Light-triggered process lets 3D printers create custom glass structures without glue or high temperatures
Researchers have developed the first binder-free method for 3D printing glass, using light to trigger a chemical reaction that directly forms silica structures without the need for organic additives or extreme heat. This breakthrough makes glass printing faster, cleaner, and more precise, with the potential to revolutionize fields from optics to medicine by enabling custom, high-performance glass components that were previously impossible to manufacture.

I'm finally trying printing with Spiderflex (77-82A shore) filament. The print speeds remind me of my first 3d printer. Two tiny parts totaling under 3g took about an hour, printing with a maximum speed of 10mm/s. But having really flexible TPE is really handy; there's really no reasonable alternative!
Now I have new feet for my KX3, and honestly they might be better than the originals (sorry Elecraft!) They are at least as grippy on the table surface, and they are a closer fit on the …

Upscaling Tomographic Volumetric 3D Printing via Virtual Stitching of Coordinated Projections
Tomographic volumetric 3D printing offers layer free, rapid fabrication of objects with high design freedom, but is limited to relatively small curing volumes because of the optical constraints imposed by an assumed need for telecentricity. We present a method to virtually stitch multiple projections from different light sources to build a single workpiece. To avoid the built in requirement for telecentricity and thus the need for an index matching vat, projections are produced by a graphics pr…

ShapeGen3DCP: A Deep Learning Framework for Layer Shape Prediction in 3D Concrete Printing
This work introduces ShapeGen3DCP, a deep learning framework for fast and accurate prediction of filament cross-sectional geometry in 3D Concrete Printing (3DCP). The method is based on a neural network architecture that takes as input both material properties in the fluid state (density, yield stress, plastic viscosity) and process parameters (nozzle diameter, nozzle height, printing and flow velocities) to directly predict extruded layer shapes. To enhance generalization, some inputs are refo…

This sounds like a really cool sci-fi idea: a language model that is special-purpose, cheap and energy efficient and not connected to the internet so it can be built into household appliances. It might be the positive "residue" of an AI bubble crash.
But will those household appliance companies do it? They'd have to let go of their internet connected fridges and data collection. Maybe it'll be the FOSS and 3d-printing community who does it.

Over the past couple weeks, I've been designing a spool with some particular features in #FreeCAD, encompassing 6 parts to 3d-print. I've been manually re-orienting them when I print them.

Recent Advances in Microfluidics and Bioelectronics for Three-Dimensional Organoid Interfaces
Organoids offer a promising alternative in biomedical research and clinical medicine, with better feature recapitulation than 2D cultures. They also have more consistent responses with clinical results when compared to animal models. However, major challenges exist in the longevity of culture, the reproducibility of organoid properties, and the development of non-disruptive monitoring methods. Recent advances in materials and microfabrication methods, such as 3D printing and compressive bucklin…

On design, analysis, and hybrid manufacturing of microstructured blade-like geometries
With the evolution of new manufacturing technologies such as multi-material 3D printing, one can think of new type of objects that consist of considerably less, yet heterogeneous, material, consequently being porous, lighter and cheaper, while having the very same functionality as the original object when manufactured from one single solid material. We aim at questioning five decades of traditional paradigms in geometric CAD and focus at new generation of CAD objects that are not solid, but con…
