Description

本発明は、３次元積層造形装置に関し、詳しくは、造形材を積層して形成される造形層に３次元形状の断面データをもとに断面形状の硬化領域を形成して三次元形状を造形する３次元積層造形装置に関する。   The present invention relates to a three-dimensional additive manufacturing apparatus, and more specifically, a three-dimensional shape is formed by forming a cross-sectional cured region based on cross-sectional data of a three-dimensional shape on a modeling layer formed by stacking modeling materials. The present invention relates to a three-dimensional additive manufacturing apparatus.

従来の３次元積層造形装置としては、光造形方法や、粉体を積層して造形する方法や、シート材を積層してカットする方法等、いろいろな方法が提案されて公知である。
例えば、造形範囲全体の１層分の造形層を形成して、その造形層を選択的に硬化させて造形を行う３次元積層造形方法としては、上下に移動が可能な造形テーブル上に造形材を供給して造形層を形成し、その造形層に３次元形状の断面硬化パターンを形成して、そして、造形テーブルを積層ピッチ分下降させて次の造形層の形成と断面硬化パターン形成を繰り返して造形するものであった。
造形層を形成する際に、光造形方法では、スキージと往復運動するリコータと呼ばれる供給装置で光硬化樹脂を１層分コートする。
粉体造形方法では、ロールやスキージ等の供給装置を往復動作させて粉体の層を形成している。
又、シート造形方法についても、供給したシートを１層下のシートに接着する際に往復動作するロール等で接着を行っていた。
これ等の従来方法では、供給装置を往復動作させて、造形層を形成するため、加減速、動作方向の転換等が必要で高速化には限界があった。
又、造形層を形成した後に、断面パターンを形成する際に、これら等の供給装置を退避する必要があり、退避時間も必要になっていた。 As a conventional three-dimensional layered modeling apparatus, various methods such as an optical modeling method, a method of stacking and modeling powders, and a method of stacking and cutting sheet materials are proposed and known.
For example, as a three-dimensional layered modeling method in which a modeling layer for one layer of the entire modeling range is formed, and the modeling layer is selectively cured, modeling is performed on a modeling table that can be moved up and down. Forming a modeling layer, forming a three-dimensional cross-section hardening pattern on the modeling layer, and then lowering the modeling table by the stacking pitch to repeat the formation of the next modeling layer and the cross-section hardening pattern formation It was something to model.
When forming a modeling layer, in the optical modeling method, one layer of photo-curing resin is coated with a supply device called a recoater that reciprocates with a squeegee.
In the powder modeling method, a powder layer is formed by reciprocating a supply device such as a roll or a squeegee.
Moreover, also about the sheet | seat shaping | molding method, when the supplied sheet | seat was adhere | attached on the sheet | seat of the lower layer, it was adhere | attached with the roll etc. which reciprocate.
In these conventional methods, since the forming device is formed by reciprocating the supply device, acceleration / deceleration, change of the operation direction, and the like are necessary, and speeding up is limited.
Moreover, after forming a modeling layer, when forming a cross-sectional pattern, it was necessary to evacuate these supply apparatuses, and the evacuation time was also required.

そこで、光硬化性の液を上塗手段が上塗りしつつ前進する時、上塗手段の後方直後の上塗りされた液面を光で走査して光硬化性の液を硬化させることにより、光硬化性の液の上塗りと断面パターンの形成である光走査が並行して行えるため、造形時間を短縮化することも公知である（特許文献１を参照）。
この例は、液体の造形材の例であるが、造形材が液体以外の場合でも造形層形成の直後に断面パターンの形成を追いかけるように行えば、造形時間の短縮化が可能である。
然し、上塗りと光走査がほぼ同時に行われるため工程がオーバーラップした分だけの時間の短縮化は出来るが、上塗手段と光走査手段が元の位置に戻るための動作が必要であるだけでなく、往復動作をする必要があり、造形時の加減速、動作方向の転換や停止にどうしても長時間を必要としていた。
又、平板状の光透過部を有し、水平面に沿って駆動可能に支持されたステージと、ステージを水平面に沿って駆動する水平駆動機構と、ステージの光透過部の表面に、未硬化の光硬化性樹脂を供給するための樹脂供給装置と、ステージの下方位置に、ステージの裏面に向けて配置され、前記等高線データに応じた領域に光を照射する光照射装置と、ステージの上方位置に、光照射装置と対向させて配置され、昇降可能に支持されたテーブル等で構成されて、樹脂供給装置から樹脂供給をステージの回転中に行って、積層工程と別のステーションで行うことで、樹脂供給のための往復運動を無くし、テーブルの上下動のストロークを短くして造形工程の高速化を行うことも公知である（特許文献２を参照）。
然し、樹脂供給時の往復動作は無くなっているが、積層用のテーブル位置が固定で上下動しかしないため、回転ステージを停止してからしか積層動作のテーブルの上下動の動作が出来ないので、回転ステージは間欠動作となり、造形時の加減速、動作方向の転換や停止等にどうしても長時間を必要として、造形時間が長くなっていた。
従って、従来の３次元積層造形装置は、造形材の供給や造形層の断面パターンの形成等が往復動作や間欠動作で行われて、造形時の加減速、動作方向の転換、停止や退避等に長時間を必要として、造形時間を短縮化することが困難で、造形時間が長くなると言う不具合が生じていた。
特開２０００−２２５６４７公報 特開２００１−３４７５７２公報 Therefore, when the photocoating liquid moves forward while the overcoating means overcoats, the photocurable liquid is scanned by light over the surface of the overcoated liquid immediately after the overcoating means to cure the photocurable liquid. It is also known to shorten the modeling time because the liquid overcoating and the optical scanning that is the formation of the cross-sectional pattern can be performed in parallel (see Patent Document 1).
Although this example is an example of a liquid modeling material, even when the modeling material is other than liquid, if the cross-sectional pattern formation is followed immediately after the modeling layer formation, the modeling time can be shortened.
However, since the overcoating and the optical scanning are performed almost simultaneously, the time can be shortened by the overlap of the processes, but not only the operation for returning the overcoating means and the optical scanning means to the original position is necessary. It was necessary to reciprocate, and it took a long time for acceleration / deceleration at the time of modeling, change of operation direction and stop.
In addition, a stage having a flat light transmitting portion, supported so as to be driven along a horizontal plane, a horizontal drive mechanism for driving the stage along the horizontal plane, and an uncured surface on the surface of the light transmitting portion of the stage A resin supply device for supplying a photocurable resin, a light irradiation device that is arranged at a lower position of the stage toward the back surface of the stage, and irradiates light to an area corresponding to the contour data, and an upper position of the stage In addition, it is composed of a table or the like that is arranged facing the light irradiation device and supported so as to be movable up and down, and the resin is supplied from the resin supply device while the stage is rotating, and is performed at a station separate from the laminating step. It is also known to speed up the modeling process by eliminating the reciprocating motion for resin supply and shortening the vertical movement stroke of the table (see Patent Document 2).
However, although the reciprocating operation at the time of resin supply is gone, the table position for stacking is fixed and only moves up and down, so the table can be moved up and down only after the rotary stage is stopped. The rotating stage is intermittently operated, and it takes a long time for acceleration / deceleration at the time of modeling, change of operation direction, stop, etc., and the modeling time is long.
Therefore, in the conventional three-dimensional additive manufacturing apparatus, the supply of the modeling material, the formation of the cross-sectional pattern of the modeling layer, and the like are performed by a reciprocating operation or an intermittent operation. It takes a long time, and it is difficult to shorten the modeling time, resulting in a problem that the modeling time becomes long.
