Ways To Minimize Toxic Injury
- Wear Gloves you must always wear gloves when operating a resin 3D printer to ensure your skin never accidentally makes contact with the uncured resin. Do not re-use gloves. You must use new gloves every time you touch uncured resin.
- Place Disposable Cooking Sheet Beneath Printer in the event something goes wrong, and the uncured resin spills everywhere, you want it contained and easy to dispose of. Most importantly, you dont want it present on any random surface where you might not see it and later touch it.
- Wear Safety Goggles in case any resin splashes, you dont want toxic liquids coming in contact with your eyes.
- UV Cure Any Uncured Resin Pieces when you clean out the uncured resin parts inside the 3D printer, you must cure the resin by applying UV. To do this, you can set the part out in the sun or under a UV nail dryer

What Is Resin 3d Printing
Resin 3D printing, or SLA 3D Printing, is the process by which liquid resins are cured or hardened layer-by-layer using a laser , LCD screen , or digital light projector .
SLA 3D printers are capable of incredibly detailed 3D prints at a high resolution without the easily visible layer lines typically associated with FDM 3D printing. Once an SLA printed part is complete, it must be post-processed in UV light.
The high precision of SLA 3D printed parts makes resin a popular option for printing small, finely detailed models such as dental models, medical models, jewelry and even miniatures.
Uv Resin Deserves Respect Not Fear
Photopolymer resin is a fantastic tool for all of our creative and functional adventures, but like most things in life, it is only good in moderation. Working with UV resin implies that we will breath some in and get a bit on us at some point in time – the goal is to just reduce this as much as practically and economically possible. Wearing nitrile gloves prevents skin contact, having the printer in the garage prevents 24/7 exposure, wearing a respirator while interacting helps protect our lungs, and properly cleaning + curing + sealing/painting prints increases handling safety.Everything can kill us, even the thing we are made 60% of. It is important to be informed that way we can respect the world around us instead of being consumed by fear or ignorance. In my personal life, I have spent a good chunk of my time in a house with interior lead paint and exterior asbestos siding, but my lead blood levels are good and I’m asbestos-free … I hope – kidding aside, the asbestos panels are outside the house and stable unless they are drilled into or ripped off the wall.

Storage And Usage Guidelines
Always wear appropriate safety equipment, such as 100% nitrile gloves, when handling uncured resin. Protect your body from any direct contact with uncured Figure 4 resin.
- Always read the Safety Data Sheet prior to use of any Figure 4 resin.
- Always use the oldest resin bottle first. All resins have a shelf life. Using the oldest resin first helps you to use all your purchased materials within that period of time. The expiration date of a resin will be printed on its bottle.
- During storage, shield the resin from sunlight or other sources of actinic radiation, such as fluorescent or mercury vapor lights. Exposing the resin to UV radiation increases product viscosity and chance for polymerization, making the resin unsuitable for part building. Storing resin above the maximum recommended temperature can also make the resin unsuitable for part building. Resins should be stored in the opaque, UV-resistant bottles they came in. If you must store resin in the resin tray outside the machine, store the tray in its garage with the UV-protective lid. Inside the Printer, the resin in the resin tray is largely protected by the orange acrylic door. Also, your 3D Systems installer will not install the machine close to sources of UV radiation.
- Store bottles of Figure 4 resins indoors at temperatures between 5°C-30°C . Storing at temperatures below this minimum or above this maximum could render the resin unusable for part building.
Where To Find The 3d Print Files For Miniatures
All you need now is to find the files to print.
My favourite database for miniatures and other similar objects is My Mini Factory.
Many companies sell their product there and you can even obtain monthly subscriptions where you subscribe for a fixed price every month and in exchange you get all miniatures released by that company that month and a discount on that company store on the same site .
This concept is similar to Patreon, where many companies have different reward tiers and provide different types of miniatures .
One of the biggest perks of My Mini Factory is that all your 3D printing files are stored there so you do not have to worry about having those precious files on your own drive.
Another popular site with plenty of free content is Thingiverse. There are other sites out there, so you can do a search for anything in particular, if for example you have Gloomhaven and you want to go the next step and 3D print all miniatures available, Thingiverse can definitely help you out!
Just remember: it will be much easier for you if you find files that are pre-supported.

Resin 3d Printing Drawbacks
While resin 3D printing offers compelling advantages, there are still a few things you may want to keep in mind.
- Material prices Resin can be expensive, especially if the system you choose doesnt work with third-party resins.
- Post-processing Prints must be washed and then cured with UV light or sunlight. Most manufacturers sell separate, dedicated stations for these steps to make them less troublesome.
- Toxicity Its important and necessary to wear gloves, and working in the same room as an active resin 3D printer is highly discouraged.
How To Cure Uv Resin
At first, you may need to take a lot of factors into account in order to estimate its curing time.
The thickness and size of the items you print will decide how much time the material will take to cure.
Each layer of a small piece, such as jewelry, takes 2 to 3 minutes to cure. On the other hand, larger pieces and layers will need from 4 to 6 minutes.
Humidity and room temperature can also affect this period.
You should note that while the sun does produce UV rays, they are not powerful enough to harden your resin.
As a result, you will need a specific UV resin-curing light bulb. Moreover, you cannot use just any UV light because it needs to be of the right setting in order to harden the glue.
Most UV resins require a wavelength range of 356 to 400 nanometers to get firmed.
You have to cast this sort of material in thin layers to make sure that the glue is sufficiently hardened.
Each layer should be no more than 3 mm thick, and you should let each one cure completely before moving on to the next.
While UV resin is ideal for smaller jobs and provides quick results, the end result is not as durable as epoxy one.
UV one is different from the epoxy resin in that it is not heat or scratch-resistant. Besides, it does not last as long as the epoxy material.
Is Uv Resin Safe For Skin Resin Usage & Health Risks
You may already know what is UV resin. It is a common material that can be used in the 3D printing method. However, have you ever wonder is UV resin safe for skin and even your health or not?
Although this material is widely used, the health risks linked with it are not much discussed.
UV resin can be quite dangerous, yet few people are aware of its dangers.
Using this material for 3D printing can cause some further risks.
This article will tell you why it is so poisonous.

