Development of 3D Printing Technology

When we think about the 3D printing technology, most of us think of it as a recent development. Not many are aware of the fact that seeds of the technology were sown way back in the 1980’s. Then known as Rapid Prototyping technologies it developed into the amazing world of 3D printing. Broadly speaking a process to manufacture 3D objects of any geometrical dimension by using digital model data derived from a 3D model. This process has the entire ingredient that triggered the industrial revolution. This is because the procedures were initially considered as a quick, cost effective and more practical technique for making models for developing product in industry. The fascinating side of the story is that the main patent application for RP innovation was recorded by a Dr. Kodama, in Japan, in May 1980. Dr. Kodama did not apply for the full patent specification before the one year due date after the application, which was disastrous as he himself was patent lawyer. It was in the year 1984 when Charles “Chuck” Hull came up with the process …

3D Printing Basics for Beginners

We all have been hearing about the amazing world of 3D printing and the storm in the form of revolutionizing the manufacturing sector. This very concept will turn the current manufacturing process of machining, fabrication, casting and stamping a thing of past. So, what is it? Broadly speaking a process to manufacture 3D objects of any geometrical dimension by using digital model data derived from a 3D model. There are two aspects of 3D object printing. The first, all the data of the object to be printed in digital format and second, and a machine that reads the digital data and pours in layer after layer of the manufacturing materials to create the final product. Example: you have a tube of toothpaste and you start squeezing it while drawing different shapes. But in real life scenario the deposition of materials to form the final object is controlled by a computer’s 3D images and the digital dimensional data provided by it. A New Approach The current process of manufacturing is a subtracting one and the new technology …

The Recycled Materials for 3D Printers

Despite the increase of materials used and the higher speeds available for 3D printers, there is not much data available on the usable recycling materials. According to a 2017 report by CNBC, nine billion tons of plastic have been produced across the globe since the 1950’s. Approximately nine percent has been recycled. The concern is the additive manufacturing combined with the increased use of 3D printing will fill the landfills. The good news is recycled materials are the most commonly used filament type with the most minimal entry barrier. The optimization of print settings and PLA formulas has made recycled materials the best choice for the average project and creation of home goods for the last several years. The report is attempting to gather more information regarding any other materials. It should be noted PLA is more difficult to recycle because it is a biodegradable thermoplastic. The issue is a closed loop is used to test the sample. This may not provide an accurate representation. The Details of the Process for Recycled Plastics The polymer …

In Short: The 3D Printing Process

3D printing process is not a very complex process. In fact, all the different components and tools have already existed in the current manufacturing sector before. 3D printable models can be created using a CAD software bundle implementing a 3D scanner, or by a plain advanced camera and photogrammetry programming. 3D printed models made with CAD result in lessened mistakes and these can be corrected before printing and fine-tuned before it is ready for implementation. Computer Aided Design for 3D Printing The manual displaying procedure of get ready geometric information for 3D PC illustrations is like plastic expressions, for example, chiseling. 3D checking is a procedure of gathering computerized information on the shape and appearance of a genuine protest, making an advanced model in view of it. Printing Before printing a 3D show from a STL record, it should first be inspected for mistakes. Most CAD applications create mistakes in yield STL files gaps, confronts normal, self-convergences, clamor shells or complex errors. A stage in the STL era known as “repair” fixes such issues in the first model. …

Comparing Open-Source and Low-cost 3D Printers with Commercial Products

When the typewriter was introduced in 1868, it was to people what virtual reality is to us now. It was something people had never seen before, a new idea that added value and made things a little more perfect. The typewriter created perfect typography, but one mistake meant the paper had to be re-written. The same is true today as more and more people learn how to use 3D printing and rapid prototyping. One over-looked mistake in the design of a piece can be fatal to a budget or to the project itself. For that reason, in this article we will discuss the implications and differences between open-source low-cost 3D printers, and commercial rapid prototyping machines. Open-Source Low-Cost 3D Printers Open-Source is the term given to software that is free to use and be edited by people other than the creator. This made a shift in the way that creators and 3D enthusiasts create objects. Imagine if the software was not open-sourced, what would happen? People would have to create and design their own 3D …

