WHAT CAN YOU 3D PRINT TODAY ??

Published

on

Imagine a time when you can 3D print anything and everything in your own house or your neighborhood.If you need a dish plate, a broken piece of your device, a machine part or just a toy. Or why just a toy, you can 3D print your jewelry, your broken car parts, or your dream house in which you want to live your whole life. Or why just a house, your doctor can print a prosthetic arm, skin or an organ in the worst case you need it. Many of these things are achieved and the rest of these will be achieved in near future and this time is not far away from the present. Then the only limitation to print will be your imagination. 3D printing is revolutionizing the present with its miracle like transformation in technology. This article will cover all you need to know about 3D printing and the objects you can 3D print in various industries in short.

WHAT IS 3D PRINTING?

3D printing (or additive manufacturing) is a process which is used to print an object in three-dimension, layer by layer under computer control. Unlike material removed from a stock in the conventional machining process, 3D printing or additive manufacturing builds a three-dimensional object from computer-aided design model by successively adding material layer by layer.
Objects can be of any shape and are produced using digital model data from a 3D model. It can also be produced by an electronic data source such as an Additive Manufacturing File (AMF) file. Stereolithography (STL) is one of the most common file types that 3D printers can read.

GENERAL PRINCIPLES OF 3D PRINTING

1. Modeling

3D printable models may be created in many ways. It can be created with a computer-aided design (CAD) package, via a 3D scanner, or by a plain digital camera and photogrammetry software. To reduce the errors, 3D printed models should be created with CAD and the errors can be corrected easily before printing, allowing verification in the design of the object before it is printed.

2. Printing

The CAD file needs to be converted into the STL file and this needs to be processed by a piece of software called a “slicer,” which converts the model into a series of thin layers and produces a G-code file containing instructions to a specific type of 3D printer. During the 3D printing process, this G-code is used to instruct the printer, which is done using a 3Dprinting client software.

3. Finishing

The resolution produced in 3-dimensional printing is sufficient for many applications, but when a slightly oversized version of the object is desired then removing material to get higher precession and better surface finish with a higher-resolution subtractive process is better.

What objects can a 3D printer print?

A coffee mug, high heels, hanging lights, iPad stand, acoustic guitar, a wheel rim or a whole car, a house plan, a cement wall or a whole house, a prosthetic arm, synthetic skin, bone….. the list is too long. So let us see a detailed list in each of the industry, what we can print and what cannot be printed.

Check this list-

1.Daily household things

It will be fun if we can customise our daily used objects as per our desire. You will not need to search some remote shop or ask your friend where I can find it. Your object, your design, your colors, sounds nice, but of course, we cannot print with any material. Hope this can also be done in 3D printing in coming years. Let us see a list of some objects-

1. Your custom iPhone cover

 

2. Coffee mug

 

3. High heels

 

4. Hanging lights

 

5. Bugdroids

 

6. iPad stand

 

7. Shakuhachi Flute

 

8. Acoustic Guitar

Industrial engineer Scott Summit made this guitar out of nylon powder.

 

 

 

 

9. Fabrics

 

10. 3D Printed Bikini – N21

 

11. Soap dish

 

 

12. Earbud holder

 

And many more beautiful things like these-

platform jack

sound amplifier

headphone stand

modular mounting system

plastic wrench

Capsule planter

Fidget spinner

pen holder

big straw glasses

 

wooh.. that was a lot of things.

 

2. Automobile Industry

companies are adopting 3D printing for jigs and fixtures.3D printing jigs and fixtures can lower costs, provide lighter and more ergonomic tools, and more. Furthermore, it has shown a consistent reduction in lead-time by 40% to 90% and cost reduction up to 60%. 3D printing rapidly designs a prototype saving precious time of the design team allowing them to concentrate on other important design aspects. In 2014, Local Motors printed the first 3D-printed car from an ABS carbon-fiber blend (about 80/20 respectively) called Strati.

Today, the company has three models and an autonomous electric-powered shuttle named Olli. Also, Honda released a newer version of the Micro-Commuter in October 2016. A single-seater with about a 50-mile driving range, the body and majority of the panels on the Micro-Commuter are 3D printed.

Yes these cars are 3D printed

 

 

3. Architecture Industry

Architects, Engineers, and Construction (AEC) professionals understand the paramount importance of accurate and tangible scale models. It helps them and their clients visualize ideas realistically and vividly. Traditional ways of designing and assembling a scale-model are time-consuming, and are very costly, and rely heavily on skilled craftsmen.

3D printing will revolutionize the way architects designs and innovate their ideas. 3D printing for architects empowers them easily create complex, accurate and durable scale models quickly and cost-effectively. The 3D printed models can be used to demonstrate and impress the clients, seizing more opportunities, all this in a matter of clicks.

 

 

4. Aerospace Industry

From complex engine parts to cabin interiors, aerospace companies are turning to the capabilities of 3D printing to produce better performing parts for their commercial aircraft and/or spacecraft. The ongoing development of the industry itself will surely lead to more breakthroughs in the near future. In the aerospace industry, the benefits of adopting 3D printing will be reduced material weight, part consolidation, improved part performance, virtual warehouse, and many more.

