The rapid prototyping industry is expanding and growing very fast. Also, there are many new types of advanced technologies all the time. 3D printers also called polyjet 3D printing services is one of the newest types of 3D printers. These printers are made by a company called Objet situated in Israel.
Let's Know About the Basic Operation of Polyjet 3D Printers
3D printing polyjet works by building up models one layer at a time which is called additive manufacturing. A moving set of heads sprays out fine droplets of photopolymer liquid at the right positions in every layer. Also, these droplets are then hardened almost quickly by an ultraviolet lamp, and this results in a model with high precision and correctness.
Materials
There are many different types of materials that can be used with polyjet 3D printers. Verowhitefullcure 830 is one of the most popular ones. This is a rigid and opaque white material that is as strong as common plastic. Other colours like opaque and transparent provided as rubber-like materials using the name tango.
Let's Know About the Strength
It includes fine details, smooth surfaces and quick printing that can be sanded and painted very easily. Such amazing characteristics let the models be used for form, fit as well as light functional testing. Also, small moveable features are possible like wheels and gears that is something that other processes can't do as well. Remember, a polyjet model that is painted looks amazing and is useful for making presentations. These models can be used in many different other Applications like mould making, vacuum forming and so on.
What are the Weaknesses?
Its low-temperature resistance is one of the biggest weaknesses. If the temperature exceeds 130 degrees, then the model starts wrapping. It makes it a poor candidate for outdoor and automotive usage. But, indoor usage with light to medium loads placed on it must work fine.
What is the Pricing?
The price of polyjet 3d printers varies greatly and depends on which firm does the printing. So, it can cost more or less than stereolithography models. You can buy small models right from rapid prototyping houses for a price of $15 or even less but larger models can be in the hundreds of dollars. You must shop around by getting various quotes from different The Best Polyjet 3d Printing Services to find the lowest price. Ensure to check the lead times needed by these companies as well.
