ANALYSIS OF THE CUTTING BLADE FOR HDPE AND PET PLASTIC BOTTLE SHREDDERS FOR 3D PRINTING FILAMENT EXTRUSION

Rekayasa Mesin
The increasing use of filaments for 3D printing encourages the use of suitable plastic waste as a raw material for filaments. In Indonesia, plastic waste will reach 26.2 million tons in 2023, with 18.47% of it being plastic. To process plastic waste such

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

Advanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Equipment and technology for ensuring the strength characteristics of polymer products in 3D printing with composite filament

Известия высших учебных заведений. Поволжский регион:Технические науки
Backround. Polymer products produced by 3D printing are inferior in strength characteristics to cast parts. To increase the strength characteristics, impact strength and heat resistance of products, a composite filament was created, and a technology ...

Structural insights into distinct filamentation states reveal a regulatory mechanism for bacterial STING activation

mBio
The cyclic oligonucleotide-based antiphage signaling system (CBASS) is a bacterial immune mechanism that was evolutionarily linked to the eukaryotic cGAS–STING pathway, which protects against phage infection through abortive cell death.

Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

Advanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

Advanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Low-cost Device to Upcycling PET Plastic Bottle Into 3D Printer Filament

Emitor: Jurnal Teknik Elektro
Plastic waste poses a substantial risk, causing blockages in water channels and contributing to flooding incidents. The accumulation of plastic bottles, which can take 450 to 1000 years to decompose, accelerates environmental degradation. The Ministry of

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

Advanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Implementation of Drug‐Induced Rhabdomyolysis and Acute Kidney Injury in Microphysiological System

Advanced Functional Materials, EarlyView.
A modular Muscle–Kidney proximal tubule‐on‐a‐chip integrates 3D skeletal muscle and renal proximal tubule tissues to model drug‐induced rhabdomyolysis and acute kidney injury. The coculture system enables dynamic tissue interaction, functional contraction monitoring, and quantification of nephrotoxicity, revealing drug side effect‐induced metabolic ...