 

 

5. Electronics Industry

With 3D printing replacing the conventional manufacturing processes, in the electronic industry opportunities are growing in terms of ease of customising a product for a user or a customer. The production of relatively low volumes is possible in the industry because of 3D printing. Like for example, if the small startup needs to make 30 pieces of their product, by the conventional process the initial setup would be too costly and it will not justify the cost of a single piece of product.

 

 

6. Foundry

Producing sand molds and cast metal parts is a relatively straightforward job and suitable for automated methods. The most common method is to produce aluminum patterns, fabrication of which is often very difficult, expensive and time-consuming. These aluminum patterns are machined using a CNC machine. The biggest problems with this approach are the high cost and long lead time. On the CNC machine, the intricate gate and runner systems cannot be produced. So, the gate and runner system are cut from Ren board and then hand carved to the finished shape.

The problems associated with traditional pattern production are many and this process takes much time and money. So foundries have long been interested in 3D printing. With 3D printing systems available, foundries can fabricate patterns with either inkjet-based technology or FDM Technology. This results in savings, in cost, labor and time, ultimately speeding new product development.

 

 

 

7. Medical

3D printers are used to manufacture a variety of products in the medical industry. It includes those products with complex geometry or features that match a patient’s unique anatomy.Sometimes a standard design is copied to make multiple identical copies. Other devices are called patient-specific devices. This type of devices is created from a specific patient’s imaging data.

Commercially available 3D printed medical devices include:
Instrumentation,
Implants (e.g., cranial plates or hip joints), and
External prostheses (e.g., hands).

Manufacturing of living organs such as a heart or liver via 3D printing process is in early stage of development. Scientists are still researching such methods and process.

Things that can be 3d printed are-

Tissues with blood vessels

 

Low–Cost Prosthetic Parts

 

 

Drugs

Tailor-made sensors

Medical Models

bone

 

valve

ear cartilage

 

 

medical equipment

Cranium Replacement

 

 

8. Jewelry

Many startups have been seen in this field recently.A 3D printing startup from Hong Kong, called POESIS, has successfully completed its crowdfunding campaign for a smart 3D printing jewelry system. This system allows anyone to easily create unique and resilient rings and bracelets. A study by YouGov, a prominent data research firm, indicated that marketing efforts by high-end jewelers for Millennials are proving to be inefficient. This market-segment is spending approximately $49 billion annually on products within various luxury categories, however, only a limited percentage of this money is being spent on fine jewelry.

How Google is using AI to Prevent Blindness in Diabetics

Published

google ai to prevent Blindness in Diabetics

Artificial Intelligence is in its development stage, and at many times we find it hard to find the best application of the technology for the betterment of human society. I think it is similar to the situation faced by us 70 years back from now when we didn’t know that what to use a computer for.

Many companies including Google are trying to find ways in which AI can be utilized in the best way possible to help simplify the challenging problems faced worldwide.

This story was recently featured on the homepage of Google. It shares a story about how a team at Google is using AI to help doctors prevent blindness in diabetics.

Google research scientist Varun Gulshan started this project in his home country India.

The Problem

diabetic

With seventy million folks with diabetes, India encompasses a growing drawback with diabetic retinopathy. It creates lesions within the back of the membrane that may result in total visual impairment.

Eighteen per cent of diabetic Indians already suffer from it. With 415 million diabetics in danger for visual impairment worldwide, it may be a world concern.

But the great news is that permanent vision loss isn’t inevitable. For those that square measure diagnosed early enough, medications, therapies, exercise and a healthy diet square measure extremely effective treatments for preventing additional harm.

The Tricky Part

If Google’s artificial intelligence may facilitate build designation diabetic retinopathy easier by accurately deciphering retinal scans, then maybe the visual modality of millions may be saved.

The difficult half was making a data set for the AI model to train on a task that involves grading and labelling all the scans one by one for various grades of severity.

Finding that downside would eventually need an outsized team of ophthalmologists whose grading of the scans would inform the AI model. And the team also requires quality data to provide more accurate information.

Training the model

The team was assisted by ophthalmologists at Aravind and Sankara Nethralaya to label the membrane pictures. when a couple of short months, the model was trained to spot key markers of diabetic retinopathy, like nervous tissue injury, swelling and haemorrhaging.

And with a bigger knowledge set, Gulshan was positive that they might build the model even additional correct.

They were successfully able to train the model and make a device from it.

How the Google AI Model Works to Detect Diabetic Retinopathy

  1. Over 50 ophthalmologists have manually reviewed more than 1 million anonymous retina scans, rating each for the level of diabetic retinopathy present.

  2. Each scan is reviewed multiple times and is graded manually on a scale of 1 (no diabetic retinopathy signs present) to 5 (extreme signs present).

  3. Each scan is reviewed multiple times and is graded manually on a scale of 1 (no diabetic retinopathy signs present) to 5 (extreme signs present).

  4. Once the algorithm has been trained, it can be used to power an application called an Automated Retinal Disease Assessment (ARDA). ARDA allows a user to upload a retina scan for instant analysis of diabetic retinopathy.

