been shown for intracellular delivery of nuclei acids by using nanoneedles, yet extending these characteristics to in vivo delivery has been difficult, as current interfacing strategies rely on complex equipment or active cell internalization through prolonged interfacing. Here, we show that a tunable array of biodegradable nanoneedles fabricated by metal-assisted chemical etching of silicon can access the cytosol to co-deliver DNA and siRNA with an efficiency greater than 90%, and that in vivo the nanoneedles transfect the VEGF-165 gene, inducing sustained neovascularization and a localized sixfold increase in blood perfusion in a target region of the muscle.

Sip Trunking Providers

Sip Trunking Providers

There are many SIP trunking provider that are creating waves in the market but they all connect to the same key factor which is the internet. This technology gives a lot of benefits compared to the traditional circuit based telephone calls. This new system of communicating has the intention of replacing the old traditional telephone service.

The market has come out with different internet telephony providers but all uses the internet as the medium for the service.

Companies who want to reduce their communication expenses should consider using the services of SIP trunking providers. Most of the SIP providers offer excellent discounts while giving the best features for all communication needs of the company. They are highly scalable providers that you can buy the SIP trunks gradually as the business grows. You can start with the 23 channels like PRIs but still gives high quality calls. The voice over IP plays the great tool which is run by SIP trunk providers.

Setting up the system may sound like an expensive project for the company by if you will count and outweighs the benefits that the company will incurred every month with the monthly rate of the service provider, you will have no qualms of switching to the SIP system. The system allows no additional fees for long distance call or any other fees that the local service provider charges.  There were reports that the company who uses the SIP system saves up to 80% in their monthly phone bills. Another saving on your part is there is no need to buy new hardware. The existing hardware will be utilized instead and you don’t have to worry that you will spend money on the additional trunk lines but less trunk channels that will handle all the simultaneous calls. When there is more traffic on your phones you can easily add extensions or vise versa. Not only that, there are also many upgraded  features such as call forwarding, voice mail, call waiting and most of all unlimited calling  which looks like the best idea any body can think of.

Switching to SIP trunking is fairly easy especially if you already have an internet connection. If your internet connection is connected to the same phone line connection then everything will be easy for you. A simple call to the service provider is all it takes.  Aside from the great savings the company will benefit, this offers an amazing clear connection that you will receive from your phone that is, if the internet connection provides you with good connectivity.
