Step 1 Start the water before you start pouring the alcohol. However, rubbing alcohol typically contains 70 percent isopropyl alcohol. Then get an empy jellycan and cut open huge cola bottle at the bottom, put coffee filter at the opening (with cable tie) and pour isopropyl down. NOTE: Don't use varsol, vinegar, alcohol or acetone to clean your hands. No more than 3% by weight of the total capacity of the container should remain inside of it at the time of disposal. Clean up resin or mixed epoxy with acetone, lacquer thinner or alcohol. Safe and appropriate disposal methods of used IPA vary by location. Overexposure can lead symptoms such as headaches, dizziness, nausea, and vomiting. Once the resin has cured and dried, the only way to break it down is to let it soak in acetone or rubbing alcohol. When it comes to washing, swirling, and dipping your prints in that IPA, the residue can easily collect onto your prints. Note: Most Formlabs resins can be washed in IPA with a concentration of 90% or higher. Not recommended for strong oxidizers . When disposing of empty resin and hardener containers, make every attempt to empty the container. There is a pot time to the resin (period of time that the resin is still liquid enough to work with) versus curing time (the amount of time needed for the epoxy to completely harden).

In some cases, it’s unavoidable and you will need to add more into the vat while you have a print running, just because your print consumes an entire vat’s worth of resin. Handling IPA Practice safety when using Formlabs products. Handling resins safely will prevent you from accruing toxic substances over time. Image lightbox. /r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing. For those that are not familiar with SLA printers, one of the steps in finishing a model is to clean it in isopropyl alcohol (IPA). If the UV curable resin is in a pourable bottle, carefully pour the liquid from the storage bottle into the printer tray, avoiding spills and drips. With SLA printers, the liquid resins that are hardened to make the 3D prints are a bit more hazardous. IPA specifically could be more of an issue though as it absorbs water/loses the alcohol. Denatured alcohol has a plethora of uses for home and industry. Disposing of containers without treating them first could allow chemical runoff to mix with groundwater, seep through soil, and eventually get consumed, harming humans and wildlife. This protects the wood from scratches and UV rays, and also gives it a mirror-like finish. To dispose of smaller amounts, pour into a disposable tray and leave it outdoors in sunlight. IPA dissolves uncured resin, which the model is covered in as it's extracted out of the resin tank during build. There are many different ways in which ethanol can be denatured. DO NOT dispose of hardener in trash containing sawdust or other find cellulose materials―they can spontaneously combust. You can filter used alcohol and reuse it some if you like. As mentioned previously, you can funnel and re-use excess resin. Then poor that isopropyl alcohol and resin mix into a container that you can leave out in the sun or under a UV light to dry and harden. Because ethanol is highly flammable and combustible, there are a couple of industry protocols and safety measurements to take in order to safely dispose of the excess ethanol. They are highly toxic and meant to be used in industrial applications with heavy duty respirators, protective eyewear and hazmat clothing. For those that are not familiar with SLA printers, one of the steps in finishing a model is to clean it in isopropyl alcohol (IPA).

If disposing a container that housed resin, pour in some isopropyl alcohol and swish it around in the container to clean off all the resin in the container's walls. While not encouraged due to potential cross-contamination, you can get a very fine mesh screen (like you would use for cooking, and specifically polypropylene or stainless steel so it doesn’t react to the resin) and pour the vat back into the bottle to remove any bits of cured resin or failed prints. PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. Removing the vat, pouring in the resin, and reinserting the vat is safer just in case you spill any it doesn’t end up in the internals of the printer and coats all the boards in a runny, sticky mess of goo. Used frequently as a solvent, denatured alcohol is also helpful in household cleaning because its grease-cutting properties surpass ordinary soaps and detergents.

Contact your area waste disposal service, such as the city dump, and learn where and when hazardous waste materials may be brought for disposal. When you are about to dispose of the liquid 3D Printer resin, you are required to abide by the standard environmental regulations. Nylon and nylon composites perform exceptionally well in a variety of uses, it just takes a gentler touch to print it successfully. These resins need to be handled with care from opening to disposal. Cured epoxy resin (completely solidified) may be disposed of as non-hazardous waste in most municipalities. You will also need alcohol to clean the vat and the building platform. If you set it out in a jar the sun it will harden and settle and then let the alchohol evaporate if your done with it. Once the resin hardens it's pretty inert and you can dispose of it normally Make sure you have the proper Personal Protective Equipment  (PPE) whenever you are working with your SLA 3D printer. Do not pour liquid or partially cured resin into drains or dispose of it with household waste. Any paper towels or supplies that have come into contact with the resin should also be exposed to light and disposed of in the same way.
