<h3><strong>Original Prusa MK4</strong></h3>
<p>Assembled printers and printer kits are <strong>IN STOCK!</strong> </p>
<h3><strong>Original Prusa XL</strong></h3>
<p>Lead time for all printer variants is now 6 weeks.</p>
<p>The XL was switched from a preorder product to a regular product on March 1st, 2024. We no longer add pre-order gifts to orders placed after this date.</p>
<p>All preorders created before March 1st, 2024, are ready to be completed. Just sign in to your account, select the shipping method, and complete the payment. You can also change the variant of XL and/or add more products to the order. Your printer will be placed in the shipping queue based on the payment date. However, you will still get the two extra pre-order gifts as compensation for the delay: an extra print sheet and the Nextruder adapter for third-party nozzles. </p>

<h3>Basic info</h3>
<div><strong>PETG</strong> is one of the most easily printable materials, it is <strong>inexpensive and suitable for beginners</strong>. Relatively high tenacity and temperature resistance make it <strong>suitable for printing technical parts</strong> (for example parts of our printers).</div>
<div>&nbsp;</div>
<div><strong>Recommended nozzle temperature:</strong> 230 °C for the first layer, 240 °C for the other layers</div>
<div>&nbsp;</div>
<div><strong>Recommended bed temperature:</strong> 85 °C for the first layer, 90 °C for the other layers</div>
<div>&nbsp;</div>
<div><strong>Heatbed:</strong> Using powder-coated TXT or satin sheet is highly recommended. Printing on smooth PEI surface might damage the sheet.</div>
<h3>Description</h3>
<div>
<p><a href="https://www.prusa3d.com/category/prusament-petg/"><strong data-stringify-type="bold">PETG</strong></a> (Polyethylene Terephthalate modified with Glycol) is a commonly used technical material, popular among 3D printer users for its <strong>low price and good printability</strong>. It’s tenacious, with good temperature resistance; PETG is most commonly used for printing various mechanical parts, holders, clamps, and waterproof parts (thanks to great layer adhesion).</p>
<p>PETG has a glossy surface, adheres greatly to a print sheet, and <strong>does not shrink or warp</strong> (it has very little thermal expansion), therefore it’s suitable for printing large models. Plus, its high tenacity and flexibility often <strong>prevent it from breaking.</strong> Due to good temperature resistance, PETG parts are suitable both for interior and most exterior use (with temperatures below 80 °C). <strong>Parts of our printers are made of PETG!</strong></p>
<p>The letter G in PETG means that it’s modified with glycol during the manufacturing process. Glycol makes PET less brittle, easier to print, and more transparent for translucent prints. Of course, you can print also with PET filaments without glycol. However, printing with only PET is challenging and does not offer any advantage whatsoever.</p>
<div class="warning-callout">Even though PETG in itself may be considered <a href="http://help.prusa3d.com/article/food-safe-fdm-printing_112313">food-safe</a>, it consists of layers, as every 3D print, in which bacteria can grow over time. You can prevent this by applying a <strong>food-safe(epoxy) coating.</strong> Also, a stainless-steel nozzle should be used for if food is the intended application.</div>
<p>Although <strong>PETG</strong> is frequently used in <strong>food industry</strong> and is considered <strong>food-safe</strong>, we do not recommend it (or any other filament) for printing dishes or other stuff that comes into direct contact with food. The main reason is tiny print layer surface grooves that can support numerous bacterial colonies. But if you still want 3D printed dishes, we suggest <strong>applying a special layer</strong> that seals the surface (food-safe coating) and printing with a clean steel nozzle.</p>
<p>Some of the manufacturers <strong>enrich PETG with various additives</strong> and sell these materials under different names. For example, Spoolworks EDGE by E3D is modified PET/Copolyester Blend with additives. The goal is to acquire better visual qualities, surface and layer adhesion, etc.</p>

