Comparison of CNC machining and SLA machining process

in terms of cost, since the SLA technical cost is mainly related to the component of the part, about parts such as high precision, thin wall or hollow structure, SLA cost is better than CNC; On the heavy parts with relatively simple structure, the cost of CNC is dominant, CNC comparison is suitable for manufacturing various solid parts with relatively simple structure and heavy contrast, and SLA technology is mainly suitable for various messy structures, or parts with high construction requirements.

CNC machining features:

1. The demand is programmed according to the part data, and the parts with messy structure are split and processed according to the demand, and then bonded and assembled after processing;

2. Demand planning and use of fixtures during processing. Regarding the split parts of large specifications and messy structures, in order to ensure the splicing accuracy, special inspection tools should also be considered;

3. The material can be processed directly by using a variety of materials such as ABS, acrylic, PP and even metal. The mechanical function of the material induction is higher than the SLA skill.

SLA processing (3D printing) Features:

1. The skill is flexible and can end the part manufacturing of a very messy structure at one time, and its manufacturing cost and manufacturing speed have nothing to do with the messy degree of the part;

2. The manufacturing speed is fast, and the parallel processing of several parts can be made together within the processing specification of the equipment. From the data to the end of the part, it takes only a few hours to a dozen hours to end;

3. CAD/CAM is seamlessly connected. CAD data can be processed and manufactured directly on the computer without data programming and parts splitting;

4. In the process of parts processing, there is no need to consider the planning and application of the inspection fixture;

5. The mechanical resistance of the resin materials used is slightly poor, and the ABS class can be reached, but it cannot fully meet the function of the real material.

don't believe in a low-cost prototype

If you select a prototype factory online, I have seen a lot of low prices on average with ordinary prototypes, but don't believe it. Because the prototype factory with low price is not very high on the quality of the prototype, the requirements for the material are not very strict. There are only two possibilities for low prices. One is that poor materials are used, and the other is that the quality is not high! So choose the prototype factory on the Internet, the first manufacturer to rely on-- Tuowei model, a prototype manufacturer with more than ten years of experience, has been working hard to build the first brand in the prototype industry to ensure!
