1378035 2010.05.20 修正 *六、發明說明： 【發明所屬之技術領域】 本案係關於一種立體成型機構。 【先前技術】 快速成型技術（Rapid Prototyping,簡稱RP技術）係 為依據建構金字塔層層堆疊成型的概念所發展而成，其 主要技術特徵是成型的快捷性，能在不需要任何刀具， 模具及治具的情況下自動、快速將任意複雜形狀的設計 方案快速轉換為3D的實體模型，大大縮短了新產品的研 發周期及減少研發成本，能夠確保新產品的上市時間和 新產品開發的一次成功率，它為技術人員之間，以及技 術人員與企業決策者、產品的用戶等非技術人員之間提 供了一個更加完整及方便的產品設計交流工具，從而明 顯提高了產品在市場上的競爭力和企業對市場的快速反 φ 應能力。 目前RP技術發展出利用喷印技術結合載具精密定位 技術的方式來生產3D的實體模型，其生產方式係為先將 一層粉末舖設於載具上方並利用喷墨列印技術於部分粉 末上喷印高黏度膠合劑，使膠合劑與粉末沾黏並固化， 一直重複上述製程層層堆砌即可完成3D的實體模型。 然而習知RP技術所使用的喷印設備，在不進行喷印 時並無法封存，殘膠會在喷印頭或儲存的維護站内乾 掉，將會造成後續喷印功能性不良，無法繼續喷印產出 1378035 2010.05.20 修正 高品質3D產品。 · 現行的RP技術雖是號稱快速成型技術，但不管成型 物件的尺寸大小或是如何改進快速成型裝置的設備，仍 需花費數小時或數十小時才能成形完成，且在層層堆砌 而成的成品中，當喷印頭本身有阻塞時，若未即時判定 或察覺，就會造成無法補救的時間及物料浪費。 ’ 另外，在使用喷印高黏度膠合劑的方式成形時，膠點 喷出速度高達8m/秒，在此超高速喷液中，當液滴粘黏粉 _ 末那一瞬間，旁邊未被液滴粘黏的奈米級小粉末會因而 反彈飛揚，且在供粉或取件時，推送粉堆掉落時均會產 生粉末到處飛揚的現象，而且習知的設備沒有定量的供 粉機構，需將多餘粉末推入回收筒，會造成粉末掉落時 污染及能源浪費。又，每次舖粉完成後需等待成型乾燥 時間，且成型後須等待數小時乾燥，亦即若成形強度不 足或挖取不慎均可能傷及成品，所以需讓成型品強度夠 強，方可取出，而無法真正達到快速成型的目的。 鲁 因此，如何發展一種可改善上述習知技術缺失之立體 成型機構，實為目前迫切需要解決之問題。 【發明内容】 本案之主要目的，在於提供一種立體成型機構，俾解 決傳統立體成型機構在不進行喷印時無法封存、無法定 量供粉、無法判定喷印頭是否有阻塞、無法防塵以及等 待成型乾燥時間過久等缺點。 4 1378035 , 2010.05.20 修正 ‘ 為達上述目的，本案之一較廣義實施樣態為提供一種 立體成型機構，包含：一基座平台；一列印模組，係可 移動地架構於該基座平台上，並具有至少一列印匣，該 列印匣具有一喷印頭，用以喷印一液體；一定量供粉模 組，架構於該基座平台之一側，用以提供一建構粉末； • 一舖粉裝置，架構於該列印模組之一側並與該列印模組 連動，用以對該建構粉末進行舖粉作業；一建構槽系統， 具有一建構成型區，用以承載該舖粉裝置所舖設之該建 ^ 構粉末，且該列印模組係喷印該液體於其上；一加熱裝 置，架構於該列印模組之一側並與該列印模組連動，俾 於喷印作業之同時對該建構粉末進行加熱作用；一喷印 頭維護裝置，包括一清潔單元及一封存單元；一傳動部 件防塵結構，罩蓋於一傳動部件上，用以阻隔該建構粉 末與該傳動部件接觸；一自動粉末回收裝置，用以吸取 及過濾該立體成型機構運作時所揚起之該建構粉末；以 φ 及一連續供液裝置，用以提供該液體至該列印匣，俾進 行在該建構粉末上之喷印作業。 【實施方式】 體現本案特徵與優點的一些典型實施例將在後段的 說明中詳細敘述。應理解的是本案能夠在不同的態樣上 具有各種的變化，其皆不脫離本案的範圍，且其中的說 明及圖示在本質上係當作說明之用，而非用以限制本案。 請參閱第一圖，其係為本案較佳實施例之立體成型機 1378035 2010.05.20 修正 構之結構示意圖。如第一圖所示，本案之立體成型機構“ 主要係於一基座平台90上架構一列印模組1、一定量供 粉模組2、一舖粉裝置3、一加熱裝置4、一建構槽系統 5、一喷印頭維護裝置6(顯示於第十圖）、一連續供液裝 置7、及一自動粉末回收裝置8 (顯示於第十三圖）。 再者，本案之立體成型機構係於建構粉末上喷印膠合 劑來建構成型立體物件，該建構粉末在舖粉或喷印作業 時會造成塵粉飛揚的工作環境，影響到上述裝置及構件 之正常工作。然而，本案立體成型機構之裝置及構件隨 時均要維持正常運作，是以必須要求整個設備全面性的 絕對防塵，因此，本案之立體成型機構也進一步設置防 塵裝置，該防塵裝置包括有傳動部件防塵結構、舖粉裝 置防塵結構、建構槽系統防塵結構及作業環境防塵結 構，用以防止舖粉及喷印作業所揚起之塵粉污染。 