So your new 3D printer just came in the mail, but do you know how to use it safely?  It today’s article, we’ll discuss what you need to know in order to use your SLA printer safely.  This video is a follow-up to the previous SLA printing Basics article.

To begin, it’s very important to know that even if you’re using a plant based resin, they do still contain products which can trigger severe allergic reactions after prolong exposure. This exposure includes both the vapours and the liquids themselves, as well as their cleaning agents. Despite the fact that some have low amounts of odour, the fumes are still present in their environment, therefore proper precautions are still necessary. While new products are being developed by many companies to address these issues, it is best to treat them as the chemicals that they are. Waste disposal is a very common issues for those new to this hobby, as it can often be overlooked and can cause serious long term environmental impacts.

To better address any fumes from these products, it’s always best to have a well ventilated area with a constant supply of clean air, and there are a couple of ways to do this. The first is having ventilation going to the outside and while this is very efficient it may not be possible in colder environments. I personally use multiple carbon filter’s both within my machines and on the outside to help mitigate these issues. This, alongside a slightly open window in my work areas, helps to maintain a supply of clean fresh air. By making sure to keep the cover on your machine closed, and dealing with any liquid messes properly, you can maintain a much safer environment. This can be especially true if you have children or pets. In this case, you should always have these machines in a secured location to prevent any accidental exposure.

When it comes to the handling of the resin liquid itself, safety glasses and gloves are a must-have. I use two different types in my workflow. I use disposable ones when I’m working on something that requires more hand dexterity, and I use re-usable long sleeved rubber gloves for the basic print remove process. Likewise, I find that hanging this above my silicone mat helps keep a cleaner environment, especially if I clean the gloves prior to hanging them. By using a piece of paper tower, I can easily remove these without touching the top rim and can hang these safely. If you happen to get it on your skin, make sure to clean the area thoroughly with soap and water. To clean up any messes, I will use paper towels, making sure to place these out in the sun to cure any leftover resin. Because UV resin is cured in sunlight, you may wish to protect your machine from any of the sunlight coming from the window itself. I use blackout curtains and have an additional curtain around my work area to help mitigate the issue. IF you’re living in a location where you don’t have access to reliable sunlight, you can use a metal bucket and suspend a UV light above it to cure any unwanted resin. I got this one at my local hardware store and picked up this barbecue rack which works great for suspending the UV light. I go through a lot of paper towels for clean up, so I generally try to do larger batches to make my workflow more efficient. Having a paper towel dispenser makes a big difference when your gloves are covered in resin, and I would highly recommend either 3d printing one use using one that’s pre-made for this purpose.

As for cleaning up any messes that you may have, in most cases you’re going to use 99% isopropyl alcohol if possible. While you can use up to 70% it’s normally a better value to get the higher concentration and dilute it yourself. Although you can now buy less toxic alternatives, you’ll most likely want to keep using isopropyl alcohol for the cleaning of your work area, since it doesn’t leave any residue and dries quickly. For cleaning your prints, isopropyl alcohol can be reused several times if allowed to sit and separate. You can use a siphon pump to remove the clean isopropyl alcohol from the top of your container and dispose of the dirty material by letting it cure in the sunlight. To make your clean-up easier in the long term, I personally use multiple silicone dog mats, which I’ve placed in all of my work areas. Because the resin doesn’t stick to it’s surface, it makes cleanup a lot easier overall.

Now, It’s important that I tell you that some of these 3d printers have tinned connections at their terminals. This is something which I’ve actively warned user’s about and is something you may wish to check on your machine. Some companies have started taking a proactive approach with this and have been removing the tinned portions or replacing these with proper connection and ferrules, however some companies have yet to do so. I’ve noticed that some of the more recent machines from both Anycubic and Elegoo have addressed some of these, but I would do some additional research to see if that’s the case with your machine. You can see my full safety article here about what to look out for in some of the most common 3d printers.

In today’s article, we’ll be looking at modifying your Resin Printer lid to make it more space efficient.   As always, do this modification at your own risk, and I’m in no way responsible if any damages may occur.

I, like many others, had pre-ordered the Elegoo Saturn 2, and although I had received it some time ago I was unable to use it because of space restrictions.  In my case, this was caused by the lid design which, although fairly robust, requires several inches to properly remove the cover.  It’s for this reason that I started working on this simple modification for my machine.  To make these changes easier, I’ve reworked the initial design to ensure that the original lid could be reused and that only a limited amount of printing would be required.  This makes it easier for more people to undertake, while also leaving additional room for customization in the future.  Now I will be including the tools, supply list and STL on the main website at should you also be interested in doing this yourself.

