Como limpar a placa de construção de uma impressora 3D baseada em resina?

Resin based 3d printing will be messy compared to the wire based 3d printers. Try to keep your work place clean everytime & Ensuring a clean and efficient resin-based 3D printing process is paramount for optimal results. Always prioritize safety by wearing gloves and goggles when handling resins. Follow OEM guidelines meticulously: pour excess resin back into the container, clean the build plate with the recommended IPA concentration, and inspect thoroughly. Handling the VAT requires careful cleaning, inversion, and drying for a minimum of 2 hours. Post-processing, including support removal and fine emery work, contributes to impeccable print quality. Let's embrace these best practices for a seamless resin printing experience.

The most important tooling, that I feel is required while dealing with resin printing, is the scraper blade. Make sure it is nice and sharp, so that it can easily separate the part from the build plate, but also not very sharp otherwise it may scratch the plate or the part. Also, its thickness is very important. If the blade is very thin, it will wobble and might even buckle. Do check the handle quality as well. It should not detach with time. The blade should also be kept safely, inside an appropriate covering, ensuring the safety of the tool, as well as the workspace and personal. The other important tool to look at is the chemicals (IPA). Do check the quality (expiry) and the quantity to be dispensed.

One important note is how you dispose of the dirty paper (lint free) towels after wiping down the plate. Resin is very toxic and should be utilised properly if not cured by you. One way to go is to expose the towels to sunlight or your curing station before throwing them into a trash bag. If you do not cure, make sure you dispose of them at your local chemical utilisation station. This also saves you from the mess liquid resin can generate as it will drop out of the trash bag.

Pour nettoyer après une impression 3D avec de la résine, préparez votre espace de travail et rassemblez les outils nécessaires : Outils : Utilisez une spatule en plastique pour enlever la résine durcie, des gants pour protéger vos mains, de l'alcool isopropylique (IPA) pour dissoudre la résine, un vaporisateur pour appliquer l'IPA, des essuie-tout ou chiffons non pelucheux pour nettoyer, et un sac poubelle pour les déchets. Espace de travail : Assurez-vous que l'espace est bien ventilé et assez grand pour un nettoyage aisé, avec toutes les surfaces protégées contre les éclaboussures. Sécurité : Portez des gants et, si nécessaire, des lunettes de protection et un masque pour éviter l'exposition aux vapeurs de résine et de solvant.

In addition to what others have said, ensure work is done within a well-ventilated area with no desiccant or odour-absorbing materials such as silica gel, carpet or foam. These materials can trap the VOC's emitted by the printer and slowly release them over time.

Optional wird die Buildplate mit in die Prozess-Waschanlage gelegt und wie vorher die gedruckten Bauteile mit gereinigt. Danach kann diese dann einmal mit trockenen Tüchern abgewischt werden. Und schon ist die Buildplate sauber.

Make 100% sure you are WEARING GLOVES and SAFETY GLASSES every time you handle uncured resin. Safety first! No excuses!!!!!!

Please check to be sure you wear all the correct PPE, such as eye protection and an appropriate respirator. It might seem like overkill, but over time chronic exposure to these resins can cause additional harm. PM me if you have further safety questions.

I would make sure that if you are using any scraper that it is plastic. Put the extra resin back into the bottle it came from to save what you can and not to dispose of incorrectly. Check with your local ordinates for how to properly dispose of additional resin (eg. not down a sink).

The build plate is best kept at a high temperature when cleaning to ensure the resin deposits don’t solidify on the build plate. Afterwards, a flat scraper can be used to clean off the resin deposits. It’s important to maintain a flat surface before a printing process begins, because starting a new print with deposits on the surface, will reduce the quality of the new print.

Acetone is highly effective for cleaning certain types of resin (although it may not be suitable for all resin types, check your supplier guidelines). Apply acetone with a lint-free cloth or a dedicated applicator. Do not use abrasive materials that could scratch the build plate. Gently wipe the build plate surface to remove resin residue. This has worked wonders in some of our setups, much better than IPA.

