3D printing tungsten carbide: soften it, don't melt it
Hiroshima researchers deposited tungsten carbide-cobalt with a laser and hot wire, without fully melting it: over 1400 HV with no defects, and expensive material placed only where it matters.

Printing gears that last: the pure PA11 bet
Prusa launched a carbon-fiber-free PA11 derived from castor oil. A counterintuitive call: for moving parts, the pure version beats the reinforced one on layer adhesion and friction.
This banjo has 19 parts because it had to be simple
The Balloon Banjo uses a party balloon as a tunable resonator. Its better trick is mechanical: making assembly child-friendly deliberately increased the number of printed parts.
This furniture borrows from Carrara’s waste. The material trail stops early
Marmifere borrows its forms from the ravaneti, Carrara’s quarry-waste heaps. Moving from a waste landscape to a recycled-material claim requires one more thing, however: a traceable material source.
These architects build to find out what to design
At TAKK, salazarsequeromedina and Ensamble Studio, a prototype does more than verify an idea. It exposes decisions that drawings cannot settle yet.
They could have generated 100 images. They commissioned four originals
Puresport sent the same kit to four artists and received four different works. The real shift is not AI versus oil but hundreds of possible variants versus four authored originals with rights attached.
The table turns. The real cost starts after that
Greenhill Forge motorised a welding table with Arduino. The gap to a commercial positioner is mostly in published load, torque, speed and welding-current limits.
This 8.8 kg lamp entrusts its light to paper
At Maison Cédrat, clay carries the load, washi diffuses the light, and a set of quiet interfaces lets the shade move or be replaced. The interesting part sits between the materials.
A ₹45,000 extruder still does not turn a bin of waste into filament
NIT Rourkela patented a portable extruder reported at roughly ₹45,000. The more useful question is what still surrounds it: sorting, washing, drying, shredding and qualifying recycled plastic.
The yeast is deactivated before it becomes a 3D-printed panel
At Chalmers, baker’s yeast is not kept alive for effect. It is heated, deactivated, mixed with cellulose and printed at room temperature into lightweight architectural sheets.
