SLS et MJF <\/strong><\/h4>\n\n

It is recommended that any sections which are greater in thickness than 7mm for SLS <\/a>or 10mm for MJF<\/a> have hollow sections in order to maintain part geometry and minimise warping. Sections greater than 7mm and 10mm are susceptible to warping due to the concentrated energy (heat) located in the part during printing. <\/p>\n\n

In some cases orientating the part at an angle inside the printer can negate warping, as the reduced cross-sectional area minimises the amount of energy used in the layering process. Where it is recommended to hollow a part it may also be preferable to remove all support material too, therefore a drain hole will be added as well (see Support Material<\/a>)<\/p>\n\n

Ricoh 3D analysera les pi\u00e8ces pr\u00e9sentant de grandes zones sup\u00e9rieures \u00e0 7 mm et les orientera ou les creusera afin de r\u00e9duire les risques de d\u00e9formation lors de l’impression. Cette \u00e9tape sera effectu\u00e9e par nos ing\u00e9nieurs avant l’impression et n’est pas prise en compte lors de la conception. <\/p>\n\n

La prise en compte des trous de drainage et des sections creuses plus \u00e9paisses sera effectu\u00e9e par nos ing\u00e9nieurs avant l’impression, et nous demanderons toujours votre approbation au pr\u00e9alable.<\/p>\n\n

Tous les fichiers envoy\u00e9s \u00e0 Ricoh 3D sont analys\u00e9s avant l’impression. Nous vous informerons de tout probl\u00e8me de g\u00e9om\u00e9trie susceptible d’entra\u00eener des difficult\u00e9s lors de l’impression ou du post-traitement. <\/p>\n\n
