At present, the prototype on the market can be roughly divided into several categories: 3D printing prototype, CNC prototype, replica, reverse copying, and so on. But the commonly used ones are still 3D printing hand boards and CNC hand boards for processing. Before popularizing the differences between 3D printing hand boards and CNC hand board processing, let's give a brief introduction.
What is the Beijing prototype prototype? Friends may not know, but the prototype is the first prototype. Simply put, after designing the drawings (3D three-dimensional model diagram, watch it, it is a 3D three-dimensional diagram, not a 2D plane diagram), a sample needs to be made through 3D printing or CNC processing to check the appearance and functional structure, whether the assembly matches, whether the function meets the standards, and whether the parameters meet the requirements, Thus achieving the purpose of avoiding direct mold opening and difficult modification, as well as saving costs.
Why do we need to make a prototype? Because product development or design requires a prototype, creating a prototype is the first step in verifying the feasibility of the product. It is a direct and effective way to detect defects, deficiencies, and drawbacks in the product, thereby improving the defects. 3D printing and CNC hand boards are common methods for making hand board models, so how can we utilize their advantages?
1. Comparison of material utilization rates
3D printing board: high material utilization rate, no waste, and material requirements;
CNC hand board: The material utilization rate is not high and waste, but there are many types of materials that can be processed;
2. Processing comparison
3D printing board: capable of processing various complex surfaces and irregular structures, completed in one go;
CNC hand board: Complex parts need to be processed multiple times, requiring a large amount of disassembly programming workload, and later manual work is also relatively complex;
3. Cost comparison
3D printing board:
(1) Equipped with driver software, fast production, no need for professional training;
(2) Multiple parts can be processed at once, without the need for manual attendance;
(3) The accuracy is not very high, and there are no machining errors;
CNC hand board:
(1) Professional programming personnel and machine operation are required;
(2) Only one part can be processed at a time, resulting in high labor costs;
(3) There may be machine operation errors or poor clamping.
The above is the difference between 3D printing and CNC machining. After understanding the differences between the two, it is also very helpful to choose which machining technology you want to use for your tablet. You can contact us if you have project requirements http://www.vlvpu.com Yo!
