The wire feed 3D printing

Posted on Updated on

According to researchers at Oak Ridge National Laboratory Andrzej Nycz and Voestalpine Böhler Welding, “We achieved a precise geometry for the components by using real-time feedback sensors to correct for abnormalities. Because metal printed walls represent the basic building blocks of parts manufactured with big area additive manufacturing, we expect the same stable properties to hold for parts printed with complex geometries. Not so heavy metal. A good example is wire-feed 3D printing. Mechanical postprocessing like milling and lathing is almost always necessary. Typical fields of applications are automotive, aerospace, shipbuilding, tool making as well as service and maintenance. This additive manufacturing (AM) technique is finding favor in industries like aerospace and heavy equipment, where oversized, monolithic structures are desirable.

The Additive Report has posted numerous stories on wire-feed AM systems in the past two months.
Metallic 3D Printing (M3DP) is a Wire and Arc Additive Manufacturing (WAAM) process and works with a plasma arc and welding wire. The plasma torch is moved by a CNC gantry system along an arbitrary path and creates a weld pool on a substrate plate. A material deposition is achieved by adding wire into the weld pool. The desired part can be generated by putting one deposition over the previous one”.

4D printer could accelerate technology

Posted on Updated on

American Chemical Society is researching about 4D Printer. They have the ACS 255th National Meeting & Exposition in New Orleans.
4D printer could accelerate technology. Scientists report that they have developed a powerful new printer that could streamline the creation of self-assembling structures that can change shape after being exposed to heat and other stimuli.
American Chemical Society says this unique technology could accelerate the use of 4D printing in aerospace, medicine, and other industries.:)

Responsible use of high risk 3D Printed medical devices

Posted on Updated on

Standard parts that are too complex or too expensive to be built by other production techniques.
Now, “standard” 3D printed medical devices are responsibly use of high risk designs through rapid prototyping with 3D printing.
They can test new medical devices on realistic medical models to quickly gather clinically relevant performance feedback, without scheduling expensive animal/cadaver surrogate testing.
The guidance defines AM as “a process that builds an object by sequentially building 2-dimensional (2D) layers and joining each to the layer below, allowing device manufacturers to rapidly produce alternative designs without the need for retooling, and to create complex devices built as a single piece.”
This manufacturing process is used extensively in the aerospace, architecture, consumer products, and, more recently, medical industries.

3D Printing technology to make Rolls Royce’s parts

Posted on Updated on

3D Printing technology to make Rolls Royce’s parts and how it will work. Future is 3D Printing.

Using 3D Printing techniques they are able to make shapes that they never couldn’t with standard manufacturing. According to Rolls Royce’s Head of Additive Layer Manufacturing, Mr. Neil Mantle, is using the technology to develop better and more efficient aerospace components.:)

4D Printing value $537.8 Million by 2025

Posted on Updated on

According to a new market research report, “4D Printing Market by Material (Programmable Carbon Fiber, Programmable Wood – Custom Printed Wood Grain, Programmable Textiles), End User (Aerospace, Automotive, Clothing, Construction, Defense, Healthcare & Utility) & Geography – Global Trends & Forecasts to 2019 – 2025 ”.

4D printing technology, being based on 3D printing technology, proposes a new business model to cater to this need of today’s businesses by lowering capital requirement, reducing time-to-market, and facilitating lower requirement of holding an inventory, thereby increasing the efficiency of the business.

Also, the self-transformation ability of 4D printed objects allows after-use-disposition of the object easier as it reacts to external stimuli, thus helping to maintain a sustainable environment in today’s situation of limited resources.

3D Printing Material: Metals

Link Posted on Updated on

3D Printing Material: Metals

According to the 3D printing,” using plastic has limited scope due to the fragile nature of plastic.  Any serious manufacturing is not possible without using metal.  3D printing using metal or Metal Additive Manufacturing has seen significant growth recently. Metals are 3D printed by melting metal powder using a laser beam to fuse it into a solid part.  Metals used for 3D printing include stainless steel, aluminium, bronze, copper, silver, gold, alloys of titanium, cobalt, titanium, nickel, among others.

3D printing of metals is used in several industries including aerospace, automobile industry, jewellery, medical, among others.  The medical industry, for example, dental and orthopaedics benefits with the ability to customize parts for specific individuals.  The quality of the 3D printed metal objects is comparable to objects made by conventional manufacturing processes.  Manufacturing based on 3D printing results in very little waste compared to conventional manufacturing.  Therefore Metal Additive Manufacturing continues to grow and become a significant part of manufacture”.:)
