HT90

<p>オリジナルPrusaマグネット式ヒートベッドは、取り外し可能な両面フレキシブルスプリングスチールシートを保持するように設計されており、プリントされたオブジェクトをプリント表面から簡単に取り外すことができます。</p>
<p><strong>4種類の異なるシートを提供しています</strong>。それぞれ異なる強度と特性を持っています。</p>
<ul>
<li><strong>スムース</strong>シートは、ほとんどのフィラメントと形状に優れた接着性を提供します。実際、TPUやPETGなどの一部のフィラメントは<strong>過剰に</strong>接着し、取り外す際にシートを<strong>損傷する可能性があります</strong>。</li>
<li>粉体塗装<strong>テクスチャー</strong>シートは、PETGやその他の高接着フィラメントを使用する生産環境向けです。</li>
<li><strong>サテン</strong>シートは、テクスチャーと特性の両面でスムースシートとテクスチャーシートの中間に位置します。</li>
<li><strong>PAナイロン</strong>シートは、標準のPEIシートへの接着が一般的に非常に悪いポリアミド（ナイロン）のプリント用に特別に設計されています。</li>
</ul>

<h3>HT90スチールシート</h3>
<p>Prusa Pro HT90は3種類のプリントシートを使用できます。<strong>テクスチャー</strong>、<strong>サテン</strong>、<strong>PAナイロン</strong>です。</p>
<h3><strong>一般情報</strong></h3>
<p>取り外し可能なスプリングスチールシートは、ヒートベッドの底面に接着された複数の磁石によって所定の位置に保持されます。MKシリーズ、MINI/+、XL、およびHT90では、ヒートベッドの上部にスプリングスチールシートの<span style="color: #e67e23;"><strong>切り欠き</strong></span>と完全に一致する2つのピンがあります。</p>
<p><em>スチールシートをヒートベッドに置く前に、ヒートベッドがきれいで、フィラメントの破片がないことを確認してください。</em></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/prusuki/prusuki-images/aligning-pins.jpg" /></p>

<div class="note-callout">MKシリーズとMINI/+では、切り欠きの反対側にあるスチールシートの2つの穴を無視してください。これらは製造プロセスによるものであり、シートをベッドに合わせるためのものではありません。</div>
<h3>スチールシートプロファイル（MK2/S、MK2.5/S、MK3/S/+、MK3.5/S、MINI/+）</h3>
<p><a href="http://help.prusa3d.com/ja/article/loadcell-mk4-s-mk3-9-s-xl_401253">ロードセル</a>を装備していない<strong>プリンター</strong>の場合、各シートの厚さが若干異なるため、異なるLive-Z値が必要です。複数の異なるシートを使用している場合、各シートの値はスチールシートプロファイルに保存できます。詳細については、<a href="http://help.prusa3d.com/ja/article/steel-sheet-profiles_1955">スチールシートプロファイル</a>の記事をご覧ください。</p>
<h3>プリントの取り外し</h3>
<p>プリントされたオブジェクトをプリント表面から取り外すには、常にスチールシートが<strong>室温まで冷めるのを待ってください</strong>。その後、シートを内側と外側に<strong>曲げる</strong>ことで取り外すことができますが、シートの損傷を避けるためにヘラを使用する必要がある場合があります。<strong>PETG、ASA、ABS、PCブレンドなどの材料や、大きな最初のレイヤー表面を持つプリントの場合、グルースティックの形での分離層が必要になる場合があります。</strong></p>