Epoxy Or Vinyl Ether Is Safer Than Acrylic And Methacrylic Based Resins
The majority of MSLA resins utilize free-radical polymerization. Epoxies, vinyl ether, and propenyl ether can utilize cationic polymerization, and they are less toxic2,11,12. Some other advantages include: the ability to continue curing once the UV source has been turned off, better chemical resistance, higher HDTs, volumetric shrinkage of 2-6%, and the potential for faster curing times11,12.The main downside is that the cationic resins are expensive for now – general vinyl ether resin is ~$40 per liter. Another deal-breaker for many applications is that current blends of epoxy resin are rather brittle11. More research and development is needed in order to eventually bring commercially viable resins to market.

Cost Of The Materials
FDM printers use filament spools that are relatively cheap and can last for a long time. The overall throughput of a FDM printer is higher than a resin printer meaning more quantity hence less costs.
Resin bottles are usually more expensive than plastic filaments and last much less depending on what you are printing. A single bottle for example can print two warbands of Bloodfields, including bases. A warband will usually have at least one centrepiece of considerable size, 1-2 medium sized characters and 5-8 smaller fighters.
Do You Need To Wear A Mask When Using Uv Resin
A mask is not required when 3D printing with UV resin, but it is highly recommended for safety reasons. You can get yourself eco-friendly resin like the Anycubic Plant-Based Resin. A 3M respirator with an air purifier is a great combination to increase safety.
When you buy a 3D printer, they usually come with gloves and a mask for safety, so we know its recommended by manufacturers.
Usually, the smell of the resin is bearable, the main thing that requires us to wear a mask while printing is the fumes that are emitted from the resin. A simple facemask works pretty well.
You can get yourself the from Amazon.
Some resin smell pretty bad and if you are sensitive to smell then you should always wear a mask before initiating the printing process.
The resin my Anycubic Photon Mono X came with smelled really harsh, so a mask was needed for operation. When I got the Anycubic Plant-Based Resin, as talked about above, the odor was very bearable and easy to handle.
Resin fumes have particles and molecules that can be harmful to the body especially if you do 3D printing regularly.
Inhaling the resin particles via fumes may cause allergy, irritations and may also lead to negative health implications in the longer-term future.
The resin used for 3D printing has a clear warning that it is toxic and not food-safe therefore experts suggest wearing a mask or respirator for safety purposes.

Is Anycubic Resin Toxic
Anycubic resin is a plant-based resin that is used for 3D printing. It is not as toxic as compared to other resins, but still toxic as a resin. Although the Anycubic Plant-Based Eco Resin has a low-odor, you still want to avoid contact with skin.
- As it is made up of natural ingredients such as soybean oil, it has no VOCs or any other harmful chemicals.
- Emits a low odor and is easy to work with.
- Biodegradable and eco-friendly
- Provides less shrinkage that helps in getting better quality prints.
- The prints come in a fresh color and look great.
Where most of the people claim that they feel normal, a few users have also claimed that they had headaches after working with resins that have a heavy odor. Anycubics normal resin is part of that group, so Id recommend their plant-based alternative.
There are different opinions in this regard but we suggest you follow precautionary measures because it is better than being sorry after getting hurt.
Therefore, it is recommended that:
- You place the printer in a place away from your main living areas such as in your garage or dedicated workplace.
- The resin doesnt make contact with your skin because repeated exposure to the skin can cause irritation and allergic reactions.
- Wearing gloves is an essential rule that you should always follow

Other Ways To Improve Air Quality When Using A 3d Printer
The most important step to take when using a 3D printer is to use adequate ventilation. Because a 3D print run can take hours or even days, this probably requires something beyond an open window. A proper vent fan exhausting to the outside will draw VOCs and particles out of the house, keeping your air cleaner.
As a greater understanding develops of the potential hazards of using 3D printers, new plastics and base materials are being developed that produce VOCs and UFPs in smaller amounts. Choosing low-emission base materials can also help with your indoor air quality.
Using the 3D printer inside a HEPA filter-equipped enclosure is a proven way to make them safer. However, very few 3D printers are currently sold with enclosures included. Adding a HEPA enclosure to your workshop is a great way to prevent many of the air quality issues caused by 3D printers.
As 3D printing technology becomes more available and affordable, so too is our understanding of its effects on indoor air quality and our health. Therefore it is crucial to make an informed decision when selecting an air purifier to help maintain a safe indoor environment if you have a 3D printer in your home or workspace.
Is Uv Resin Safe For Skin
No, liquid resin is poisonous and can be absorbed through the skin.
It is dangerous to ones health.
Not only does this have a bad impact on your health, but it also has an impact on the printing industry as a whole.
Many people do not notice that when resin comes into touch with their skin because it does not cause any significant responses at that time.
You may not see anything or feel any pain or burning.
However, if you come in contact with resin or its gas for a long time, your body will eventually become extremely sensitive to it.
This develops gradually like getting an allergy
. Resin causes the skin to react strongly over time.
The presence of just a few fumes in the air is enough to cause severe headaches.
In industry, a lot of manufacturers choose this substance.
It is because of many unique applications that can be applied to modern life.
Occupational safety has long been taken into account because interaction with this glue is bad for peoples health.