Before undertaking this, you’re going to want an easy to clean space, since this will create a lot of debris which will be difficult to clean up latter.  So I’d highly recommend you have a vacuum at the ready since this debris could damage your FEP if it gets into the vat.  You’ll need a rotary tool kit along with a cutting disk that will be large enough to cut through the full thickness of the material. Having a Back saw will help cut all the way through if you don’t have the proper disk thickness, and will also help straighten the cut.

Before we start cutting, we’re going to place some painter’s tape along the edge of the machine. The cut will be at 2.5 inches from the back of the lid, so you’ll want to cover that area, so you can make your markings.  With the Painter’s tape in place, you’ll then either use a combination square or a simple ruler to draw out your lines.  As mentioned previously, I made it 2.5inches from the back of the machine so that it just barely cleared the linear rail system.  It’s very important that you clear the rail system, which we’ll be attaching the printed portions to this latter.

Before cutting into the materials, I did some practice runs with a similar plastic to make sure I had the proper speeds for my rotary tool kit.  In my case, I found that a speed of either 3 or 4 was a great balance between speed and control.  Anywhere past the 5 mark and you will risk melting the plastic, which can cause the disk to melt into place.  The cutting disk I was using, was fairly small therefore it didn’t cut all the way through, forcing me to use my Back saw to finish the procedure.  This had the additional benefit of straightening out my cuts, but shouldn’t be necessary if you have the correct supplies.  I began from one side, going all the way around, making sure that I was always facing the backside of the lid.  This helped ensure that I always cut from the same side of the markings.  Once I finished both sides, I then worked on the top of the lid, being very careful not to put too much pressure on it.  While finishing up with the Back saw, I made sure to hold both portions together while I cut through.  

With the two pieces cut, It was time to deburr the edges and clean the entire area before moving forwards.  This is actually a very important step since material can get stuck in the tape and become difficult to remove later on.  I used a vacuum cleaner to clean the workspace and the lids fully.  Although the lid could fit currently together, it’s better to add a ledge to prevent any light from bleeding through.  Any fully opaque thin plastic will work for this purpose.  I had some material lying around, so I used this, however most art or hardware stores have various materials which could be used for this purpose.  Just make sure whatever you choose will be resistant to isopropyl alcohol and the resin. To attach this material, you’ll have two main options.  You can use a double-sided adhesive or, like me, I used Gaff tape since it doesn’t leave a residue.  If you do decide to use Gaff tape, be aware that you’ll need to replace it every 1 to 2 years.  By putting this tape on both sides of the edge, it allowed for a tighter fit, which in turn prevents the front from coming off as easily.   I did leave about 1 inch clear from the bottom since I was concerned about the tape absorbing resin.   I ended covering that area later on because it allowed too much light through the openings on either side.  What I did do, however, it uses kapton tape to attach the material to that area since it’s more resilient to chemicals.

After 3d printing these two parts, we’ll superglue this to the top of the Linear rail enclosure.  This will help make sure that the back lid stays in place, since we don’t want this to move around. Using some more Kapton Tape, we’ll tape the bottom edge of the lid to the rest of the machine.  With everything attached, I could finally start testing this new machine.  

So while this may not be necessary to get a fully functional machine, this mod has made a big difference in my ability to fully utilize my work space. Removing the lid is a lot easier now and has speed up my overall workflow.  I hope you guys enjoyed this video and I hope to see you guys again soon

What is It?

Unlike FDM printers, SLA one’s function quite differently depending on the type that you’re using.  In today’s article, well go over the basics of what an SLA printer is and how it works.

Although there are multiple types of resin printers, today we’ll be focusing on SLA one’s since these are the most common types found in households. These types of printer’s can actually come in 3 different varieties, with the most affordable being the LCD based version. All of these printers use a resin which cures when exposed to a UV light and stores this resin within a container called a vat. The vat itself has a transparent film on the bottom, which allows the resin to be exposed to the light source. DLP, also known as digital light processing, uses a Projector to expose the resin to UV light. LCD or MSLA resin printer’s, use a UV light source in conjunction with an LCD to help cure the resin. Both DLP and LCD printers, cure each layer simultaneously, making them faster when fully utilizing the build plate. Although the term SLA is used as an umbrella term for all of these types, it’s more specifically used to describe stereolithography based printers which use a laser to cure the resin. While these laser printers can potentially produce better levels of details, they can take much longer to complete depending on how much of the build plate is being utilized. Almost all the lower cost resin printers on the market today will be the LCD or MSLA printers, so these will be the ones we’ll be covering today.

