Significant events and trends
In the 3D printing market, new technologies, materials are constantly appearing, new devices are being announced. Some of them from time to time set the next bar for competitors, rather than unusual areas
applications can motivate developers to accelerate refinement of existing technologies. Our speakers have shared the most significant 3D printing market events in their last couple of years
Alexander Kornweitz (Color World) rightly notes that the year is not over. In particular, the world’s largest 3D printing event – FormNext’s Exhibition – took place in late November
Frankfurt. It was there that the latest novelties were presented. At the same time, Mr. Kornweitz celebrates the release of Nike and New Balance sneakers with 3D-printed soles
(It is believed that their quality is significantly higher than traditional).
Illya Vinogradov (3D Vizhn) most interested in the release of new equipment on already known technologies. For example, an application for a Formlabs industrial machine, startup is enough
budget for the standards of 3D Systems FIGURE 4, as well as the development of new segments by Stratasys (one of the leaders in the field of industrial equipment) in the direction of SLA- and SLS-technologies.
According to Vasily Kiselyov (Top 3D Group), 3D technology allows you to digitize the foot and release an individual insole at a very affordable price. It should be noted that this direction is not so much
is actively covered in the media, despite the fact that thousands of people around the world feel uncomfortable walking.
In addition, 3D printing is widely used in the production of racing cars, including for Formula 1: this technology allows to produce lighter details that are not inferior in reliability
traditional counterparts. “Our company is assisting the Bauman Moscow State Technical University. The guys build their own cars to participate in the international Formula Student races, almost all the details in them
unique, so do not do without additive technology. In particular, the engineers of Top 3D Group helped to produce the wings for their race car, – says Mr. Kiselev. – Another new one
the direction of activity of our company – collaborative work. However, in the process of solving individual customer integration problems, it became clear that there are no customized robots for these robots
nozzles, such as gripping sponges, fingers, fasteners. With 3D printing capabilities, these problems are easily solved, but a machine would need to be made earlier. ”
Among the interesting new items Ashchen Hovsepyan (SIU System) notes the hybrid model of 3D printer manufactured by 3D Ceram, which allows printing with ceramics and metal. In addition, since 2019
SIU System in Russia is a model NEXA (DLP technology), whose capabilities ensure the rapid release of products of any geometry. For example, depending on the size of the part and the volume
ordering the manufacturing time will take a few minutes, and the production of the whole product will take 6 seconds, explains Ms. Ovsepyan.
Ivan Zakharchev (3DTool) believes that the most significant event in the world can be called the new generation of devices from Formlabs, as well as a significant development of 3D construction. At that
At the same time, in Russia, Picaso3D introduced Designer XL and announced its two-extruder version, while Imprinta updated the entire line of technology and released a two-extruder Hercules Strong Duo. IN
Mr. Zakharchev is convinced that both solutions are a completely new technological base, and this is obviously a new bar for competitors. Among the materials, the line of Rec3D X line confidently declared itself:
A great example was the already launched ABS-based FormaX composite filament. “But the year is not over yet, in the fall and winter, as a rule, the most noticeable news”, –
agrees with his colleagues, Mr Zakharchev.
What obstacles impede the development of the segment?
The scale of additive manufacturing is still extremely small. According to some estimates, this is only 0.02% of the world production of all types of products. What hinders development?
Alexander Kornweitz (Color World) offers a clearer comparison of the 3D printing market with a table tennis ball. He is convinced that in the foreseeable future no
significant changes in this ratio will not occur primarily because of the slow speed of the 3D printing process itself.
Ilya Vinogradov (3D Vizhn) notes that at the moment, the main task of additive manufacturing is not to produce large volumes, but to produce small series of parts in
as prototypes for functional testing. It is important to understand that the task is not to replace already established rules, but to reduce the time to market a new product and minimize the risk
errors. “In this respect, SLM technology is most in demand as a final product, but again in the context of either the inability or the high cost of producing parts in standard ways, or
optimization of the mass parameters of the part, ”said Mr. Vinogradov. The fact is that industrial equipment and materials are still quite expensive. If you compare the prices of materials for 3D printing
the most popular types of ABS and PA and their foundry counterparts, then the latter will be ten times cheaper. In addition, the production speed of the large batch casting method is much higher, and yes
the surface quality of such parts is better.
Vasily Kiselyov (Top 3D Group) states that even traditional industries today it is difficult to afford to buy a full solution (will require $ 1 million and above), and more budgetary
options are not always able to meet the needs of those interested in 3D printing companies.
Ashchen Hovsepyan (SIU System) notes that the process of expanding additive manufacturing in Russia is being delayed by a lack of materials and a poor understanding of the capabilities of these technologies. see
industrial equipment at work, touch metal or ceramic printed parts, compare the traditional method of casting with the method of using forms printed on a 3D printer, and
Wax smelter models – that’s what drives manufacturers to use additive technologies, she says.
Ivan Zakharchev (3DTool) Recalls that the goal of additive manufacturing at this stage of formation – to complement and expand the capabilities of classic production models. That is why
Leading machine tool manufacturers are teaming up with 3D printer manufacturers to create comprehensive solutions. As an example it is enough to mention the LASSIM project – complex
devices that allow you to simultaneously print a metal product and finish it using a multi-axis milling machine. “To name the specific reasons for the lack of displacement, then
this is not yet the physics of the process, the need for postprocessing even for SLS and photopolymer technologies, long printing time, ”said Mr. Zakharchev. At the same time some tasks
only 3D printing can solve it, which is why it is so actively implemented, for example, in aviation.
