Comparison of 3D printing hand board and CNC hand board

What is hand board?

In the process of product design, after we have completed the design drawings, one of the most important things we want to do is to know what kind of things we have designed, whether the appearance is consistent with our design ideas, and whether the structural design is reasonable. In this demand, Beijing Jingke hand model factory came into being.

Generally speaking, the prototype model is a functional sample that is used to check the rationality of appearance or structure according to one or several product prototypes made first according to the product appearance drawings or structural drawings without opening the mold.

The early hand board because of various conditions, mainly in most of its work is done by hand, so the early hand board is mainly "manual hand board". The prototype made in this way has a long construction period and is difficult to strictly meet the size requirements of the appearance and structural drawings. With the development of mechanization, the type of hand board has developed to the CNC hand board: the main workload is completed by CNC machine tools, and according to the different equipment used, it can be divided into laser rapid prototyping hand board (RP, Rapid Prototyping) and machining center (CNC) hand board. CNC hand model has always been very common and popular hand model, can produce computer appliances, digital communications, medical equipment, automotive traffic, intelligent robots and other product categories.

Note: CNC is the Computer numerical control: computer numerical control, referred to as CNC).

CNC machine tools (Numerical Control Machine Tools) refers to the machine tools equipped with computer numerical control system, referred to as CNC machine tools or machining centers.

And at any time the continuous development of technology, is currently very popular a hand model is 3D printing hand model.

What are the differences between 3D printing hand model and CNC hand model? Here we come from the production principle, process and material of the two hand model.

3D printing has advantages that CNC machining centers cannot match.

3D printing hand board and CNC hand board material comparison:

3D printing

1, high material utilization, no waste

2. Real ABS plastic, a variety of colors available

　　CNC

1. The utilization rate is not high, wasting a lot of materials

3D printing hand board and CNC hand board process comparison

3D printing hand board

1. It can process various complex curved surfaces and special-shaped structures

2, one-time molding, after removing the support to obtain a complete sample

3. No need to consider any fixture design

　　CNC

Ordinary three-axis CNC cannot process such complex shapes

2. Complex parts need to be molded many times, and the workload of split programming is large.

3. Need to consider fixture design and manufacture cost structure

Cost structure comparison of 3D printing hand board and CNC hand board

3D printing

1. Bring your own driver software to quickly calculate the printing time and required materials without professional training

2. As long as the size of XYZ molding area is sufficient, multiple parts can be processed at one time without manual duty.

3, WYSIWYG, high precision, no processing errors

4. No complicated maintenance is required, and the material wire of the worktable can be cleaned quickly and simply after printing is completed.

CNC hand board

1, need professional programming personnel, and professional operators and fixture design.

2. Only one part can be processed at one time, and at least three people are invested from design to manufacturing, and the labor cost is high

3. There will be processing errors caused by artificial machine operation errors or poor clamping.

4, the completion of processing requires special personnel to clean the machine tool, clean up waste, etc., and the time is longer (labor cost).

The above is the main distinction between 3D printing hand board and CNC hand board. At present, 3D printing hand board has relatively many advantages and is introduced and used by domestic hand board factories, while CNC hand board is still a common hand board. Beijing Jingke Xingye Science and Technology Development Co., Ltd. specializes in providing all kinds of hand-board model making, including: CNC hand-board model, sheet metal hand-board model, silicone film hand-board model, 3D printing hand-board model and other hand-board model products. Beijing Jingke is committed to providing customers with verification and trial production solutions that shorten the cycle and save costs for the design and development of new products.
