摘要： A novel process is disclosed for extruding an absorbable glycolide/lactide block copolymer into multifilament suture fibers. The block copolymer preferably consists of about 50/50 mole % of Glycolide/Lactide in the center segment and the overall composition of the copolymer is about 90/10 mole % Glycolide/Lactide. The novel extrusion process comprises the steps of maintaining the temperatures of at least two, preferably three or more, of the extrusion zones in the range of about 5 - 50 °C below the polymer melting point. The multifilament suture made with the invention process from the segmented, glycolide-rich, poly(glycolide-co-lactide) copolymers of A-B-A type, where the B-segment is an amorphous prepolymer of glycolide and lactide in the molar ratio of about 50/50 glycolide/lactide, exhibit exceptionally high breaking strength retention (BSR) at 42 days post-implantation.

摘要： 14 Abstract An extruder head for an FFF printing system is described comprising an extruder channel and a heating element (7) for heating part of the extruder channel so as to melt a printing material. The extruder channel comprises a first cylinder (2) and a second cylinder (4) connected to the first 5 cylinder, optionally via an intermediate transition part (3), wherein the extruder head further comprises a Peltier device (10;30) arranged to locally cool a region (11) of the second cylinder so as to make the printing material in the region (11) less or non-flowable. The Peltier device comprises a first heat conductive element (12;32), a second heat conductive element (13;33), and a plurality of thermo-electric units (14;34) arranged between the first and second heat conductive 10 element.

摘要： The present invention relates to an extrusion system comprising a cooled extruder, fixable to a pressing carriage of a machine for quick prototyping with thread of filler material, which comprises, in combination: - means for the controlled and localized heating of the thread of filler material (13), - means for blowing compressed air onto a zone of the extruder to be cooled, placed immediately upstream of the melting zone, with a predetermined flow rate capable of being determined on the basis of experimental tests, - a channel, or conduit, for supplying the thread of filler material (13), conveniently configured to improve the flowability of the thread of filler material therein; wherein said extruder includes a nozzle (1), the body of which is provided with a melting zone in which the melting of the filler material (13) takes place, and with an outlet end for conveying the material on a pressing plane; said nozzle (1) being integral with a heating block (6); wherein said nozzle (1) is made of a material having high wear resistance, corrosion resistance and good workability; and wherein at least at the melting zone of said nozzle (1), the conduit in which the thread of filler material (13) slides, is internally processed with a surface finishing having a roughness from 0.2 to 2.5 pm or less, which ensures a good flowability of the material, reducing or avoiding surface adhesion and risks of vulcanization of the material.

摘要： Eine Extrusionsvorrichtung (100) weist auf: einen Masseneinlass (110) zum Zuführen einer Extrusionsmasse in die Extrusionsvorrichtung (100); einen dem Masseneinlass (110) entlang einer Achse (x) gegenüber angeordneten Massenauslass (120) zum Ausstoßen der Extrusionsmasse aus der Extrusionsvorrichtung (100); ein Massenleitungssystem (115) zum Führen der Extrusionsmasse von dem Masseneinlass (110) zu dem Massenauslass (120); einen auf der Achse (x) angeordneten und entlang der Achse (x) bewegbaren Körper (130), der durch den Massenauslass (120) hindurchtritt und derart ausgebildet ist, dass sich bei Bewegen des Körpers (130) entlang der Achse (x) eine Querschnittsfläche verändert, durch die die Extrusionsmasse aus dem Massenauslass (120) ausgestoßen wird; eine entlang der Achse (x) angeordneten Antriebsvorrichtung (140) zum Bewegen des Körpers (130) entlang der Achse (x); ein Kühlleitungssystem (150) zum Führen von Kühlmittel. Hierbei ist ein erster Teil (152) des Kühlleitungssystems (150) im Inneren des Körpers (130) angeordnet und geeignet, das Kühlmittel entlang der Achse (x) zu führen, ein zweiter Teil (154) des Kühlleitungssystems (150) ist geeignet, das Kühlmittel von der Achse (x) weg aus dem Körper (130) herauszuführen und um die Antriebsvorrichtung (140) herum zu leiten, und ein dritter Teil (156) des Kühlleitungssystems (150) ist geeignet, das Kühlmittel schräg zur Achse (x) nach außen in eine Ableitung (160) für das Kühlmittel zu führen. Entgegen einer Fließrichtung der Extrusionsmasse von dem Masseneinlass (110) zu dem Massenauslass (120) schließt der zweite Teil (154) des Kühlleitungssystems (150) an den ersten Teil (152) des Kühlleitungssystems (150) an und der dritte Teil (156) des Kühlleitungssystems (150) schließt an den zweiten Teil (154) des Kühlleitungssystems (150) an.
