Abstract: A process for producing a photosensitive resin for 3D printing includes: (i) treating a vegetable oil with a polyol to form a monoglyceride, (ii) reacting the monoglyceride of step (i) with an unsaturated reagent to form a liquid resin with viscosity lower than 20 Pa·s at the temperature of 20° C., and (iii) mixing the liquid resin with a comonomer and a photoinitiator, as well as the photosensitive resin for 3D printing obtainable from such process and the 3D object obtainable from such photosensitive resin.

Abstract: A probe (100) comprises a frame (2), a movable armset (3) and a processing circuit (30; 30?) for processing signals. The processing circuit is able to individually detect the state of contacts (13) defined by the cooperation between mechanical elements of the armset and mechanical elements of the frame, that is the closing or opening of the contacts, and provide a signal indicative of a rest position of the probe when it detects no more than one open contact. A method for processing signals uses said circuit in order to provide a signal indicative of a rest position of the probe. The circuit and the method for processing signals are advantageously implemented for processing the output signals of a touch probe adapted to check dimensions or position of a workpiece in coordinate measuring machines and machine tools.
