Résumé : |
In the USA, large-scale additive manufacturing of thermoplastic composites is moving rapidly from the development laboratory to industrial application. Today, 3D-printed moulds are being printed and used successfully in autoclave production of large aerospace parts, almost every day. |

- Near-net shape
- Truly large robust machines
- Two possible approaches
- Fig. 1 : Thermowood LSAM 10'x20' trimming a marine boat hull pattern made out of ABS. The entire print, assembly and trim process required less than ten working days to complete
- Fig. 2 : This large demonstration part printed on the LSAM MT is one of twenty similar parts which when combined become a production mold for a large yacht hull
- Fig. 3 : Thermwood offers a full line of LSAM sizes to fit almost any application
- Fig. 4 : Above is an example of the different stages of a part after printing and partial trimming on a Thermwood LSAM
- Fig. 5 : Examples of different applications printed and machined on a Thermwood LSAM. The top image is of an unclassified scale nose for a submariene developed in collaboration with the US Naval Surface Warfare Center. This part was printed in 11 hours and 45 minutes. The trim portion took an additional 5 hours. The second image is of a part being printed via VLP (VerticalLayer Printing). This method allows very long parts to be easily printed in one piece. |
