本論文為對下照式光固化3D列印系統之大面積高速列印所進行的研究,研究目的為找出大面積高速光固化3D列印成型技術中樹脂槽種類的選用、Z軸移動速度和列印面積大小對分離力和列印品質的影響,並歸類出大面積列印下的分離力種類和佔比。
本研究使用的樹脂槽以矽膠做為主要材料,加入自由基擷取劑製成擷取薄膜,此薄膜能夠有效降低下照式光固化3D列印中所產生的分離力,此分離力為影響列印品質和列印速度的重要關鍵。本研究先探討張力型和硬底型樹脂槽在大面積列印條件下的分離力,再探討一般矽膠薄膜和擷取薄膜在大面積列印條件下的分離力,最後探討在大面積列印條件下,不同Z軸移動速度和列印面積對分離力造成的影響,並找出適合的大面積高速列印的參數趨勢和方向。
本研究最後發現擷取薄膜張力型樹脂槽最符合大面積高速列印的條件,相較傳統一般薄膜張力型樹脂槽降低了86.2%分離力,並且藉由Z軸移動速度、列印面積與分離力間的關係,得出適合大面積高速列印的參數調整趨勢,以及歸納出大面積高速列印條件下,三種分離力的大小比較和佔比,提供未來更大面積列印的問題解決方向,以期能突破目前光固化3D列印之瓶頸。
This thesis is a study on the large-area high-speed printing of bottom-exposure 3D printing system. The purpose of this paper is to find the selection of the resin tank type, the effect of Z-axis moving speed and the print area size on separation force and print quality in the large-area high-speed photocuring 3D printing technology, and classify the type and proportion of separation force in large area printing.
The resin tank used in this study uses silicone as the main material, and a free radical scooping agent is added to make a stripping film, which can effectively reduce the separation force generated in the down-light photocuring 3D printing, and the separation force is affected. The key to printing quality and printing speed. In this study, we first discuss the separation force of tension-type and hard-bottom resin tanks under large-area printing conditions, and then discuss the separation force of general silicone film and film under large-area printing conditions. Finally, we will print on large areas. Under the condition, the influence of different Z-axis moving speed and printing area on the separation force, and find the suitable trend and direction of large-area high-speed printing parameters.
In the end of the study, it was found that the film tension type resin groove is the most suitable for large-area high-speed printing. Compared with the conventional film tension type resin groove, the separation force is reduced by 86.2%, and the Z-axis moving speed, printing area and separation are achieved. The relationship between the forces, the parameter adjustment trend suitable for large-area high-speed printing, and the comparison of the size and proportion of the three separation forces under the condition of large-area high-speed printing, providing a solution to the problem of printing in a larger area in the future. In order to break through the bottleneck of current photo-curing 3D printing.