Utilisation de l'air comprimé pour le nettoyage : Après avoir retiré les gros morceaux de résine, vous pouvez utiliser de l'air comprimé pour éliminer les petits résidus et la poussière de la plaque de construction. Tenez la bombe d'air comprimé à une distance sécuritaire et pulvérisez l'air sur toute la surface de la plaque, en insistant sur les coins et les recoins. L'air comprimé est efficace pour déloger les particules fines qui peuvent être difficiles à atteindre avec un chiffon. Après cette étape, vous pouvez procéder au nettoyage final avec un solvant comme mentionné précédemment. Assurez-vous de réaliser cette opération dans un espace bien ventilé, car l'utilisation d'air comprimé peut disperser des particules fines dans l'air.

You use IPA solution or any other available solvent in your industry to clean the build plate and make it dry and finally wipe with tissue paper or clean clothes.

In my opinion, spraying and wiping the build plate with a solvent, such as isopropyl alcohol, is a recommended method for cleaning a resin-based 3D printer's build plate. This helps remove resin residues, ensuring optimal printing conditions.

In the context of RepRap 3D printing with filament-based printers, the steps mentioned, particularly the use of solvents like IPA, are not typically applicable. RepRap printers using Fused Filament Fabrication (FFF) technology commonly employ materials like PLA, ABS, or PETG, which do not require post-processing with solvents as is the case with resin-based printing.

J'ajoute à ces éléments qu'un plateau sans "défauts" peut engendrer des problèmes d'adhérences. Par expérience, nous avons tenté de rattraper l'état d'un plateau ayant de grandes rayures. Nous avons poli la surface et les erreurs d'impression étaient nombreuses. Pour corriger cela, l'utilisation d'un abrasif pour créer quelques rayures légères a été une bonne solution. C'est pourquoi nous trouvons aujourd'hui des plateaux avec des reliefs pour augmenter l'adhérence. Bien évidemment, cela dépend de votre machine et des résines utilisées.

Augmentation de la rugosité de surface : Le ponçage crée une surface légèrement rugueuse, ce qui permet à la première couche de résine de mieux adhérer à la plaque. Cela est particulièrement utile pour les impressions avec des détails fins ou des surfaces larges et plates. Nettoyage après ponçage : Après le ponçage, il est essentiel de nettoyer soigneusement la plaque pour enlever la poussière de ponçage. Vous pouvez utiliser de l'alcool isopropylique et un chiffon non pelucheux pour ce faire. Précautions : Il est important de ne pas trop poncer, car cela pourrait endommager la plaque ou modifier sa planéité. Le ponçage est une mesure temporaire et ne devrait pas être fait trop fréquemment.

Thorough drying prevents any residue or moisture from interfering with future prints. Inspect the plate under good lighting to ensure it's entirely clean. Even tiny bits of resin left behind can affect print quality.

Il est essentiel de sécher complètement la plaque de construction et de l'inspecter minutieusement. Je tiens à souligner l'importance de cette inspection régulière pour détecter tout dommage susceptible d'affecter les impressions. L'idée de poncer ou de polir la plaque pour en restaurer la surface est excellente. Cependant, il est important de le faire avec précision pour ne pas altérer la planéité de la plaque. En cas de dommages importants, le remplacement de la plaque est effectivement la meilleure solution.

Avant de reprendre l'impression, il est recommandé de faire un test d'adhérence sur la plaque de construction. Vous pouvez imprimer un petit objet ou une couche de test pour vérifier si la résine adhère correctement à la plaque. Cela vous permettra de détecter d'éventuels problèmes d'adhérence avant de lancer des impressions plus longues ou plus complexes, économisant ainsi du temps et des matériaux.