<div>
<p>冷却後でもモデルの取り外しに苦労している場合や、取り外し中に表面が損傷した場合（表面の一部が剥がれたり亀裂が入ったりした場合）、このタイプのプリントシートに適していないフィラメントタイプを使用しているか、表面が正しく準備されていない可能性があります。フィラメントとプリントシートの互換性および表面準備については、<a href="https://help.prusa3d.com/materials">材料表</a>をご覧ください。</p>
<p>モデルの取り外しを助けるためにヘラを使用する場合は、シート表面への損傷を避けるよう注意してください。可能な限り、平らな表面でモデルの下を掘るのではなく、シートを少し曲げてモデルの下にヘラを挿入してください。</p>
<p>プリント表面から離れないしつこいプリントの場合、ヒートベッドを数分間再加熱し（元のプリント温度まで）、再び冷却させることができます。これは、プリント表面に過度に固着したプリントの取り外しに役立つ場合があります。</p>
</div>
<div class="warning-callout">プリントシート（サテン、スムース、テクスチャーなど）などの消耗品は、コーティングが時間とともに劣化するため、保証の対象外です。材料または製造上の欠陥による故障でない限り、傷、へこみ、亀裂、その他の外観上の損傷を含むがこれらに限定されない外観上の損傷も保証の対象外です。到着時に欠陥のあるシートのみが保証の対象となります。</div>

<h4>スムースPEIシート</h4>
<p>このシートの両面は、滑らかなPEIプラスチックで作られたステッカーで覆われています。これは、以前のMK2Sプリンターで使用されていた時間テスト済みの表面タイプと同じです。プリント面に触れる面積が小さいプリントや鋭い角を持つプリントは、スムーススプリングスチールシート上でプリントする際に剥がれにくくなります。一部のユーザーは、プリントの底面が滑らかで光沢があることも好んでいます。<strong>スムースシートの詳細と考慮事項については、<a href="http://help.prusa3d.com/ja/article/smooth-steel-sheet_196550">スムーススチールシート</a>をご覧ください。</strong></p>
<h4>粉体塗装テクスチャーシート</h4>
<p>このシートの表面は、完璧な接着を確保するために特殊なポリマー（Ultem）でコーティングされています。粉体塗装スチールシートは、滑らかな表面に過度に接着する傾向のあるPETG、CPE、Flexfill（TPU）などの材料でオブジェクトをプリントする際に適していますが、テクスチャー表面からはより簡単に取り外すことができます。<strong>テクスチャーシートの詳細と考慮事項については、<a href="http://help.prusa3d.com/ja/article/textured-steel-sheet_196534">テクスチャースチールシート</a>をご覧ください。</strong></p>
<h4>サテンシート</h4>
<p>サテンシートは、プリントシートのラインナップをさらに拡張します。軽くテクスチャー加工されたマット仕上げの粉体塗装表面は、最適な接着レベルを提供し、一般的および一般的でないフィラメントの幅広い範囲と完全に互換性があります。<strong>サテンシートの詳細と考慮事項については、<a href="http://help.prusa3d.com/ja/article/satin-steel-sheet_196526">サテンスチールシート</a>をご覧ください。</strong></p>
<h4>PAナイロンシート</h4>
<p>特殊なPAナイロンシートは、標準のPEIシートへの接着が一般的に非常に悪いポリアミド（ナイロン）をプリントするために作られています。このシートは、PEI表面を持つサテンスチールシートに似たマットテクスチャーで提供されます。このシートはほとんどのポリアミドとPETGに対応していますが、他の材料は接着が不十分な可能性があるため、標準のPEIシートでプリントする必要があります。<strong>PAナイロンシートの詳細と考慮事項については、<a href="http://help.prusa3d.com/ja/article/special-pa-nylon-steel-sheet_341570">PAナイロンシート</a>をご覧ください。</strong></p>
<h3>オブジェクトが密着しない</h3>
<p>プリント表面が完全にきれいで、スチールシートタイプのガイドラインに従って拭いてすべての油脂が除去されており、ファーストレイヤーの高さが完璧に設定されているにもかかわらず、プリントオブジェクトがシート表面に確実に接着しない場合は、<a href="http://help.prusa3d.com/ja/article/first-layer-issues_1804">1層目の問題</a>をチェックしてください。</p>


柔軟性のあるスチールシート(ガイドポスト)