以下就本案立體成型機構上述所提及相關裝置及構 件作詳細說明。 請參閱第二圖A及B，其中第二圖A係為本案較佳 實施例之定量供粉模組之結構示意圖，第二圖B係為第 二圖A之Y-Y剖面圖。如第二圖A及B所示，定量供粉 模組2主要用以定量輸出建構粉末，其至少包括供粉槽 20、推粉滾輪21以及閉合裝置22，其中，供粉槽20為 一中空的槽體結構，可用來儲存建構粉末23，而供粉槽 20内的建構粉末23被堆積於擋板201的第一側面201a 與供粉槽20的第一内壁202之間，並利用内部的第一攪 1378035 2010.05.20 修正 •粉滚輪203攪動建構粉末23，使建構粉末23揚起，再經 由第二攪粉滚輪204的轉動使建構粉末23落至擋板201 的第二側面201b與供粉槽20的第二内壁205之間，另 外供粉槽20的底部更具有落粉開口 206以及落粉通道 207 ° 請參閱第三圖A並配合第二圖B，其中第三圖A係 為第二圖B所示之部分供粉槽及推粉滾輪之結構示意 圖，如圖所示，推粉滾輪21係設置於供粉槽20内部且 鄰近該落粉開口 206,其係作為定量提供舖設於一建構成 型區整個表面一次所需要的建構粉末23，並具有複數個 凹槽211，每一該凹槽211主要用來容置建構粉末23， 當推粉滾輪21之複數個凹槽211與落粉開口 206不相通 時，建構粉末23無法輸出（如第三圖A所示），反之， 當複數個凹槽211的其中之一相對應於落粉開口 206 時，容置於凹槽内之建構粉末23將經由落粉開口 206輸 出（如第三圖B所示）。 另外，本案之定量供粉模組2可根據不同舖粉厚度的 需求來調整推粉滚輪21之複數個凹槽211轉動至與落粉 開口 206對應的次數，以控制建構粉末23的輸出量，可 避免建構粉末23的浪費，舉例而言：若建構成型區的舖 粉厚度的上下限分別為〇.12mm及0.08mm，而推粉滾輪 21的一個凹槽211可容納至少約0.04mm厚度的建構粉 末23，因此當要舖0.08mm厚度的建構粉末23時，步進 馬達（未圖示）須轉動2次，以帶動推粉滾輪21的2個 1378035 20】0.05.20修正 凹槽211與落粉開口 206相連通，使容置於凹槽2〗ι内 的建構粉末23經由落粉開口 206輸出；而當要舖 厚度的建構粉末23時，則步進馬達須轉動3次，以帶動 推粉滾輪21的3個凹槽211内的建構粉末23經由落粉 開口 206輸出，因此可減少多餘的建構粉末23被推入集 粉槽。 請參閱第四圖A及B’其分別為本案第二圖b所示 之推粉滚輪之結構不意圖及前視圖。如第四圖A及b所 示’本案之推粉滾輪21所包含的每一個凹槽211中分別 具有複數個區段A、B及C，於本實施例中，每一凹槽 211中包含一個區段a、二個區段b以及二個區段c，但 不以此為限，其中，區段A係設置於凹槽211之正中央 區域’而區段A之左右兩側分別設有區段b，至於區段 C貝彳設於區段B的另一侧邊，其中區段a之凹槽深度最 淺’谷粉量最少’區段B係較區段A之凹槽深度為深， 其谷粉量略多於區段A，而區段C之凹槽深度相較於區 段A及B為最深，故其具有最大的容粉量，亦即，複數 個區段A、B及C之容粉量係分別由凹槽211之中央朝 兩側遞增，其容粉量係為A<B<C，藉由每一凹槽211具 有複數個區段A、B及C的結構設計以及複數個區段a、 B及C之容粉量係分別由凹槽211之中央朝兩側遞增的 技術特徵，可使建構粉末23均勻舖設於建構成型區上， 進而改善習知技術之建構粉量隨著舖粉的次數造成中央 與一侧差距越來越大的缺失。 1378035 , 2010.05.20 修正 "* 請參閱第五圖A，其係為於第二圖B中設置閉合裝 置及落粉通道之結構示意圖。如第五圖A所示，本案之 定量供粉模組2所包含之閉合裝置22係具有板件221以 及彈性元件222,其中，板件221可移動且具有開口 2211 及第一固定部2212，彈性元件222之一端係連接於該第 一固定部2212，另一端則與供粉槽20之第二固定部208 連接，於供粉槽20供粉時，舖粉裝置3將會朝X方向推 動板件221，使板件221之開口 2211與落粉開口 206相 ® 連通，此時容置於推粉滾輪21其中之一凹槽211内之建 構粉末23會經由落粉開口 206、開口 2211以及落粉通道 207輸出（如第五圖A所示）至舖粉裝置3中（如第六圖A ‘所示）。 反之，當供粉槽20供粉完畢後，舖粉裝置3將會與 板件221分離，此時板件221受彈性元件222之彈性回 復力作用而產生位移，即朝X方向的相反方向移動，以 φ 使板件221之開口 2211與落粉開口 206不相通（如第五圖 B所示），以防止落粉，因此，當立體成型機構運轉時， 閉合裝置22確實可防止微量建構粉末23自供粉槽20内 部外洩，可避免污染工作環境。 