If you are operating the 3D printer in a lab environment (whether it is a science lab, a design lab, or a maker lab), it would be helpful to devise a "maintenance schedule" for conducting (1) regular cleaning of the build plate as well as (2) general inspection of the extruder and the filament feeder to minimize clogging during prints. To ensure clarity and accessibility of information, both digital and paper versions of this schedule should be circulated to everyone who has access to the 3D printer and revised in accordance with operational needs.

Isopropyl and kitchen towels. If its ripping off your prints and your bp is level then its your print settings or orentation. Ideally you never want more than 45% of the surface in suction (hollow your stuff out)

The steps provided in this text, specifically regarding reattaching the build plate, aligning it correctly, securing it with screws or clamps, and recalibrating the build plate level and Z-axis height, are not directly applicable to RepRap 3D printers using filament-based technology. For RepRap 3D printers, after cleaning, the focus would be on tasks such as leveling the print bed, ensuring proper bed adhesion, and possibly adjusting the nozzle height. The recalibration steps mentioned in the context of resin-based printing are more relevant to printers that use SLA or DLP technology.

Proper reattachment ensures the plate is aligned correctly, preventing print errors. Before printing, consider running a test print to verify that the plate's cleanliness hasn't compromised print adhesion.

With Carbon’s L1 printer it comes with an extra platform, a film applicator, a spinner and a film plow. Users have the option of applying a release film that covers the platform during the print. When the print is done, the next platform is swapped in. As the next print begins, the platform is put in the spinner for a rapid dry removal of all excess resin with only centrifugal force. Parts are cured on platform before easily removing the release film and the printed parts. No scraper, no solvent, and no mess. Best of all: all the excess resin is captured in the spinner and able to be reused on later prints because it hasn’t been contaminated during cleaning.

Thoroughly cleaning a resin 3D printer's build plate is vital for successful prints and equipment durability. Wear protective gear and carefully follow these steps: remove excess resin, use high-percentage isopropyl alcohol, inspect for residue, and care for the FEP film. Dispose of IPA responsibly. Importantly, avoid tackling this task alone – always prioritise safety. Collaborative efforts and adherence to manufacturer guidelines ensure meticulous cleaning. Regular maintenance guarantees optimal performance and extends the life of your resin 3D printer. #3DPrinting #ResinPrinting #MaintenanceTips

It's important to remember that you should consider what you want to achieve from your 3D print, is it an aesthetic high quality finish demonstration model, or, a low fidelity functional prototype, for example. Is SLS the best process for you or should you consider SLA and FDM? In this case, when using SLS, although its post processing can be less intensive, the key to a successful print should always start with careful consideration to it's setup. Balance your inputs. In my experience, having an intuitive approach to 3D printing forms a great foundation to it's result. Generally speaking, the least amount of post processing the better, or at least, knowing your approach to the post processing is always best.

Once the build plate has been cleaned with Isopropyl Alcohol (IPA), it is important to ensure that any remaining resin is fully hardened. This can be achieved by exposing the build plate to an ultraviolet (UV) light source or placing it in a UV curing chamber for the recommended amount of time. This step is crucial to prevent any uncured resin from interfering with future prints and to enhance adhesion for subsequent prints. Also, Incorporating build plate cleaning into the regular maintenance routine is essential. The frequency of cleaning may vary depending on the printer's usage and the type of resin used. It is always advisable to clean the build plate after each print or as per the manufacturer's recommendations. #3DPrinting

Preventative maintenance: Regularly cleaning the build plate prevents resin buildup, ensuring smoother printing experiences. Quality of solvent: Using high-quality solvents ensures better cleaning results and reduces the risk of damaging the plate's surface. Personal experience: Over time, you'll develop your preferred methods based on what works best for your printer and resin type. Always refer to your printer's manual for specific cleaning instructions. Your experience with your printer and the types of prints you do might lead to adjustments in the cleaning process to achieve optimal results. Additionally, adhering to safety protocols and local regulations for disposal is crucial to maintain a safe and eco-friendly workspace.