<p>PrusaSlicerでは、カスタムSTLを選択し、それをベッドモデルとして使用することができます。</p>
<p>プリンタセッテイタブ-一般-ベッド形状から、モデルセクションのLoad...を使用することで割り当てが可能です。</p>
<p>Printerプリセットを保存しておけば、このカスタムモデルを選択するたびに自動的に読み込まれます。</p>
<p><img decoding="async" src="http://help.prusa3d.com/wp-content/uploads/bed_model_slicer.png" sizes="100vw" srcset="http://help.prusa3d.com/wp-content/uploads/bed_model_slicer-600x327.png 600w, http://help.prusa3d.com/wp-content/uploads/bed_model_slicer-800x437.png 800w, http://help.prusa3d.com/wp-content/uploads/bed_model_slicer-300x164.png 300w, http://help.prusa3d.com/wp-content/uploads/bed_model_slicer-768x419.png 768w, http://help.prusa3d.com/wp-content/uploads/bed_model_slicer-1536x838.png 1536w" alt="" /></p>
<h3>原点位置について</h3>
<p>モデルの原点（座標x:0, y:0, z:0の点）の位置は、プリントベッドエリアの真ん中である必要があります。カスタムモデルを読み込んで、位置がずれて表示される場合は、原点が正しく設定されていない可能性があります。</p>
<p>原点位置を編集するには、Blender などのほとんどの 3D プログラムを使用することができます。例えば、反対側の角にある2つの頂点を選択し、(F3) Snap cursor to selected を使って、3Dカーソルを希望の原点位置に配置します。次にモデルを右クリックして、「原点を設定」-「原点を3Dカーソルに」を選びます。</p>
<p>次に、カーソルをワールド原点に戻します（F3)Snap Cursor to World Origin）。そして最後に、プリントベッドモデルを選択した状態で、(F3) Snap Selection to Cursor を選びます。</p>
<p>これでSTLのエクスポート（File-Export-STL-Tick "Selection only"）ができるようになりました。</p>

<h3>ポリゴン数</h3>
<p>ポリゴン数はなるべく少なくしてください。プリントベッドモデルはほぼ常時表示されているため、ポリゴン数が多いと端末に余計な負荷がかかります。</p>

</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
<ol start="8">
<li>After a successful connection, the first image in Connect will be displayed. The green LED on the camera will blink slowly, showing that it is connected.</li>
<li>The camera will automatically update after connecting to the Internet for the first time. The camera will play a tone after a successful update. You can then start using your Buddy3D camera.</li>
</ol>

<h3>Best use</h3>
<p>Lightweight and strong components in aerospace, engine parts and coolers in automotive, medical implants and tools, functional parts of machinery, valves, and pipes.</p>
<h3>Tips for successful printing</h3>
<p>It is essential to keep the filament dry, otherwise, its mechanical properties will significantly deteriorate. PEEK-CF is extremely hygroscopic and begins to absorb moisture from the air within 10 minutes, affecting the resulting quality and strength. Therefore, we recommend drying the filament for at least 4 hours at 130°C before printing and using a dry box (like the <a href="http://help.prusa3d.com/ja/article/prusa-pro-filament-drybox_725964">Prusa Pro Filament Drybox</a>).</p>
<h3>Heated chamber</h3>
<p>An actively heated chamber is necessary to print this material with a temperature of 85°C or higher. A heated chamber is essential for printing high-temperature materials in FFF, due to several reasons:</p>
<ul>
<li><strong>Prevents deformation: </strong>Maintains stable temperatures to reduce deformation and cracking.</li>
<li><strong>Improves layer adhesion:</strong> Supports stronger connections between layers.</li>
<li><strong>Preserves the properties of the material: </strong>Ensures proper crystallization and strength of the material.</li>
<li><strong>Prevents clogging:</strong> Prevents premature cooling of fibers and prevents problems with extrusion.</li>
<li><strong>Improves accuracy:</strong> Reduces thermal expansion and improves dimensional accuracy.</li>
</ul>
<h3>Print surface preparation</h3>
<p>For printing, a special adhesive must be applied to the print bed (e.g., MAGIGOO HT) for the perfect first layer. We recommend using the adhesive in multiple layers.</p>