The best way to understand LCD resin printers, is to see them as working similar to screen printing. Each object is made up of several different layers of exposed resin. Each layer is created by shinning a UV light source through the base of the machine, while the LCD masks out any areas which shouldn’t be exposed. This means that it can cure many objects simultaneously without taking additional time. As each layer is cured, the machine will lift before going back down into the next position for the next layer. Originally these printers used RGB screens which were similar to that of a tablet but because of the efficiency, speed and longevity, they have since been replaced with mono screens for the most part. The RGB stands for the Red, Green and Blue filters which create a black mask, while the mono screen uses just the one layer instead. These new screens allow more of the UV light through because it doesn’t need to go through as many filters. RGB screens create coloured images, while the mono one only create a grey scale one.

The layer thickness, determines the resolution of the print it in the Z axis. The resolution of the X and Y are determined by the screen resolution. Although many machines are described as being 2k or 4k in resolution, a better method of determining the potential of the machine is to calculate the pixels per inch instead. IF you have a 4k screen that’s 8 x 6 inches and boasts a pixel count of 3840×2160, this will actually be a lower resolution than a 5 x 3 inch display with the same pixel density. The reason for this is that you are dividing the pixels to the overall size of the screen. So in order to get a measurement that’s easier to compare, you divide the pixel count by the size instead. Not all companies will readily make this information available, but a quick search on the manufacturer’s website can normally give you the number’s to calculate this.

Safety is a high priority when dealing with these machines, and that’ll be something we’re going to cover more thoroughly in the next article. When that one’s made available, you will see the link HERE.

Screen Types

  • RGB = Red + Green + Blue = Colour
  • Mono = Black Opaque = Greyscale


  • Pixels per inch
  • Pixel size ÷ size in inches

Every machine runs off of firmware, and the Anycubic Mono X is no different.  While in most case, updating the firmware isn’t necessary, it can sometimes address certain issues that come stock with the machine.  In this article, we’re going to go through the process for this particular machine.  As always, there’s a certain element of risk involved when doing, so I’m in no way responsible if any damages may occur.  

Updating the firmware is important for a couple of main reasons. If you’re upgrading the free license of Chitubox from an earlier 1.8.1 version, then this update will make it compatible with the software.  These updates also help address some common bugs and on other machines that can sometimes included additional functionality. 

Before updating anything, you’ll first need to reformat a USB stick to make sure there’s nothing can can interfere or cause issues. In windows, you’ll right-click this drive and select the format option.  In this case, we can simply use the Quick Format while making sure it’s set to FAT32.  Once completed, we can then begin downloading the files.

Currently, there are two versions of the firmware for this particular machine, and they currently come bundled together when you download them from the main website.  Luckily, Anycubic realized this could cause issues and made it so that only the correct version would install, so long as the proper order is followed.  Going to the main website, you’ll download these by going to, 3D Printers + Photon Series + Mono X. You’ll then scroll all the way down until you reach the firmware section where you’ll be able to download the package.  Be very careful about installing these files in the correct order.

Once you’ve unzipped the files, you’ll notice 4 files within the folder.  There’s the ReadyMe document along with the 3 firmware files.  You’ll transfer the .bin files to the root director of the USB stick and plug it into the Machine.  In order to run these updates, we need to print them.  So we’ll first Print the P_MXV5_4_0812(1).bin file.  It’s important to start the update process with this file, otherwise you may run into issues.  After confirming that you want to update, the process will begin and the machine will be restarted.  This can take a couple of minutes, so be patient. With the first part is completed, you can then run the remaining two updates.  Only one of these two files will work, the with one will be showing an error. With the update completed, you’ll remove the USB stick and restart the machine to make sure that everything has been enabled.  I personally didn’t need to change any of my settings after doing this update, however your millage may wary.

Unlike many of the original machines, this one lacks a protective glass layer to protect it from spills and damages.  To keep your machine in good working order, you can view this article here for information on how to protect your machine’s screen. Protect your LCD Screen