<h3>Best use</h3>
<p>PETG is used universally but is especially suitable for mechanical parts for both indoor and outdoor use. We use PETG to print parts for our printers! Plastic bottles are also made from this kind of material.</p>
<h3>Tips for successful printing</h3>
<p><strong>Temperature settings and cooling</strong></p>
<p>Unlike PLA, <strong>PETG requires a heated bed (85 °C).</strong> Its bridging- and overhang-behavior is usually worse, plus it is prone to stringing. Stringing can be moderated with higher retractions and lower nozzle temperature, but we suggest <strong>using the PrusaSlicer profiles that should work fine.</strong> It’s important to <strong>cool the PETG print</strong> - this helps to keep the model detailed and prevents stringing and oozing. But if you want the model to be as tough as possible, try to turn off the print fan. Higher filament temperature improves merging between layers which leads to better mechanical resistance. Otherwise, we recommend printing the first few layers with the print fan off to prevent deformation, then with the fan running at half its power.</p>
<div class="warning-callout"><strong>Do not print on the smooth PEI sheet</strong> as the adhesion may be too strong!</div>
<p><strong>Print surface preparation</strong></p>
<p>Make sure the print surface is clean, as described in <a href="http://help.prusa3d.com/article/first-layer-issues_1804">our dedicated article</a>. It is advisable to use one of the <strong>powder-coated print sheets. Do not print on the smooth PEI sheet</strong> as the adhesion may be too strong! If you decide to use the smooth PEI sheet anyway, apply a glue stick on it before printing.</p>
<p><strong>Adding more perimeters for more solid parts</strong></p>
<p>If you want to print truly solid parts, <strong>try to increase the number of perimeters</strong> instead of adding more infill.</p>
<h3>Postprocessing</h3>
<p>PETG can be easily sanded both dry and wet.</p>
<p><strong>Dissolving PETG</strong></p>
<p><strong>Dissolving and smoothing PETG</strong> is possible only in a laboratory by skilled lab workers using <strong>dangerous chemicals</strong> (Dichloromethane).</p>

Different nozzle types

<p>Prusa Connect and PrusaLink are two remote printing solutions developed in-house by Prusa. Its origin is in the management system used in our <a href="https://blog.prusaprinters.org/guinness-world-records-1096-original-prusa-3d-printers-running-at-the-same-time_30677/">record-sized print farm located in Prague HQ.</a></p>
<ul>
<ul>
<li><strong>Prusa Connect</strong> is a cloud service for remote printing available from anywhere.</li>
<li><strong>PrusaLink</strong>* is the client-side running locally on your printer, accessible from local network</li>
</ul>
</ul>
<p><em>*formerly known as Prusa Connect Local</em></p>
<p> </p>
<h2>What is Prusa Connect?</h2>
<p>Prusa Connect (<a href="http://connect.prusa3d.com">connect.prusa3d.com</a>) allows you to control your individual printers or even manage a print farm from anywhere in the world.</p>
<p style="text-align: center;"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/08/9f18d1552ef82ea7ef4960a43a86a17b.png" sizes="(min-width: 1024px) 820px, 100vw" srcset="Prusa Connect and PrusaLink explained" alt="" width="900" height="607" loading="lazy" /></p>
<p style="text-align: center;"><em>Example of Prusa Connect interface (cloud service)</em></p>
<p> </p>
<p>It is available for free to the owners of selected Original Prusa printers (see the list below). You get a free 1 GB of cloud storage for your G-codes and telemetric data. The full list of features and pricing for end customers or businesses will be announced later on.</p>
<p>Furthermore, Prusa Connect is able to monitor the use of each printer individually, providing valuable statistics of your production environment. </p>
<p> </p>
<h2>What is PrusaLink?</h2>
<p>Much like <a href="http://help.prusa3d.com/article/about-octoprint_1790">Octoprint</a>, this remote printer-management system runs locally on your Original Prusa printer.</p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/01/12af6bd49830e088.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="PrusaLink and Prusa Connect explained" alt="" width="1451" height="800" loading="lazy" /></p>
<p style="text-align: center;"><em>Example of PrusaLink interface (local network)</em></p>
<p> </p>
<p>Its main goal is to provide communication between your printer and the Prusa Connect cloud. The secondary function is to provide a web interface, which can be used on your local (home) network only. Simply paste the printer's IP address into your web browser to access it. Using PrusaLink alone you can monitor your printer, upload G-codes, start or cancel a print. </p>
<p> </p>
<h2>How to install and configure PrusaLink and Prusa Connect?</h2>
<p>To use the Prusa Connect, you have to first set up the PrusaLink on your printer. The guides below will take you to step by step through the entire process.</p>

