Getting the right resin for any FDM 3D Printing Project is the main deal-breaker between getting the job done or getting a useless prototype. Learning about these resins will make your workshop much more effective. It's also pretty helpful to have some basic knowledge about the technologies available to handle your manufacturing project. The most widely available techs to handle FDM 3D Printing are CLIP and Polyjet. This what each one of them can do:

PolyJet Printing – Works just like an inkjet printer; it delivers one layer on the prototype at a time in a tray. UV rays are used to consolidate the prototype. All the data must be fed manually to the software before getting started; the hardware will do the rest. Although it is a cheaper technology and was first developed to create FDM 3D Printed prototypes, it is not exactly well regarded for its durability.

CLIP Printing – The name is short for Continuous Liquid Interface Solution. A more recent development allows us to use digital projection using a permeable oxygen window to take liquid resins while UV lights get it solid. The amount of data required before getting started it's minimal as long as you have a CAM or CAD model in place. The technology aides the creation of 3D-oriented prototypes easier, but it also takes a little more time to get the finished product consolidated if we use multiple layers.

The Resins of Choice for These Technologies

Acrylate

This liquid resin can achieve the sturdiness of PVC with a solid printer, it's probably the most expensive material on the list, but it's also the one that offers the better results. It's the way to go for intricate designs and durable products. It's the material of choice for digital sculptors.

Methacrylate

The strongest resins on the list and one that is also incredibly multifunctional. It works on both types of printers, and it's the best material to create mechanical props or designs with hollow parts. The finished products always deliver a clean finish with little to no after-work required to trim edges or make the surface smoother.

Verowhite

The best material to work with Polyjet printers and the one most suitable for working with products with a single color scheme. It's amazing for mid-level details and clean finishes. It also offers a good range of sturdiness. It's commonly used in the medical industry to design customized prototypes.

There are many more resins out there, but these are the basics to get started, ether if you are an enthusiast or looking to get some knowledge about FDM 3D printers. Keep in mind that the size of the filaments delivered by these varies depending on the project, so you need to do some heavy homework if your intent is to create a product from scratch.