<h3>Menu update</h3>
<p>Connect the printer to the internet network. Then select <em>System -&gt; Check for updates</em>. Once the printer finds an update, it can be downloaded even during printing. The update will be installed after the print job is finished.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2024/08/296eae8fe7322053d1e51b0f155404cb.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="How to update firmware (HT90)" alt="" width="350" height="593" loading="lazy" /></p>
<h3>Offline update </h3>
<p>The HT90 can be used fully offline. This includes firmware updating. Download the firmware and add it to the root folder of a USB drive. Plug the USB drive with the FW to the LCD port and the printer will recognize it automatically.</p>
<h3>Browser update</h3>
<p>In this way, it is also possible to <strong>downgrade</strong> the firmware. Go to the printer to <em>More -&gt; Settings -&gt; Network</em>, and copy the IPv4 to your browser.</p>
<p>Go to the gears on the top right to open the settings on the web interface. On the new window, go to Versions, and select the Upload button.</p>

How to update firmware (HT90)

<p>The <strong>Prusa Pro HT90</strong> is engineered for maximum efficiency and reliability. However, it is still a mechanical device with components that require regular maintenance. Follow the guidelines below to keep your printer in perfect condition for as long as possible.</p>
<h3>Flexible steel sheets</h3>
<p>The Prusa Pro HT90 can use three types of print sheets, <strong>Textured</strong>,<strong> Satin</strong>,<strong> </strong>or<strong> PA nylon</strong>. </p>
<h4>Textured sheet</h4>
<p><strong>Never clean a textured sheet with acetone!</strong> This will create micro-cracks in the PEI layer which will cause significant surface deterioration over time.</p>
<p>The surface of this sheet is covered with a special polymer (Ultem) to ensure perfect adhesion. The powder-coated steel sheets are better for printing objects with materials such as PETG, CPE, or Flexfill (TPU) which tend to adhere too much to a smooth surface, but can be more easily removed from the textured one. <strong>For all details and considerations of the Textured sheet, please see <a href="http://help.prusa3d.com/ja/article/textured-steel-sheet_196534">Textured steel sheet</a>.</strong></p>
<h4>Satin sheet</h4>
<p><strong>Never clean a satin sheet with acetone!</strong> This will create micro-cracks in the PEI layer which will cause significant surface deterioration over time.</p>
<p>The Satin sheet further expands our line-up of print sheets. Its powder-coated surface with a lightly textured matte finish offers an optimal level of adhesion and is fully compatible with a wide range of common and less-common filaments. <strong>For all details and considerations of the Satin sheet, please see <a href="http://help.prusa3d.com/ja/article/satin-steel-sheet_196526">Satin steel sheet</a>.</strong></p>
<h4>PA nylon sheet</h4>
<p>Do <strong>not</strong> clean the <strong>PA nylon </strong>sheet with acetone, IPA (isopropyl alcohol), or other alcohol-based solvents (window cleaners, Windex, etc.), as this will damage the surface. Wash the special sheet before every print with clean water (use a wet cloth or sponge), then dry it. Greasy stains, such as fingerprints, can be cleaned with water with dishwashing soap. </p>
<p>The special PA nylon sheet is made for printing polyamides (Nylon) since their adhesion to standard PEI sheets is generally very poor. The sheet comes with a matt texture, similar to the satin steel sheet with a PEI surface. The sheet is compatible with most polyamides and PETG, other materials may have insufficient adhesion and should be printed on our standard PEI sheets. <strong>For all details and considerations of the PA nylon sheet, please see <a href="http://help.prusa3d.com/ja/article/special-pa-nylon-steel-sheet_341570">PA nylon sheet</a></strong>.</p>
<div class="warning-callout">Consumables such as printing plates are not covered by warranty. The warranty only covers consumables if they arrive already damaged or incorrectly manufactured. Print plates are consumables and the warranty only covers defects that become apparent immediately after unpacking.</div>
<h3>Keeping the printer clean</h3>
<p>After several hours of printing, various types of debris can start to accumulate in the printer chamber, such as filament pieces, dust, broken support remnants, etc.</p>
<p>Always ensure that all parts of the printer are clean. You can use a brush, a small broom, or a vacuum cleaner to remove the debris. </p>
<p>Do not clean the printer while it is printing. Clean the printer only after all parts have cooled down and the printer is turned off.</p>
<h3>Nozzle cleaning</h3>
<p>It is fundamental for the hotend and nozzle to be clean. Check the recommended methods and instructions for cleaning a nozzle used in a <a href="http://help.prusa3d.com/ja/article/high-flow-print-head-ht90_727185">high-flow print head</a>, and in a <a href="http://help.prusa3d.com/ja/article/high-temperature-print-head-ht90_726478">high-temp print head</a>. </p>
<h3>Filter replacement</h3>
<p>The top part of the printer's chamber contains a housing with a HEPA filter. This filter needs to be replaced or cleaned regularly. Follow the procedure in the <a href="http://help.prusa3d.com/ja/article/hepa-filter-replacement-ht90_726153">dedicated filter replacement article</a>. </p>
<p></p>


