With this new-to-the-world technology, it is now possible to realize complex 3D geometries where DELO’s epoxy material provides stiffness and strength and ACEO®’s silicones provide softness and elasticity – in one print. There is no adhesion between the two materials which means that they can be easily separated after use. This also means that the design needs to provide for mechanical anchoring between the two material segments to ensure part integrity (design guidelines available).
In terms of applications, this opens a whole new world of opportunities where strength and stiffness in combination with elasticity and softness are required. For instance, silicone applications can be made stronger by adding epoxy reinforcements or protective sections, and designers can add functionality by adding tough connector parts.
According to Egbert Klaassen, global marketing director of ACEO®: “The design freedom we offer with our drop-on-demand technology has inspired hundreds of designers and engineers around the world. The possibility to use these complementary materials adds a new dimension and challenges developers to create even smarter designs!”
From the epoxy point of view, engineers can now make hard products safer by designing soft interfaces, they can provide flexibility by adding hinges or dampening by adding spring elements and so on.
According to Dr. Karl Bitzer, Head of Product Management at DELO: “Epoxies are typically used in high durability applications. Enabling 3D printing in combination with silicone elastomers, will open up new opportunities in high performance market segments such as Electronics, Automotive, Machines & Equipment and more.”
Clever combinations not only allow for highly functional designs but can also be more efficient than multiple parts by avoiding complex assembly operations.
