Druckverfahren zum Bilden eines kontinuierlichen Strangs (ST) von Baustoff (BS) zum 3D- Druck von einem Bauwerksteil (BWT) mittels eines Drucksystems (20), - wobei das Drucksystem (20) aufweist: - eine Druckvorrichtung (1), wobei die Druckvorrichtung (1) zum Austragen von Baustoff BS) aus der Druckvorrichtung (1) heraus und zum Formen von Baustoff (BS) zum Bilden eines Strangs (ST) von Baustoff (BS) ausgebildet ist, und - eine diskontinuierliche Baustoffpumpe (23), wobei die diskontinuierliche Baustoffpumpe (23) zum diskontinuierlichen Fördern von Baustoff (BS) zum diskontinuierlichen Austragen von gefördertem Baustoff (BS) aus der Druckvorrichtung (1) heraus ausgebildet ist, - wobei das Druckverfahren die Schritte aufweist: - a) diskontinuierliches Fördern von Baustoff (BS) mittels der diskontinuierlichen Baustoffpumpe (23) und diskontinuierliches Austragen von gefördertem Baustoff (BS) aus der Druckvorrichtung (1) heraus und Formen von gefördertem Baustoff (BS) mittels der Druckvorrichtung (1), und - b) diskontinuierliches Bewegen der Druckvorrichtung (1) während des diskontinuierlichen Förderns und des diskontinuierlichen Austragens derart, dass der ausgetragene und geformte Baustoff (BS) einen kontinuierlichen Strang (ST) von Baustoff (BS) bildet.
(EN)
The invention relates to a printing method for forming a continuous strand (ST) of building material (BS) for 3D printing a construction element (BWT) by means of a printing system (20), - the printing system (20) comprising: - a printing device (1), the printing device (1) being designed to discharge building material (BS) from the printing device (1) and to shape building material (BS) to form a strand (ST) of building material (BS), and – a discontinuous building material pump (23), the discontinuous building material pump (23) being designed for the discontinuous delivery of building material (BS) for discontinuous discharging of building material (BS) delivered from the printing device (1), - the printing method comprising the following steps: - a) discontinuously delivering building material (BS) by means of the discontinuous building material pump (23) and discontinuously discharging building material (BS) delivered from the printing device (1) and shaping building material (BS) delivered by means of the printing device (1), and - b) discontinuously moving the printing device (1) during discontinuous delivery and discontinuous discharging in such a way that the discharged and shaped building material (BS) forms a continuous strand (ST) of building material (BS).
(FR)
L’invention concerne un procédé d’impression pour façonner une barre (ST) de matière de construction (BS) pour une impression 3D d’une pièce de construction (BWT) au moyen d’un système d’impression (20). Ce système d’impression (20) comprend : un dispositif d’impression (1), ce dispositif d’impression (1) étant conçu pour évacuer de la matière de construction (BS) contenue dans le dispositif d’impression (1) et pour façonner la matière de construction (BS) en vue de former une barre (ST) de matière de construction (BS), et une pompe à matière de construction (23) discontinue, cette pompe à matière de construction (23) discontinue étant conçue pour refouler la matière de construction (BS) de manière discontinue, de façon à évacuer cette matière de construction (BS) de manière discontinue hors du dispositif d’impression (1). Le procédé d’impression selon l’invention comprend les étapes consistant : a) à refouler la matière de construction (BS) de manière discontinue au moyen de la pompe à matière de construction (23) discontinue et à évacuer cette matière de construction (BS) de manière discontinue hors du dispositif d’impression (1) et à façonner la matière de construction (BS) transportée au moyen du dispositif d’impression (1), et b) à déplacer le dispositif d’impression (1) de manière discontinue pendant le processus de refoulement discontinu et d’évacuation discontinue, de manière que la matière de construction (BS) évacuée et façonnée forme une barre continue (ST) de matière de construction (BS).
