What material is suitable for making transparent Clear prototypes

Rapid prototyping CNC machining and polishing of PC materials

In rapid prototyping, the common materials used to make transparent prototypes are PC and PMMA (acrylic).
Usually we encounter such a problem: some customers have a habit, if this product uses PC transparent material in future mass production, then they also choose PC transparent material when they ask to make a prototype. That is, the customer will request the same material for prototyping based on the final mass production material.
So what materials are good to use to make transparent prototypes? So is it made according to the customer’s requirements?

At this time, we should explain the pros and cons with customers, the texture of PC material is relatively hard, in the later polishing and polishing process, if you want to make the product transparent as mass production goods is very difficult. Customize quick parts here for you to explain in detail. Therefore, when making transparent prototypes, it is better to choose PC transparent materials but acrylic materials, and I will explain them in detail below.

From the perspective of polishing and polishing, the PC prototype takes a long time, because its material is relatively hard, and some narrow places can not be polished by hand at all, even if it is convenient to polish, it takes longer than the acrylic prototype. On the contrary, it is much more convenient to use a softer acrylic material to make a transparent prototype.

In terms of color, PC material is not completely transparent, if you look closely at the prototype made of PC material, you will find that its surface is purple or yellowish, if you want to make it completely transparent, you need to soak in the potion for a period of time (this is a chemical reaction); The acrylic material is completely transparent, so the acrylic prototype is already transparent when polished, and there is no need to do any treatment. There is a sentence that vividly explains the difference between PC prototype and acrylic prototype, that is, “the transparency of the PC prototype is smoked, and the transparency of the acrylic prototype is ground out”.

After reading my explanation, I believe you know more about transparent prototypes, and you can choose the right material when making transparent prototypes in the future.
