Abstract
Among engineering materials today continuous fiber reinforced polymers (FRP) show some of the highest stiffness and strength to weight ratios. To rival the traditional manufacturing methods of continuous FRP many investigations have sought to combine the outstanding mechanical performances of these materials with the freedom in design and the economic benefits of additive manufacturing (AM). This paper focuses on the fiber placement strategies and their interaction with Selective Laser Sintering (SLS) specific machine features. The goal is to develop and conduct test series to gain a deeper understanding of how the process, the polymer, and the reinforcement fibers interact. For this investigation different patterns of glass fiber rovings are embedded into specimens made from PA 12 on a Sintratec Kit printer. The rovings are put up onto a frame in varying patterns to be able to relate fiber tension and curvature as well as the stack height of intersecting rovings to the quality of embedding. Additionally the time of placement, the clamping and the interaction of the fibers with the recoater have been investigated. Based on these results an SLS printer with automated continuous fiber implementation will be developed in the future.

Abstract
Additive Fertigungsverfahren erlauben ohne die Grenzen herkömmlicher Werkzeuge eine nahezu unbegrenzte Designfreiheit. Zur Steigerung von Produktlebenszyklen werden bereits Hybridisierungskonzepte durch Integration von Verstärkungsfasern erforscht. Im vorgestellten Forschungsprojekt wird eine Prototypenanlage entwickelt, mit der sich Endlosfasern in das selektive Lasersintern (SLS) von Kunststoffbauteilen automatisiert integrieren lassen.

Abstract
Die additive Fertigung erlaubt eine standortunabhängige sowie de facto individualisierte Produktion von Bauteilen mit nahezu beliebiger Komplexität. Für die flexible Herstellung von hochfunktionalen Hybridbauteilen fehlt es allerdings an entsprechenden Maschinenkonzepten sowie Automatisierungslösungen. Durch ein hier vorgestelltes Anlagenkonzept sollen Funktionskomponenten in den additiven Herstellungsprozess integriert und neue Möglichkeiten der Bauteilhybridisierung erforscht werden.

If you did not include a short abstract for the online version when you submitted the manuscript, the first paragraph or the first 10 lines of the chapter will be displayed here. If possible, please provide us with an informative abstract. One of the main advantages of additive manufacturing by fused filament fabrication is its wide variety of materials and cost-effective production systems. However, the resolution and tightness of the produced structures are limited. The following article describes a novel approach of the functional integration of stereolithographic produced subcomponents into the fused filament fabrication process and the challenges during integration in terms of adhesion, taking into account different surface pre-treatments. With the help of these investigations, it is aimed to extend the field of application of additive manufactured plastic components.
