3D print beholder

On the other hand, we have a wide "yellow" range, conditionally fit for printing, which everyone uses - this is obviously an abnormal mode that they try to compensate through Linear Advance or the flow settings in the slicer.

I strongly do not recommend touching the flow setting in the slicer without a clear understanding of how it works.

These properties alone make ABS a "difficult to print" and "terrible smelling" plastic.

But what about the 0.6 mm nozzle?

As we can see, the 0.6 mm nozzle handles ABS easily and naturally over the entire temperature range and in a larger speed range.

Compare this with the PLA result on the 0.6 nozzle from the previous experiment.

It is obvious that ABS has a lower maximum print speed from the "green" range than PLA, as well as the conditionally allowable speed from the "yellow range".

However, ABS completely lacks the minimum allowed print speed, at which plastic flows out of the nozzle uncontrollably, and it can be printed on both an all-steel thermal barrier and a barrier with a Teflon tube.

As in the previous test, the 0.6 mm nozzle performed well, which cannot be said for the 0.4 mm nozzle.

And that's all for me, I wish you a good print, and constructive criticism for yourself in the comments.

Despite the continued air of mystery and exoticism, 3D printing is becoming a reality in our lives. As experts predict, the development of this technology, together with unmanned vehicles, will be among the most destructive in terms of its impact on many industries, reducing the need for blue-collar jobs. Indeed, the development of technology can give rise to the problem of "extra people" being forced out by robotic production. The Da Vinci Institute estimates that more than 2 billion “traditional” jobs will disappear by 2030.

Gartner estimates that the 3D printer market grew nearly 50% in 2013 to $412 million, of which $325 million was in the enterprise segment. As analysts are sure, the demand for 3D printers will grow along with the growth of the quality and performance of devices. By 2015 sales will double. The 3D printer market is at a turning point. Although the market is still in its infancy and advertising exaggerates the capabilities of the technology, the speed of development and the rise in user interest are pushing hardware manufacturers and software developers to improve the quality and ease of use of printers. As 3D printing technology improves, it will be used more and more in product development and manufacturing.

Garbage housing

Industrial 3D printing of houses has begun in Shanghai. Thus, the government hopes to reduce the cost of building buildings. It is important to note the high speed of construction: a small house is being built in a day.

The giant 3D printer can work around the clock without an observer. The material is a mortar of cement and recycled construction waste. House of 200 sq. m costs about 5 thousand dollars. However, a printer that needs factory conditions to work is not mobile, and transporting a finished house to the right place will cost more.

Despite the common name, the term "3D printing" covers nine different technologies that differ in the techniques and materials used. The four most common are stereolithography, photopolymerization, extrusion (Fused Deposition Modeling, FDM) and sintering (Selective Laser Sintering, SLS). Depending on the printing method, the device can be either monochrome or color. At the CES-2014 exhibition held at the beginning of the year, there were several dozen booths of companies producing 3D printers. The best known are 3D Systems, Stratasys, Makerbot, and Solid Concepts, each operating in a different hardware segment.

The 3D printing market is currently in chaos - the players are diverse, the technologies are extremely immature, and they are sorely lacking in standardization. Experts pin great hopes on market consolidation: sooner or later IT giants should pay attention to this industry. At a minimum, we can expect interest from related industries - manufacturers of PLM systems, in which digital product layouts will be designed, and players in the traditional printing market.

For example, HP is working in this direction. The company recently announced that they have overcome two major problems with 3D printing - slow print speeds and poor surface quality. At the same time, HP's plans are primarily aimed at the corporate market. As for ordinary consumers, it is possible that a 3D printing service will be created for them, accepting tasks and issuing finished products.

Autodesk also announced its entry into the 3D printing market a month ago with the launch of two products: Spark, an open 3D printing software platform, and its own 3D printer capable of working with a wide range of materials. Documentation on them will be available to everyone for further development and experiments.

New Features

The advent of affordable 3D printers could completely change the balance of power in many industries. The reason is simple: 3D printing has the potential to undermine the economies of scale that are central to modern industry and drive mass production. As a result, a kind of “renaissance era” may come in the manufacturing sector, because even small companies will be able to produce high-quality products without the need to build factories.

