Mastercam 2018 Create Curves Enhancements

By | 2017-05-15T08:44:57+00:00 May 15th, 2017|Categories: Mastercam, Tech Tips|0 Comments

In Mastercam 2018, toggling the CPlane 2D/3D construction mode enables different construction modes for Curve One Edge and Curve All Edges. Setting the construction mode to 2D creates geometry parallel to the current CPlane at a designated Z depth. This eliminates the extra steps that were required to project the 3D geometry to the defined CPlane. Mastercam has added a feature to automatically select tangent solid edges. Holding down the [Shift] key and clicking an edge selects all tangent edges at once. This makes it fast and easy to select small features in complicated parts, without having to repeatedly zoom in and out. Wireframe / Curve All Edges also includes several new features to simplify your workflow. With Face Selection automatically enabled, the [Shift] + [Click] option makes it easy to select all tangent faces with just one click. Curve On All Edges has two new options, which make it easier for you to create tool containment boundaries using curves. Selecting Ignore Shared Edges removes the inside geometry created from the tangent faces, leaving a clean perimeter. In addition, you can remove any geometry inside the outer curves. Choosing Only Outside Loops removes all inner geometry. These powerful features speed your [...]

Simplify Sacrificial Tooling with 3D Printing

By | 2017-05-12T07:56:46+00:00 May 12th, 2017|Categories: 3D Printing / Additive Mfg, Stratasys|0 Comments

The Problem: Complex composite parts with hollow interiors are difficult to manufacture. Complex composite structures, with hollow interiors, present unique manufacturing challenges where internal tooling, generally referred to as a cores or mandrel, is required to define the hollow internal features. Any part configuration that traps the mandrel inside the composite part, requires sacrificial tooling* or a more complex, collapsible or inflatable tool. *Sacrificial tooling – tooling that is only used once and must be broken or washed out. Current sacrificial tooling technology uses materials such as eutectic salts, ceramics, cast urethanes and other similar materials. These options present many challenges, including: Difficulty handling due to fragile material properties Require tooling to produce Limit design freedom due to production or removal methods The Solution: 3D Printing (Additive Manufacturing) Stratasys FDM® technology is capable of producing geometries in dissolvable thermoplastic materials. Although these materials were originally developed to serve as support structures to enable printing highly complex geometries, OEMs and tier suppliers in the automotive and aerospace industries have been utilizing their unique dissolving properties for sacrificial mandrels. In an effort to improve their solution and value to the sacrificial tooling market, Stratasys released a new soluble material dubbed ST130™ along [...]

Nylon 12CF – New 3D Printing Material

By | 2017-05-10T08:41:45+00:00 May 10th, 2017|Categories: 3D Printing / Additive Mfg, Stratasys|0 Comments

There is a new game-changing thermoplastic material for the Stratasys FDM family called Nylon 12CF. The CF is an abbreviation for carbon filled. In this material, chopped carbon fibers are added to a proven FDM Nylon 12 polymer blend resulting in one of the strongest thermoplastics in the FDM material portfolio. Commercial production of carbon fiber began in the early 1960's, resulting from requirements for lighter weight parts and alternatives to metal. Its low thermal expansion, heat resistance, and chemical stability made it a viable solution for aerospace parts as it offered ten-times the strength of steel at one-quarter of the weight. Over the years, the use of carbon fiber branched out into many other industries. It is extremely popular in performance racing, where it is used to create composites that are light and have exceptional fatigue characteristics. For 3D printing, Nylon 12 CF provides the highest flexural strength and highest stiffness-to-weight ratio of any FDM material currently produced and a tensile strength on par with other high-performance FDM materials. Appropriate uses include strong but lightweight tooling, functional prototypes and end-use parts in aerospace, automotive, recreational and industrial applications. In tooling applications, thermoplastics might have the strength but lack the [...]

Reverse Engineering Sheet Metal to a Flat Pattern

By | 2017-05-08T09:31:52+00:00 May 8th, 2017|Categories: 3D Scanning|0 Comments

Today we are going to talk about how to reverse engineer a used sheet metal part back to its original flat pattern. This can be challenging at times, since sheet metal parts tend to bend and distort with normal use. Geomagic Design X can assist you in interrogating the geometry of the part, and reverse engineering it back to the original un-warped shape. After scanning the part, you can import the resulting point cloud into Geomagic Design X and clean up scan file. Next, convert the points to a polygonal mesh, and Auto Segment the mesh. By auto-segmenting the mesh, Design X creates regions made up of polygons that have similar curvature values. Thus, it becomes easy to identify and interrogate geometric shapes. You can then use these regions to create and establish your Datums. At this point, you can start reverse engineering your CAD file by tracing over the mesh profiles, and creating real 2D and 3D geometry. Design X keeps a CAD history tree of everything you’re doing. When you have captured enough information from your polygonal mesh, you can then export your work to your CAD software. In CAD, you can complete your design by converting your [...]

3D Printing to Treat Complex Structural Heart Disease

By | 2017-05-05T08:30:11+00:00 May 5th, 2017|Categories: 3D Printing / Additive Mfg, Stratasys|0 Comments

3D printing is a powerful technology with the potential to significantly change the practice of medicine. In the field of structural heart disease, this rapidly evolving technology can make a powerful impact. Limitations of two-dimensional imaging and added benefits of 3D printing Current conventional cardiac imaging modalities such as echocardiography (EKG), cardiac computed tomography (CT) or magnetic resonance imaging (MRI) primarily utilize two-dimensional (2D) methods that require significant expertise and experience to interpret. In the field of pediatric or congenital cardiology, complex structural heart disease requires precise anatomical delineation before intervention. Consider a heart no larger than a walnut with multiple levels of abnormal connections. Using standard methods of visualization, whether by echo, CT or MRI, the interpreter essentially “reconstructs” a three-dimensional (3D) image from multiple slices or sweeps through this complex heart. By and large, this method works well for the structurally normal heart or for “simple” lesions (1); however, the challenges of interpretation and potential for errors are compounded for heart lesions of moderate or great complexity (1). Three-dimensional methods of visualization such as 3D echo, volume or surface rendering give the added perception of depth, but they are fundamentally limited by 2D displays on which they are [...]
