在过去的几年里，3D 打印机终于被大众广泛使用。它们不再只是专业人士和企业的工具。您甚至可以3D printers for under $500包括SLA打印机。因此，获得 3D 树脂打印机并不难，但创建具有专业外观的打印件仍然具有挑战性。
(Resin printers)AnyCubic Photon Mono X 6K等树脂打印机非常适合想要快速开始 3D 打印的初学者或想要创作详细艺术作品的艺术家。也就是说，3D SLA打印可能会像FDM打印一样出错，所以让我们探索最常见的问题并通过一些基本的 3D 打印故障排除来解决它们。
1.使用清洁树脂
通过确保使用高质量、清洁类型的树脂，没有任何残留物污染它，您可以防止许多 3D 打印问题和失败的打印。在开始新项目之前，请 务必检查您的树脂。(Always)
您可能会在瓶子内发现固化的树脂颗粒，尤其是在大量购买的情况下。固体残留物会阻止打印机正常工作，并且您的打印可能会在整个过程中出错。此外，如果您将瓶子打开，您可能会意外地用酒精或其他液体污染树脂。检查树脂并保持井井有条的工作环境。
2.检查环境温度
您可能会因为习惯而忽略家中、车库或车间的环境温度。但是，它会影响树脂的固化程度。如果您生活在较冷的环境中，这尤其成问题，因为大多数树脂要求环境温度在 22℃ 和 25℃ 之间，最好甚至更高。检查制造商的建议并加热您的工作空间或将打印机移动到您家中较温暖的地方。
在开始之前，您还应该让树脂达到室温。如果您刚收到一批新树脂，它可能比您工作区的温度更冷或更热。让它静置几个小时。您需要在打印和固化过程中保持稳定的温度。
3.保持液晶屏清洁
3D 打印失败的最常见原因之一是LCD屏幕脏污。屏幕上的任何类型的残留物都会阻止您的打印机正常工作或导致打印变形。您的打印机的紫外线必须穿过屏幕而没有任何东西阻挡它的路径，否则您的模型会出现间隙和其他缺陷。
您必须处理的最常见残留物是固化树脂，因为在 3D 打印中事情很少会完美。要清洁它，请使用塑料刮刀。您也可以使用锋利的剃须刀片，但请小心轻柔地使用，否则可能会损坏屏幕。大多数残留物应该很容易脱落。如果之后屏幕仍然有些脏，请用超细纤维布和异丙醇擦拭。
4.不要打印得太快
损坏 3D 树脂打印的一个常见原因是打印速度过快。3D 树脂打印通常涉及使用紫外线照射树脂使其硬化。树脂需要受到正确数量的光照射，否则您将得不到任何结果。打印太快意味着您的打印件曝光不足，或者换句话说，树脂没有得到足够的紫外线。结果，您的打印机不会打印任何东西，如果打印了，您将拥有一个容易损坏的脆弱模型。
进入切片机软件并调整打印设置，尤其是打印速度。以小幅度减慢打印速度，然后重试。另外，记得先检查树脂和温度。
5. 45度对角打印
3D 树脂打印的不成文规则是以 45 度角打印模型。为什么？以一定角度打印可以减少故障并提高打印质量，尤其是在由于打印模型较大而需要大量支撑结构时。
当您垂直打印时，模型的重量会更重地压在支撑上，因为重量分布不均。一切都垂直流动。通过对角线打印，重量分布更均匀，因此您面临的支撑问题更少。作为额外的奖励，您还可以更轻松地从构建板上移除打印的模型。
6.不要超载打印床
打印可能需要很长时间，因此您可能在某个时候决定用尽可能多的模型填充构建板。毕竟，为什么不一次打印所有内容来节省时间和金钱呢？好吧，您最终可能只会打印失败并浪费大量树脂。
如果您是初学者并且犯了错误，那么打印床上的所有模型都可能出错。根据型号的不同，您的 3D 树脂打印机甚至可能无法在构建板过载的情况下正常运行。因此，坚持一次打印一个或最多两个 3D 模型，并记住将它们保持在 45 度角，以增加成功的机会和打印质量。
7. 检查FEP(FEP Film)薄膜并更换(Replace)
FEP薄膜是一种特殊的箔片，用于为 UV 光源固化树脂创造最佳路径。它是印刷过程的重要组成部分。如果您的打印突然变成失败，您需要检查胶片。它经常被忽视，尤其是初学者。
经过一定量的印刷后，FEP薄膜会翘曲或遭受某种损坏。当您发现此类磨损迹象时，是时候更换它了。小划痕不会影响打印质量，如果发现污迹，您可以忽略它们或用纸巾和异丙醇擦拭它们。
8. 重新校准构建板
如果您的打印结果在第一层、较低层或中途完全失败，则构建板可能会略微倾斜。作为打印机日常维护的一部分，您需要将其调平并在必要时重复此操作。无论您使用的是树脂 3D 打印机还是FDM打印机，校准都是避免大多数 3D 打印问题的关键。
根据打印机的质量，它可能需要比其他打印机更频繁地重新校准。也就是说，所有 3D 打印机都需要时不时地进行一些校准。查看 3D 树脂打印机手册，了解如何调平打印表面并将其恢复到最佳位置。
9. 处理分层
细丝印花并不是唯一可能最终看起来变形的印花。例如，构建模型所需的树脂层可能无法很好地粘合，它们会以不同的方式移动，看起来好像它们正在相互拉开。这种层分离被称为分层，它肯定会破坏您的打印外观，因为它太明显以至于无法注意到。幸运的是，您有 2 个解决方案。
生成更多支持结构(Generate More Support Structures)
如果没有得到适当的支持，树脂印刷品可能会出现很多问题。因此，请确保您有足够的支撑来支撑模型中处于大角度的部分。此外，请记住将模型以 45 度对角定向，以增加支撑的弹性和打印质量。
寻找障碍物(Look for Obstructions)
(Layer)当有东西阻挡紫外激光的路径时，也会发生层分离。首先(First)，您需要确保树脂本身是干净的，没有任何碎屑阻挡或干扰光线。如果您注意到任何固化树脂，您可以使用过滤器去除任何固化树脂。之后(Afterward)，查看FEP薄膜和LCD屏幕是否有任何标记、缺陷或碎屑。清洁(Clean)所有污染物并更换损坏的薄膜。
10. 处理蹂躏
Ragging是另一个 3D 打印变形问题，它会将您的模型变成一个满是斑点的丑陋烂摊子。看起来像薄襟翼的渗出状架子水平地从您的打印件中提取出来。这些薄结构通常在树脂槽内部分固化并脱落，从而阻碍紫外线激光并破坏无法挽救的打印效果。以下是解决此问题的方法。
检查树脂(Check the Resin)
树脂过期了吗？您是否(Are)在使用来自阴暗来源的便宜得难以置信的树脂？根据树脂的不同，它的使用寿命有限，可以从 1 年到 2 年不等。过期的树脂不可靠，并且会对紫外线激光、环境温度和其他变量做出不同的反应。储存不当(Improper)也会使树脂降解。
在任何一种情况下，像粗糙这样的打印变形是树脂不良的常见结果，因此请务必检查它。
寻找障碍物(Look for Obstructions)
与分层一样，受阻的激光可能是导致粗糙问题的原因。检查树脂桶是否有碎屑。用塑料刮刀彻底清洁打印床。从罐中取出树脂并过滤，以防里面有任何固化树脂。此外，检查FEP薄膜并清洁所有光学表面。
减少支撑数量(Reduce the Number of Supports)