Regular printer maintenance (HT90)

<p>PPSU (polyphenylsulfone) is a technical thermoplastic material with excellent resistance to heat and chemicals and superior hydrolytic stability. The main characteristic of this material is the <strong>resistance to impact</strong>. It has a higher ductility and can withstand repeated sterilization cycles, making it more durable in applications involving mechanical stress.</p>
<p>It is ideal for applications requiring extreme stability and durability. Its properties include <strong>high mechanical strength, toughness, and wear resistance</strong>. With a temperature range from -100°C to over 200°C, PPSU is suitable for applications with extreme temperature resistance.</p>

HEPA filter replacement (HT90)

<p>You’ve probably guessed it already but the PEI 1010 isn’t exactly a “plug and print” material like our basic Prusaments (PLA, PETG…). Although we do our best to make our filaments as easy to print as possible, there are still certain physical limitations.</p>
<h3>Necessary hardware</h3>
<p>The melting point of this material is very high and so is the printing temperature, so <strong>you need an enclosed and actively heated 3D printer like the <a href="https://www.prusa3d.com/applications/prusa-pro-ht90_236004/">Prusa Pro HT90</a>.</strong></p>
<p>The moisture absorption is extremely fast and difficult to undo - <strong>you’ll need a <a href="https://www.prusa3d.com/product/memmert-uf30-filament-dryer/">professional dryer</a> (oven) and a <a href="https://www.prusa3d.com/product/prusa-pro-filament-drybox/">suitable dry box</a></strong>, or a dryer that can be connected directly to a printer. The spool placed outside without a dry box absorbs moisture in dozens of minutes. In a passive dry box (with silica gel only) the difference is noticeable after half a day or so and after several days the filament gets practically unprintable.</p>
<p>Finally, <strong>the print surface adhesion is also very high</strong> - here you’ll need a special separation layer like the <a href="https://www.prusa3d.com/product/magigoo-pro-ht-50ml/">MagiGoo HT</a>. To ensure good printability we designed and chose the following hardware that should work perfectly but you may use other equipment with similar properties too:</p>
<div class="tip-callout">
<ul>
<li><strong><a href="https://www.prusa3d.com/applications/prusa-pro-ht90_236004/">Prusa Pro HT90</a> with HT hot end</strong> - Printer capable of working at 410 °C for the nozzle, 150 °C for the heatbed, and at least 90 °C for the enclosure</li>
<li><strong><a href="https://www.prusa3d.com/product/memmert-uf30-filament-dryer/">Memmert UF30 Filament Dryer</a></strong> capable of holding stable temperature 150 °C for 6-8 hours</li>
<li><strong><a href="https://www.prusa3d.com/product/prusa-pro-filament-drybox/">Prusa Pro Filament Drybox</a></strong> capable of being connected to the 3D printer while printing</li>
<li><strong><a href="https://www.prusa3d.com/product/ht90-textured-powder-coated-steel-sheet/">HT90 Textured Powder-coated Steel Sheet</a> or <a href="https://www.prusa3d.com/product/ht90-pa-nylon-powder-coated-steel-sheet/">HT90 PA Nylon Powder-coated Steel Sheet</a></strong></li>
<li><strong><a href="https://www.prusa3d.com/product/magigoo-pro-ht-50ml/">MagiGoo HT</a></strong> - specialized high-temperature resistant separation layer applied on the print surface before printing (necessary for textured sheet only)</li>
</ul>
</div>
<h3>Step-by-step successful printing process</h3>
<p>Now, here’s a process you should do to print with Prusament PEI 1010 successfully:</p>
<ol>
<li><strong>Preheat the dryer</strong> (oven) to 150 °C and insert PEI 1010 spool. Dry the filament at 150 °C for 6-8 hours.</li>
<li><strong>Prepare the dry box:</strong> the desiccant inside should not be depleted (see the desiccant color). If it’s depleted, either dry it in the oven properly or replace it with fresh desiccant.</li>
<li><strong>After drying the filament, move it immediately to the dry box.</strong> This is crucial, as the PEI may absorb moisture after dozens of minutes!</li>