<h3>Next-gen Original Prusa printers</h3>
<p>Such as the<strong> MK4, MK3.9, MK3.5, XL, MINI/+, SL1/SL1S </strong> as well as the other upcoming models have the PrusaLink built-in. You can connect the printer either using Wi-Fi or a wired LAN (Ethernet) network. Note that on MINI/+, you have to first <a href="http://help.prusa3d.com/guide/installing-wi-fi-and-prusalink-mini-_316781">install the Wi-Fi module</a> to use the wireless functionality.</p>

</ul>
<p> </p>
<h3>Original Prusa i3 MK3/S/+ or MK2.5/S</h3>
<p>In this case, the PrusaLink name also refers to the required hardware solution of a Raspberry Pi (RPi). These printers don't have enough performance, therefore additional hardware is required. PrusaLink is a replacement for the discontinued <a href="http://help.prusa3d.com/article/prusaprint-rpi-zero-and-octoprint_2180">PrusaPrint solution</a> (Octoprint and the RPi Zero W).</p>
<h4>Which Raspberry Pi should I get for my i3 (MK3/S/+ or MK2.5/S)?</h4>
<p>For your MK3/S/+, you need to get a Raspberry Pi (RPi) to make the PrusaLink and Prusa Connect work. The supported RPi boards are listed below and if you are about to purchase a new one, it is highly recommended to seek the latest generation, as the older ones might be slower.</p>
<p>On MK3/S/+, you can attach the RPi Zero <a href="http://help.prusa3d.com/guide/prusalink-and-prusa-connect-setup-mk3-s-_221744">directly onto the printer’s mainboard</a> or use the <a href="http://help.prusa3d.com/guide/prusalink-prusa-connect-with-rpi-3-4-usb-mk2-5-s-mk3-s-_469341">USB connection</a>.<br />On MK2.5/S, you have to use the <a href="http://help.prusa3d.com/guide/prusalink-prusa-connect-with-rpi-3-4-usb-mk2-5-s-mk3-s-_469341">USB connection</a> to the RPi. Then, the PrusaLink and PrusaConnect setup is fairly similar to the MK3/S/+.</p>
<p>Since the RPi doesn't have internal storage, you need to get a MicroSD card. Recommended SD card: Micro SD, SDHC standard, Class 10, 8GB or more. Preferably, choose a name-brand card known to work with RPi. Do backups regularly as even a name-brand card doesn’t guarantee you won’t lose your data. </p>

<div class="warning-callout"><strong>What not to do while RPi Zero W/2 is connected and the printer is powered up:<br /></strong><br />- Don't move any of the printer's axes by hand! Use the Move Axis menu only.<br />- Don't connect or disconnect the RPi.<br />- Don't insert or remove the microSD card inside the RPi.<br />- Don't touch the RPi board.<br />- For connecting or powering the RPi, don't use any other methods than the ones endorsed by Prusa.<br />- Only follow the guidance from the official documentation issued by Prusa Research.<br />- Prusa Research is not responsible for any damage done by or caused to third-party hardware.</div>

How to update firmware (MK4/XL)