請再參閱第一圖及第六圖A及B，其中，第六圖A 係為列印模組、舖粉裝置及加熱裝置之立體結構示意 圖，第六圖B為第六圖A之剖面圖。如圖所示，舖粉裝 置3係設置於列印模組1靠近定量供粉模組2之一侧邊， 且與列印模組1 一起進行左右連動，當進行供粉時，舖 1378035 2010.05.20 修正 粉裝置3會移動至定量供粉模組2之下方，使定量供粉 模組2内之建構粉末落入舖粉裝置3中，以進行後續舖 粉作業。 請參閱第七圖A及B，其中第七圖A為舖粉裝置之 結構示意圖，第七圖B為第七圖A之剖面圖。如圖所示， 舖粉裝置3主要包含舖粉滚輪31及清潔刮片32,其中舖 粉滾輪31係受一馬達33驅動而轉動。當定量供粉模組2 輸出一定量之建構粉末時，建構粉末將落入舖粉裝置3， 並承接於建構槽系統5之粉末承載平台51 (如第九圖所 示）上，再由舖粉滾輪31往建構槽系統5之建構成型區 52方向進行舖粉，以將建構粉末平舖於建構成型區52 的表面上，同時，清潔刮片32可刮險舖粉滚輪31上之 粉末，以充分利用建構粉末，避免建構粉末沾黏於舖粉 滚輪31上。 另外，舖粉裝置3更包含第一板件34及第二板件 35，且其分別具有第一開口 341及第二開口 351。當不進 行供粉，亦即舖粉裝置3遠離定量供粉模組2時，第一 板件34之第一開口 341與第二板件35之第二開口 351 不相連通（如第七圖B所示），可避免建構粉末飛揚而污 染工作環境。而當舖粉裝置3往定量供粉模組2移動以 進行供粉作業時，定量供粉模組2會推抵設置於第一板 件34上之擋部37，使第一板件34往A方向移動，進而 使第一板件34之第一開口 341與第二板件35之第二開 口 351相連通（如第七圖C所示），以使建構粉末落入舖 1378035 .粉裝置3卜待供粉完畢後，舖粉裝置3與定模 組2分離’第_板件3 、疋里供為模 ^ 丨J错由彈性兀件36之彈性回 復力作用而產生位移，回復至第一 341與第二板件35之第 之第一開口 第七圖B所示)。—51不相連通之狀態（如 由於母次舖粉及嗔印完成後需等待成型 2成型時間相當冗長，因此，為達到較快乾燥時速度吏

建構粉末沾黏㈣合劑上加熱供乾，使其與建構粉末黏 、、》〇固化以利再次進行舖粉，縮短總成型時間。在一實 ，例中’加熱裝置4更包含導熱鈑金42，其係大致呈u 子形並朝下方開口’使加熱棒41只對下方之建構粉末進 行加熱。此外，為防止操作人員燙傷，亦可在加熱裝置4 之兩側設置隔熱板43。 再者，為了避免加熱裝置4產生之熱氣對流造成列印 模組1的損壞，加熱裝置更可包含有迴風通道44 (如第 六圖B所示），其可透過管線與抽風裝置（未圖示）相連 1378035 2010.05J20 修正 接，俾將加熱裝置4所產生熱氣的流動方向引導至迴風· 通道44，以避免熱氣流經該列印模組1之列印匣而造成 喷印頭的損壞。 請參閱第九圖，其係為建構槽系統之結構示意圖。如 圖所示，建構槽系統5包含粉末承載平台51、建構成型 區52及四周落粉區53,建構成型區52係由建構槽底板· 521及建構槽體522所共同定義，其中建構槽底板521 係用以承載建構粉末及層層堆疊成型的立體物件，且固 _ 定於升降設備56上，可受升降設備56的帶動而於建構 槽體522的内部進行升降，故於列印模組1每喷印一層 或是生產一定的厚度後，升降設備56將帶動建構槽底板 521往建構槽體522的内部下降。一直到整個立體物件成 型後，升降設備56將帶動建構槽底板521往上升，即可 清除多餘的粉末，並進行取件。 四周落粉區53係設置於粉末承載平台51及建構成型 區52之四周，其係由周壁531與粉末承載平台51及建 籲 構成型區52之間的空間所定義出，用以收集餘粉。因此， 當定量供粉模組2落粉至舖粉裝置3並承接於粉末承載 平台51後，舖粉裝置3之舖粉滚輪31將接著把建構粉 末推向建構成型區52,並平舖於建構成型區52的表面 上，以進行後續喷印作業。而在舖粉過程中多餘之建構 粉末或是喷印過程所揚起之建構粉末即可落入四周落粉 區53，以便自動回收再利用。為有利於餘粉順利收集至 集粉槽中，四周落粉區53内可更包含複數個斜面結構 12 .532 > # x 2010.05.20 修正 ，、八有助於將餘粉順著斜面532導向餘粉自動集粉區 4進而落至餘粉自動集粉154Τ方之集粉槽（未圖示） 中亦可避免粉末直接落下造成塵粉飛揚的情況。另外， 構槽系統5更包含一抽風區55,其係藉由管線與自 動粉末回收裝置8相連通（如第十三圖所示)。 明再參閲第-圖，列印模組j係跨設於建構槽系統5 之上，且列印模組1兩侧設有傳動部件91 (如第十圖所 示）’例如滾珠導螺桿及線性滑鮮，主要用來帶動列印 模組1進行移動。