1 LASER SINTERING (LS) 3D PRINTING & ADVANCED MANUFACTURING

2 MANUFACTURING GAME CHANGER Go beyond conventional techniques to access a new level of production freedom using engineering thermoplastics. Additive manufacturing has completely changed the way we design aircraft. [Laser Sintering] has allowed us to design and build mechanisms and structures we wouldn t be able to make with any other manufacturing method. Dr. Nicholas Alley, Area-I CEO PRODUCTION CAPABILITIES Laser Sintering production parts are strong, water and air-tight, heat resistant and made out of a range of materials, including neat nylon 11s and 12s or nylons with fillers such as glass and aramid or carbon fibers (to enhance physical properties). Depending on part feature thickness, 100% density can be achieved with material properties comparable to those found with traditional manufacturing methods. ENGINEERING-GRADE MATERIALS LS provides a full range of engineeringgrade thermoplastics well-suited for high requirement applications. PEKK CF HT23, a high performance alternative to aluminum, provides ultimate thermoplastic capabilities at a fraction of the weight. Standard plastics are available for prototyping and are well suited to bring new products to market quickly and economically. 2 StratasysDirect.com

3 LASER SINTERING Laser Sintering (LS) also called Selective Laser Sintering creates tough and geometrically intricate components using a high-powered CO 2 laser to melt powdered thermoplastics. One key advantage of LS is that as a part is made, it remains encased in unsintered powder. This eliminates the need for support structures and allows for complex geometries. While Laser Sintering began as a way to build prototypes early in the design cycle, it is now used for batch and serial manufacturing in a wide variety of applications. Common LS uses include connector housings, ductwork, fuel tanks, control surfaces, wiring harnesses, brackets and manufacturing tools. Stratasys Direct Manufacturing continues to take Laser Sintering to the next level by implementing proprietary process controls to ensure consistent handling and recycling of materials along with machine maintenance. When you select an engineering material, it is because you have specific requirements for use. These engineering LS materials are for high performance and have repeatable build quality. Our quality control systems provide material traceability, mechanical property verification, process specifications and stringent quality controls to ensure the parts we deliver meet your stringent specifications. LS BENEFITS Freedom of Design is fully realized with LS. Unlike conventional methods that restrict the design process, LS gives you the freedom to design for function rather than manufacturability. Single unitized structures, weight reduction, and freeflowing, complex designs are all achievable with LS. Part Consolidation is an exceptional attribute realized by many LS applications, particularly within the aerospace industry. With the ability to produce complex features, undercuts and internal features with ease, LS can consolidate what once was a multiple component assembly, resulting in labor savings and reduced part count. Manufacturing Control for parts that are durable, heat and chemical resistant result from utilizing the LS process. LS has proven to be an affordable means to build durable, stable production parts in low quantities or for high volumes when the designs are too complex for traditional manufacturing. With decades of combined engineering and production manufacturing experience, Stratasys Direct Manufacturing leverages that expertise to become an extension of your team, revolutionizing the way you think about production.

6 LASER SINTERING PROCESS The LS process begins with a design in the form of 3D CAD data. The 3D CAD object is sliced into 2D cross-sections using automated software. The cross-sections are scanned and melted via a CO 2 laser. Each new layer is melted to the preceding layer. Completed parts are removed from the powder material and the unsintered powder is recycled. 01 Part Build Chamber 02 Dispenser Platform 03 Powder Bed 04 CO 2 Laser 05 Scanning Mirror 06 Plastic Powder 07 Leveling Roller 08 Unsintered Powder Collector UNITED STATES: VALENCIA, CA SAN DIEGO, CA TUCSON, AZ PHOENIX, AZ BELTON, TX AUSTIN, TX EDEN PRAIRIE, MN DETROIT, MI BRAZIL: SÃO PAULO, BRAZIL P / E info@stratasysdirect.com STRATASYSDIRECT.COM 2017 Stratasys Direct, Inc.
