Traditional design approaches don’t make the most of new manufacturing methods, like additive manufacturing, which are removing design constraints and opening up new possibilities. The optimal shape of a part is often organic and counterintuitive, so designing it requires a different approach.
Topology optimization lets you specify where supports and loads are located on a volume of material and lets the software find the best shape.
Kick off the year by learning about one of the most exciting advancements in modern design and manufacturing. Join experts from PADT and nTopology for an interactive roundtable discussion on the ins and outs of topological optimization.

Engineering simulation has traditionally been used for new product design and virtual testing, eliminating the need to build multiple prototypes prior to product launch.
Now, with the emergence of the Industrial Internet of Things (IIoT), simulation is expanding into operations. The IIoT enables engineers to communicate with sensors and actuators on an operating product to capture data and monitor operating parameters. The result is a digital twin of the physical product or process that can be used to monitor real-time prescriptive analytics and test predictive maintenance to optimize asset performance.
Join PADT’s Senior Analyst & Lead Software Developer Matt Sutton for an in depth look at how digital twins created using ANSYS simulation tools optimize the operation of devices or systems, save money by reducing unplanned downtime and enable engineers to test solutions virtually before doing physical repairs.
This webinar will include an overview of technical capabilities, packaging for licensing, and updates made with the release of ANSYS 2019 R1.

Have you ever wondered about choosing a plain versus funky infill-style for filament 3D-printing? Amongst the ten standard types (no, the cat infill design is not one of them), some give you high strength, some greatly decrease material use or printing time, and others are purposely tailored with an end-use in mind.
Highly detailed Insight slicing software from Stratasys gives you the widest range of possibilities; the basic versions are also accessible from GrabCAD Print, the direct-CAD-import, cloud-connected slicing software that offers an easy approach for all levels of 3D print users.
A part that is mimicking or replacing a metal design would do best when built with Solid infill to give it weight and heft, while a visual-concept model printed as five different test-versions may work fine with a Sparse infill, saving time and material. Here at PADT we printed a number of sample cubes with open ends to demonstrate a variety of the choices in action. Check out these hints for evaluating each one, and see the chart at the end comparing build-time, weight and consumed material.
Infill choices for 3D printed parts, offered with Stratasys’ GrabCAD Print software. (Image courtesy PADT Inc.)
Basic Infill Patterns
Solid (also called Alternating Raster) This is the default pattern, where each layer has straight fill-lines touching each other, and the layer direction alternates by 90 degrees. This infill uses the most material but offers the highest density; use it when structural integrity and super-low porosity are most important.
Solid (Alternating Raster)
Sparse Raster lines for Sparse infill also run in one direction per layer, alternating by layer, but are widely spaced (the default spacing is 0.080 inches/2 mm). In Insight, or using the Advanced FDM settings in GrabCAD, you can change the width of both the lines and the spaces.
Sparse Double Dense As you can imagine, Sparse Double Dense achieves twice the density of regular Sparse: it deposits in two directions per layer, creating an open grid-pattern that stacks up throughout the part.
Sparse High Density Just to give you one more quick-click option, this pattern effectively sits between Sparse Double Dense and Solid. It lays rasters in a single direction per layer, but not as closely spaced as for Solid.
Hexagram The effect of this pattern looks similar to a honeycomb but it’s formed differently. Each layer gets three sets of raster lines crossing at different angles, forming perfectly aligned columns of hexagons and triangles. Hexagram is time-efficient to build, lightweight and strong in all directions.

Advanced Infill Patterns (via Custom Groups in Insight)
Hexagon By laying down rows of zig-zag lines that alternately bond to each other and bend away, Hexagon produces a classic honeycomb structure (every two rows creates one row of honeycomb). The pattern repeats layer by layer so all vertical channels line up perfectly. The amount of build material used is just about one-third that of Solid but strength is quite good.
Hexagon
Permeable Triangle A layer-by-layer shifting pattern of triangles and straight lines creates a strong infill that builds as quickly as Sparse, but is extremely permeable. It is used for printing sacrificial tooling material (i.e., Stratsys ST130) that will be wrapped with composite material and later dissolved away.
Permeable Triangle
Permeable Tubular This infill is formed by a 16-layer repeating pattern deposited first as eight varying wavy layers aligned to the X axis and then the same eight layers aligned to the Y axis. The resulting structure is a series of vertical cylinders enhanced with strong cross-bars, creating air-flow channels highly suited to tooling used on vacuum work-holding tables.
Permeable Tubular 0.2 Spacing
Permeable Tubular 0.5 Spacing
Gyroid (so cool we printed it twice) The Gyroid pattern belongs to a class of mathematically minimal surfaces, providing infill strength similar to that of a hexagon, but using less material. Since different raster spacings have quite an effect, we printed it first with the default spacing of 0.2 inches and then widened that to 0.5 inches. Print time and material use dropped dramatically.
Gyroid 0.2 Spacing
Gyroid 0.5 Spacing
Schwarz D (Diamond) This alternate style of minimal surface builds in sets of seven different layers along the X-axis, ranging from straight lines to near-sawtooth waves, then flipping to repeat the same seven layers along the Y-axis. The Schwarz D infill balances strength, density and porosity. As with the Gyroid, differences in raster spacing have a big influence on the material use and build-time.
