<h3>PrusaSlicer マニュアルへようこそ</h3>
<p>PrusaSlicer (旧称：Slic3r Prusa EditionまたはSlic3r PE) は、オープンソースプロジェクト<strong><a href="https://slic3r.org/">Slic3r</a></strong> をベースにした自社開発のスライサーソフトウェアです。PrusaSlicerは、オープンソースで、機能が豊富で、また頻繁に更新されているツールです。</p>
<p>PrusaSlicerは、<a>Windows, Mac and Linux</a> に対応しています。</p>
<h3>歴史</h3>
<p>Slic3rプロジェクトは、<strong>Alessandro Ranellucci</strong> のリーダーシップのもと、成長を続ける3Dプリント技術にオープンソースのスライサーを提供する取り組みとして、2011年にRepRapコミュニティ内で誕生しました。Slic3rはすぐにユーザーの間に広まり、Josef Prusaが Original Prusa プリンター用の主要なスライシングソフトウェアを探していたとき、このSlic3r が選ばれました。Slic3r はオープンソースで、現在もそうですが、当時非常にパワフルなソフトウェアでした。</p>
<p style="text-align: center;"><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.helpdev.prusa3d.com/en/wp-content/uploads/jo_and_allesandro.png" sizes="100vw" srcset="http://help.prusa3d.com/wp-content/uploads/jo_and_allesandro-300x170.png 300w, /wp-content/uploads/jo_and_allesandro-600x341.png 600w, /wp-content/uploads/jo_and_allesandro-768x436.png 768w, /wp-content/uploads/jo_and_allesandro-800x454.png 800w" alt="" width="421" height="239" /><em>Jo and Alessandro in 2012 (<a href="https://www.youtube.com/watch?v=Tuxg2L7r1oI">video interview</a>)</em></p>
<p>しかし、Prusa Researchが非常に非常に早いスピードで成長するにつれ、スライシングソフトウェアの開発をより柔軟に行う必要がありました。ソフトウェアに変更を加える必要があり、その変更は早急に行われなければならず、また、より多くの機能を追加する必要もありました。この時点で、切り離されたオリジナルのSlic3rチームとの協力関係は維持できず、結局は、私たちでオリジナルのSlic3rプロジェクトのフォークを設立することにしました。</p>
<p>Slic3r Prusa Editionは、2016年11月に発売されました - 発売の詳細は<a href="https://blog.prusaprinters.org/introducing-slic3r-prusa-edition/">こちら</a>をご覧ください。専任のSlic3r PE開発者チームが設立され、新機能がどんどん追加されていきました。これらの変化は2019年5月に結実し、UIを大幅に刷新した新バージョンを<a href="https://blog.prusaprinters.org/prusaslicer-2-release/">PrusaSlicer2.0</a>という新しい名前でリリースしました。</p>
<p>なぜ名前を変えたのか？まず第一に、以前の名前は本当に紛らわしいものでした。自分たちの資料でも「PE」という接尾語をつけないことが多く、コミュニティでは Slic3r と Slic3r PE をほぼ同じ意味で使っていました。新しいユーザーは、Slic3r を誤ってダウンロードし、「3D Printing Handbook」に掲載されているスクリーンショットとは違って見えることや、自分のPrusaプリンタ用に設定されていないことを不思議に思うかもしれません。オリジナルの Slic3r について言えば、Slic3r PE はアップデートのたびに、オリジナルのコードからどんどん離れていきました。私たちは Perl のソースコードをすべて C++ に書き換え、特に2.0のアップデートでは、あまりにも多くの違いがあったため、名前をより明確にすることが適切だと考えました。</p>
<p>もちろん、オープンソースであり、 <a href="https://github.com/prusa3d/PrusaSlicer">GitHub</a> ですべてを見ることができます。そして、私たちのスライサーが <strong><a href="https://slic3r.org/">Alessandro Ranellucci</a></strong> によって書かれたオリジナルのプロジェクトをベースにしていることを、私たちは今でも誇りに思っています。現在、両プロジェクトは楽しく共存しており、新機能は頻繁にマージされています。</p>