太多的支持可能是一件坏事并破坏您的印刷品。粗糙(Ragging)是高支撑密度的症状，因此请检查切片器软件中的设置以减少支撑数量。通过重新定位您的模型，使您的支持更有效。如前所述，45 度角将减少您需要的支撑数量。

10 Troubleshooting Tips for 3D Resin Prints Gone Awry
In the last few years, 3D printers have fіnally become wіdely aνailable for the masses. They’re no longer tools just for professionals and businesses. You can eνen find great 3D printers for under $500 including SLA printers. So getting a 3D resin printer isn’t difficult, but creating a professional-looking print can still be challenging.
Resin printers like the AnyCubic Photon Mono X 6K are ideal if you’re a beginner who wants to quickly get started with 3D printing or an artist looking to create detailed art pieces. That said, 3D SLA prints can go wrong just like FDM prints, so let’s explore the most common problems and fix them through some basic 3D printing troubleshooting.
1. Use Clean Resin
You can prevent a lot of 3D printing issues and failed prints by making sure you use a high-quality, clean type of resin without any residue contaminating it. Always check your resin before starting a new project.
You might find cured resin particles inside the bottle, especially if you buy large quantities. Solid residues can prevent the printer from working properly and your print might go awry halfway through the process. Also, you can contaminate the resin accidentally with alcohol or other liquids if you leave the bottle open. Inspect the resin and keep a well-ordered working environment.
2. Check the Ambient Temperature
You might ignore the ambient temperature in your home, garage, or workshop simply because you’re used to it. However, it can impact how well the resin sets. This is particularly a problem if you live in a colder environment because most resins require an ambient temperature of between 22℃ and 25℃ and preferably even higher. Check the manufacturer’s recommendation and heat your workspace or move the printer to a warmer part of your house.
Before getting started, you should also let the resin reach room temperature. If you just received a new batch of resin, it’s probably colder or warmer than the temperature in your workspace. Let it sit for a few hours. You want a stable temperature during the printing and curing process.
3. Keep the LCD Screen Clean
One of the most common reasons for failed 3D prints is a dirty LCD screen. Any type of residue on the screen can prevent your printer from working properly or cause print deformations. Your printer’s UV light has to go through the screen without anything blocking its path otherwise you’ll get gaps in your model and other defects.
The most common residue you’ll have to deal with is cured resin because things rarely go perfectly in 3D printing. To clean it off, use a plastic scraper. You can also use a sharp razor blade, but please use it carefully and gently or you might damage the screen. Most of the residue should come off easily. If the screen is still somewhat dirty afterward, wipe it with a microfiber cloth and isopropyl alcohol.