為了防止舖粉或喷印過程所揚起的建 構粉幻占附於傳動部件91上，而造成其使用壽命及列印 精度受影響’本案之立體成型機構更設置有傳動部件防 塵結構’其係由防塵板件92及伸縮防塵護套％所組成， 用、將傳動件91與塵粉飛揚的環境阻隔，以確保傳動 部件91的絕對防塵。其中’防塵板件％可為一金屬板， 係包覆於傳動部件91的周圍，其功能除了阻隔粉末與傳 動部件9!接觸外’更可作為伸縮防塵護套％運走時之 軌道。當列印模組1往左側移動時，伸縮防塵護套％的 左半部會受射彳印難i的浦，#半部則拉 長。反之’當列印模組i往右側移動時，伸縮防塵護套 93的右半部會受到列印模組1的擠塵而收縮，而左半部 則拉長，以達到阻隔粉末與傳動部件91接觸的目的。 為了防止列印模組1之列印匣不運作時，列印匣之喷 印頭上所殘留的膠合劑硬化及飛揚的粉末㈣在喷印頭 上，而導致後續喷印功能不良，無法繼續喷印出高品質 1378035 2010.05.20 修正 的立體物件，因此本案之立體成型機構更設置有喷印頭 維護裝置。請參閱第十圖，其係為立體成型機構之部分 結構示意圖，其中，列印模組被移除以顯示列印模組下 方之結構。如圖所示，立體成型機構之喷印頭維護裝置6 更包含一清潔單元61及一封存單元62。在一實施例中， 清潔單元61與封存單元62係設置於列印模組待機位置 之一侧，其中，清潔單元61可在喷印頭完成喷印作業後， 將喷印頭上殘餘的膠合劑及沾黏的粉末清除乾淨，而封 存單元62則用以封存喷印頭，避免喷印頭受污染或乾化。 請參閱第十一圖，其係為本案清潔單元之結構示意 圖。如圖所示，清潔單元61具有一座體611及至少一刮 板612，其中，刮板612係自座體611表面向上延伸出， 且係對應列印匣而設置，以列印模組1具有兩個列印匣 為例，清潔單元61可具有兩組刮板612，分別對應兩列 印匣而設置，且每一組具有但不限於兩片刮板612，兩片 刮板612係彼此平行設置，且該刮板612可由橡膠材質 製成。當喷印頭完成喷印作業後，列印匣會移動至清潔 單元61上方，當喷印頭經過刮板612位置且與到板612 相接觸時，刮板612即可刮除喷印頭表面上殘餘的膠合 劑及沾黏的粉末。 請參閱第十二圖，其係為本案封存單元之結構示意 圖，如圖所示，封存單元62主要包含基座621、滑座622 及密封部件623，其中，滑座622設置於基座621上，而 密封部件623設置於滑座622上，且部分突出於滑座622 1378035 . 2010.05.20 修正 • ‘之頂表面。密封部件623係用來包覆密封列印匣之喷印 頭，隔離喷印頭與大氣之接觸，以防止膠合劑乾涸而阻 塞喷印頭之喷嘴，同時避免喷印頭受外界粉塵污染。密 封部件之形狀及位置皆係對應列印匣之喷印頭而設置， 故密封部件之數目亦可對應列印匣之數目而變化，不限 於本實施例所圖示之兩個密封部件。 另外，滑座622具有擋件624及至少一頂銷625，其 中，擋件624係自滑座622表面往上延伸出，頂銷625 ® 則自滑座622之側面凸出，且設置於基座621側面之路 徑導執626中。當列印模組1完成喷印作業後，承載列 印匣之承載框架將沿B方向復位至封存單元62上方，而 在復位過程中，承載列印匣之承載框架首先會抵觸於滑 座622上之擋件624，並接著繼續往前推抵該擋件624， 使滑座622側面之頂銷625沿著路徑導軌626移動，因 而密封部件623的高度可以隨著滑座622移動而升高， φ 使密封部件623包覆於列印匣之喷印頭上，故喷印頭可 封存於密封部件623中，避免喷印頭受污染或乾化，更 可進一步延長喷印頭之使用壽命。 請再參閱第一圖，本案之立體成型機構更包含連續供 液裝置7，其係包含複數個供液容器71，該供液容器71 設置於鄰近列印模組1待機位置處，用以儲存列印模組1 喷印所需之膠合劑，且藉由連接管路72之導引及抽吸裝 置（未圖式）之抽吸作用，將内部儲存之膠合劑液體導 入列印匣内，而藉由膠合劑之連續供應，可使列印模組 2長時間連續在建構粉末上崎抖作業。正施 例t，供液容器71為可拆式供液容器。 由於在建構過程中’多餘的建構粉末會由建構槽系統 ::周落粉區53收集至集粉槽54中，然而在舖粉或喷 、時質量較輕或顆粒較小的塵埃粉末可能會飛揚 於内部作業空时，且當建構粉末由四周落粉區53落下

