Abstract
一种浆料立体光固化成型设备,在一机体设有一刮料平台,所述刮料平台周围的一侧具有外侧为开放端的凹口,在凹口并靠设置一受线性驱动器驱动升降的打印平台,于所述机体设有一马达及一投影装置,所述马达驱动一刮刀以其刀刃旋转扫过刮料平台与打印平台的表面,设有一朝向所述刮料平台出料的浆料给料装置;借由旋转的刮刀能将浆料循环地涂布在逐次下降的打印平台形成多层的浆料层,并以投影装置照射各浆料层使其部分固化为结构层,重复前述操作使结构层堆叠为成品,例如用于烧制为陶瓷的生胚,制造成品快速、精细且无需打印支撑结构。
Description
技术领域
本发明涉及一种3D打印设备;尤其涉及一种浆料立体光固化成型设备。
背景技术
现有打印陶瓷、金属或复合材料的光固化3D打印设备,是在材料槽中倒入调配好的浆料,再以光源选择性的照射在浆料表面的方式,于材料槽中可升降的打印平台上层层固化多个结构层,最终以多个结构层的堆叠形成成品。
上述现有光固化3D打印设备虽能用于打印陶瓷等材料,但打印过程中除了打印主体以外还需要打印支撑结构,而这些支撑结构的设计多需要有经验者进行,及成品需要非常小心的移除;且用于摊平浆料表面的刮刀是以直线运动的方式刮平材料槽中相对高黏度的陶瓷浆料,而只能以较慢的速度铺出层厚最佳只到0.1毫米的等级,使得打印较为费时以外,打印出的成品也不够精致。
发明内容
有鉴于此,本发明的目的在于提供一种浆料立体光固化成型设备,借由刮刀360度连续旋转的方式,在平面的打印平台上循环地形成光固化的浆料层,打印时无需打印支撑结构且借由厚度更薄的浆料层光固化为结构层的方式打印出精细的成品。
缘以达成上述目的,本发明提供一种浆料立体光固化成型设备,包括一机体、一浆料铺平装置、一打印平台位移装置、一投影装置,以及一浆料给料装置。所述机体具有一刮料平台,所述刮料平台的顶面具有一刮料面并且周围的一侧具有一凹口,所述凹口的外侧是开放端并具有一开口。所述浆料铺平装置于所述机体设置一马达,所述马达连接一旋转轴,所述旋转轴结合一刀架,所述刀架设置一刮刀,所述刮刀的边缘具有一刀刃,所述刀刃邻近或抵触所述刮料面,所述刮刀旋转时所述刀刃作用的范围定义为一刮料范围,所述凹口至少部分位于所述刮料范围内。所述打印平台位移装置于所述凹口设置一打印平台,所述打印平台位于所述刮料范围内的边缘并靠于所述凹口的边缘,所述打印平台受一线性驱动器的驱动而线性地升降,所述线性驱动器设置于所述机体。所述投影装置设置于所述机体并具有一镜头,所述镜头朝向所述打印平台的方向。所述浆料给料装置具有一出料口,所述出料口朝向所述刮料范围。
本发明运作时,所述马达会驱动所述刮刀由所述刮刀的初始位置开始沿同一方向旋转,所述浆料给料装置在每次所述刮刀旋转一圈后,将浆料由所述出料口输出至所述刮刀通过所述打印平台后继续前进方向的刮料面上,使所述刮刀将出料口输出的浆料及刮料面上的残料,逐次地铺层在刮料范围的刮料面及打印平台的顶面。
当每次浆料被铺层在所述打印平台的表面时会形成一层浆料层,接着所述打印平台下降相当于一层浆料层厚度的距离,以所述投影装置照射所述浆料层使其部分固化为结构层,重复上述的铺层浆料、打印平台下降以及投影装置照射的过程,使逐次下降后的打印平台上分别形成多个结构层,借由多个结构层堆叠为打印成品,例如用于烧制为陶瓷的生胚,在清洗得到生胚后可将生胚送入高温烧结炉中烧制为陶瓷。