概要情報

<p dir="ltr">インフィルの主な目的は、トップレイヤーの下を支持することです。そうしないと、トップレイヤーは何もないところにブリッジすることになります。 インフィルは、プリントスピード、強度、フィラメント消費量、さらにはプリントの外観にも影響します。</p>
<div class="note-callout">一部のオプションは、<a href="http://help.prusa3d.com/ja/article/simple-advanced-expert-modes_1765">Expert mode</a> を選択した場合にのみ表示されます。</div>
<h3>インフィル(充填密度)</h3>
<p>ほとんどのモデルは、10～15％のインフィルで十分です。 上部が徐々に閉じていくモデルでは、中空（0％のインフィル）でもプリントできますが、通常はお勧めしません。 モデルに重さが必要なときや、より高い耐圧縮性またはより高い剛性が必要な場合は、インフィル値を増やすことで対応できます。 ただし、30％を超えるインフィルが必要になることはめったにありません。 最後に、100％のインフィルでモデルをプリントすると、インフィルパターンが強制的に直線になります。 100％のインフィルは、プリントしたモデルの外観に悪影響を与えることがありますので注意してください。</p>
<div class="tip-callout"><strong>モデルの強度向上</strong><br />
モデルの強度は、主に<strong>外周の周回数で決まります(インフィルではありません)</strong>。 より強いプリント品が必要なときは、外周の数を増やします。 とは言うものの、インフィルを増やすと耐圧縮性が向上します。</div>
<h3>インフィルパターン</h3>
<p>PrusaSlicerは、選択可能な多くのインフィルパターンを提供します。 インフィルパターンを選択するとき、考慮すべき主な事項は次のとおりです:</p>
<ul>
<li>プリントスピード</li>
<li>材料使用量あたりの密度 (少ない材料でトップレイヤーをしっかりとサポートする)</li>
<li>仕上がりの外観</li>
<li>トップレイヤーをサポートする</li>
<li>柔軟性 (TPU/TPE材のプリント)</li>
</ul>
<h4>ジャイロイドインフィル</h4>
<p>ジャイロイドは、ベストなオールラウンドインフィルの1つです。</p>
<ul>
<li>3D構造です -  <strong>全ての方向で一定の強度</strong>になります。</li>
<li>この構造はかなり <strong>速く</strong> プリントできます。</li>
<li> 同一レイヤーでパスが<strong>交差しません</strong> 。</li>
<li> <strong>強度/重さについて良好なバランス</strong>になります</li>
<li>(あくまでも主観ですが) <strong>結構きれいに</strong>仕上がります</li>
</ul>
<h3>トップ塗りつぶしパターン</h3>
<p>最上層レイヤーにのみ適用され、その下の隣接するソリッドレイヤーなどには影響しないカスタムインフィルパターンが選択できます。&nbsp;</p>
<h3>ボトム塗りつぶしパターン</h3>
<p>上部の隣接するソリッドレイヤーではなく、最下層のレイヤーにのみ適用されるカスタムインフィルパターンが選択できます。</p>
<h3>インフィルをXレイヤー毎に結合する</h3>
<p>プリント品質を犠牲にせず速くプリントするために、外周とは異なる積層高さでのインフィルが形成されます。<br />
例: プリントレイヤーピッチが0.1mmで、インフィルを3レイヤー毎に結合するという指定をすると、インフィルは0.3mmピッチでプリントされます。</p>
<div class="note-callout">最大の積層高さは、ノズルの直径によって決まります（最大値はおよそノズル直径の80％）。0.4mmノズルを使用しているときに、外周の積層高さが0.3mm設定で結合を2レイヤー毎と設定しようとすると、制限の0.32mm以上になってしまうので、実際には結合しなくなります。</div>
<div><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="http://help.prusa3d.com/wp-content/uploads/combine_every-01.png" sizes="100vw" srcset="http://help.prusa3d.com/wp-content/uploads/combine_every-01-300x169.png 300w, http://help.prusa3d.com/wp-content/uploads/combine_every-01-600x337.png 600w, http://help.prusa3d.com/wp-content/uploads/combine_every-01-768x432.png 768w, http://help.prusa3d.com/wp-content/uploads/combine_every-01-800x450.png 800w" alt="" width="699" height="393"></div>