<p>On the Original Prusa XL, adjusting the belt to the optimal tension is crucial to achieving good quality on the prints. A loose belt can cause <a href="http://help.prusa3d.com/article/layer-shifting_2020">Layer shifting</a>, <a href="http://help.prusa3d.com/article/ghosting_1801">Ghosting</a>, or other print abnormalities, like getting an irregular shape instead of a perfect circle. An over-tightened belt can cause an irregular movement in the X and Y axes.</p>
<p>The Original Prusa XL geometry is <strong>CoreXY</strong>: it has two belts for the X-axis. </p>
<h3>Belt tuner</h3>
<p>We have our own <a href="https://belt.connect.prusa3d.com/">belt tuner</a>. The application determines the belt tension by measuring the frequency of the vibration generated by strumming it. Follow the instructions in the video below to adjust the belt. </p>
<div class="note-callout">Once you tighten the belt on both sides, ensure that the two sides are perfectly aligned. If needed, follow the steps in the <a href="http://help.prusa3d.com/article/adjusting-belt-tension-xl_401793#Alignment">alignment</a> paragraph to fully align the two sides.</div>
<p style="text-align: center;"><iframe src="https://www.youtube.com/embed/lqC6rVrFLuY" width="560" height="314" allowfullscreen="allowfullscreen" loading="lazy"></iframe></p>
<h3>Homing tower</h3>
<p>We prepared a specific <a href="https://www.printables.com/model/542670-homing-tower" target="_blank" rel="noopener">homing tower</a>, to visualize possible issues with the belt tension and have the possibility to correct them on the spot. </p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/08/03ee25ae808b03bc2a92e9ba69b4d1d9_painted.jpeg" sizes="(min-width: 1024px) 820px, 100vw" srcset="Adjusting belt tension - REVIEW (XL) [No belt tensioner, add GCode homing tower]" alt="" width="500" height="373" loading="lazy" /></p>
<p>In case the <span style="color: #e03e2d;"><strong>belt is loose</strong></span>, the tower will have an inconsistent finish, with scattered material on the walls instead of a smooth finish. Without interrupting the print, tighten the screws on both Y-axis rails by half turn. </p>
<p>If the print finish does not fully improve, repeat the procedure once again, until the homing tower has a <strong><span style="color: #3598db;">smooth, consistent finish</span></strong>. </p>
<p>An over-tightened belt can result in <span style="color: #b96ad9;"><strong>layer shifting</strong></span>.</p>
<p>Once the tower has a smooth finish, loosen the same screws very slightly, and observe if this further improves the tower. Repeat the procedure until the tower has an ideal finish. </p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/03/XL_belt02.jpg" alt="" width="500" height="375" loading="lazy" /></p>
<p> </p>
<h3>Alignment</h3>
<p>It is crucial to have perfect alignment between the right and left sides.</p>
<div class="tip-callout">Tightening the right Y-axis rail reduces the space between the CoreXY Front Left and the X-axis on the right side but creates space on the left side, and vice versa. </div>
<p>Move the X-axis all the way to the front of the printer, and move the X-carriage with the extruder all the way to the left.</p>
<p>Test the alignment by <strong><span style="color: #ba372a;">squeezing</span></strong> the CoreXY Front Left and the X-axis on either side: there should be no <span style="color: #3598db;"><strong>play between the parts</strong></span>. If there is play, tighten the <span style="color: #b96ad9;"><strong>tensioning screw</strong></span> on the same side slightly, move the X-axis assembly back and all the way to the front, and test the alignment again on both sides. </p>
<p>The right side image shows the mechanism behind the <span style="color: #b96ad9;"><strong>tensioning screw</strong></span>. Tightening the screw pulls the <span style="color: #e67e23;"><strong>tensioner</strong></span> towards the front, resulting in a more tensioned belt on that side. </p>

</table>
<p>Repeat the same procedure until both sides are perfectly aligned and without any play. Once at this stage, check the belt tension once again using the belt tuner app. Both belts need to be at the same tension, and at the same time, the X-axis has to be aligned. </p>
<p>In case there is a difference on the test, slightly tighten the screw on the side:</p>
<ul>
<li>tighten the right side to tension the upper belt as seen from the front.</li>
<li>tighten the left side to tension the lower belt as seen from the front. </li>
</ul>