上述浆料在铺层时有低的黏度,但在铺完后其黏度可以而提高,这种浆料可以借由添加入浆料中的可挥发性溶剂或对浆料加热来达到。因为铺层时的低黏度使可以同时达到较高的铺层速度及铺出更薄的层厚。铺完的层可借由溶剂的挥发或浆料冷却而成为高的黏度,而这高黏度的浆料将可对成型中的工件进行支撑保护。也就是说,较高的铺层速度可使打印时间缩短,更薄的层厚及浆料进行支撑保护可以打印出更精致的成品。
本发明的功效在于,刮刀是以旋转方式进行铺层,节省刮刀回程的时间,并且由于浆料的残料会附着于刮刀上,也能避免刮刀回程时浆料的残料掉落于成型区域上而影响加工。此外,由于每次铺层浆料的残料位于刮刀再次旋转时会通过的路径上,使浆料的残料能再度被利用,在制造生产上具有极佳的经济效益。
浆料的配方可以包含挥发性溶剂,可让浆料由给料装置输出时具有较高的流动性,有利于铺层;当完成一次铺层于打印平台后,溶剂挥发而使得浆料层流动性变差,两者的黏度差可让铺层时前一层保有较高的结构性,不被刮刀上的浆料因剪切力而产生位移甚至破坏;同时,挥发后的浆料层因具有较高的结构性,而成为自然支撑,因此打印过程不需建立支撑结构。挥发后的浆料层由于体积变小,而成为固含量高的复合材料工件或生胚,而生胚在经过热脱脂烧失树脂与其他添加剂后及烧结后,可得致密度高的工件。
浆料的配方可以在不同温度有不同的流动性,可让浆料由给料装置输出时加热使具有较高的流动性,有利于铺层;当完成一次铺层于打印平台后,浆料在平台上冷却而使得浆料层流动性变差,两者的黏度差可让铺层时前一层保有较高的结构性,不被刮刀上的浆料因剪切力而产生位移甚至破坏;同时,冷却后的浆料层因具有较高的结构性,而成为自然支撑,因此打印过程不需建立支撑结构。生胚在经过热脱脂烧失树脂与其他添加剂后及烧结后,可得致密度高的工件。

所述机体10具有一刮料平台12,所述刮料平台12的顶面具有一刮料面121,所述刮料平台12周围的一侧朝所述刮料平台12内凹入形成一凹口122,所述凹口122的外侧是开放端并具有一开口123,在本优选实施例中所述凹口122是内窄外宽的梯形凹口,在其他优选实施例中所述凹口122亦可以是扇形或边缘为圆弧形的凹口。
所述浆料铺平装置20具有一马达22,所述马达22设置于所述机体10,所述马达22通过一联轴器221连接一旋转轴24,所述旋转轴24结合一刀架26,所述刀架26设置一刮刀28,所述刮刀28位于所述旋转轴24周围的一侧,所述刮刀28的边缘具有一刀刃281,所述刮刀28可以是软材料或硬材料制成且所述刀刃281邻近或抵触所述刮料面121。请配合参看图5及图7至图8A所示,所述刮刀28旋转时所述刀刃281作用于所述刮料面121的范围定义为一刮料范围A,所述凹口122至少部分位于所述刮料范围A,例如在本优选实施例中,所述凹口122全部位于所述刮料范围A内。
所述打印平台位移装置30具有一打印平台32,所述打印平台32以并靠的方式设置于所述凹口122,所述打印平台32位于所述刮料范围A内的边缘并靠于所述凹口122的边缘,所述打印平台32受一线性驱动器34的驱动而能够沿上下方向线性地升降,所述线性驱动器34设置于所述机体10;当所述打印平台32位于初始位置时,所述打印平台32的顶面对齐所述刮料面121,所述打印平台32可受所述线性驱动器34驱动而降至最低位置。
所述投影装置40具有一镜头42,所述镜头42朝向所述打印平台32的方向照射,所述投影装置40可选用DLP(Digital Light Processing)或LCD(liquid crystal display)的投影机或雷射光扫描装置,所述投影装置40具有高分辨率(FHD、4K甚至8K)可达到欲打印生胚尺寸的精度需求,所述投影装置40照射的光源可以是紫外光、近紫外光或可见光,将对应打印成品各层的层图案以投影或扫描的方式照射在打印平台32上。