裝置8係藉由管線80與建構槽系統5的抽風區55相連 通主要用來吸取及過濾立體成型機構運作時所飛揚之 塵埃粉末。 請參閱第十四圖A及B，其中第十四圖a為自動粉 末回收裝置之部分結構示意圖，第十四圖B為自動粉末 口收裝置之剖面結構示意圖。如圖所示，自動粉末回收 裝置8主要包含殼體81、粉末過濾元件82、回收構件83 及吸風裝置84,其中殼體81具有吸入口 811，其係藉由 1線80與建構槽系統5的抽風區55相連通，且殼體81 的内部係具有一分隔板812,且分隔板812具有上下連通 1378035 4 2010.05.20 修正 * .之開口 813,該開口 813的上表面周圍係環繞設置一凸環 814。另外，殼體81的内側頂部設置有支撐構件815，其 可為一勾狀結構。 本案之粉末過濾元件82可為一集塵袋，但不以此為 限，粉末過濾元件82的底部係對應該開口 813而套設於 凸環814上，並可透過一密封構件（未圖式），例如一張 力束帶，將粉末過濾元件82以可拆卸方式固定於凸環 814上。該粉末過濾元件82可為但不限於不織布材質， ® 於本實施例中，其實質上呈一圓桶狀結構，且其頂部設 置有一連接部821，該連接部821可為一中空之環狀結 構，但不以此為限，主要用來與支撐構件815可拆卸地 連接，藉由支撐構件815的支撐可將粉末過濾元件82向 上完全撐開，以達到最佳的過濾效果。 本案之回收構件83係為一槽體結構，且設置於分隔 板812下方之空間中，而吸風裝置84可為一鼓風機，設 φ 置於殼體81之上方且具有一吸風口 841與一排風口 842，該吸風口 841係與殼體81内部相連通，藉由吸風 裝置84之運作而分別透過吸風口 841及排風口 842進行 吸氣及排氣，可使殼體81内部形成負壓狀態。如此一來， 當吸風裝置84運作時，即可透過管線80及吸入口 811 將立體成型機構運作時所揚起的塵埃粉末吸入殼體81内 部，且藉由粉末過濾元件82來阻隔吸入之塵埃粉末，使 塵埃粉末不會被吸入吸風裝置84中，可維持吸風裝置84 的正常使用壽命，且當吸風裝置84停止運作後，受粉末 17 1378035 2010.05.20 修正 過濾元件82阻隔之塵埃粉末便自然往下落入回收構件· 83中，可達到絕對防塵與塵埃粉末得以自動回收再利用 的功效。 另外，殼體81更可包括一排出孔85，其平常為封閉 狀態，若有進一步清除殘粉之需求，可外接一吸風裝置 (未圖示），連接至後段處理箱進行更佳的除粉作業。 又，自動粉末回收裝置8更具有前門板86 (如第十三圖 所示），用以與殼體81相組接，使殼體81的内部保持完 _ 全密封的狀態，且在需要清洗或更換粉末過濾元件82，

Description of the invention: [Technical field to which the invention pertains] This case relates to a three-dimensional forming mechanism. [Prior Art] Rapid Prototyping (RP technology) is developed based on the concept of building a pyramid layer stacking. The main technical feature is the rapid molding, without any tools, molds and In the case of fixtures, the design of any complex shape can be quickly and automatically converted into a 3D solid model, which greatly shortens the development cycle of new products and reduces the cost of research and development. It can ensure the time-to-market of new products and the success of new product development. Rate, it provides a more complete and convenient product design communication tool between technicians and non-technical personnel such as technicians and enterprise decision makers, product users, etc., thus significantly improving the competitiveness of products in the market. And the ability of enterprises to respond quickly to the market. At present, RP technology has developed a 3D solid model by using jet printing technology combined with the precise positioning