Speedo Takes Lead in Swim Gear Design with Multi-material 3D Printing

By | 2017-01-04T08:18:46+00:00 January 4th, 2017|Categories: 3D Printing / Additive Mfg, Stratasys|0 Comments

Using a Stratasys 3D Printer for design verification during the product development cycle means that many more design iterations are feasible, weeding out mistakes and creating better-designed products. Top swimming gear brand Speedo has used its Stratasys Objet350 Connex 3D Printer for over half a decade. Famous for both kitting out top swimmers and its supremely secret product development process, Speedo gave Stratasys UK reseller SYS Systems a small glimpse inside. The product development arm of Speedo is focused at their research and development center, Aqualab, in Nottingham, England. They use their Stratasys PolyJet-based 3D printer to prototype and validate designs prior to production for vital equipment like goggles or other “hard goods,” such as training aids and swim caps. Early and accurate design validation not only reduces the design cycle but also screens out design flaws prior to production. Prior to having a 3D printer in-house, the product development cycle could take weeks or months and relied on a maximum of two hand-tooled samples before going into large-scale production. Changes made after the production tooling was created were prohibitively expensive. Now, designs can be 3D printed, in multiple materials when necessary, in a day or less and [...]

Stratasys Full-Color 3D Printing Helps TV Ad Air On Time

By | 2016-12-15T14:30:52+00:00 December 7th, 2016|Categories: 3D Printing / Additive Mfg, Stratasys|0 Comments

For ‘Dave,’ the main character in the storyline, more than 800 different facial expressions were 3D printed with the Stratasys full-color J750 3D Printer. An eagerly awaited holiday tradition is the British supermarket chain Sainsbury’s Christmas TV ad. Drawing on hot trends in both popular culture and technology, this year’s spot is proving to be a winner. Shot entirely in stop-frame animation, the Sainsbury’s ad is a touching and funny mini-musical called “The Greatest Gift.” Composed by Bret McKenzie, half of the comedic musical group Flight of the Conchords, and sung by British actor-talk show host James Corden, the ad features a number of different engaging characters. The characters’ faces, which required hundreds of variations to make the three-and-a-half minute film, were 3D printed on the Stratasys J750 3D Printer by 3D Print Bureau and Tri-Tech. The short film was directed by Sam Fell and centers on the character of Dave, who discovers a way to spend more time with his family at Christmas. According to Richard Pickersgill, workshop supervisor at puppet makers Mackinnon & Saunders, the elaborate production needed a technology capable of delivering fine detail and rich, high quality color, but within a strict timeframe. “As [...]

Vapor Smoothing for 3D Printed Parts

By | 2016-12-15T14:30:52+00:00 December 2nd, 2016|Categories: 3D Printing / Additive Mfg, Stratasys|0 Comments

Vapor smoothing can be used to produce a polished, consistent finish on your 3D parts. In conventional injection molding for mass production, parts come directly off the mold with a mirrored or textured finish. No post processing is required and upon cooling, the part can be packaged and shipped to its destination. Molders achieve this complete finish using polishing techniques with brushes, felts, stones, and other tools. With fused deposition modeling, heated thermoplastics are extruded layer-by-layer to form a 3D part. Material can be extruded at incredibly thin layer thicknesses, ranging from 13 thousandths of an inch all the way to 5 thousandths. However, FDM still produces visible layer lines that can affect the cosmetic appearance. And while ultra-thin layers produce a better appearance, the thinner the layer, the longer it takes to print. Fortunately, vapor smoothing allows you to effectively smooth 3D printed parts directly after they come off the machine. Through vapor smoothing, parts are dipped into a vapor tank containing a liquid that is brought to boiling point. The vapor rises and melts away the part surface, eliminating all layer lines. The process only takes a few seconds and your left with a smooth shiny part. Vapor [...]

What’s in your toolbox? For Cyclone Racing, an automotive racing team from Iowa State University (ISU), it’s 3D printing. These students are discovering the benefits of additive manufacturing while having fun competing in the famous Society of Automotive Engineers (SAE) International Formula car competition. In the Formula SAE competition, students are instructed to design, build and then test their open-wheel racecar, which will then be raced against other collegiate teams. Students 3D printed the intake assembly with the throttle cable directly on top of it. ISU student competitors are pushing the limits of collegiate racing by making the manufacturing process a whole lot simpler. This year it means that the Iowa team created their best Cyclone yet – the CR-21 – using design for 3D printing. A Stratasys Fortus 450mc 3D Printer with ULTEM1010 3D printing material was chosen; ULTEM1010 especially for its thermal and chemical properties and superior strength. So, what did students consider before 3D printing? What will the complexity of the car be? What will the optimal weight be? What types of force will act upon it? With these criteria taken into consideration, the students decided to 3D print three components for the Cyclone racer: [...]
