摘要： A method of forming a three-dimensional object in layerwise fashion by selectively solidifying a build material in a reinforced cyclical fashion. The method solidifies a first fully cured layer of build material and then partially solidifies at least one partially cured intermediate layer of build material having areas of liquid build material and areas of solidifying build material. The method repeats the cycle by solidifying a next overlying fully cured layer of build material and also the underlying liquid areas of build material in the at least one partially cured intermediate layer of build material.

摘要： A method of forming a three-dimensional object in layerwise fashion by selectively solidifying a build material. The method solidifies the main part area, delays or pauses for a desired period of time to permit shrinkage to occur, and then, in multiple drawings of the main part borders, solidifies the borders from the portion closest to the main part outwardly to the portion farthest from the main part.

摘要： The present invention relates to a radiation curable ink formulation which has a tan .delta. of from about 0.5 to about 1.5. The radiation curable ink formulation includes a pigment, a radiation cross-linkable monomer or oligomer, and a rheology modifier. Flat panel color filters which contain a black radiation curable ink formulation and one or more colored radiation curable ink formulations are also disclosed. At least one of the black and colored radiation curable ink formulations has a tan .delta. of from about 0.5 to about 1.5 and includes a pigment, a radiation cross-linkable monomer or oligomer, and a rheology modifier. Methods for manufacturing these flat panel color filters are also disclosed. The radiation curable ink formulations of the present invention have the advantage of permitting clean doctoring. When used with black pigments to produce a raised black matrix surface pattern on a transfer layer, intrusion of the black ink into the areas occupied by colored inks is minimal, thus producing flat panel color filters with reduced haze when compared to previously-known flat panel color filters. Also described is a radiation curable formulation containing a radiation cross-linkable monomer or oligomer; a photoinitiator selected from the group consisting of 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-butan-1-one, 2,4,6-trimethylbenzoyl diphenyl phosphine oxide, bis(2,4,6-trimethylbenzoyl) phenyl phosphine oxide, and combinations thereof; and chloropropoxythioxanthone. The radiation curable formulation has exceptionally high cure rate.

摘要： The invention relates to a method producing parts using laser sintering wherein a fusible powder is exposed to a plurality of laser scans at controlled energy levels and for time periods to melt and densify the powder and in the substantial absence of particle bonding outside the fusion boundary. Strength is improved up to 100% compared to previous methods. An example includes a relatively high energy initial scan to melt the powder followed by lower energy scans controlled to densify the melt and separated in time to dissipate heat to the surrounding part cake. The rate and extent to which the powder particles are fused together can be controlled so that each successive scan can be used to fuse the particles together in discreet incremental steps. As a result, the final dimensions of the part and its density and mechanical properties can be improved compared to conventional methods and part growth avoided.
摘要翻译：本发明涉及一种使用激光烧结制造零件的方法，其中熔融粉末以受控的能级暴露于多次激光扫描，并且在熔融和致密化粉末的时间段内，并且在融合边界之外基本上不存在颗粒粘合。与先前的方法相比，强度提高了100％。一个实例包括相对较高的能量初始扫描，以熔化粉末，然后控制较低能量扫描以致熔化熔体并及时分离以将热量散发到周围的部分饼。可以控制粉末颗粒熔合在一起的速度和程度，使得每个连续的扫描可以用于以谨慎的增量步骤将颗粒熔合在一起。结果，与常规方法相比，部件的最终尺寸及其密度和机械性能可以得到改善，并且避免了部分生长。
