I decided to briefly go over the descriptive part of the Atlas 3D printer from the American manufacturer Titan Robotics, which on the Russian market has so far only echoes from English-speaking members of the forum and several videos on the Russian segment of Instagram. BUT!

The Atlas 3D printer has a screw principle of material feeding. Is this a good solution for Atlas? Let's figure it out.
Screw
Recently I came across an article on the Internet called "The Best Extruders for 3D Printers", which described various systems for feeding and melting ROD. Guys, what if we throw away the rod and print directly from granulate! Yes, yes. It is possible! As the guys from Colossus this principle works, and works very well! Not only does the raw material become cheaper, since there is no intermediate stage of material processing, but you can also vary the characteristics of the material by “playing with compounds”. However, if this has already been done and there are successful and ready-made solutions on the market, then what is the special thing here? And the thing is, gentlemen, that this 3D printer has a combined system. That is, if you want to print from barthreads, or from granules. Whether this is good or bad is another question, one can only say one thing for sure - a good solution for those who have accumulated a large number of 3D printers with traditional feed in their production barthreads, where it is clearly impossible to escape from suppliers of extruded raw materials. A certain good solution for the "transition period" from threads to screws.
dimensions

So. What kind of camera should a 3D printer have that prints from granules? Where can you use fiber additives that allow you to print at high speed and without shrinkage? Probably from 3 meters on the side? That's right, but Atlas has a maximum printable area of 106cm x 106cm x 121cm.
That is, nothing new.
Performance

It prints very quickly with special compounds, but the speed of printing with traditional materials (ABS, PLA, PET-G) is limited by the physical and mechanical processes of 3D printing in the atmosphere.
That is, nothing new.
Materials

Flexible: TPE / TPU
Standard: PLA / ABS / PC
High Performance: Glass or Carbon Fiber Filled 20-50% ABS / PC / PA / PPO / PEI / PPSU / PEEK / PEKK
That is, nothing new.
Intermediate withdrawal
In fact, another manufacturer of 3D printers, which conceptually is no different from competitors in the issue of 3D printing with granules. The presence of a screw, and, as a consequence, the ability to provide a choice, thread or granulate, allows the manufacturer to raise the level of 3D printing both its own and the client's and use the machine as a transitional option to a huge industrial machine for industrial 3D printing. But so far from another manufacturer, since the Titan Robotics park does not yet have a worthy "successor" to the "screw" family. Whether this is temporary or not, time will tell. The company has serious ambitions. Follow the news.
