Topics Top 3D Expo: 3D printing in auto-tuning, Artyom Solomnikov, Imprint
In anticipation of the upcoming Top 3D Expo exhibition and conference , which will be held on April 19 in Technopolis Moscow, we talk about the conference participants.
Before you will speak Krasnoyarsk entrepreneur, CEO of Imprint Artem Solomnikov.
A graduate of the Polytechnic Institute of Siberian Federal University, Artyom Solomnikov is one of the first people in Krasnoyarsk to engage in the commercial use of 3D printing. At first it was a custom-made print and episodic sale of equipment and consumables, which he worked with his wife, but wanted something more. And the opportunity presented itself - in 2013, Ewald Lepp came to the company, who was already trying to design and assemble 3D printers - another engineer, and at the same time a designer, and it was decided to create his own 3D printer. A year later, the first Siberian 3D Hercules printer was assembled.
The theme of the speech by Artyom Solomnikov: "The real history of modern auto-tuning - Generative design and 3D printing."
The speaker will talk about the use of Hercules 3D printers for printing parts for tuning and customizing cars.
Founded in 2013, IMPRINTA has been providing 3D printing services. The idea of creating your own 3D printers just came up.
In February 2014, the development of our own 3D printer began, which was tasked with meeting the expectations of the buyer, being easy to use and reliable. The assembly of the first prototypes began in March, and the first finished instance was released after five months of development.
By the end of 2014, the first dozen Hercules were sold. Then they looked like this:
In 2015, the first enlarged Hercules was created - Hercules Strong, which took into account the problems of the first printers and significantly expanded the working volume.
In 2016, a smaller version of the Strong was introduced, incorporating its improvements in mechanics and a new design, but in a compact case, the updated Hercules. In the same year, enhanced quality control was introduced .
To improve the quality of Hercules cases, in 2017, we launched our own powder coating and metalworking workshop, our own production of carriages, guides, nozzles and other parts. Also in 2017, Hercules Strong and its design were updated. The printer received the Brand of the Year Award at 3D Print EXPO.
2018 is another update, the new Hercules is released, with low noise and improved print quality.

3D printing of hunting trophies
Nikolai Vorobyov - sculptor and founder of the VoronFab workshop.
The workshop is engaged in the creation of various voluminous objects, including interior decorations in the form of hunting trophies. Printed in a workshop on a Hercules single-extruder 3D printer.
“ Since I originally went to the idea of my own production from digital sculpture, I did not see an alternative to 3D printing. More precisely - the very possibility of 3D printing has become an incentive - it’s very cool to hold in your hands your model, which I had only seen on the monitor before. ”
All models print differently, for example, a wolf printed with supports, ears down. It was possible to print it without supports, but in this position the layers will be visible on the eyebrows, therefore they should be located in a different plane.
Some models are printed compound, divided along the axis of symmetry. On the cut, they have fixing inserts and nests for them.
They print mainly PLA, since it almost does not shrink and does not require a thermostatic camera for high-quality printing.
Smoothness of the models is achieved by reducing the height of the layer, which greatly stretches the printing time, or post-processing. It is irrational to print large parts with a small layer thickness, it takes several hours, so they undergo post-processing.
PLA is very poorly polished mechanically, but dichloromethane can be used for chemical polishing. Baths and immersion of the model in solvent in the workshop are not used, they use brushes made of hard bristles.
“Hercules was my first printer, so there was nothing to compare. Actually, I studied 3D printing on it, and for sure at first I did something wrong, I was mistaken. A worthy result was not obtained immediately. So, when choosing a printer, technical support and the ability to just get the printer out of the box and start experimenting without having to assemble the designers were very desirable. So the choice fell on Hercules for this reason, plus the cost at that time from ready-made printers he had a suitable one.
Now, after a while, having gained experience in printing and talking with the printer, I will probably note its reliability. Having inserted the bar and sent the file for printing, I can be sure that the work will be completed. I do not remember the case that the printer did not finish, interrupted printing. Printing time was up to 24 hours. ”
3D printing for dentistry
Nikolai Zakharov is the founder of the Phantom Lab orthodontic studio, where they make eliners and surgical navigation templates.
Navigation templates allow you to carry out dental operations with great accuracy, directing the drill drill or surgeon's scalpel exactly as planned.
Eliners are used to align the bite - a gradual change in the location of the teeth in the jaw. They are made according to a digital model, which is obtained by direct 3D scanning of the teeth or, as here, by scanning the casts taken from the patient. The model obtained by scanning is changed by the doctor in such a way as to fulfill his function (the location of the teeth on it changes very short distances - each pair of eliners moves them no more than a quarter of a millimeter), and then is printed on a 3D printer and used to create the eliners.
“For the production of each elevator, we print a separate model of the jaw on a Hercules 3D printer.
Then we take a transparent dental plate made of special hypoallergenic materials, heat it and press it with a vacuum to the 3D-printed model of the jaw, to which it fits snugly. Everything, the tray is ready, it remains to cut and process. In essence, this is thermoplasticization: vacuum thermoplasticizing molding. ”
3D printing for cinema
Nikita is a cameraman in a video studio who, in his spare time, is keen on what he earns - shoots videos.
To get a beautiful picture, Nikita needed an anamorphic lens - such lenses are used when shooting movies, they stretch the image vertically and contract horizontally, which is then corrected at the installation but leaves beautiful visual effects such as horizontally elongated glare and distortion at the edges of the frame.
Anamorphic lenses are professional equipment that costs a lot of money and is not suitable for budget cameras. To obtain the desired effect, you can buy a special lens, at a cost approaching 20 Hercules 3D printers, or a lens nozzle, costing one Hercules. But all this is not necessary if you have Hercules.
Nikita found a decommissioned film projector with the necessary lenses, created lens holders in 3D modeling software, printed them on Hercules and assembled the attachment for shooting himself.
It took no more than an hour to draw, 10 hours and 100 grams of plastic to print. The cost of plastic and electricity is negligible compared to the price of purchased analogues of such a nozzle. In addition, there is no need to wait for delivery from abroad.
“Anamorphic nozzles cost from $ 1000, so you understand how much I saved by making this nozzle with my own hands. Now I shoot with her help cinematography.
In general, I often print various fasteners and plugs on Hercules. This helps me especially when something is not available in the store. And all this trifle is lost very quickly. ”
Video materials that will be shot at the upcoming exhibition of the Top 3D Expo 2019 conference will be available only to business and VIP ticket holders.