Favorite Applications of 3D Printing Technology

A multi-billion dollar industry was born at the turn of the 21st century when the process of 3D printing was introduced in the 1980s. In the past thirty eight years, a lot of changes have been done to the industry, allowing buyercs to purchase their own 3D printers for less than a laptop. It is estimated that by the year 2019 this industry will be worth more than 20 Billion dollars. We estimate it will be worth more if certain industries, like the medical and housing, put these printers to use for mass production. Though there are hundreds of ways in which the 3D printing technologies can be used, we’ve narrowed it down to some of the favorite applications. This article is focused on describing those applications, and is open to interpretation for you to do further research. Favorite Applications These applications are not in order of importance, because they are all fascinating in their own ways. We’ve chosen to discuss food items, innovation and a faster and inexpensive way to prototype, prosthetic components and …

Rapid Prototyping in the Fine Arts, Architecture, Jewelry and Industrial Design

The art that has lived through the centuries, that of Da Vinci, Michelangelo, Picasso, among others, is still loved because of the time it took to make, and the precision of the artists’ hand in creating it. The Sistine Chapel, for example, took four years to paint. The statue of David took three years to sculpt. Now, we can print beautiful and perfect items with the use of rapid prototyping and 3D printing, within hours or days. There’s a company in China that is creating art for a purpose. They are 3D printing houses in twenty four hours. In this article, we will discuss the ways in which rapid prototyping and 3D printing are making it easier for people to delve into the fine arts, architecture, jewelry, and industrial design. Fine Arts Wouldn’t it be amazing if one could eat a course in fine arts and be able to create paintings the same way Van-Gogh or Picasso did? Well, that reality is getting closer and closer. In an article provided by Bloomberg, a 3D printer …

What is the difference between an RP machine and a 3D printer?

In the past decade, we’ve come across some amazing discoveries and inventions in technology, which have allowed our society to create, test, and understand new methods of production. Arguably the biggest break-through has been that of the 3D printer, which had the whole world speaking about it after it was showcased at the annual CES convention. Rapid prototyping has been around for much longer. Used as a way to quickly test a new product or process, it has allowed entrepreneurs to get their ideas out and pivot with speed. 3D printing, however, is a revolution of its own. In this article, we will discuss the differences between rapid prototyping machines (RP Machines) and 3D printing. Rapid Prototyping So what is RP, or “rapid prototyping”? Just like the name implies, it is a method of rapidly creating a prototype of an idea that may work in theory, but may not work as perfect, in reality. In order to know whether or not the idea or product will work, one must create the prototype (preliminary model). Most …

3D Printing Stores and Labs in Berlin

The idea of accessibility is being used in Berlin because it is believed that everyone should have the ability to become a maker and have access to 3D files, 3D printers, and 3D modeling software. Platforms, such as Thingivers; software, such as Meshmixer; and 3D printers are now available for affordable prices. As a matter of fact, there have been a growth spurt in this accessibility over the previous years. Places like universities have this technology available within their facilities, so that students can develop and research in their fields. Recently, the Technical University of Berlin (TU), for instance, has taken it a step further by making the accessibility of additive manufacturing by opening a student run “3D Printing Repair Café”. This past April, the 3D Printing Repair Café celebrated its opening by providing students and even non-students with a space to try out the 3D printing technology. They can do this whether need a creative design model, a spare bicycle part, or just a custom made gift. Also, the space consists of Ultimaker brand …

Functional Parts and Tools by Additive Fabrication – Direct Fabrication and Indirect or Secondary Processes

Additive fabrication is a class of manufacturing procedures where a part is built by adding material layers upon one another. This process has been evolutionary in different manufacturing applications. And as a result, it is now an accepted solution in fabricating customized, geometrically complex, or low volume parts, and it’s recognizable in producing tools and parts that are not possible to combine and form into various materials. Though many applications are hidden from the public and are still in development, their ranges are potentially vast. Even some of the technology’s liabilities are transformed into advantages. Also, additive technology is utilized by directly fabricating items, such as molds and parts, or it is utilized through secondary or indirect purposes. Direct Fabrication Plastic and metal parts are often directly fabricated. With plastic parts, stereolithography, thermoplastic extrusion methods, and laser sintering (LS) are currently the most important forms used in direct fabrication. Stereolithography is a process in creating objects that are three dimensional with using a laser beam controlled by a computer that builds the required structure from …
