Rapid Prototyping

What Is Rapid Prototyping

Rapid prototyping: commonly known as rapid mockup, fast prototyping and cnc prototyping. The main manufacture processing methods include CNC machining, 3D printing and vacuum casting, all of which are convert 3D data into physical models.

Rapid prototyping occupies a very important part in the entire industrial design system. It is a verification of the appearance, shape and ideal of industrial design, and a verification of the feasibility of structural engineering design. It is an indispensable verification link.

Why Rapid Prototyping

Rapid prototyping is actually to verify whether the design feasibility can reach the ideal state, and what are the hidden drawbacks in the design process, whether it is the disadvantages of modeling or structural design, it needs to be verified by the production of prototype models.

Rapid prototyping are widely used in the design and development stage of new industrial products, and the physical models that are consistent with the design are processed in the shortest time. Designers carry out product confirmation and functional testing, etc., so as to improve the design scheme, reduce development costs, shorten the development cycle, and quickly obtain design approval.

Appearance design evaluation	external dimensions, disassembly ratio, color matching, material and surface texture, etc.
Evaluation of structural design rationality	product size, assembly method, structural strength, matching clearance, material selection, etc.
Product functional test	assembly test, operation test, drop test, electrical test, motherboard performance test, etc.
Cost optimization before production	cost accounting of structural parts (which are necessary and which can be cancelled), optimization of electrical layout (such as FPC wiring, etc.), cost optimization of assembly methods;
Prototype display	market promotion, electronic exhibition display, e-commerce photography, etc.

How Besten Rapid Prototyping Works

Design file output → drawing analysis and quotation → disassembly programming → CNC machining → manual repairing → surface processing → assembly and quality inspection → shipment

What are the design file outputs?

Drawing analysis and quotation

For 3D model files, Besten can receive files in stp/step, x-t, igs and other formats; for prototype process renderings, it is generally CMF files; if the prototype surface has silk screen logo or other pattern requirements, film CDR files are required; If you need to make a structural model, you need to list the materials and production quantities of all single pieces, then the BOM list required; if the structural parts need to be assembled by a prototype factory, or two pieces need to be welded together, and there are special requirements for processing parts, then special requirements are required to make instructions.

A. Receive the design documents and confirm whether the contents of the documents are complete. If there is any discrepancy, communicate with the designer in time.

B. Review whether the design documents are consistent with the 3D production model, and communicate with the designer in time if there is any discrepancy.

C. Analysis of the difficulty of model processing and production, analysis of the feasibility of surface treatment, and timely communication with the designer if there is any problem.

D. According to the difficulty of model processing and production, the production method, evaluate the production cycle, and give the customer a quotation.

Disassembly Programming

CNC Machining

A. The design 3D drawings are processed, classified and disassembled. Some parts that cannot be directly processed need to be disassembled into several pieces and spliced into one.

B. Import the classified 3D files into the programming software MasterCAM to program the CNC machining steps.

C.tool selection, different processing materials use different milling cutters, and the amount of cutting tools for different materials is different.

A. First, fix the solid raw material on the CNC machine. There are many fixing methods, such as double-sided tape, glue, and putty. However, it must be ensured that it is within the processable range, and the raw materials must not be loose.

B. Restart the machine to perform automatic CNC washing and cutting with the programmed 3D file data.

Manual Hand Working &Parts Finish For Rapid Prototyping

A. First, clean the CNC machined parts, and clean up the unnecessary burrs and residues.
B.Check the actual parts and 3D files, if there is any omission, then carry out secondary processing.
C.Manual hand repair, there are processing difficulties on the accessories, and manual repair is carried out if the processing cannot be done.
For example, a small hole that is too deep is not completely opened during the processing process, and it needs to be repaired by hand with tools. Another example is the inner right angle that the tool cannot wash and cut, and the tool needs to be repaired.
D.Sanding smooth the appearance and the special matching surface. Since it is impossible to achieve a completely smooth and smooth effect after CNC machining,tool lines will be left, so it needs to be polished with sandpaper, ranging from 240 to 1200 sandpaper,so as to achieve the desired appearance.

After hand working,we will provid related post finish as per customer file requirements.we can use various post-processing methods to improve the appearance, performance and durability of prototype, providing our customers with one stop style service.for more details about parts finish, welcome to check us more details refere to parts finish.
