Gravure laser de notre logo sur la<\/em><\/strong>
section d’une branche d’arbre d’environ 5cm de diam\u00e8tre<\/em><\/strong><\/figcaption><\/figure>

La gravure\n laser est une m\u00e9thode de fabrication soustractive, qui se base sur \nl\u2019utilisation d\u2019un faisceau laser pour alt\u00e9rer la surface d\u2019un objet.<\/p>

Ce proc\u00e9d\u00e9 permet de cr\u00e9er des images visibles \u00e0 l\u2019oeil nu sur l\u2019objet. Le laser \u00e9met une chaleur assez \u00e9lev\u00e9e pour pulv\u00e9riser la mati\u00e8re, formant ainsi des cavit\u00e9s qui formeront l\u2019image finale. C\u2019est une m\u00e9thode rapide, la mati\u00e8re \u00e9tant enlev\u00e9e \u00e0 chaque impulsion du laser. La profondeur des marques et l\u2019\u00e9paisseur du trait sont g\u00e9r\u00e9es par le nombre de passages du faisceau sur le mat\u00e9riau.<\/p>

La gravure laser peut \u00eatre utilis\u00e9e sur presque tous les types de m\u00e9tal, plastique, bois, cuir, ou verre. Qui plus est, c\u2019est un proc\u00e9d\u00e9 plus efficace que la gravure traditionnelle pour les petits objets, tels que les bijoux. En effet, il y a beaucoup moins de risques d\u2019endommager ou de d\u00e9former la mati\u00e8re.<\/p>

Contrairement \u00e0 toutes les autres techniques que nous utilisons (r\u00e9sine, d\u00e9coupe num\u00e9rique, impression 3D) elle ne permet que de r\u00e9aliser des objets en 2D bien qu’il soit possible en modulant la puissance du laser , la vitesse de la t\u00eate laser d’aussi cr\u00e9er des illusions 3D en travaillant avec des calques\/couches mais toute superposition est impossible vu que le mat\u00e9riau de travail est “br\u00fbl\u00e9”<\/p>

<\/p>

Il existe principalement 3 types de laser rencontr\u00e9s:
– Le laser diode utilis\u00e9 en hobby et par les petits artisans
– Le laser au CO2 (le rayon laser est g\u00e9n\u00e9r\u00e9 dans un tube herm\u00e9tique contenant du CO2)
– Le laser “Fibre”, le laser est g\u00e9n\u00e9r\u00e9 et le rayon passe dans une fibre optique avant d’arriver dans le systeme optique qui lui dirige ce rayon vers l’objet.

Chaque type de laser \u00e0 une longueur d’onde (rayon lumineux) sp\u00e9cifique et aussi un domaine d’application sp\u00e9cifique et surtout un co\u00fbt machine.

Pour la gravure du bois un laser diode, voir CO2 suffit amplement.<\/p>
