彼此之間係水平且分離設置，而供粉槽12底部所設置之 開孔126彼此之間亦同樣呈水平且分離設置，因此可以分 段的落粉方式於建構槽13上進行供粉，以使建構槽13上 的舖粉密度一致，可解決習知技術於開始供粉時就一次提 0 供所有的粉量’造成開始推粉時因為重量及推擠，形成前 段與後段舖粉的密度不平均及過多剩餘粉末推至回收槽 14内的問題。 再者，由於每次舖粉及噴印完成後需等待成型乾燥時 間’習知技術約每舖粉一次就要等三分鐘粉末乾燥黏著時 間’大大增加了總成型的時間，因此，為達到較快乾燥速 度，本案之桌上型立體成型裝置1更包含一加熱組件17 (第一圖B所示）’其係設置於供粉槽12之前端，可在每 次噴印完成後對粉末進行加熱作用，以加速粉末乾燥黏著 9 201036807 1 之速度，縮短總成型時間。在一實施例中，加熱組件17 可更包含一感溫器171，可感測加熱組件17之溫度，以做 適度之溫度控制。 請參閱第二圖A，其係為本案桌上型立體成型裝置之 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，本案之桌上型立體成型裝置1更 包含一喷頭清潔裝置30及一喷頭封存裝置40。在一實施 ^ 例中，喷頭清潔裝置30與喷頭封存裝置40係設置於列印 模組待機位置之一侧（例如左侧），其中，喷頭清潔裝置 30可在喷頭完成喷印作業後，將喷頭上殘餘的膠合劑及沾 黏的粉末清除乾淨，而喷頭封存裝置40則可在喷頭封存 時提供濕潤的環境，避免喷頭乾掉。 請參閱第二圖B，其係為本案噴頭清潔裝置之結構示 意圖。如圖所示，喷頭清潔裝置30具有盒體31、基座32、 驅動裝置33及至少一刮板34，基座32係容置於盒體31 ❹ 中，且可受驅動裝置33驅動，而於X方向上往復運動。 刮板34係自基座32表面向上延伸出，且係對應喷印匣而 設置，以列印模組具有兩個喷印匣為例，喷頭清潔裝置30 可具有兩組刮板34,其係對應兩喷印匣而設置，且每一組 具有但不限於兩片刮板34，且兩片刮板34係彼此平行設 置，且該刮板可由橡膠材質製成。當喷頭完成喷印作業 後，喷印匣會被移動至喷頭清潔裝置30上方，且喷頭對 應於刮板34位置且與刮板34相接觸，此時，驅動裝置33 驅動基座32於X方向上往復運動，可使得刮板34於喷頭 201036807 表面移動以刮除喷頭上殘餘的膠合劑及沾黏的粉末。 另外，由於膠合劑及粉末易黏附於喷頭上，難以刮除 完全，因此，本案之喷頭清潔裝置30更具有一喷液系統， 包含儲液槽35、抽液管36、喷液管37及廢液管38，儲液 槽35係相鄰於盒體32而設置，且透過抽液管36將液體 自供液裝置（係設置於第一圖A之基座平台10下方，未 顯示）輸送至儲液槽35中，並利用喷液管37將液體喷送 ^ 至喷頭，其中，喷液管37之喷液口 371係緊鄰刮板34而 設置，且喷液口 371之數目較佳與刮板34之組數相同， 例如，當列印裝置具有兩個喷印匣時，喷水清潔裝置30 即具有兩組到板34及兩個喷液口 371。 因此，當喷頭完成喷印作業且移動至喷頭清潔裝置30 上方時，喷頭清潔裝置30會先對喷頭喷出些微液體，其 中該液體可為但不限於水、清潔劑或溶劑，用以潤濕噴頭 上的膠合劑及粉末，可使得刮板34清潔喷頭時更加方便 〇 容易，故隨後於驅動裝置33帶動刮板34於喷頭表面移動 時，可輕易將喷頭上殘餘的膠合劑及沾黏的粉末刮除乾 淨，達到清潔喷頭的目的。 此外，經喷液口 371喷出的液體及經刮板34刮除之 廢液及廢渣會流至盒體31中，並經由與盒體31連接之廢 液管38流至廢液裝置（係設置於第一圖A之基座平台10 下方，未顯示），以供進行廢液處理。 另一方面，前述之喷頭清潔裝置30除應用於立體成 型裝置之外，亦可應用於一般2D列印裝置之喷頭清潔。 11 201036807 Λ 舉例而言，可根據本案構想將習知列印裝置改良成在刮板 對喷頭進行清潔前，先喷出些微液體至喷頭，讓油墨或高 揮發性的墨水潤濕，使刮板清潔喷頭時更加方便容易。 請參閱第二圖C及第二圖D，其中第二圖C為本案喷 頭封存裝置之結構示意圖，第二圖D為第二圖C蓋板分離 之爆炸圖。如圖所示，喷頭封存裝置40包含基座41、滑 座42、承載座43、密封部件44、保濕裝置45及濕度感應 0 器46，其中，滑座42設置於基座41之上，承載座43設 置於滑座42之上，而密封部件44設置於承載座43之上。 承載座43由一承載槽體431及一蓋板432所組成，密封 部件44係容置於承載座43之承載槽體431中，且部分突 出於承載座43之頂表面，其中，承載座43之蓋板具有對 應於密封部件44之開口 433，使密封部件44可穿過開口 433而突出於承載座43之頂表面。密封部件44係用來包 覆密封喷印匣之喷頭，以保持喷頭的濕度，防止膠合劑乾 ❹ 涸而阻塞喷頭之喷嘴。密封部件44之形狀及位置皆係對 應喷印匣之喷頭而設置，故密封部件之數目亦可對應喷印 匣之數目而變化，不限於本實施例所圖示之兩個密封部件 44 ° 為確保密封部件44包覆密封喷頭時之保濕狀態，本 案之噴頭封存裝置40更具有保濕裝置45，其係包含儲水 槽451、抽水管452、喷霧管453及集水管454。儲水槽 451係相鄰於基座41而設置，且透過抽水管452自供水裝 置（係設置於第一圖Α之基座平台10下方，未顯示）輸 12 201036807The forming drying time of Hi Temple increases the time of total forming,

[Embodiment] Some exemplary embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It is to be understood that the present invention is capable of various modifications in the various aspects of the present invention, and the description and illustration are in the nature of 5 201036807 Please refer to FIG. A, which is a perspective structural view of a desktop type body forming apparatus according to a preferred embodiment of the present invention. As shown in the first figure A, the base platform 10 of the desktop stereoscopic molding apparatus 1 of the present invention mainly comprises a printing module 11, a powder supply tank 12 and a construction groove 13, wherein the groove body 130 of the groove 13 is constructed (such as The first figure B) extends downward from the base platform 10 and is partially disposed above the base platform 10. The powder supply tank 12 is configured to provide a construction powder into the construction tank 13, and is printed by the printing module 11 to form a three-dimensional article to be formed by stacking the layers in the construction tank 13q. The inside of the construction groove 13 has a bottom plate 131 (as shown in the first figure B) for carrying the powder and the layered and formed three-dimensional articles, and is fixed on the lifting platform 61 (as shown in the first figure B). It can be lifted and lowered inside the construction tank 13 by the