Adjusting belt tension (XL)

<p>It is recommended to regularly take some time to maintain your Original Prusa XL. This should be done even if the printer is working perfectly. <strong>The inspection and maintenance of its various components should be done every ~200-300 hours of print time</strong>.</p>
<h3>Useful tools</h3>
<p>Besides the usual tools, such as Allen keys, needle-nose pliers, and IPA (IsoPropyl Alcohol) + paper towels, you might need:</p>
<ul>
<li><strong>Compressed air</strong>: also known as canned air. Be sure to not hold it upside down while spraying - otherwise, you could damage any electronic components while trying to clean them.</li>
<li><strong>Brush</strong>: a small brass brush is a useful tool for cleaning the heaterblock. If you don't have a brass brush any brush with hard bristles will do the job. </li>
<li><strong>Prusa Lubricant</strong>: a tube of Prusa Lubricant is included with the Original Prusa XL. It is used in the Z-axis leadscrew paragraph. </li>
</ul>
<div class="warning-callout"><strong>DO NOT use Prusa Lubricant on the linear rails! </strong></div>
<h3>Axes check</h3>
<p>Ensure that there is no debris or dust on the <strong>linear rails</strong>. If there is, clean them using a clean paper tissue or a clean cloth <strong>with NO de-greaser</strong> and <strong>with no chemicals</strong>, as these might damage the rubber in the carriage. The factory lubrication for linear rails is effective for at least 2 years. </p>
<h3>Z-axis leadscrew</h3>
<p>After ~500 hours of print time, lubricate the Z-axis leadscrews.</p>
<ol>
<li> Go into the printer menu to <em>Control -&gt; Autohome</em>.</li>
<li> Lubricate the Leadscrew.</li>
<li> Go into the printer menu to <em>Control -&gt; Move axis -&gt; Move Z</em>, and move the axis all the way down.</li>
<li> Again go into the printer menu to Control -&gt; Autohome.</li>
</ol>
<p>After that, your lead screws will be lubricated.</p>
<h3>Belt</h3>
<p>Attach the belt tensioner on the top belt on the X-axis. The belt tensioner has a pointer, check if it is in the optimal range. The ideal position of the pointer is in the center area, closer to the max mark.</p>
<p>You can also use the <a href="https://belt.connect.prusa3d.com/">Prusa Belt tuner app</a>.</p>
<h3>Side filament sensor</h3>
<p>The side filament sensor on the printer may accumulate leftover filament over time. To prevent false readings, follow the guide <a href="http://help.prusa3d.com/guide/how-to-clean-the-side-filament-sensor-xl_547477">How to clean the side filament sensor (XL)</a>.</p>
<h3>Flexible steel sheet</h3>
<p>All flexible steel sheets should be cleaned regularly to ensure adhesion, but the exact methods and washing solutions can differ depending on your type of sheet.</p>
<p>You can find more information on how to take care of your flexible steel sheet <a href="http://help.prusa3d.com/article/flexible-steel-sheets-guidepost_2195">in this article</a>.</p>
<div class="warning-callout">Acetone should be used sparingly for cleaning, and only be used on the Smooth steel sheet! <strong>Never use acetone on the Textured or Satin steel sheet </strong>as the surface will be permanently damaged.</div>
<h3>Fans</h3>
<p>The Original Prusa XL is equipped with a hotend fan, and with a print fan. The printer can detect if any of its fans stop spinning. However, that does not mean you should not check them during maintenance. Dust or plastic build-up can decrease their efficiency or even damage them.</p>
<p>Both fans should be checked and cleaned after a few hundred hours of printing. With the fan <strong>not </strong>moving, dust can be removed with compressed air in a spray can, small plastic threads can be removed with tweezers.</p>
<div class="note-callout">Do not blow compressed air on a running fan: the fan can get damaged this way. </div>
<h3>Nextruder</h3>
<div class="warning-callout">When accessing the extruder parts, do not open the gearbox: this action can cause issues on the extrusion, and will <strong>void the printer warranty</strong>. </div>
<p>The primary gear and the bearings attached to the Idler Shaft in the extruder do not need any lubricant. Over time, a deposit of filament debris can form in the grooves of the primary gear, which then causes insufficient filament extrusion. Access the extruder by lifting the Idler Nut, and then moving the Idle Shaft. You can blow away the dirt with compressed air, or use a brass brush or an ordinary toothpick. Use the access hole on the front of the extruder/tool head.</p>

