Rapid prototyping with First Part
Prototype is at the important position in the entire product process. The requirements or functional information before prototyping are relatively abstract. The process of prototyping is the process of converting abstract information into concrete information. First Part specialize in the production of high-quality, low-cost prototypes. Rapid prototyping can shorten the time to develop prototypes and produce high-quality physical models through 3D design ideas. Rapid prototyping can be used to test designs and materials, reducing the risk of advancing product production without sufficient information. In the first part, we can make prototypes through CNC machining, 3D Printing, Sheet Metal Fabrication, and Urethane Casting.

CNC Machining


Plactic Injection Molding
The process essentially involves the injection of molten plastic material (resin) under high pressure into the cavity of a metal die before cooling the mold to solidify the shape into its final part. Depending on the part size, material, and design complexity, the injection molding cycle may span anywhere from a few seconds to a couple of minutes.
3D Printing
3D printing, also referred to as Additive Manufacturing (AM), constructs a part from a CAD model or digital file by bonding a layer unto a preceding layer of melted material till the final form of the part is attained. Our high level of repeatability makes our 3D printing service can development journey and accelerate from design to production part in as quick as 1 day.

How to make a prototype
At First Part, our unique CNC precision machining capabilities allows you to take advantage of speed, precision, size, cost and even volume. With over 25 engineering-grade materials to choose from, we deliver CNC machining services that allows you to machine parts in your desired material without compromising on cost, functionality and speed. With CNC machining you can meet a wide range of your product development needs. Here are the major benefits of precision CNC machining:
1. Clear Prototype Goal
The first step in making a prototype is to clarify the goal. Clarify the goal and function of the product. Only when you have a clear goal can you focus on make it right.
2. Prototyping
Engineers use CAD to turn the prototype concept into a 3D rendering. A 3D rendering lets you visualize it from all angles. Helping you see approximately how a physical version of your prototype will look.
3. Build a Prototype
Once you have a virtual prototype. Determine the materials, technology, process. We are ready to build a physical prototype.
Typically, early working prototypes are built of less expensive materials than later versions to save money while fixing design flaws.