lifting device 60 (as shown in FIG. 3A). In one embodiment, the construction groove 13 is disposed at a central portion of the desktop stereoscopic molding apparatus 1, the printing module 11 is disposed at a left portion of the construction groove 13, and the powder supply groove 12 is disposed at a right portion of the construction groove 13. In this embodiment, the printing module 11 is printed in the direction from the left side to the right side in the X-axis direction, but the actual operation mode is not limited thereto. Please refer to the first figure A, the first figure B and the first figure C. The first picture B is a sectional structure diagram of the printing module, the powder supply tank and the construction groove in the first picture A, and the first picture C is A schematic diagram of powdering for the powder tank to move above the construction tank. The table top three-dimensional forming device 1 of the present invention operates in the following manner: First, the powder supply tank 12 on the right side moves from right to left in the X-axis direction to above the construction groove 13, and is laid on the bottom plate 131 of the construction groove 13. After the powder is completed, the powder supply tank 12 is moved to the right side to be reset, and the powder is placed flattened and flattened by the powder roller 16 of the 6 201036807 provided at the left end of the powder supply tank 12, so that the powder is laid flat in the construction tank. The bottom plate 131 has four (four) surfaces, and excess powder can be pushed into the recovery tank 14 so that it can be recycled and reused. In the embodiment, the desktop stereoscopic molding device of the present invention further comprises a printing and powdering and separating operation device, which comprises a telescopic dustproof sheath 15 connected to the right end of the powder supply tank 12, when When the powder tank 12 moves to the left and is laid on the construction tank 13, the telescopic dustproof sheath 15 is stretched and covered on the entire construction tank 13 at the same time, and the powdered powder is also covered, so as to avoid dust flying. The components on the base platform 10, especially the transmission component, have a dustproof effect, which prevents the flying dust from being attached to the transmission component, thereby causing the influence of the service life and the printing accuracy, and at the same time, the powder supply tank 12 is to be laid. After the powder is completed, the powder is also placed on the construction tank 13 by the cover. By printing the module 11 and printing the printing, the dust can be greatly reduced. The dust is flying differently from the conventional device. Missing. © Referring to FIG. A again, the desktop stereoscopic molding apparatus 1 of the present invention further includes a first transmission component for driving the movement of the powder supply slot 12 in the X direction. The first transmission component comprises a motor 20, a ball lead screw 21, a sleeve 22, a linear slider 23 and a sleeve 24', wherein the sleeve 22 is sleeved on the ball lead screw 21, and the sleeve 24 is sleeved on the linear slider 23 The ball lead screw 21 and the linear slide bar 23 are disposed across the two sides of the powder supply tank 12 and disposed in parallel with each other. As shown in FIG. A, 'the powder supply tank 12 is fixed on a carrier plate 25' and the sleeve 22 and the sleeve 24 are respectively fixedly coupled to the carrier plate 25. Therefore, when the motor 20 drives the ball lead screw 21 to rotate, , 7 201036807 21 on the feed compound, this can be moved to make the desktop move. With the provision of a movable powder