Abstract
Description
本創作係隸屬一種3D列印機的原料條，特別係指以天然植物的纖維、澱粉等為原料製成的原料條。 This creation belongs to a kind of raw material bar for 3D printer, especially refers to the raw material bar made of natural plant fiber, starch, etc.
按，3D列印在產品成的製造成型上能打破所有設計上的限制，亦無應用產業上的限制，可在不受限於製造方法或成本之下，基於機能性進行製品的設計，因此機近十年來發展蓬勃，不論是航太、醫療、汽車、玩具、文創及各種產品的研發，各個領域都有將3D列印使用於產品的打樣和製造。然而，就產品的打樣而言，一般的3D列印機都是使用塑膠材質的膠條，打樣出來的成品不論是否符合要求，樣品丟棄或燃燒時都會對環境造成不良的影響，因此如何能研發出3D列印機列印用的原料條，便成為申請人思及的方向。 According to the data, 3D printing can break all design restrictions in product manufacturing and has no restrictions on application industries. It can design products based on functionality without being restricted by manufacturing methods or costs. Therefore, the machine has been booming in the past decade. Whether it is aerospace, medical, automobile, toy, cultural and creative, or the development of various products, all fields have used 3D printing for product proofing and manufacturing. However, in terms of product proofing, general 3D printers use plastic strips. Regardless of whether the finished product meets the requirements, the sample will have a negative impact on the environment when it is discarded or burned. Therefore, how to develop a raw material strip for 3D printer printing has become the direction of the applicant's thinking.
本案申請人先前創作係申請案號108102795號，可生物分解之植物纖維原料的組成物及其製造方法發明專利(以下簡稱習用一)，該習用案係揭露一種植物纖維製成的原料粒，該原料粒的成分完全不需要水分，包含：植物纖維粉40~60%、澱粉20~30%、澱粉發酵的植物膠粉末10~20%、水溶 性高分子膠5~10%，以及纖維素蛋白質3~5%；將上述的配方經過加熱混煉成若干料條後，再利用一切削單元將該等料條切削呈顆粒狀製成原料粒。 The applicant of this case previously created a patent application No. 108102795, a composition of biodegradable plant fiber raw materials and its manufacturing method (hereinafter referred to as Application 1). The application discloses a raw material pellet made of plant fiber, the ingredients of which do not require water at all, including: 40~60% plant fiber powder, 20~30% starch, 10~20% plant glue powder fermented from starch, 5~10% water-soluble polymer glue, and 3~5% cellulose protein; the above formula is heated and mixed into a number of material strips, and then a cutting unit is used to cut the material strips into granules to make raw material pellets.
其次，本案創作人為改良習用一，另有二專利案揭露了新的原料粒配方，其分別是申請案號110105195『植物纖維原料粒的組成及其應用之纖維瓶罐成型方法』，及申請案號110105196『纖維袋體之成型方法』專利案，該二件專利案揭露的纖維原料粒配方都是為：植物纖維粉41~59%、澱粉21~29%、天然黏合劑8~28%，該天然黏合劑由澱粉添加二羧酸及發酵用的菌種製成、水溶性高分子膠6~12%、改性劑3~5%，以及滑劑0.01~0.2%。上述配方製造的原料粒能利用專用機器製成纖維瓶罐或袋體，取代塑膠材質的容器產品。 Secondly, the creator of this case improved the first practice, and two other patents disclosed new raw material pellet formulas, namely application number 110105195 "Composition of plant fiber raw material pellets and fiber bottle molding method using them", and application number 110105196 "Fiber bag molding method". The fiber raw material pellet formulas disclosed in these two patents are: plant fiber powder 41~59%, starch 21~29%, natural adhesive 8~28%, the natural adhesive is made by adding dicarboxylic acid and fermentation bacteria to starch, water-soluble polymer glue 6~12%, modifier 3~5%, and lubricant 0.01~0.2%. The raw material pellets made with the above formula can be made into fiber bottles or bags using special machines, replacing plastic container products.
隨著3D列印機的盛行，申請人將上述研發完成的纖維原料粒製成符合3D列印機使用的料條並試驗時，發現因為3D列印機打印模組加熱的溫度大約170度，其將纖維料條加熱的過程中會使纖維材料產生碳化的現象，不僅無法順利的將纖維材料融化堆疊產品，也會造成噴嘴的阻塞，而有針對原料粒的配方再進行改良之必要。 With the popularity of 3D printers, the applicant made the fiber raw material pellets developed above into material strips suitable for 3D printers and tested them. It was found that because the heating temperature of the 3D printer printing module is about 170 degrees, the fiber material strips will be carbonized during the heating process. Not only can the fiber material not be melted and stacked smoothly, but it will also cause nozzle blockage. It is necessary to improve the formula of the raw material pellets.
有鑑於此，本創作人乃針對前述習用創作問題深入探討，並藉由多年從事相關產業之研發與製造經驗，積極尋求解決之道，經過長期努力之研究與發展，終於成功的開發出本創作『用於3D列印之植物纖維料條的組成及其製造方法與其應用的3D列印機結構改良』，以改善習用創作之問題。 In view of this, the creator of this work has conducted in-depth research on the aforementioned practical creation problems, and actively sought solutions through years of research and manufacturing experience in related industries. After long-term research and development, he finally successfully developed this creation "The composition and manufacturing method of plant fiber strips for 3D printing and the improvement of the 3D printer structure for its application" to improve the problems of practical creation.
本發明之主要目的，係提供一種『用於3D列印之植物纖維料條的組成及其製造方法與其應用的3D列印機結構改良』，其係令3D列印機使用的原料條能以植物纖維原料製成，減少塑膠原料對環境的破壞。 The main purpose of this invention is to provide a "composition of plant fiber material strips for 3D printing, its manufacturing method and the improved structure of the 3D printer used therein", which enables the material strips used in 3D printers to be made of plant fiber raw materials, thereby reducing the damage of plastic raw materials to the environment.
本發明之另一目的，係令3D列印機將纖維料條加熱融化進行產品的堆疊成型時，纖維原料能順暢穩定將融化的原料擠出，避免材料堵塞的情形。 Another purpose of the present invention is to enable the 3D printer to heat and melt the fiber strips for stacking and forming the product, so that the fiber raw materials can smoothly and stably squeeze out the melted raw materials to avoid material blockage.