<div style="text-align: center;"><em>壁の断面拡大イメージ：インフィル(グレー)は外周レイヤー(オレンジ)の高さの2倍でプリントされています</em></div>
<h3>必要な場合のみインフィルを付ける</h3>
<p>このオプションは、インフィルが内部サポートのように振る舞います。上部でサポートが必要な領域のみ、その下にインフィルパターンを生成します。 このオプションを有効にすると、Gコードの生成が遅くなります（追加のオーバーハング計算を行うため）。 さらに、一部の領域ではインフィルが外周パターンから離れることがあるため、このオプションを使ったときはツールパスを入念にチェックすることが必要です。</p>
<div class="note-callout">このオプションは、サポートの <a href="http://help.prusa3d.com/ja/article/support-material_1698#overhang-threshold">オーバーハングのしきい値</a>設定が反映されません。</div>
<p style="text-align: center;"><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="http://help.prusa3d.com/wp-content/uploads/infill_only_where_needed.png" sizes="100vw" srcset="http://help.prusa3d.com/wp-content/uploads/infill_only_where_needed-300x195.png 300w, http://help.prusa3d.com/wp-content/uploads/infill_only_where_needed-600x391.png 600w, http://help.prusa3d.com/wp-content/uploads/infill_only_where_needed-768x500.png 768w, http://help.prusa3d.com/wp-content/uploads/infill_only_where_needed-800x521.png 800w" alt="" width="654" height="426"><em>必要な場合のみインフィルを付けるオプションを有効にした場合の球</em></p>
<h3>ソリッドインフィルを各Xレイヤー毎に</h3>
<p>この機能により、任意のレイヤー数ごとに強制的にソリッドレイヤーを作成することができます。これは、プリントパーツの強度を上げるのに役立ちますが、それが目的でしたら、外周の数やインフィルパターンの割合を増やすなどの方法を推奨します。このオプションの他の用途としては、断熱性を高める目的で内部に個別のセルを作りたいときなどがあります。</p>
<p><strong>0で無効になります。</strong></p>
<h3>塗りつぶし角</h3>
<p>デフォルトのインフィル角度。 クロスハッチングは、一部の塗りつぶしパターンで適用されます。</p>
<div class="note-callout"><strong>ブリッジ領域は</strong> PrusaSlicerが最適な方向を自動で探すため、この設定はブリッジには影響しません。</div>
<h3>ソリッドインフィル領域のしきい値</h3>
<p>指定したしきい値よりも面積が小さい領域が、強制的にソリッドインフィルになります。</p>
<p><strong>0で無効になります。</strong></p>
<p style="text-align: center;"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="http://help.prusa3d.com/wp-content/uploads/solid_infill_threshold.png" sizes="100vw" srcset="http://help.prusa3d.com/wp-content/uploads/solid_infill_threshold-300x92.png 300w, http://help.prusa3d.com/wp-content/uploads/solid_infill_threshold-600x184.png 600w, http://help.prusa3d.com/wp-content/uploads/solid_infill_threshold-768x236.png 768w, http://help.prusa3d.com/wp-content/uploads/solid_infill_threshold-800x246.png 800w" alt=""><em>(左)しきい値0、(中央)15、(右)100</em></p>