Major changes in logistics are also likely. Now the cost of shipping goods from places of production is a significant part of their value. In the case of 3D printing, the production of many goods will become mobile and it will be reasonable to move it closer to consumers.

“In recent years, the world has seen a significant breakthrough in understanding the role of 3D printing and related technologies from a business point of view,” said Frederic Vacher, director of strategic media marketing at Dassault Systemes. 3D printers are already being used extensively in the production of automobiles, consumer goods, and parts for aircraft and rockets to physically evaluate the parameters of objects being created before mass production begins. The foundation laid in recent years and the significant price reductions have resulted in an ever-wider range of 3D printing machines.

What is important, devices not only fall in price, but also acquire new features every year. For example, machines capable of printing titanium, aluminum and silver parts have revolutionized several industries. The creators of jewelry got the opportunity to develop products that are unique in shape, which could not be realized using traditional technologies. It became possible to show people in advance how this or that fruit of a design fantasy will look like, significantly reducing the risk of disappointment from the final product. Examples of 3D printing of buildings are already known.

Concept car - per year

So far, the use of 3D printing in industry has mostly been limited to printing prototypes in the development of new products. This seriously reduces the cost and speeds up the development and testing of products. Businesses quickly release physical samples of a product or print smaller copies for research or presentation to customers. The Bleu project, carried out by Dassault Systemes throughout 2013, is indicative. The main goal of the project is to create your own concept car from scratch to showcase the latest 3D modeling technologies. An important role was played by the use of an accurate 3D printer for multi-composite printing Stratasys Objet260 Connex.

The work was carried out by a team of a designer, two modellers, two visualization experts, two surface modelers and one mechanical modeller. At the first stage, miniature five-centimeter models were created. They were designed to identify the main design flaws. At the second stage, 3D models 10 cm long were already used to study and work out the proportions of the car. The printed models made sure that in terms of volumetric perception and proportions, all design elements are balanced and fit together.

The third stage of the project, which is extremely important in the automotive and aerospace industries, is the production of an aerodynamic model. This model must be tested in a wind tunnel. The model of the car has already grown to 26 centimeters, it has new details - mirrors and bumpers. At the final stage of the project, a fully functional model of the concept car was printed.

To print structural elements (tires, chassis, windows) on a 3D printer, several types of materials were used.

Special mention should be made of new opportunities for the spare parts market. Many companies are required to provide their customers with spare parts for many years. The fulfillment of such obligations requires significant expenses for the storage of "dead" stocks. 3D printing technologies allow you to print parts on order and store only their digital models. Thus, suppliers have at their disposal a warehouse of virtual spare parts that are invisibly present and available at any time.

One of the industries that are developing rapidly in Russia is construction. Despite common misconceptions, it is very receptive to new technologies, including 3D design and printing.

“Yes, with the development of 3D printing, the world will change beyond recognition, including the labor market. Some professions that do not require qualifications in the first place may disappear, while others, on the contrary, may appear,” admits Anastasia Morozova, Head of Architecture and Construction at Autodesk in Russia and the CIS.

According to Morozova, the development of 3D printing in construction will give rise to at least four new professions:

• BIM-manager - a specialist in building information modeling (Building Information Modeling). The demand for such specialists is already huge. In fact, such specialists appear at the intersection of two professions: a designer and a CAD manager - a system administrator responsible for technical support for the work of designers.

• Engineer of integrated digital control of construction - a specialist who works with a 3D model of an object directly at a construction site.

• Specialist in virtual reality. Modern 3D technologies make it possible to "visit" the object already at the design stage. In the future, stereo rooms may be created for this, where a client will be shown a virtual object using augmented reality technologies.

• Own 3D printer operator.

The advent of 3D printing technologies can be considered inevitable - it's only a matter of time. In any case, it makes sense for CIOs of manufacturing companies to prepare the ground in advance. 3D printing will be based on PLM and 3D modeling technologies. It is on them that you should pay special attention.