<li><strong>Prepare the HT90 printer.</strong> The printer should have an HT print head mounted - replace the printhead if the high-flow is mounted. Check the print sheet - PEI 1010 should be printed on the Textured powder-coated print sheet and PA Nylon print sheet only.</li>
<li>If you print in the Textured powder-coated print sheet, <strong>spread a thin even layer of the MagiGoo HT</strong> on the print surface. It is not necessary to apply the MagiGoo on the PA Nylon print sheet.</li>
<li><strong>Preheat the HT90</strong> (Nozzle: 410 °C, Heatbed: 150 °C, Chamber: 90 °C) and load the filament. Note that the filament should remain closed in the dry box. It should only be connected to the printer through the PTFE tube.</li>
<li><strong>Slice the model with the original PrusaSlicer profile.</strong> Other profiles may not work properly.</li>
<li><strong>Print it!</strong></li>
</ol>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2024/09/b582528dae278a2e7f943269983ee96a.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="How to print with PEI 1010" alt="" /></p>
<p><em>Only a thin layer of MagiGoo HT is necessary</em></p>
<p>If everything is done correctly, the print should have a nice glossy transparent amber look with no stringing and oozing.</p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2024/09/b0f230f2a715d04c7bc0c312e9925a6b.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="How to print with PEI 1010" alt="" /></p>
<p><em>Example of a nice PEI 3D-printed part with no obvious errors.</em></p>
<h3>Choosing the right model</h3>
<p>Finally, you should know that the <strong>Prusament PEI 1010 tends to warp a lot during printing</strong>. This does not mean that you should print only the tiniest parts possible but it’s something you might want to consider when designing and slicing the models. We did our best to make the filament as easy to print as possible but still, working with such filaments requires some experience and knowledge. As for the latter, here are a few tips to make the best of it:</p>
<ul>
<li><strong>Consider the printed object size.</strong> The warping is most significant in the largest prints. This means that printing an object that has full-bed dimensions may not be the best choice. We recommend printing small to medium-sized parts for the best results.</li>
<li>Print bases with narrow angles, such as square shapes (or narrower ones) tend to warp much more than round ones. <strong>The best model is the one that has a flat circular base</strong> placed on the print surface. Don’t forget to consider it when designing and slicing a model.</li>
<li>No matter the size, <strong>we always recommend printing the PEI 1010 with a brim.</strong> This significantly reduces the warping issue.</li>
</ul>
<h3>Most common errors</h3>
<p>Finally, let's show some of the most common errors visible on the following 3D printed part:</p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2024/09/49cecbaa6032be18236907097bc2b9f2.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="How to print with PEI 1010" alt="" width="2506" height="1880" loading="lazy" /></p>
<ol>
<li><strong>The filament is not dry</strong> - this is mostly noticeable at the bottom part, where the extruded material has a "foamy" structure, the model loses its desired dimensional properties and mechanical resistance too.</li>
<li><strong>This model was printed with other than the recommended PrusaSlicer profile.</strong> This is why the model is full of cavities (bubbles) noticeable in every layer, which significantly affect the model's mechanical properties.</li>
<li><strong>This model was also full of strings</strong> (not visible in the photo above) due to the errors mentioned above.</li>
<li><strong>Notice the warping:</strong> the model peeled off the print sheet even with the brim. This was caused by three reasons. First, the model is not exactly round and compact. The shape is not ideal but a larger brim might help. Second, the wet filament tends to warp more and stick less to the print surface than the dry one. Finally, we applied too much MagiGoo HT on the surface.</li>
</ol>

