Thermoset Printing

Thermoset polymers are characterized by their inability to be reversibly cured. Once the 2-part liquid resin polymerizes, it cannot revert to the previous state. We currently offer polyurethane grades developed by Chromatic 3D Materials.



Benefits

Thermosets are very rugged materials. Not only are they able to withstand high temperatures, but they are also quite chemical resistant. Since the material ranges in durometer from soft to hard, polyurethanes are great for applications that require flexibility, rigidity, or a combination of the two. The polyurethanes are elastic and return to the original shape after being stretched, if designed to do so.

Applications

• Bladders
• Seals
• Gaskets
• Caps/covers
• Vibration dampeners
• Pulleys/belts
• Handles/grips

Frequently Asked Questions


Can thermosets be 3D printed?

  • Yes, thermosets can be 3D printed. Thermoset materials are being developed predominately in resin form, requiring specific hardware to process the materials.

What are the 3 types of 3D printing?

  • The ASTM International Committee on Additive Manufacturing Technologies recognizes 7 different types of 3D printing. These types are material extrusion, material jetting, binder jetting, sheet lamination, vat photopolymerization, powder bed fusion, and directed energy deposition.

What does thermoplastic mean in 3D printing?

  • Thermoplastic is a category of polymers characterized by its ability to be melted down and extruded more than once. Some examples of thermoplastic that have been developed into a 3D printing grade are nylon, ABS, and PLA to name a few.

What is the strongest material for 3D printing?

  • Advancements in technology allow polymers, metals, composites, and ceramics to be 3D printed – and you would be surprised at how far polymers have come, often times a metal part can be replaced by a printed polymer depending on the application and environment. There are many factors that affect the end strength of a 3D printed part – how the material is stored & prepared for printing, printer technology & quality, print orientation, and slicer settings are equally important as selecting the proper material for the application.

What are the dangers of 3D printing?

  • Like any piece of manufacturing equipment, you should be properly trained and aware of the dangers associated with any 3D printer you will operate. You should be aware of moving parts on the printer, components that heat up and could cause burns, the electrical panel, and material handling & storage instructions. When removing printed parts and post processing them, always handle with care and pay attention to sharp edges and tools that could cause injury. Refer to the material and machine manufacturers guide to ensure proper handling and operation.

How much money does a 3D printer cost?

  • 3D printers are available for beginners, hobbyists, and professionals alike. Depending on the technology, size, and intended market, printer prices can range from a couple hundred dollars to hundreds of thousands of dollars.

What is the difference between thermoset and thermoplastic?

  • Thermosets and thermoplastics are categories of polymers. Thermoplastics can be melted down, formed, and cooled to hardness numerous times (think of how butter behaves). Thermosets can be formed and hardened only once (think of a cake, once it is baked, it can’t go back to batter form).

Is thermosetting better than thermoplastics?

  • Consider your application. Both thermosets and thermoplastics can be quite strong, resistant to certain chemicals, and dimensionally stable. Typically, thermosets have a higher heat tolerance and can be found in a wider range of durometer for applications that require flexibility.

What is an example of a thermoset plastic?

  • Examples of thermoset plastics include polyurethane, epoxy, and silicones.

What is the difference between thermosetting and thermoplastic composites?

  • Thermosetting polymers are irreversibly cured due to crosslinking between the polymer chains. Thermoplastics do not have crosslinks and can be reformed numerous times.

How much does it cost to start 3D printing?

  • Besides the cost of the 3D printer, material, and computer to slice parts and generate the gcode that will run the printer, you will need a variety of tools that vary depending on your printer’s technology. Tools include: material storage, cleaning solution/rags/vacuum, tools to perform work on the printer/install material, spare nozzles, tools to remove the part from the build platform, and tools to post process the part such as pliers, sandpaper, and a utility knife.

What exactly is 3D printing?

  • 3D printing, also know as additive manufacturing, is the process of creating a three-dimensional part by depositing material in the x/y plane and repeating the process along the z axis. The process is laminar, completing one layer before moving on to deposit the subsequent layer.

What can 3D printing be used for?

  • 3D printing can be used across many industries and applications. It may be used in education, prototyping, automotive, aerospace, food, medical, machine shops, consumer products, or electronics to name a few industries. Most often, 3D printing is best suited for low volume parts, custom parts, or highly complex designs.

What is 3D printing and how does it work?

  • 3D printing (additive manufacturing) is the process of joining materials to make a complete three-dimensional part by using model data. The model is ‘sliced’ into numerous layers and those layers are manufactured one by one, on top of the previous. There are different technologies that process materials by different means. The hardware of any given technology is instructed by gcode to ‘draw’ the features of a layer in the x/y plane before the print head offset is adjusted and the next layer is produced. Think of it as stacking multiple two-dimensional drawings until the final model is achieved.