technology of the carrier. The production method is to first lay a layer of powder on top of the carrier and spray it on part of the powder by inkjet printing technology. The high-viscosity adhesive is applied to make the adhesive adhere to the powder and solidify. The 3D solid model can be completed by repeating the above process layer stacking. However, the printing equipment used by the conventional RP technology cannot be sealed when it is not printed, and the residual glue will be dried in the printing head or the stored maintenance station, which will result in poor subsequent printing function and cannot continue printing. Output 1378035 2010.05.20 Corrected high quality 3D products. · Although the current RP technology is known as rapid prototyping technology, it still takes hours or tens of hours to form and build up, regardless of the size of the molded object or how to improve the equipment of the rapid prototyping device. In the finished product, when the print head itself is blocked, if it is not immediately determined or detected, it will cause irreparable time and material waste. In addition, when forming a high-viscosity adhesive, the glue point is sprayed at a speed of up to 8 m/sec. In this ultra-high-speed spray, when the droplets stick to the powder, the end is not liquid. The sticky sticky nano-sized small powder will rebound and fly, and when the powder is fed or picked up, the powder will fly everywhere when the push powder pile is dropped, and the conventional equipment does not have a quantitative powder feeding mechanism. Pushing excess powder into the recovery can cause contamination and energy waste when the powder falls. Moreover, each time after the completion of the powdering, it is necessary to wait for the molding drying time, and it is necessary to wait for several hours to dry after the molding, that is, if the forming strength is insufficient or the inadvertent care may damage the finished product, the molded product needs to be strong enough.