How to print with PEI 1010

<p>PPS or Polyphenylene sulfide is a semi-crystalline technical thermoplastic material suitable for 3D printing characterized by high resistance to heat and chemicals. The main characteristic of this material is the <strong>chemical resistance</strong>, particularly to acids, alkalis, and solvents. It is highly resistant to organic solvents and does not dissolve in any known solvent below 200°C.</p>
<p>With thermal stability from -100°C to over 200°C, PPS is an ideal choice for <strong>applications requiring resistance in extreme temperatures.</strong> This material has excellent mechanical properties, including high toughness, strength, and wear resistance, however, it can be more brittle than materials like <strong>PSU</strong> and <strong>PPSU</strong>. Its outstanding electrical characteristics, such as high dielectric strength and low dissipation factor, further increase its attractiveness for electrical and electronic applications.</p>

PPS (Polyphenylene sulfide)

<p>PSU, or Polysulfone, is a technical thermoplastic material with an excellent combination of properties that make it suitable for various applications including 3D printing. Its high resistance to temperature, chemicals, and mechanical stresses ensures reliability and performance in demanding conditions.</p>
<p>This material has excellent mechanical properties such as high strength, toughness, and wear resistance, making it an ideal choice for applications requiring high creep resistance and suitability for high continuous service temperatures alongside the usual requirements of high mechanical stability and stiffness.</p>
<p>PSU is an excellent alternative to ULTEM 9085. While having a lower cost per kilogram and lower density (giving you more filament per kilogram), it maintains superior thermal properties. Its higher glass transition temperatures and heat deflection temperature give it higher strength and stiffness at elevated temperatures.</p>

<p>An actively heated chamber is necessary to print this material with a temperature of 65°C or higher. A heated chamber is essential for printing high-temperature materials in FFF, due to several reasons:</p>
<ul>
<li><strong>Prevents deformation: </strong>Maintains stable temperatures to reduce deformation and cracking.</li>
<li><strong>Improves layer adhesion:</strong> Supports stronger connections between layers.</li>
<li><strong>Preserves the properties of the material: </strong>Ensures proper crystallization and strength of the material.</li>
<li><strong>Prevents clogging:</strong> Prevents premature cooling of fibers and prevents problems with extrusion.</li>
<li><strong>Improves accuracy:</strong> Reduces thermal expansion and improves dimensional accuracy.</li>
</ul>
<h3>Print surface preparation</h3>
<p>For printing, a special adhesive must be applied to the print bed (e.g., MAGIGOO HT) for the perfect first layer. We recommend using the adhesive in multiple layers.</p>
