Formlabs Announces Two New Materials

Formlabs’ library of versatile, reliable Engineering Resins is formulated to help product designers and manufacturers reduce costs, iterate faster, and bring better experiences to market. They recently announced the addition of two new materials for the Form 2: Grey Pro Resin for Versatile Prototyping and Rigid Resin. Grey Pro Resin offers high precision, moderate elongation, and low creep. This material is great for concept modeling and functional prototyping, especially for parts that will be handled repeatedly. This material is best for form and fit testing; prototyping injection molded products; mold masters for plastics, silicones, and more; jigs and fixtures for manufacturing. Rigid Resin is filled with glass to offer very high stiffness and a polished finish. This material is highly resistant to deformation over time and is great for printing thin walls and features. Rigid Resin has the highest modulus of all Formlabs materials. It has great impact strength, heat resistance, and stability, but is more brittle than Tough and Durable. This material is best for turbines and fan blades; jigs, fixtures, and tooling; manifolds; electrical casings and automotive housings.

3D Printing Conceptual Models with Formlabs

By | 2017-12-29T08:41:52+00:00 December 1st, 2017|3D Printing / Additive Mfg, FormLabs|0 Comments

3D printing conceptual models is a great way to save time and money early on in the development stage. Engineers can use printers as a sketch pad to build and test out various iterations, and determine necessary adjustments to improve the design. Functional parts take prototyping to the next level, allowing engineers to test models for form and fit and to see how they perform in an assembly. Depending on the application, it is sometimes necessary to combine multiple parts using screws or some other form of fastening. Formlabs has collected various design options for screw threads that can be used with their Tough engineering resin. In the white paper download below, you can learn about all of the options, see the pros and cons of each method, and determine the best fit for your application.

Behind the Design of the World’s Largest Lens

Reprint from  Today, the world’s largest lens is located in a lighthouse on Oahu, Hawaii. The Fresnel lens at Makapu’u Point, 12 feet tall, 8 feet wide, and painstakingly crafted out of glass, has held the title since 1893. This coming Valentine’s Day, the title will transition to a new lens: a 10-by-12-foot Fresnel lens made of interlocking 3D printed bricks. The installation, Window to the Heart, is a collaboration between Formlabs head of design Marcelo Coelho and design studio Aranda\Lasch, and is the winner of the 2018 Times Square Valentine Heart Design Competition. Previous winners include The Office for Creative Research, Collective-LOK, Stereotank, Young Projects, and Situ Studio. Window to the Heart is designed and 3D printed specifically to distort and capture the image of Times Square, optically bending light—and attention—to a heart-shaped window at its center. Visitors can look through the window or photograph themselves within it, completing the loop between the lens of the eye and the lens of the camera. A Lens that Reflects Culture “Marcelo and I walked around Times Square and noticed that everyone has their camera out, photographing themselves in the light of the media around them. In this sense, Times Square is a symbol for how we experience our world,” Aranda said. “It is a physical manifestation of our culture, one dispersed and absorbed through cameras and screens.” “The lens is what makes it all possible so we decided to design our own at the scale Times Square demands,” Coelho said. Window to the Heart places the world’s largest lens in one of the world’s most Instagrammed places: the center of Times Square. Coelho and Aranda\Lasch chose a Fresnel lens design for the installation. Originally developed for lighthouses, Fresnel lenses are made of a set of concentric annular sections, enabling a large aperture and short focal length without the mass and volume required by a conventional lens design. Window to the Heart’s Fresnel design is a diffusing lens, rather than a focusing lens like that of a lighthouse or magnifying glass. Instead of projecting light, it captures it. The installation is segmented into concentric rings that flatten a large spherical curvature while retaining its optical effect. Each individual lens is uniquely designed to act as both a brick and optical element. 3D Printing a 12-Foot Lens Lens making has traditionally involved tedious labor and precision, requiring a series of steps of casting, cutting, and repeatedly polishing glass. “Previously, a lens of this scale would have been impossible to create,” Coelho said. “Window to the Heart serves as an example of what’s possible with the latest advances in design, materials, and fabrication.” The lens is composed of 98 concentric rings, and each circle is made of a series of bricks 3D printed with Formlabs’ Clear Resin, which is capable of the resolution and clarity that optical elements require. The entire sculpture is composed of 1,090 bricks. Once printed, the individual bricks require cleaning and post-curing, but do not require the [...]
