摘要： The present invention concerns a system and a method for collision avoidance of a 3D robotic concrete printer, whereby the method comprises the steps of performing an application and/or manipulation process by executing instructions, such as based on G-Code, with a 3D robotic concrete printer by moving a tool in a path for applying and/or manipulating concrete material; and moving the tool in response to commands to a motion planner, said movement being assisted by a model-based collision prediction system, whereby the model-based collision-prediction system involves the steps of inferring and generating 3D geometries of concrete structures from applying and/or manipulating concrete structures by commanding the 3D robotic concrete printer, using the 3D geometries as a 3D collision model, which allow at any point in time to check if parts of the 3D robotic concrete printer would yield a collision when performing said movement; whereby the 3D collision model of the concrete structure is developed in parallel to the application and/or manipulation process and is updated in correspondence to the progress of the execution of the process instructions.

摘要： A fume extractor system (100) and method for use with a 3D printer (102) includes a system operable in three conditions including: continuously filtering particulates and fumes at high temperatures during a printing process without intentional removal of pressure from the print chamber; continuously filtering particulates at high temperatures during a print process with intentional removal of pressure from the print chamber, to keep noxious gases retained in the print chamber; and purging the print chamber of fumes and mixing in ambient air to cool the fumes to a temperature low enough to allow adsorption of the fumes created by the printer. The system has a first compartment (106) holding a first filter assembly (108) and a second (124) compartment holding a second filter assembly (126).

The light source (201) is configured to provide a light source light and the light reflective component (114) is configured to at least partially reflect at least part of the light source light. The optical component (100) comprises a tubular body (101) having an outer surface (102), and an inner surface (103) opposite to the outer surface (102), the inner surface (102) at least in part forming a cavity (104). The tubular body (101) comprises a first end face (107) and a second end face (108) arranged opposite to the first end face (107). Furthermore, the tubular body (101) comprises a plurality of layers (109) stacked on top of each other extending in a stacking direction (110) of a longitudinal axis (001) of the optical component, each layer (109) encloses part of the cavity (104).

摘要： L'invention concerne un méta-matériau acoustiques (100,100'), ainsi qu'un procédé pour sa fabrication. Le méta-matériau acoustique comprend une pluralité de canaux (101) ou colonnes (101') ayant chacun une même section transversale avec un rayon hydraulique entre 5 et 300 µm, disposés avec un espacement périodique (t,s) entre 2 et 600 µm. On peut ainsi obtenir un réseau hautement dense pouvant offrir une absorption et/ou impédance acoustiques optimales sur une large bande de fréquences. Son procédé de fabrication comprend une fabrication additive avec plusieurs étapes consécutives de dépôt de matériau pour former, dans chaque étape, une couche (203) comportant une pluralité de cellules (204) périodiquement répétées, séparées par des parois (104). Les couches (203) déposées dans les étapes consécutives de dépôt de matériau sont empilées avec leurs cellules (204) respectives alignées de manière à former des canaux (101, 206').
