Many people may not know, many people may not know, the hand is the first board, after the design drawing comes out, 3D printing or CNC processing is needed to make a template to test the appearance and functional structure, so as to avoid mistakes.
Why do we need to make cardboard model? Because product development or design needs to make handboards, making handboards model is the first step to verify the feasibility of products. It is the most direct and effective method to detect product defects, defects and defects so as to improve defects. 3D printing and numerical control hand plate are commonly used hand-made models. So how can we make use of their advantages? We should learn to compare the following points:
Model material comparison:
3D PCB: high material utilization, no waste, high material requirements.
CNC hand board: the utilization rate of materials is not high and the waste is large, but there are many kinds of materials that can be processed.
Comparison of handboard model treatment:
3D printing hand plate: it can process various complex surfaces and special-shaped structures.
CNC hand plate: complex parts need to be processed many times, and programming needs to be separated.
Cost comparison of handboards:
3 D printing tablet:
Equipped with driver software, fast production speed, no need for professional training.
More than one piece at a time, no need for manual processing.
Low precision, no machining error;
Professional programmer and professional aerobics.
Only one part can be processed at a time, with high labor cost.
Mechanical failure or poor clamping.
3D printing and CNC hand samples usually need a small amount of trial production, and it is found that the batch is not enough to improve. Product design can not be perfect, or even can not be used. Once defects are completely abandoned, direct production, a great waste of human and material resources and time. 3D printing and NC processing board are mainly used to manufacture household appliances and digital products. CTS, children's toys, auto parts and other industrial manufacturing fields.
