Dalla plastica al cibo: il progetto NASA che stampa in 3D biscotti proteici dai rifiuti

Un gruppo di ricercatori della Southern Illinois University Carbondale ha sviluppato μBites, un biscotto proteico stampato in 3D ottenuto trasformando rifiuti plastici e agricoli in ingredienti alimentari. Il pr

LLNL 3D prints ceramic lasers to overcome the limits of optical fibers

Researchers at Lawrence Livermore National Laboratory have created the first all-ceramic laser waveguide using 3D printing. The device, based on yttrium aluminum garnet doped with ytterbium (Yb:

Michigan launches a new center for additive manufacturing, while 3D printing revolutionizes medicine and architecture

Automation Alley e Oakland University hanno inaugurato un centro di eccellenza per la manifattura avanzata in Michigan. Intanto, chirurghi israeliani hanno salvato una paziente oncol

3D-printed coral-inspired scaffold reprograms immune cells to regenerate bone

Chinese researchers have developed a 3D-printed biomimetic scaffold that not only provides a structure for bone growth, but also actively intervenes in the immune environment of the area

Cyborg cockroaches with 3D-printed suit for underwater operations

Researchers from Nanyang Technological University and Waseda University have developed a 3D-printed underwater suit that allows cyborg cockroaches to operate underwater for hours. The system, published in Nature Comm

Controlled vibrations improve strength and adhesion of PLA in FFF printing

A group of researchers has developed an FFF 3D printing system that integrates controlled mechanical vibrations during material deposition. The goal is to solve one of the main limitations of the technology

3D scanning and printing bring a 1,700-year-old Roman game board back into play

An ancient stone game board used in Roman Britain has been reproduced thanks to 3D printing. The project by Newcastle University and the Vindolanda Charitable Trust has allowed the creation of a faithful replica of

Fiber optic sensors integrated in large-format 3D printing: ERDC research

Researchers at the U.S. Army ERDC have demonstrated that it is possible to embed fiber optic strain sensors during large-format additive manufacturing without modifying the basic printing process.

A book that prints itself: Manual and the G-code embedded in its pages

Manual is a 3D printed book that contains the machine code used for its own production. Made in TPU with an innovative printing method, it represents a radical experiment on the limits of manufacturing.

Ricercatori della Texas A&M University hanno sviluppato una tecnica rivoluzionaria di stampa 3D metallica a livello nanometrico. Il processo nPIMET usa elettroni caldi per costruire strutture metalliche sotto i 250 nanometri, senza maschere né supporti, con energia ridotta del 99% rispetto ai metodi tradizionali.

La stampa 3D reinventa scaffold medici con microcanali esagonali per i nervi e strutture gyroid per le ossa. Materiali approvati e geometrie intelligenti migliorano la rigenerazione, ma validazione clinica e normativa sono ancora necessarie.

Modelli computazionali e machine learning consentono di prevedere proprietà e comportamento di leghe avanzate come HEA e RCCA prima della produzione, accelerando lo sviluppo di materiali su misura per applicazioni estreme in aerospaziale e industria.
