Learning more about rapid Manufacturing processes

by Albert T.

DDPROTOTYPE is an abbreviation for Decision Dashboard prototype, and it is a company based in China. They specialize in manufacturing certified rapid prototyping and low volumes manufacturing such as vacuum casting, CNC machining, plastic injection molding, 3D printing, and rapid tooling.

DDprototype also works on sheet metal prototype manufacturing, serving automobile, aircraft, office automation equipment, medical equipment, electronic products, optical products, semiconductor products, etc.


In a nutshell, rapid prototyping is the rapid fabrication of a substantial part of a product using a CAD, otherwise known as a 3D Computer-Aided Design (CAD).

To create the intended piece, model, you will have to rely solely on additive manufacturing, commonly called 3D printing. If the design is a described as prototype with high-fidelity, the computer design closely matches the proposed finished product.

How does it work?

The rapid prototype at DDPROTOTYPE includes many technologies, even though many of them apply layered additive manufacturing. These technologies include High-speed machining, casting, and molding are also used for rapid prototyping.

Other conventional processes include;

  • Subtractive – in this process, a pre-existing block material is carved to yield the desired figure using milling, or turning.
  • Compressive –Here, a liquid material is forced to yield into the desired form. Then it will be solidified using techniques such as casting, or molding.

Types of rapid manufacturing?

Here are the different methods that DDPROTOTYPE uses for manufacturing;

1. Laser sintering

This method uses a laser to bring out enough heat. The heat is then used to put materials together. This further creates a 3D model.

2. Deposition modeling

This method creates 3D object using different types of thermoplastic beads. The beads then harden after the extrusion process has taken place. After this process, it becomes super solid.

3. Stereolithography

This issometimes called optical fabrication. This method creates solid objects through several layers of photopolymer resin. As the resin layers are smeared, an ultraviolet beam is aimed to turn it into a solid form.

4. Inkjet printing

The inkjet works by first laying down several powdered material rows and then using a liquid binder to create a solid form.

What are the effects?

Companies like DDPROTOTYPE have fully adopted the use of rapid prototyping in other to deliver better service to their customers. But the question arises, how does the company improve its manufacturing process by using rapid prototyping?

The methods listed in the previous section are time-tested ways that the company can bring out accurate product model, giving the designers and engineers the chance to examine the object thoroughly before carrying out production on a full-scale. You can also decide to evaluate the prototypes for ergonomics and the cost of manufacturing.

It has also made precision testing better, particularly the SLA printing method. The photopolymers in use are as thin as 0.1mm. They can produce parts so accurately that they can test pressure, load and stress tolerance, and aerodynamic performance.

The most profound effect will be that it has also made the production design cycle shorter, i.e., it has reduced the amount of time taken to go from idea to production. A precise prototype can be made in just a few days, and once approved, it can begin mass manufacturing.
