Exploring Thermal and Mechanical Strains During Laying Down Process in Fused Filament Fabrication
Macromolecular Materials and Engineering, EarlyView.This study analyzes strain evolution and thermal behavior during FFF of PLA using strain gauges and infrared imaging. Microstrain levels depend on printing conditions, with adhesion‐induced compression during cooling and peak strains in early layers. Microtomography shows minimal porosity, while thermal imaging reveals rapid heat penetration, strong ...

New in-sample prediction errors in time series with applications [PDF]
, 2001 ^aThis article introduces two new types of prediction errors in time series: the filtered prediction errors and the deletion prediction errors. These two prediction errors are obtained in the same sample used for estimation, but in such a way that they ...

Macromolecular Materials and Engineering, EarlyView.Multiscale experiments and DFT calculations establish how polyimide precursor choice governs additively manufactured morphology. PMDA/ODA and PMDA/DDS printed via a polysalt vat photopolymerization route are compared by SEM, SAXS/WAXS, and TGA. PDMA/DDS displays reduced π‐stacking and lower thermal stability compared to PMDA/ODA.

Macromolecular Rapid Communications, EarlyView.We successfully developed poly(ethylene terephthalate) (PET) and poly(ethylene furanoate) (PEF) nanoparticles and microparticles, covalently tagged with Alexa Fluor 633 or Alexa Fluor 647, using both mechanical and solvent‐based approaches. The particles displaying hydrodynamic diameters between 200 and 700 nm, exhibited long‐term colloidal stability ...

View subspaces for indexing and retrieval of 3D models
, 2011 View-based indexing schemes for 3D object retrieval are gaining popularity since they provide good retrieval results. These schemes are coherent with the theory that humans recognize objects based on their 2D appearances.
