If you\u2019re getting more comfortable with the process of 3D printing, you may be questioning pieces of the process your manual told you are mandatory. Some hacks will help you cut costs, while others will help you craft your projects more efficiently. Is washing and curing something you can skip?\n\n\n\nYou should always wash and cure your resin prints because the resin is a toxic material. When your resin prints come out of the printer, they\u2019re still covered in uncured resin. You\u2019ll need to cure the prints to guarantee high quality.\n\n\n\nResin, when uncured, can be harmful. Below, I\u2019ll discuss in detail the importance of washing your resin prints, techniques for cleaning them, and what\u2019ll happen if you don\u2019t wash them correctly.\n\n\n\n\n\n\n\nDo You Need To Wash and Cure Resin Prints?\n\n\n\nCutting time or labor costs is a common desire when you start 3D printing.\n\n\n\n3D printing is a pretty expensive hobby, and if you\u2019re using your 3D printer to make products you\u2019re selling, you may want to speed up the process. You may have read articles telling you where you can cut costs, what temperatures may speed up the process without harming your product, and so on. But what about curing your resin? Is that something you can skip and save some money on?\n\n\n\nYou need to wash and cure your resin prints. Resin is a toxic material that\u2019s not recommended to touch skin and can make you sick long term. Not to mention, skipping this step in the process lowers the quality of your product and makes it challenging to paint on.\n\n\n\nLet\u2019s discuss strategies for curing your resin prints.\n\n\n\nWhat To Buy To Cure Resin Prints\n\n\n\nTo cure your resin prints, you\u2019ll need a few things in your toolbox. Some of these items are things you may already have around the house, while others you may need to go out of your way to purchase. As discussed above, curing resin prints is necessary to avoid dangerous side effects, so it will definitely be worth it.\n\n\n\nTypically, when using resin, it\u2019s a good idea to invest in the following:\n\n\n\nA pair of quality gloves to act as a barrier between the resin and your skin.A pair of safety goggles just in case something splashes.\n\n\n\nHow To Wash and Cure Resin Prints\n\n\n\nWashing and curing your resin prints go hand in hand, but they\u2019re two completely separate steps.\n\n\n\nWashing your resin prints is the process of getting all the sticky residue off of your resin model, usually done with some form of alcohol while curing your resin prints is the process of letting them dry off in UV light to finish forming.\n\n\n\nSome printer companies or resin supplies will offer products that make the curing process easier. If you didn\u2019t purchase a wash and cure station with your printer or resin, you can usually go back to the manufacturer\u2019s website and grab one. Or, if you\u2019re trying to cut costs, you can check out all the options and select whichever one fits your budget. Just be aware that it may take some experimenting to get the formula down.\n\n\n\nRegardless of your choice, you\u2019ll begin with a rinse of your resin. For the wash, if you do choose to do it without a kit, you can check out one of the following:\n\n\n\nIsopropyl alcohol or IPAtripropylene glycol monomethyl ether or TPM (non-flammable)Dipropylene glycol monomethyl ether or DPM (non-flammable\n\n\n\nDepending on the method you use, you\u2019ll usually be pouring this chemical into a cup or tub that is big enough to fit your product and not overflow. As always, follow best practices when using chemicals.\n\n\n\nTo wash your resin print, you can use a few different methods.\n\n\n\n\n\n\n\nSoak and Rinse\n\n\n\nHere\u2019s are the steps to wash and cure resin prints by soaking and rinsing:\n\n\n\nFill a cup or a tub with your choice of alcohol. Be sure there\u2019s enough to cover the top of your model, but not so much that the water will get displaced when you put your model in.Then, you\u2019ll submerge your model into this tub. Use the alcohol to rinse your model, swirl it in the alcohol, or do what you can to make sure each part is touched.This may need to happen multiple times to ensure the resin comes off. You can use a brush to help make sure it gets in all the nooks and crannies.\n\n\n\nUltrasonic Bath\n\n\n\nUltrasonic baths are a more expensive option, but they\u2019ll put your heart at ease if you worry about toxic exposures. This may come especially in handy if you want to sell your products in good conscience. An ultrasonic bath uses one of the alcohols listed above. All you do is submerge your product and let it sit for a few minutes.\n\n\n\nCuring Resin Prints With a UV Light\n\n\n\nNext, you\u2019ll need to cure your resin print.\n\n\n\nThis is typically done with UV light. Just like some printers and resin products come with cleaning supplies, some will also come with UV lights custom-made for their resin product.\n\n\n\nIf you\u2019re unable to purchase your brand UV light, don\u2019t worry. You can just as easily buy a UV light online for curing resin or just a normal UV light. Some nail products require UV light to work, so it\u2019s relatively inexpensive to get a UV nail light online or even a UV light used for decoration.\n\n\n\nIf you buy a UV light, you can create your curing station by putting tinfoil in a box or tub to reflect the UV. You can then place your project in the middle.\n\n\n\nIf none of this is within your budget, the sun has the OG UV you need to cure your resin. You can just place the product outside (away from any animals or children) and let the sun do your curing.\n\n\n\n\n\n\n\nWhat Happens if You Don\u2019t Cure Resin?\n\n\n\nUncured resin can put you at risk for health issues and toxic exposure. It can also make your product sticky to the touch and difficult to paint. Curing your resin print makes the product quality higher and protects you from the risk of toxic exposure.\n\n\n\nYou should always wash and cure your resin products.\n\n\n\nWhat To Do if You Come in Contact With Uncured Resin\n\n\n\nIf you come into contact with uncured resin while not wearing your gloves, you should wash your hands with soap and water immediately. Though it may make sense to use hot water (maybe with the train of thought that it\u2019ll help melt it off), you\u2019ll want to use warm water, so your pores don\u2019t further open and absorb the resin.\n\n\n\nPrinting Materials Alternative to Resin\n\n\n\nIf you don\u2019t think resin is worth the risk, there are alternatives to printing with resin. You\u2019ll likely need to invest in a new 3D printer that takes other materials. Some popular materials for 3D printing are:\n\n\n\nPoly lactic acid (PLA) filament, a plasticAcrylonitrile butadiene styrene (ABS), a plasticPolycarbonate (PC), a plasticAlumide, a powderPolyamide (Nylon), a powder\n\n\n\nRelated Articles\n\n\n\nCan You Put UV Resin Over Epoxy Resin?
