ASA(Acrylonitrile Styrene Acrylate) is an all-purpose thermoplastic 3D printing material used to produce prototypes, manufacturing tools and finished goods.
Owners of Stratasys 3D Production Systems in the UAV industry can now benefit from ASA's UV stability, strength and durability, as the company has introduced the new material to be used with its Fortus 360mc, Fortus 400mc and Fortus 900mc.
Stratasys Ltd. (Nasdaq:SSYS), headquartered in Minneapolis, Minnesota and Rehovot, Israel, is a leading global provider of 3D printing and additive manufacturing solutions. The company's patented FDM®, PolyJet™, and WDM™ 3D Printing technologies produce prototypes and manufactured goods directly from 3D CAD files or other 3D content.
Systems include 3D printers for idea development, prototyping and direct digital manufacturing. Stratasys subsidiaries include MakerBot and Solidscape, and the company operates a digital-manufacturing service, comprising RedEye, Harvest Technologies and Solid Concepts. Stratasys has more than 2500 employees, holds over 600 granted or pending additive manufacturing patents globally, and has received more than 25 awards for its technology and leadership.
Engineers at MIT Lincoln Laboratory (Cambridge, MA) 3D printed (FDM technology on a Fortus 400mc) a UAV with telescoping wings made of Ultem 9085.
Structure was primarily FDM except for a carbon fiber backbone that all the parts were attached to. Designed to be highly modular, the aircraft was essentially 3 reconfigurable pieces: the fuselage pod on the front with the avionics and batteries, the wings, and the empennage.
To adjust the CG for different payloads all the parts can be moved around. The wings are printed without support material (an option only available with Fortus 3D Production Systems) with an internal structure that made them pretty strong (see above video).

The video above includes a flight demonstration of a UAV that was manufactured using StratasysFortus 400mc Production Systems. Typical applications of this vehicle include use by police departments, fire departments, and other emergency first responders, as well as military applications. According to company CEO Bill Davidson, when the company bought their first Stratasys3D Printer, they thought that it was an impressive technology – but they didn’t really understand all that it could do.
While they originally figured they would use it to produce little prototypes or giveaways for their customers, FDM-based (Fused Deposition Modeling) 3D printing has now “crept” into every aspect of their manufacturing process. In particular, they found that the ULTEM™ 9085 resin material is particularly well-suited to aviation applications.
As flame retardant high performance material, ULTEM exhibits a high strength-to-weight ratio and FST (flame, smoke, and toxicity) rating which make it an excellent choice for the commercial transportation industry – especially aerospace, marine and ground vehicles. The FDM-based manufacturing process allows UAV Solutions to very rapidly make changes to the avionic structures, thereby enabling them to meet the high performance and precise demands of their customers. In fact, Davidson states that using the ULTEM 9085 allows them to manufacture components that could not be made with standard milling procedures.
Stratasys Ltd. (NASDAQ: SSYS), a leading manufacturer of 3D printers and production systems for prototyping and manufacturing, has announced that remote control systems manufacturer, Survey Copter, is successfully using its 3D printing technology to produce prototype and short-run component parts for mini-unmanned aerial vehicle (UAV) systems, also known as drones.
France-based Survey Copter, a subsidiary of the European Aeronautic Defence and Space Company N.V. (EADS), specializes in the design, production and integration of complete remote systems for surveillance photography and video service applications for UAVs and other airborne craft, as well as for sea and overland vehicles.
Having previously outsourced its prototyping requirements, Survey Copter turned to Stratasys for an in-house solution that could reduce costs and ensure greater efficiency and autonomy, granting the company the means to rapidly produce very small quantities within 24 hours. Via Stratasys' French distributor, CADvision, Survey Copter subsequently installed two 3D printing solutions - a Stratasys Dimension Elite 3D Printer and Stratasys Fortus 400mc 3D Production System, which offers nine production-grade engineering thermoplastics using Stratasys' patented Fused Deposition Modeling (FDM) technology.
"Effectively meeting our 3D printing needs can only be achieved via machines that are capable of producing quality parts with high reliability,"explains Jean Marc Masenelli, managing director, Survey Copter."Stratasys' reputation for delivering 3D printers that meet these criteria head-on made them the logical company to partner with."
Spearheading Survey Copter's prototyping and short-run manufacturing activities, the Stratasys Fortus 400mc and Dimension Elite 3D Printers are deployed in the production of component parts for the company's mini-UAV systems, including both helicopter and fixed-wing variants weighing up to 30kg and 10kg respectively. Ranging from a few millimetres up to parts measuring 40cm x 10cm, these components comprise mechanical structures for optical turrets, structural elements of aircraft, battery compartment housing, supporting structure, as well as scale models.
High Performance Materials Engineered for Aerospace
For Masenelli, the ability to utilise different materials according to specific application needs offers key advantages for producing durable 3D printed parts. Such materials include FDM thermoplastics polycarbonate, ABS and high performance ULTEM 9085 which boasts superior strength and lightweight properties, as well as other desirable characteristics including FST (flame, smoke and toxicity) rating. This safety standard, particularly valued within the aerospace and transportation industries, ensures a material won't promote a fire, release harmful smoke, or emit toxic fumes.
"That we are able to print production-grade materials such as high-performance FDM thermoplastics like ULTEM, which is qualified for aerospace applications, is a definite plus for our operations," he explains.
"The Stratasys 3D Printer can produce parts with complex shapes - for us a highly sought after requirement and a principle differentiator that sets Stratasys' proposition apart from that of other providers," he adds. "This specific capability enables us to produce parts of wide-ranging dimensions and hollow forms, as well as full honeycomb structures."
Featuring two material bays for maximum uninterrupted production, the Stratasys Fortus 400mc 3D Production System produces accurate, durable, repeatable 3D parts with superior throughput. It is available in two configurations: the basic system which builds parts as large as 355 x 254 x 254 mm, and an optionally upgraded system which builds parts as large as 406 x 355 x 406 mm. With four layer thicknesses to choose from, users can fine-tune their desired balance between FDM's finest possible feature detail and the fastest build.
The Stratasys Dimension Elite 3D Printer features the finest resolution of any Stratasys Design Series Performance 3D Printers and produces nine colors of real ABSplus thermoplastic. When the finest dimension resolution of 0.178 mm is not required, the Dimension Elite allows users to accelerate printing with a layer thickness of 0.33 mm.
Stratasys/CADvision will be exhibiting at the forthcoming Paris Air Show (17th - 23rd June, Paris, France) on stand 3-E54.
