TL;DR: The aim of this review is to present a guide for new users of3D-printing technology considering the required features for improved electrochemical sensing using 3D-printed sensors and devices already reported using selective laser melting and fused deposition modeling 2D-printers.

TL;DR: Proposed 3D-printed sensor, which presented comparable electroanalytical performance with other carbon-based electrodes, demonstrated for the amperometric detection of tert-butylhydroquinone, dipyrone, dopamine and diclofenac by flow-injection analysis (FIA) and batch-injected analysis (BIA).

TL;DR: The electrochemical performance of the developed system was similar or better than those obtained using commercial glassy carbon and screen-printed carbon electrodes and represents a significant advance in AM (3D-printing) technology for analytical chemistry.

TL;DR: In this article, an enzymatic glucose biosensor fabricated on the G-PLA surface was developed and applied for glucose sensing in blood plasma using chronoamperometry, achieving a limit of detection (LOD) of 15 μmol L−1, inter-day and intra-day precision lower than 5 %, and adequate recovery values (90-105 %) for the analysis of plasma.

TL;DR: In this paper, traces of 2,4,6-Trinitrotoluene (TNT) impregnated on different surfaces were abrasively sampled using the 3D-printed device and readily assembled in a portable electrochemical cell for rapid square-wave voltammetry scans in the presence of 0.1 mol 1 HCl electrolyte.