QRエラーコード

<h3>What happened?</h3>
<p>The printer is displaying the message: <strong>The Ambient temperature/UV LED temperature sensor failed.</strong></p>
<p>Error name: Temperature sensor failed</p>
<p>Error code: #10205</p>
<p>The SL1 has several sensors measuring the temperature of various parts and components of the printer. If a wire has been disconnected or damaged, or the sensor itself has been damaged it can produce this error.</p>
<h3>How to fix it?</h3>
<h4>Accessing the mainboard</h4>
<p>First, make sure the plug of the sensor has not detached from the A64 mainboard. To access the mainboard:</p>
<ol>
<li>Remove the 4 screws on the left and right-hand side of the printer.</li>

<h3>What happened?</h3>
<p>The printer is displaying the message: <strong>The update of the firmware failed! Restart the printer and try again.</strong></p>
<p>Error name: Firmware update failed</p>
<p>Error code: #10534</p>
<h3>How to fix it?</h3>
<p>The flashing of the firmware failed. There can be several reasons for this:</p>
<ul>
<li>The firmware file is corrupted or the USB stick was removed during the flashing process.</li>
<li>The printer lost its network connection during an OTA update.</li>
</ul>
<p>If the previous points check out then look into:</p>
<ul>
<li>The firmware you are flashing is of a version too far ahead of the existing firmware. Try to flash the firmware version after the one you have. For example, do not update directly from 1.2.0 to 1.4.0, without updating to 1.3.0 first.</li>
</ul>
<p>For older versions of the firmware, see the <a href="https://www.prusa3d.com/drivers/firmware-changelog/#sl1">firmware changelog for older firmware</a>.</p>

Cannot get update channel #10514 (SL1)

<h3>What happened?</h3>
<p>The printer is displaying the message: <strong>The printer is not calibrated. Please run the Wizard first</strong>.</p>
<p>Error name: Not mechanically calibrated</p>
<p>Error code: #10113</p>
<p>Issued when the printer has not been calibrated before a print.</p>
<h3>How to fix it?</h3>
<p>Go in the printer menu to <em>LCD menu -&gt; Settings -&gt; Calibration -&gt; Printer Calibration</em>. Follow the instructions on the screen, and remember that you can swipe the screen to see example pictures of each step of the calibration.</p>
<p></p>


Calibration error #10113 (SL1/SL1S)

<h3>What happened?</h3>
<p>The printer is displaying the message: <strong>Requested intensity cannot be reached by min. allowed PWM.</strong></p>
<p>Error name: UV intensity too high&nbsp;</p>
<p>Error code: #10317</p>
<p>The most probable reason for this error is either the print display or UV LED set. Either the LEDs produce too much light, or the display is not blocking enough light.</p>
<h3>How to fix it?</h3>
<h4>Faulty print display or UV LED panel</h4>
<p>Check whether the UV panel and LCD screen work as intended – Run the Display test, found at <em>Settings -&gt; Calibration -&gt; Display test</em> (purple square)<em>.</em> Follow the onscreen instructions.</p>

<p>Check if the logo appears on the display as below. If there are "holes" in the image, the print display must be replaced.</p>
<p>To do so, remove the black cover secured by eight screws, then inspect the cable leading from the exposition (print) display. You can carefully disconnect and reconnect the cable header from the mainboard to ensure that it is seated correctly.</p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/testLCDSl1.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/testLCDSl1-300x169.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/testLCDSl1-600x338.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/testLCDSl1-768x432.jpg 768w" alt=""></p>
<p>If it remains completely dark, it may have a faulty UV LED panel. Check its wiring by unplugging it and plugging it back in, making sure the connector is seated properly. Test the display again and if it still does not work it will have to be replaced.</p>

UV intensity too high #10317 (SL1/SL1S)

