Exoskeleton is a free plug-in for creating meshes. It is currently comprised of two components: Exo Wireframe and Cytoskeleton.
- Exo Wireframe thickens line/node into watertight meshes. It solves the nodes using a convex hull and stitches the hulls together with polygonal struts.
- Cytoskeleton thickens the edge network of any existing mesh into a thickened mesh. The topology of the base mesh enables the production of a clean quad meshes whose vertices are all of even valence. Because It uses the half-edge mesh library developed by Daniel Piker and Will Pearson, it also requires the installation of the Plankton dll’s and gha.
Exoskeleton remains a work in progress, and as bugs are fixed and new components and features introduced, updates will be placed here. Furthermore, Exoskeleton is an open-source library.
Intralattice is a plugin for Grasshopper used to generate solid lattice structures within a design space. It was developed as an extensible, open-source alternative to current commercial solutions. As an ongoing project developed at McGill’s Additive Design & Manufacturing Laboratory (ADML), it has been a valuable research tool, serving as a platform for breakthroughs in multi-scale design and optimization. By giving you full access to the source, we hope to collectively explore lattice design at a deeper level, and consequently, engineer better products.
The rise of additive manufacturing (i.e. 3D printing) has allowed engineers to integrate new orders of complexity into their designs. In that regard, this software generates lattice structures as a means to:
– Reduce volume/weight while maintaining structural integrity.
– Increase surface area as a means of maximizing heat transfer.
– Generate porosity in bone scaffolds and implants
– Serve as a platform for structural optimization.
In doing so, it should always output a watertight mesh suited for 3D printing.
Meshify is a cloud-based design service, which converts a user uploaded solid CAD file into a 3D printable mesh-like lattice structure. You can download 3D-printer sliced files (or STLs) and request print quotes from online print providers through 3YOURMIND.
The intuitive web interface allows you to customize the lattice structure by adjusting parameters, such as rod thickness and rod length. You can also choose whether to mesh the volume or just the surface. The lattice structure can be combined with solid regions to create complex composite parts. For full design freedom, you can even upload your own lattice definition (see description here).
nTopology was founded with one goal: To help engineers make better 3D printed parts. Our software offers a fluid transition from mechanical design to DFM, and allows for both explicit and computer assisted creation of highly complex lattices structures.
With nTopology, you can quickly design parts that are stronger, lighter, and easier to manufacture than ever before.
In my discussions with prospects and customers for DigiFabster the issue of “complexity” of models comes up regularly. However, due to the fact that we have been planning and executing a data entry overhaul for almost a year, we never really had a chance to focus on the issue.
Now the a.m. overhaul is in beta, things will run their course, and I had some time to analyze and synthesize my interview notes on the subject. The problem my interlocutors described was the following:
Most of the time, the volume of a model says very little about the resources in machine time, work and material that will be spent on it.
This has to do with a thing that for lack of a better word I have been calling “complexity”.
Why is complexity so important that it keeps popping up in conversations? Easy: We are in a business which competes with other manufacturing techniques, and which wins out only if the objects to be created are very hard or even impossible to make with traditional tools and traditional methods.
3D Printing – The New Drive In Automotive Manufacturing
The global automotive industry sector is set back by its own internal competition. While a third of the industry revenue is accounted by the largest OEMs, a stiff competition lies among the manufacturers of automobile accessories and parts. Additive manufacturing technology brings to the industry areas to ponder about, which might turn out to become a potential game changer soon.
Here are some points that show how 3D printing is indeed the next revolution to the automotive industry:
#1 – Innovation of Flexible Design
Unlike traditional manufacturing methods, 3D printing produces components with fewer restrictions when it comes to design. The enormous flexibility allows manufacturers the freedom to include customized features and new l3functionalities such as complex geometries, electrical wiring through hollowed structures, printed parts made of multiple materials, and lightweight lattice structures, which are lighter, safer and faster.
