Abstract: The invention is in the field of additive manufacturing. According to a first aspect of the invention, there is provided an additive manufacturing process for producing a printed article, comprising the step of sintering a powder composition comprising a thermoplastic elastomer, wherein the powder composition has a melting onset temperature Tm,onset and a melting peak temperature Tm,peak, which are measured according to ISO 11357-1/3 (2009), wherein Tm,peak minus Tm,onset is 30° C. or less; and wherein a test article printed from the powder composition has a rebound resilience of 50% or more, measured according to DIN 53512.

Abstract: A system for determining the work time of a work tool is disclosed. The system has a work tool. The system also has a work tool movement sensor adapted to produce a signal indicative of a movement of the work tool. The system further has a controller adapted to produce a signal indicative of a work time of the work tool as a function of the movement of the work tool.

Abstract: A separating device for coolants or lubricants, containing chips, is described. This is provided with a supply line (11), a container (10) as well as a pump (20), which is connected with the container (10). The pressure side of the pump is connected with a discharge line (28). The pump, in particular, is an unchokable pump. A device (13), for comminuting the chips supplied, is disposed in the container (10).

Abstract: A pumping station for pumping a cooling and lubricating fluid containing particulate matter such as machining chips has a compact structure with a relatively low total structural height, while still assuring that the chips are conveyed with the fluid to the pump suction inlet, without settling-out or accumulating in the apparatus. The pumping station (1) includes a collecting container (5) with at least one pump (6) arranged therein, a chip breaker (7) and a supply conduit arrangement. The supply conduit arrangement includes a supply line (2) through which the cooling and lubricating fluid containing the machining chips is received from a machining tool or transfer station. Furthermore, two branch lines (3) and (4) are interposed and connected between the supply line (2) and the collecting container (5). A first branch line (3) conveys the fluid, from which the chips have been removed, with a slight downward slope toward the collecting container (5).
