What is Evaluation of thermoplastic filaments to construct a disposable 3D printed platform for atomic absorption spectrometry about?

Additive manufacturing (AM) is gaining considerable interest due to the inherent capacity of fast and low-cost prototyping of customized devices and parts. In this work, seventeen commercial thermoplastic polymer filaments (PLA, TPU, and ABS) and one PLA pellet for fused deposition modeling (FDM) were characterized and evaluated to develop a disposable sample holder to be used as a solid sampling platform in graphite furnace atomic absorption spectroscopy (GFAAS). For GFAAS application, the selection of polymer filaments took into account no or minimal mass residue, decomposition profile, the lowest thermal decomposition temperatures, and colorless filament (preferably). These conditions are essential for the rapid and complete elimination of polymeric matrix without generating residues inside the graphite tube atomizer and lower analytical blanks. Thus, the filaments and pellets were characterized by thermogravimetry, derivative thermogravimetry, differential thermal analysis, differential scanning calorimetry, Fourier-transform infrared spectroscopy and scanning electron microscopy/energy-dispersive X-ray spectroscopy. It is desirable that the sample holder can be entirely decomp