Verdict

Getting a diabetic retinopathy diagnosis will cause higher outcomes overall. ‘If you notice retinal unwellness at associate degree early stage after they don’t would like treatment’, Dr. Cuadros says, ‘it’s still a chance for the patient to know that polygenic disorder is starting to have an effect on their body.

This was just one of the ways in which artificial intelligence could be used to solve compelling problems faced by millions of people. Visit Google stories for more such stories.

How does Apple face id works

Ever wondered how does Apple Face ID works. Apple first introduced the technology of Face ID for authentication purposes. Since then many smartphone manufacturers started giving Face ID for their devices in the budget range. Hail that notch which took the industry to cut the portion of the screen and play as bezelless display. In this article we will take a closer look of that notch particularly the Face ID and unravel the working of that technology. Will also be looking at some of the downsides of having a Face ID, cause ofcourse noting is safe in this world.

Most of our digital information are stored on Phones and it’s important to protect that information. Face ID is the next big step in that direction. Face ID provides intuitive and secure authentication enabled by the state-of-the-art TrueDepth camera system with advanced technologies to accurately map the geometry of your face.

With a simple glance, Face ID securely unlocks your iPhone X. You can use it to authorize purchases on the Apple Store.

The dot projector embedded in the notch produces over 30,000 invisible rays to create a depth map of your face and also stores an infrared image of your face. Apple’s A11 bionic chip also plays a significant role, it transforms the depth mapping and the infrared image into a mathematical representation and compares that representation to the enrolled facial data.

So what happens if my face changes like if i trim by beard or apply makeup or some crazy stuff, or even if I show half of the face, how does it recognise me?

The answer lies in the fact that it maps your face but does not open until you open it manually using your pin, it then knows you are the authorised personnel and it updates the mathematical representation, so it remebers how your face look under different conditions. It actually keeps learning over time or we can say updating that mathematical representation over time. So it becomes highly accurate.

The mapping of face is a very high dimensional data and needs a lot of computing power to work fairly fast. A part of the A11 Bionic chip’s neural engine — protected within the Secure Enclave, performs this task with an ease. Face ID is designed to work with hats, scarves, glasses, contact lenses, and many sunglasses. Furthermore, it’s designed to work indoors, outdoors, and even in total darkness.

To start using Face ID, you first need to enroll your face. You may do this during the initial set up process, or at a later time by going to Settings > Face ID & Passcode. Face id works best at arms length and very well even when the phone is inclined to certain extent.

Security safeguards

Security is important to protect information on our devices. Face ID uses the TrueDepth camera and deep learning for a secure authentication solution. Face ID data – including mathematical representations of your face – is fully encrypted and protected with a key available only to the Secure Enclave.

The probability that a random person in the population could unlock your device is approximately 1 in 1,000,000 which 1 in 50,000 for Touch ID. Face id only takes five unsuccessful attempts to prompt you to enter your passcode.

Face id also looks at your eyes when unlocking the device, so if you’re asleep then for sure nobody will be able to unlock it, unless they wake you up. Face id cannot be fooled by photographs as it does not have any depth, it’s designed to protect against spoofing by masks or other techniques.

Furthermore, you must enter your passcode for additional security validation when:

  • The device has just been turned on for first time or restarted.
  • The device has been idle for more than 48 hours.
  • The device has received a remote lock command.
  • After five unsuccessful attempts to match a face.
  • After initiating power off/Emergency SOS by pressing and holding either volume button and the side button simultaneously for 2 seconds.

Privacy

Some less known fact about Face ID is that the data doesn’t leave your device and is never backed up to iCloud or anywhere else. Only in the case that you wish to provide Face ID diagnostic data to AppleCare for support only then information will be transferred from your device. And even in that case data isn’t automatically sent to Apple; you have to first review and approve the diagnostic data before it’s sent.

If your iphone gets lost, then you can choose to delete the data on the device from another Apple device or Apple care cneted, the face id data also gets deleted.

Even if you don’t use Face ID the true depth camera is active all the time, it looks for your face, it dime the light when you are not looking at it, or pause the video when you are not looking at it.

Other third party app developers can also use the face id for authentication purpose, but the face id data is not shared with the developers.

Safety

The true depth camera is safe to use under normal conditions, it has gone through international safety standards, the infrared rays will not cause any harm to eyes or skin, due to its very low output power.

Some cameras may be able to detect the infrared light though we may not see it directly and it is normal.

Accessibility

Users with physical limitations can also use the Face ID, the enrollment doesn’t require the full head range of motion it mostly depends on the way you look at your device at the time of registering your face.

Drawbacks of Face ID

The Face ID can be easily tricked by twins or children under 13 having the same statiscal features. May also be tricked with spoofing neural networks which approximates your face fretty accurately. Face ID cannot be used for authorisation of family purchases. And it definitely does not work in landscape mode as they have shown in the commercial.

Verdict

Apple’s face id is the next big step in security and authentication. The whole Face ID concept is new, as of now a lot of manufacturers started using the face id as a new security measure to unlock your device, the future of Face ID seems bright.
