<\/p>\n
Il suffit de cocher une option dans votre logiciel slicer ( tranchage ) et le raft se fait automatiquement.<\/p>\n
Il permet d’avoir une plus grande surface d’adh\u00e9sion entre le plateau et votre pi\u00e8ce et il peut \u00eatre utilis\u00e9 \u00e9galement pour compenser un plateau dont la surface n’est pas bien plane.<\/p>\n
Le raft est ensuite enlev\u00e9 \u00e0 la main apr\u00e8s impression.<\/p>\n

Inconv\u00e9nients :<\/strong> <\/span>
– temps d\u00a0\u00bbimpression du raft qui s’ajoute \u00e0 celui de la pi\u00e8ce.
– plus de mat\u00e9riaux utilis\u00e9 pour faire le raft
– laisse des traces en dessous de la pi\u00e8ce<\/p>\nRemarque : <\/strong><\/span>Le raft permet aussi de r\u00e9soudre le probl\u00e8me inverse, une pi\u00e8ce tr\u00e8s difficile \u00e0 d\u00e9coller du plateau car la surface en contact est tr\u00e8s grande, le raft \u00e9tant un quadrillage, la surface en contact du plateau n’est jamais tr\u00e8s importante.<\/p>\n <\/p>\n
b ) Solution des pastilles de fixation<\/strong><\/span><\/p>\n![\"pastilles-fixation\"](\"http:\/\/www.makerslide-machines.com\/wp-content\/uploads\/2017\/08\/pastilles-fixation.jpg\")
<\/p>\n
Vous devez ajouter ces pastille avec votre logiciel de conception volumique avant l’export au format STL ou OBJ.<\/p>\n
Ces pastilles ne devront pas faire plus de 0.5mm d’\u00e9paisseur pour pouvoir \u00eatre ensuite retir\u00e9es \u00e0 la main apr\u00e8s impression.<\/p>\n
Elles sont utiles \u00e9galement contre le wrapping et ces pastilles devront \u00eatre dispos\u00e9s dans les coins.<\/p>\n

<\/p>\n
L’option \u00ab\u00a0Brim<\/strong>\u00a0\u00bb permet d’avoir une bordure tr\u00e8s fine qui s’imprime automatiquement autour de l’objet.<\/p>\nLa largeur de cette bordure est param\u00e9trable, elle peut \u00eatre augment\u00e9e ou diminu\u00e9e, selon le risque de wraping plus ou moins \u00e9lev\u00e9 de votre pi\u00e8ce.<\/p>\n
La bordure peut se retirer ensuite \u00e0 la main apr\u00e8s impression.<\/p>\n
