3d metal printing.
3D printers are coming to the rescue of the industry. No, it is not yet possible to produce equipment in this way.
But here are some, often critical details - yes.
3D printing emerged as a tool for prototyping - the rapid creation of complex models for engineering and design. Initially, plastic was used in 3D printing, and today this technology remains the simplest and most common. An abstract technology is one thing, and a real enterprise with its needs is another.
As these technologies developed and became cheaper, they began to cover other areas and materials. When it comes to important, loaded nodes, ordinary plastic is clearly not enough. Therefore, specialists in the field of additive technologies are working out other methods of 3D printing for industry.
First of all, this is Binder Jetting (BJ) - layer-by-layer application of powder and binder, which allows the use of different materials, including ceramics and metals.

Metal powder for 3D printing POLEMA PR-12X18H10T is a food-grade corrosion-resistant austenitic stainless steel that has found its application in many industries, primarily food, pharmaceutical and chemical. Excellent technical characteristics of steel, making it versatile.
Sometimes the right part has to be ordered months in advance. One can imagine what a headache it is for people involved in maintaining the efficiency of equipment, the chief mechanic, equipment engineer, because everything needs to be foreseen and advance purchase requests for many items, but sometimes equipment can fail suddenly. This may not be the most "hype" type of 3D printing, but it has already found real use in industry.

3D printing can solve the problem: thanks to it, the necessary parts can be obtained almost within a day - and besides, not far from the repair site. A similar production with the usual methods of metal processing - milling, turning, casting, welding - will require a large fleet of equipment and many specialists, in fact, it should be a whole plant and the time can be delayed for a week.
With 3D printing, everything becomes easier: having several printers of different types, you can produce, if not the part itself, then its basis, which will require minimal processing, which can be done in almost any equipped repair site - to avoid unscheduled equipment downtime as much as possible.
As a rule, this method produces no more than a few parts, but they can be made quickly, and for some items it is also cheaper than a purchased counterpart.
If something breaks down every week, you can change the chemical elements, find more resistant materials. For example, such a case: due to the high pressure of the liquid, the same component of a large unit constantly broke down.
Having carefully studied the part, they made it from a more durable material: they carried out mathematical modeling, adding stiffeners, printed it out, tested it - as a result, it became much more reliable. Now it is practically not required to replace it.
I thank the private enterprise "InterTechnoMarket" for the products provided. If you need models for metal printing, you can contact me in a convenient way.