<h3>Heaterblock</h3>
<div class="warning-callout"><strong>CAUTION</strong>: Heated parts can cause severe burns!</div>
<p>If the heaterblock is covered with plastic, it can affect its thermal properties. To clean it, heat the nozzle for 3 to 5 minutes at 250 °C, and <strong>turn the printer off</strong>. Immediately after that use a small brass brush to clear away any old plastic stuck on the nozzle and heaterblock. Be extra careful around the fragile wires that join the heaterblock.</p>
<p>You can also use the <a href="https://www.prusa3d.com/product/prusa-nextruder-silicone-sock-set/">Nextruder Silicone sock</a> to protect your heater block.</p>
<h3>Electronics</h3>
<p>Every ~600-800 printing hours access the electronic boards for a visual check.</p>
<div class="warning-callout">Before touching the electrical connections, please make sure that the printer is <strong>fully cooled down</strong>, <strong>switched off</strong>, and <strong>unplugged from the main power source for at least 10 minutes</strong>.</div>
<ul>
<li>Check if there are any pinched or worn cables on the printer.</li>
<li>Access the electronic boards and blow compressed air in between the cables to get rid of dust. </li>
<li>Check the connection of all of the wires on the electronic boards. </li>
</ul>
<h3>Firmware and software</h3>
<p>You should always be using the latest <a href="http://help.prusa3d.com/article/how-to-update-firmware-mk4-xl_453086">stable firmware</a> version that we have published for your specific printer model. You can check the firmware version you have, by navigating to <em>LCD menu - Info - Version info</em>. </p>
<p>We also recommend using the latest version of our <a href="http://help.prusa3d.com/article/install-prusaslicer_1903">PrusaSlicer</a>, as it enables you to <strong>enjoy all the features</strong> of your printer. It even saves information about the printer model, nozzle diameter, and firmware version directly into the g-code file so that the printer can warn you if anything is out of date or incompatible.</p>
<h3>Tool-changer/toolhead cleaning</h3>
<p>This can be made along with the rest of the maintenance, or it can also be done if you notice that your prints have banding or ringing issues. The metal connection of the ToolHead and the ToolChanger needs to be lubricated to work smoothly. For that, use the guide <a href="http://help.prusa3d.com/guide/how-to-lubricate-the-coupler-pins-on-original-prusa-xl-multi-tool_636777">How to lubricate the coupler pins on Original Prusa XL (Multi-Tool)</a>.</p>
<p> </p>


Regular printer maintenance (XL)

<p style="text-align: left;">The Original Prusa XL can print true multi-material prints without the need for any purge or wipe tower.</p>
<p style="text-align: left;">The purge tower is turned <strong>ON</strong> by default (when you are mixing materials or colors) because it's the best way to cover a wide range of materials and to ensure maximum reliability when using our default profiles.</p>
<p>However, under certain circmunstances, you can turn it off and still get perfect prints. The main factor is the filament quality and especially <strong>how dry the material</strong> <strong>is</strong>. The moisture in the filament is the main cause for the filament leaking out of the pre-heated nozzle during travel moves and when the tool is parked. It also greatly affects stringing.</p>
<p>If you want to try printing without the purge tower, make sure your filament is dry and check on the print regularly.</p>
<p>You can learn about how to properly dry filament in <a href="http://help.prusa3d.com/article/drying-filament_332086">our guide</a>.</p>
