    A closed-loop, continuous honeycomb FFF toolpath, graded to any field, and arbitrarily remapped while exactly preserving weld offsets. All with out-of-the-box . Who has an application or wants to pull some coupons?

    Any reason why you prefer the tree on the right, ?

    In design for layout, into illustrator, SVG out. Into Fusion. Extrude. Export as .SAT into nTop. Fanny about. Screenshot. Back to Indesign. For the ridiculous reason of making a fancy graphic for the next issue

    In case you were wondering what that fancy simulation-driven diamond surface part was for. I'd be ashamed if I weren't laughing so hard. And will prolly get stuck in the glue. But the diagonals were within tape measure tolerance, which is a first, and thus no diagonal clamp.

    FDM/FFF DFAM tip: Sharp vertical corners ring your gantry like hitting it with a hammer. Consider C2+ rounds on such edges to provide a nice smooth gaussian instead of a sharp impulse. Also: simulation driven variable density diamond surfaces in .

    Have been thrilled with some early success modeling and printing soluble supports with . Congrats to and team.

    Finally got in control of maintaining the size of critical repeating features while varying others through an arbitrary transform. This pattern uses conformal maps on the complex plane vary density around point features. Weld distance is preserved.

    Adventures in consumer 3D printing continue. Finally found a soluable support that I can get PETG (from ) to stick to after failing with PVA. Aquatek BVOH from works great with the exact same settings as the PETG. Printing on Pro2 w/ 0.4mm nozzles.

    Here's a nifty benefit of the field driven approach - blending intersection points on complex geometry sets - the Boolean union field has an option for blends or chamfers - then auto-applies them. Can be applied to so much more than just lattice/part junctions

    Low velocity coolant enters from one side (blue) into a reinforced plenum, flowing into medium velocity passages that stabilize the pressure at the high velocity conformal layer (purple). The flow then exits from the symmetric (red) passages and plenum on the other side.

    This conformally cooled cavity concept integrates a heat exchanger to stabilize temperature at the surface. Other than a cavity on the side you'd normally see a core, what do you think?

    Spending some time, post- deadline, learning more about - good way to learn these types of tools is to pick apart samples and adapt to new test projects. This one is focused on adding ribs to the exterior of a part but has been adapted to remove grip details.

    Simple-ish parts imported and processed to add lattice-based details to a face selection
    Because that lattice is controlled at an abstracted level, you can very quickly redefine new patterns etc.

    Woah- tell me more (or point me to your research!). My experience with orthopedic implants is all in Titanium (CP or Ti64). I'm a big fan of 's work on the software side for field-driven parametric design of implants.

    My wife and toddler usually start their day looking for Limpy. Now he's gone global. Happy Thanksgiving.

    Elektra showed me your comment on the FB, which is purely a messaging service for me now. Trying to understand 's work has steered my math learning for the past few years, leading me to the geometric algebra.

    The same nosecone as before, but with each 5-axis FDM/FFF layer separately processed for a 2:1 bead aspect ratio. Thickened the centerlines to produce a precise solid of the each half of the toolpath. Then trimmed back with a series of planes for viz.

    Simulation and field-driven five axis FDM/FFF/AFP/ATL? Constant width plies of known width on arbitrary surface curvature? Layers generated from spatially varying offsets that never fail? C-∞ blends? Centerline+Normal and STEP output? Yeah, we're on it.