4. Don’t Print So Fast
A common cause of ruined 3D resin prints is a high printing speed. 3D resin printing usually involves the use of a UV light that hits the resin to harden it. The resin needs to be hit by the correct amount of light or you won’t get any results. Printing too quickly means your print is underexposed, or in other words, the resin doesn’t get enough UV light. As a result, your printer won’t print anything and if it does, you’ll have a frail model that breaks easily.
Go into the slicer software and adjust the print settings, especially the printing speed. Slow the printing down in small increments and try again. Also, remember to check the resin and the temperature first.
5. Print Diagonally at 45 Degrees
The unwritten rule of 3D resin printing is to print your model oriented at 45 degrees. Why? Printing at an angle results in fewer failures and better print quality, especially when a lot of support structures are needed due to a large print model.
When you print vertically, the model’s weight presses harder on the supports because the weight isn’t distributed well. Everything flows vertically. By printing diagonally, the weight is spread more evenly so you risk fewer support problems. As an added bonus, you’ll also have an easier time removing the printed model from the build plate.
6. Don’t Overload the Print Bed
Printing can take a lot of time, so you probably decided at some point to fill the build plate with as many models as possible. After all, why not save time and money by printing everything at once? Well, you might end up with nothing but a print failure and waste a lot of resin.
If you’re a beginner and make a mistake, all of the models on the print bed can go awry. Depending on the model, your 3D resin printer might not even operate well with an overloaded build plate. So stick to printing one 3D model at a time, or a couple at most, and remember to keep them at a 45-degree angle to increase your chances of success and the print quality.
7. Check the FEP Film and Replace It
The FEP film is a special foil used to create an optimal path for the UV light source to cure the resin. It’s a vital component of the printing process. If your prints are suddenly turning into failures, you need to check the film. It’s often overlooked, especially by beginners.
After a certain amount of printing, the FEP film will warp or suffer some kind of damage. When you spot such signs of wear and tear, it’s time to replace it. Small scratches won’t affect the quality of your print, and if you spot smudges you can ignore them or wipe them with a paper towel and isopropyl alcohol.
8. Recalibrate the Build Plate
If your print turns out bad at the first layer, the lower layers, or it completely fails halfway, the build plate might be slightly inclined. You need to level it and repeat this operation whenever necessary as part of your printer’s maintenance routine. Whether you’re using a resin 3D printer or FDM printer, calibration is key to avoid most 3D printing problems.
Depending on the quality of your printer, it might require recalibration more often than others. That said, all 3D printers need some calibration every now and then. Check the manual for your 3D resin printer on how to level the print surface and bring it back to its optimal position.
9. Dealing with Delamination
Filament prints aren’t the only ones that can end up looking deformed. For example, the layers of resin needed to build models might not bond well and they shift in separate ways looking as if they’re pulling apart from each other. This layer separation is known as delamination and it will definitely ruin the looks of your print because it’s too obvious not to notice. Fortunately, you have 2 solutions.
Generate More Support Structures
Many things can go wrong with a resin print if it’s not properly supported. So make sure you have enough supports to hold the parts of your model that are at a drastic angle. Also, remember to orient your model diagonally at 45 degrees to increase the resilience of your supports and the quality of the print.
Look for Obstructions
Layer separation also occurs when something is blocking the UV laser’s path. First, you need to make sure the resin itself is clean, without any debris blocking or interfering with the light. You can use a filter to remove any solidified resin if you noticed any. Afterward, look at the FEP film and the LCD screen for any markings, imperfections, or debris. Clean all contaminants and replace the film if it’s damaged.
10. Dealing with Ragging
Ragging is another 3D print deformation problem that turns your model into an ugly mess full of blobs. Oozing-like shelves that look like thin flaps stem horizontally from your print. These thin structures are often partially cured and break away inside the resin vat, thus obstructing the UV laser and ruining the print beyond salvage. Here’s how to troubleshoot this problem.
Check the Resin
Is the resin expired? Are you using too-cheap-to-be-true resin from shady sources? Depending on the resin, it has a limited lifetime that can range from 1 to 2 years. Expired resin isn’t reliable and will react differently to the UV laser, ambient temperature, and other variables. Improper storage can also degrade the resin.
In either case, print deformation like ragging is a common result of bad resin so make sure you inspect it.
Look for Obstructions
Same as with delamination, an obstructed laser can be the cause of the ragging problem. Check the resin vat for debris. Clean the print bed thoroughly with a plastic scraper. Remove the resin from the tank and filter it in case there’s any cured resin inside it. Also, inspect the FEP film and clean all optical surfaces.
Reduce the Number of Supports
Too many supports can be a bad thing and ruin your print. Ragging is a symptom of high support density, so check the settings in the slicer software to reduce the number of supports. Make your supports more effective by also reorienting your model. As mentioned earlier, a 45-degree angle will reduce the number of supports you need.
