3D printer price-

The differences are as follows:

Accuracy: The most direct difference is the accuracy, which is also the quality that buyers value most. There are very obvious layer lines on the surface of products printed by thousands of machines, while the quality of industrial-grade metal products printed by Germany's EOS M280 is the same as those machine-finished. Of course, the price of the machine is as high as 600W.

Printing principle: FDM (fused deposition) is the earliest 3D printing method invented in the world. It appeared as early as the 1980s. The "scientific name" of 3D printing is actually rapid prototyping manufacturing or additive manufacturing. 3D printing is a term that has become popular in recent years after being promoted by Obama. Currently, the low-end printers (within 10W) ??on the market use the FDM principle. Due to defects in this technology, various problems such as printing accuracy and deformation are caused; the higher-end SLA (light curing molding) uses the lighting characteristics of photosensitive resin and uses ultraviolet light. Such as light source, the molding accuracy is high, but the resin will emit toxic substances during printing, so it is not suitable for home use; the most high-end like SLS (selective laser sintering), which uses laser to solidify the printing material, has the highest accuracy and the most expensive price. Usually in the millions.

Printing materials: FDM fused deposition printing materials are mostly ABS and PLA, SLA photocuring is mostly photosensitive resin, and SLS laser sintering can be nylon, metal, alloy, composite materials, etc.

Companies that sell 3D printers:

US 3D system, stratasys, makerbot

Germany EOS

Print cost:

It mainly depends on what material you use to print, as well as the size of the printed model, filling rate, etc. ABS material is 120-200 yuan/KG

Play with all hands, hope you will adopt it!