supply tank, the molding device 1 achieves a better spatial configuration. After that, the printing die 11 is mixed with the powder and moved to the right side to reset or moves to the right side of the construction tank 13 along with the ink jet column E (3), and utilizes the partial powder laid in the groove 13 The upper part of the hp contains Ο Ο = 'The glue liquid is adhered to the powder and solidified; the movement, in which the transmission mode of the h 4 卩 · U is applied to the general device, so it will not be described here. Subsequently, when the printing operation is completed, the printing module u will move to the left side, and the bottom plate 131 of the construction groove 13 is also controlled by the lifting device and is lowered by Z 2 - the predetermined height can be further performed by the powder supply tank 12 For powder supply _ new laying - layer powder on the powder that has been printed, and enter =--man's printing operation... directly repeat the above process layer (4) to complete the three-dimensional object, that is, the 3D solid model . Referring to the first figure DG, the first figure D is the first structural diagram when the cover body is opened, and the structure is shown in the figure of the yellowing structure 7" ,—®G is a schematic diagram of the structure of the powder feeding tank in the non-dropping state. The inner part of the powder supply tank 12 is provided with a mixing rod i2i, which is made of _ 12 (four) powder, 2 = evenly distributed in the powder supply tank 2. The lion (2) is connected with -, It is used to move the board 8 201036807 piece 124 with a plurality of long slots 125. Please also refer to the first figure F and the figure G, which is a sectional structure diagram for the private slot, as shown in the figure. (4) The bottom of the 12 corresponds to the panel 124. The area is provided with a plurality of openings 1 126. Since the eccentric 123 rotates, the panel 124 will be left and right _, when the plate 124 has J = 125 and the bottom of the powder supply tank 12 When the opening 126f is connected to the tenth position (as shown in FIG. 2), the powder in the powder supply tank 12 can be dropped into the construction groove 13 through the slot 125 and the opening 126 for powder supply; When the slot (2) and the opening 126 are misaligned and not in communication (as shown in the first figure G), the powder will not fall into the construction groove 13, thereby controlling the amount of powder supplied and preventing the powder from being externalized. As shown in FIG. E, the slots 125 provided in the plate member 124 are horizontally and separately spaced from each other, and the openings 126 provided at the bottom of the powder supply slot 12 are mutually spaced. The same is also horizontal and separate, so that the powder can be powdered on the construction tank 13 in a segmented manner, so that the spreading density on the construction tank 13 is uniform, and the conventional technique can be solved once the powder supply is started. 0 for all the amount of powder 'causes the weight of the front and rear sections to be unevenly formed and the excess powder to be pushed into the recovery tank 14 due to the weight and pushing at the start of pushing the powder. After the printing is completed, it is necessary to wait for the molding drying time. [The conventional technology is about to wait three minutes for each powder to be dried. The powder drying time is greatly increased. The total molding time is greatly increased. Therefore, in order to achieve a faster drying speed, the table type of the case is obtained. The three-dimensional forming device 1 further comprises a heating assembly 17 (shown in FIG.
