Title
(EN) FILAMENT FOR THREE-DIMENSIONAL PRINTING
(FR) FILAMENT POUR IMPRESSION TRIDIMENSIONNELLE

Abstract
(EN)
The present invention pertains to a filament for three-dimensional printing, the filament containing an olefin-based resin composition (α) satisfying 700≥24×ΔHc(α)-E’(α). ΔHc(α) is the heat of crystallization (J/g) of the olefin-based resin composition (α) as measured at a cooling rate of 10 °C/min by a differential scanning calorimeter, and E’(α) is the storage modulus (MPa) of the olefin-based resin composition (α) as measured with 10 Hz at 40°C.
(FR)
La présente invention concerne un filament pour impression tridimensionnelle, le filament contenant une composition de résine à base d'oléfine (α) satisfaisant 700 ≥ 24 × ΔHc(α)-E'(α). ΔH (α) est la chaleur de cristallisation (J/g) de la composition de résine à base d'oléfine (α) mesurée à une vitesse de refroidissement de 10°C/min par un calorimètre à balayage différentiel, et E'(α) est le module de conservation (MPa) de la composition de résine à base d'oléfine (α) telle que mesurée avec 10 Hz à 40°C.
(JA)
本発明は、700≧24×ΔHc(α)-E´(α)を満たすオレフィン系樹脂組成物(α)を含有する、3次元造形用フィラメントに関する。ΔHc(α)は、該オレフィン系樹脂組成物(α)を示差走査熱量計にて10℃/分の降温速度で測定した際の結晶化熱量(J/g)であり、E´(α)は、該オレフィン系樹脂組成物(α)を40℃及び10Hzで測定した貯蔵弾性率(MPa)である。
