A thermodynamic framework has been developed for a class of amorphous polymers used in fused deposition modeling (FDM), in order to predict the residual stresses and the accompanying distortion of the geometry of the printed part (warping). When a polymeric melt is cooled, the inhomogeneous distribution of temperature…

Fused Deposition Modeling (FDM) is one of the most widely explored additive manufacturing method that uses thermoplastic materials to manufacture products. Mechanical properties of parts manufactured using FDM are influenced by different process parameters involved during manufacturing as they impact the bonding among…

Dark matter may be composed of ultra-light bosons whose de Broglie wavelength in galaxies is λ ∼ 1 kpc. The standard model for this fuzzy dark matter (FDM) is a complex scalar field that obeys the Schr¨odinger-Poisson equations. The wavelike nature of FDM leads to fluctuations in the gravitational field that can pump…

Chemoenzymatic techniques have been applied extensively to pharmaceutical development, most effectively when routine synthetic methods fail. The regioselective and stereoselective construction of structurally complex glycans is an elegant application of this approach, that is seldom applied to positron emission…

An empirical baryon density profile can be included in the Schr¨odinger-Poisson (SP) equations to influence the fuzzy dark matter (FDM) soliton formation. However, to probe the effects of baryon on the other dynamical evolutions of the FDM soliton, its equation of motion (EoM) inside the corresponding FDM soliton is…

Although 3D printers are becoming more common in households, they are still underrepresented in many laboratories worldwide and regarded as toys rather than as laboratory equipment. This short review wants to change this conservative point of view. This mini-review focuses on Fused Deposition Modeling (FDM) printers…