请配合参看图1及图8A所示,所述浆料给料装置50具有一出料口52,所述出料口52朝向所述刮料范围A输出浆料,将位于所述出料口52正下方范围的刮料面121定义为一放料区域B,由所述出料口52输出的浆料会落至所述放料区域B的范围。光固化成型所使用的浆料通常包括粉末、粘合剂和溶剂,其中粉末可为聚合物、陶瓷、金属或复合材料的粉末,粉末的细致程度可为纳米、微米等级;粘合剂是光固化树脂;溶剂用于稀释黏合剂,通常为醇基溶剂用以降低浆料的黏度并能更快挥发,亦可使用水来作为黏合剂的溶剂,同时辅以加热来加速挥发,而达到成型区提高固含量及高黏度支撑性。当铺层后的浆料层与由浆料给料装置50所供给的浆料没有相对较高的黏度差异度时,可降低浆料铺平装置20的刮刀28的旋转速度,可达到减低剪切力效果。或例如在出料口52的周围、刮料面121与打印平台32等处设置温度控制装置,借由提高出料口52与刮料面121的温度以降低浆料的黏度,并降低打印平台32的温度以提高浆料层的黏度,达到使浆料与浆料层的黏度具有高差异度,如此亦可于浆料中不需使用溶剂作为稀释剂。
在上述的优选实施例中,所述凹口122以及所述放料区域B的位置是位于所述刮料范围A相反方向的两侧,所述刮刀28还未开始旋转的初始位置是位于所述放料区域B与所述打印平台32之间,当所述刮刀28受所述马达22驱动开始旋转时,是朝向所述放料区域B的方向开始旋转,且所述刮刀28在旋转的过程中都是沿同一方向旋转,所述刮刀28旋转一圈的过程定义为一打印层结构周期。
当所述浆料立体光固化成型设备100运作时,请参看图1及图7至图8C所示的优选实施例,所述马达22会驱动所述刮刀28由初始位置开始沿同一方向旋转,所述浆料给料装置50在每次所述刮刀28旋转一圈,也就是一次打印层结构周期后,将浆料由所述出料口52输出至所述放料区域B上,接着旋转通过所述放料区域B的刮刀28会将刚输出的浆料及前方刮料面121上残留的残料逐次地铺层在刮料范围A的刮料面121及打印平台32的顶面,铺层在打印平台32顶面的浆料会形成一浆料层。
所述打印平台32在每次的打印层结构周期中,在受刮刀28铺层浆料后会下降相当于一层浆料层厚度的距离,接着所述投影装置40以成品的层图案照射所述浆料层使其部分固化为结构层。周而复始地重复上述浆料给料装置50输出浆料、以刮刀28铺层浆料、打印平台32下降以及投影装置40照射浆料层的过程,请参看图9至图10所示,使逐次下降至最低位置的打印平台32上形成多个结构层堆叠而成的精细打印成品,在清洗后得到打印成品。例如打印成品为陶瓷的生胚,可将生胚送入高温烧结炉中烧制为陶瓷成品。
进一步说明上述优选实施例的具体构造,请参看图1至图6所示,所述机体10具有一框架14,所述框架14是镂空的框体构造,于所述机体10的框架14设置一风扇支架16,所述风扇支架16结合一风扇161,所述风扇161持续朝向所述打印平台32顶面的方向送风,如此使所述浆料给料装置50刚输出的浆料可设为具有黏度较低、流动性优选的浆料,而刮刀28铺层在打印平台32顶面的浆料由于其中的溶剂挥发,或受风吹而加速挥发,或者在如图11所示的另一优选实施例中,是将所述打印平台32设为金属平台例如铝板,并且于打印平台32的底侧设有一接触所述打印平台32的温度控制装置37,通过温度控制装置37对所述打印平台32加热而使浆料内的溶剂挥发,使浆料干燥成为黏度较高、流动性较低的浆料层,适合受投影装置40照射成为结构层。另一优选实施例的其余构造与使用方式皆与本优选实施例相同。借由上述风扇161或温度控制装置37的设置可提高所述浆料给料装置50供给浆料的流动性,使刮刀28将浆料铺层于打印平台32顶面时能减低剪切刀造成的位移影响,保有工件的尺寸正确性。溶剂挥发后的浆料层因体积减少而有高的粉末固含量。如打印件为高固含量的生坯,在生胚经过热脱脂烧失树脂与其他添加剂后及烧结后,可得致密度高、强度高的最终工件。
