Dymax1While your design project centers around creativity and innovation, for the 3D printer using resin, it’s all about the chemistry in the materials–and coming from Dymax Oligomers & Coatings, that means we’re talking Bomar oligomers. These products achieve faster 3D printing with power lasers, higher quality, and greater satisfaction all around for the manufacturer.

Composed of relatively few molecules (as compared to polymers, which, as the poly- prefix would indicate, offer many molecules), Bomar oligomers present the best outcome for 3D printing with SLA, DLP, and even 3D inkjet printers. Variations in the chemistry offer flexibility for the designer in 3D printing and once they understand how the materials work, the designer can manipulate oligomers to their own devices in terms of mechanical properties. And if one material doesn’t work for them, Dymax will customize oligomers in line with customer requirements.

flexibleWhile the oligomers may be limited in molecular structure, that certainly doesn’t mean they impose limits in 3D printing with resin–and in fact, it’s quite the opposite. If you are looking for more choice in viscosity as well as being able to manipulate flow, Dymax oligomers offer you options, as well as eliminating object deformation.

In addition to the mechanical properties these oligomers provide, they are non-yellowing for higher optical clarity and offer color stability for better looking objects. You will find that your 3D prints provide a tack-free surface adding quality to moving parts, and are also easier to paint and finish.

“The company’s products are perfectly matched to work seamlessly with each other, providing design engineers with tools to dramatically improve manufacturing efficiency and reduce costs,” Corinne Rebillard, Marketing Products Specialist of Dymax, told 3DPrint.com.

mainOligomers such as BR-345 allow for better aesthetics, reduced distortion in prints, and better impact resistance. BR-144 offers outstanding qualities such as hydrolytic stability, high gloss, and causes little irritation to skin. With an oligomer like BR-741, adhesion is improved, abrasion resistance is improved, and weatherability develops.

Dymax offers post-curing equipment, which may be necessary for 3D prints and especially if rework is necessary for your 3D model. With the UV Light-Curing Flood System and the BlueWave 200 3.0 Spot Lamp System, it’s easy to both cure multiple 3D assemblies and provide application flexibility.

While 3D printing may be a newer technology, thus just being coupled with Bomar oligomers, the specialized materials company, on the receiving end of many accolades throughout recent years, was founded over 20 years ago with their oligomers being used in a variety of worldwide applications for energy curing.

Dymax scientists and researchers make a wide selection of the materials for “emerging application technologies,” and because of their strength in acrylate and urethane chemistry, they are the experts to go to for superior product development. Typical markets that they cater to are in areas like aerospace and automotive, electronics, industrial, medical, and more.