<h3>What happened?</h3>
<p>The printer is displaying the message: <strong>(sensor)s not in range! Measured temperature: (temperature). Keep the printer out of direct sunlight at room temperature (18 - 32 °C).</strong></p>
<p>Error name: Temp. out of range</p>
<p>Error code: #10208</p>
<h3>How to fix it?</h3>
<p>The printer has a set working temperature between 18 - 32 °C (64 - 89 °F), to ensure smooth operation. Direct sunlight or a cold garage is not ideal. Try to move the printer to a more stable indoor environment, let the temperature equalize over 30 minutes to 1 hour, and try again.</p>
<p>If it persists, it indicates an issue with a temperature sensor, but you should then receive other errors.</p>
<p></p>


Temperature out of range #10208 (SL1/SL1S)

<h3>What happened?</h3>
<p>The printer is displaying the message: <strong>The printer is not connected to the internet, please check the connection in the Settings.</strong></p>
<p>Error name: Not connected to network</p>
<p>Error code: #10402</p>
<h3>How to fix it?</h3>
<p>There are two ways to connect the SL1 to the internet. You can use a standard RJ-45 ethernet cable. Connect it to your router, and the printer should obtain an IP address automatically - however, this depends on your network configuration. Since every network is different, please refer to your router’s instructions or your provider’s tech support in case you run into trouble. To check whether the connection has been successfully created, go to Main Menu - Settings - Network.</p>
<p>It is also possible to use the built-in Wi-fi network card compatible with 2.4GHz networks. To open the Wi-Fi network browser, go to Settings - Network. A list of all available networks will be displayed. Select your Wi-Fi network and connect to it by typing your password using the on-screen touch keyboard. You can connect a USB keyboard to the front USB port in case the on-screen keyboard is too small.</p>
<p>Since every network is different, we cannot provide exact instructions on how to connect to your wireless/wired network. If you encounter any trouble, please refer to your router’s manual, or contact your internet provider’s tech support. The quality of your wireless connection depends on many factors - such as the type/configuration of the router, the distance of the printer from the router, or wireless (EMI) interference in your area.</p>
<p></p>


Not connected to network #10402 (SL1/SL1S)

<h3>What happened?</h3>
<p>The printer is displaying the message: <strong>This project was prepared for a different printer</strong>.</p>
<p>Error name: Wrong printer model</p>
<p>Error code: #10544&nbsp;</p>
<p>This error informs that the project to be printed has not been sliced for the same printer that you are trying to print it on. For example, you have the Original Prusa SL1S Speed and the model has been sliced for the Original Prusa SL1.</p>
<h3>How to fix it?</h3>
<p>Open the project in Prusa Slicer and select the correct printer on the right sidebar. In case you cannot see your printer, go in PrusaSlicer to <em>Configuration -&gt; Configuration Wizard -&gt; Prusa MSLA</em>, and make sure that your printer is selected.</p>

<p>The printer is displaying the message: <strong>The project must have at least one layer</strong>.</p>
<p>Error name: Not enough layers</p>
<p>Error code: #10540&nbsp;</p>
<p>This error happens when the project to be printed does not have enough layers to be printed.</p>
<h3>How to fix it?</h3>

<h3>What happened?</h3>
<p>The printer is displaying the message <strong>The ambient temperature is too low, the print can continue, but it might fail.</strong></p>
<p>Error name: Ambient temp. too cold</p>
<p>Error code: #10703</p>

Ambient temperature too cold #10703 (SL1/SL1S)

<h3>What happened?</h3>
<p>The printer is displaying the message: <strong>Data is from unknown UV LED sensor!</strong></p>
<p>Error name: UV data error</p>
<p>Error code: #10533</p>
<p>After calibration using the UV calibrator, the data was decoded successfully, but it was not possible to check its consistency. This is caused by using an unknown/unsupported calibrator.</p>
<h3>How to fix it?</h3>
<p>If you used the calibrator supplied by Prusa Research, please contact customer support.</p>
<p>If a third-party calibrator has been used you will need to purchase an Original Prusa UV calibrator from our e-shop.</p>