在本优选实施例中所述线性驱动器34是电动伸缩杆且顶端具有一输出端341,所述输出端341结合一打印平台托架36,所述打印平台托架36与所述机体10的框架14之间结合一线性滑轨361,所述线性滑轨361用于导引所述打印平台托架36能受所述线性驱动器34驱动而稳定地升降动作,所述打印平台托架36的顶面具有一轨道362,所述打印平台32的底部具有一与所述轨道362配合的滑动沟321。所述打印平台32朝向所述凹口122的部分可由所述刮料平台12的开口123移入所述凹口122,当所述打印平台32朝向所述凹口122的部分由所述开口123移入所述凹口122的过程中,所述打印平台32的滑动沟321是沿着所述轨道362进入,最终使所述打印平台32设置于所述打印平台托架36上。请参看图11所示,在上述的另一优选实施例中,所述温度控制装置37的具体位置是设置于所述打印平台托架36的顶部,使所述温度控制装置37能接触设置于所述打印平台托架36上的打印平台32,并对所述打印平台32进行加热或冷却的温度控制。
所述机体10的框架14以相反两侧的横梁141形成一打印平台托架142,所述刮料平台12可拆卸地设置于所述打印平台托架142上,所述刮料平台12于对应所述刮料范围A中心的位置形成一转轴穿孔124。所述浆料铺平装置20的马达22位于所述刮料平台12的下方,且所述旋转轴24向上枢穿所述刮料平台12的转轴穿孔124。所述旋转轴24的顶端面具有一剖沟241,所述剖沟241贯穿所述旋转轴24的轴心及其周面相反的两侧,所述剖沟241的底面具有一固定螺孔242,所述刀架26具有内、外两端部,所述刀架26的内端部具有一固定贯穿孔261,所述刀架26的内端部插入所述剖沟241,配合所述固定贯穿孔261设有一固定件21,所述固定件21具有一头部211以及一连接于所述头部211的螺杆212,所述头部211是握把的形状,所述螺杆212穿过所述固定贯穿孔261而螺锁于所述固定螺孔242,将所述刀架26的内端部结合固定于所述旋转轴24。
为了避免刮刀28铺层浆料的过程中,浆料会飞溅在刮料平台12的周围不容易收集残料或者弄脏周围的环境,于所述刮料面121位于所述刮料范围A外的部分设置一第一围栏18,在本优选实施例中所述第一围栏18是C形具有缺口的隔板,所述第一围栏18相异的两端伸抵所述开口123的相反两侧,于所述打印平台32顶面位于所述刮料范围A外的部分设置一第二围栏38,所述第二围栏38是配合所述第一围栏18缺口的隔板,第一围栏18的两端与第二围栏38的两端并靠为环绕于所述刮料范围A周围的圆环形,用于避免浆料向外飞溅。在其他的优选实施例中,所述第一围栏18与所述第二围栏38亦可环绕为方形、多角形或其他环绕的形状。
当需要清洗刮刀28时,是转动拆卸所述固定件21,接着从所述旋转轴24取下所述刀架26与所述刮刀28,即可取走所述刮刀28清洗。当需要清洗回收所述刮料平台12上的残料时,是继拆卸所述刀架26与所述刮刀28后,由所述打印平台托架142向上提起所述刮料平台12,使所述刮料平台12脱离所述旋转轴24,接着倾斜所述刮料平台12使其能由所述框架14的镂空处取出清洗。由于所述第一围栏18与所述第二围栏38拦住向外飞溅的浆料,因此浆料的材料都会残留在所述刮料平台12上,当清洗所述刮料平台12时能回收浆料中的粉末,能借由回收残料的方式避免材料的浪费,降低制造的成本。
