1.Price variance

Industrial grade 3D printers have high technical content, and most of them are excluded from the competition threshold such as patents. At present, they still belong to the seller's market. SLA, SLS, SLM, 3DP, inkjet and other ordinary equipment generally range from 600000 to 10million yuan. If you want to choose a suitable and cost-effective printer according to your specific needs when purchasing a printer.
Desktop level 3D printers are basically available for several thousand yuan at the current price. Of course, with the development of 3D printing technology, there are also some industrial 3D printers with high cost performance, such as G12 and G5 launched by piocreat.

2.Printing speed
Due to the cost limitation of desktop level 3D printers, 16 bit and 32-bit chips are mostly used as the main control chips, so the data processing speed is difficult to compare with 64 bit CPU, and there is little difference in FDM due to accuracy.
In SLA technology, the scanning speed of desktop level 3D printer is mostly 1m/ s, while that of industrial level 3D printer can reach 7m-15m / s, so the speed of industrial level 3D printer is much faster than that of desktop level 3D printer. Piocreat G5 and G12 use granular consumables, which can match print nozzles of different sizes, and the printing speed is much faster than FDM.

3.Design and removal quality of printing support
Whether there is 3D printing support and the design of separable parameter printing of printing entities is an important symbol to distinguish between industrial computers and desktop computers, because industrial 3D printers are applied in the actual production field, and the effect of post printing should have high controllability requirements.
Friends who have used desktop level 3D printers know that whether FDM or SLA devices, because the support and entity are not distinguished in the printing process, the stripping of the support after printing is a very uncontrollable factor, which often leads to stripping failure and damage to the entity.

4.Print accuracy
At present, there are only FDM and SLA technologies for desktop level 3D printers. From the data point of view, there is no great difference between industrial level 3D printers and desktop level 3D printers. The small resolution of FDM is determined by the size of the print extrusion port, which is basically between 0.3-0.6mm, and the layer thickness is determined by the Z axis. Because desktop level 3D printers use stepping motors, industrial level 3D printers use servo motors, and 3D printers print high-resolution products, Basically, it is between 0.05mm and 0.2mm. Higher accuracy and more realistic printing.

5.Reliability of printing
Generally speaking, the reliability of printing is the success rate of printing. The success rate of printing is the indicator that really tests the skill of the design team, and it is also an important indicator to distinguish desktop level and industrial level 3D printers.
Industrial grade 3D printers are used for mass production, and the printing success rate can be almost 100%, which greatly improves the production efficiency, reduces the comprehensive costs including manpower, time, etc., and can print finished products in batches, and it is 0 scrap, so it is much better than desktop 3D printing.

The success rate of desktop 3D printer is only more than 70%. This also means that for a hundred times of printing, at least 30 of the materials used are discarded for various reasons, and the users of these materials can't be recycled and can only throw them away. Therefore, every time the printing fails, it is a time-consuming, money consuming and infuriating thing. For users, reliability is not an objective indicator after all, and it is difficult to quantify itself.

6.Print size
Generally speaking, the larger the print size supported by 3D printers, the more expensive the printer will be. If you need a 3D printer that can print the size of a microwave oven, I'm afraid the price should be at least $3000. At present, most desktop 3D printers on the market can only print small things. Even if you want to print objects the size of the bottom of the iPad, I'm afraid many printers are not competent. But if you only need to print objects the size of a tea cup, almost all printers on the market can do it.

7.Application fields.
Industrial 3D printer machines are widely used in aviation, aerospace, automobile manufacturing, mold, jewelry manufacturing and other industries. Buyers are mostly concentrated in large enterprises, manufacturing subcontractors and modeling manufacturers, while the desktop 3D printer market is more concentrated in education, makers, and the production of simple models. Customers are mainly large, medium and primary schools, makers, and creative individuals.