所述浆料给料装置50具有一个、数个或多个搅拌槽54,在本优选实施例中所述浆料给料装置50是设有两个搅拌槽54,配合各搅拌槽54设有一蠕动泵56,各蠕动泵56穿置一硅胶管561,各硅胶管561的一端伸入各搅拌槽54,另一端则汇集于所述出料口52,借由上述浆料给料装置50具有两个搅拌槽54的设置,可将不同搅拌槽54内的原料混合调制为浆料于同一出料口52输出。在其他优选实施例中,当所述浆料给料装置50仅设置一搅拌槽54时,所述硅胶管561未伸入所述搅拌槽54的另一端即为所述出料口52,由此出料口52向外输出所述搅拌槽54内的浆料。
所述打印平台32在每次的打印层结构周期中,在受刮刀28铺层浆料后会下降相当于一层浆料层厚度的距离,但所述打印平台32下降时由于所述浆料层与所述刮料面121边缘的浆料会沾黏,因此具体驱动所述打印平台32下降的方式,请配合参看图9及图10所示,是以所述线性驱动器34驱动所述打印平台32先下降超过一层浆料层厚度的距离,使所述线性驱动器34顶面周围的浆料层与所述刮料面121边缘的浆料断开后,再度驱动所述打印平台32上升至相当于下降一层浆料层厚度的距离。
本发明的浆料立体光固化成型设备100除上述说明是用于分次制造打印成品以外,由于所述打印平台32朝向所述凹口122的部分可由所述刮料平台12的开口123移入所述凹口122,因此本发明的浆料立体光固化成型设备100可配合自动化设备进行连续的生产制造。连续的生产制造开始时,是以自动化设备(图中未绘示)将一个打印平台32放置于所述打印平台托架36上,接着风扇161启动朝所述打印平台32顶面的方向持续吹风,配合所述浆料给料装置50在多个打印层结构周期中依次输出浆料,以及所述浆料铺平装置20在多个打印层结构周期的铺层浆料的过程中,以刮刀28旋转将浆料铺层至所述打印平台32的顶面,所述打印平台32在每次受刮刀28铺层浆料后,会下降相当于一层浆料层厚度的距离,接着所述投影装置40以打印成品的层图案照射所述浆料层使浆料层的部分固化为结构层。
当线性驱动器34依次带动所述打印平台托架36及所述打印平台32降至最低位置,且所述打印平台32上的打印成品也打印完成后,自动化设备可由所述打印平台托架36上取出打印平台32及其上的打印成品,例如陶瓷的生胚后送至清洗设备清洗并将生胚烧制成型。在此同时,所述线性驱动器34带动所述打印平台托架36上升至初始位置,所述自动化设备再将新的一个打印平台32放置于打印平台托架36上,开启新一轮的打印成品程序周而复始,使本发明可以连续3D打印产品或生胚,无需在打印出一个打印成品后就中断。
上述本发明的浆料给料装置50将浆料挤出至刮料平台12的刮料面121上、线性驱动器34驱动所述打印平台32依次下降,以及投影装置40照射浆料层等程序的动作过程时间,分别与圆周旋转的刮刀28将浆料摊铺在刮料面121及打印平台32的动作过程时间重迭,每次打印层结构周期的时间相当于刮刀28旋转一圈的时间。如此一来,浆料给料装置50、线性驱动器34及投影装置40等装置的动作与刮刀28旋转的过程同时进行不需要相互等待,可节省生产制造的时间。
以上所述仅为本发明优选可行实施例而已,举凡应用本发明说明书及申请专利范围所为的等效变化,理应包含在本发明的专利范围内。
