From game pieces to gadgets, there are lots of reasons to purchase a resin printer.
These days, one of the most popular is the Elegoo Mars or its recent successor, the Elegoo Mars Pro, which has just started shipping to customers at the time of writing. These machines use an LCD screen under the resin vat to send ultraviolet rays, solidifying the object from the surrounding liquid.
Resin printers have access to a variety of different types of resin out of the box, unlike FDM printing, which can require upgrades for special filaments. Below is a list of resins that have been verified to work with the Elegoo Mars, plus their uses and where to purchase them.
Note that this isn’t a review of resins, simply a list of different types of available resins, with some brand recommendations that you may want to try. We’ve also included some tips on how to find more resin options at the end of the article.
Marketed under many different names, ABS-like “tough resins” boast a high level of impact resistance. Acrylonitrile butadiene styrene (ABS) is a plastic commonly used in toy manufacturing, personal protective equipment such as hard hats and helmets, and other uses where the object will be put through stress.
Brand: iFun is one of the few resin makers that list Elegoo by name as being compatible with their product.
Pricing: ~$60 (€53) for 1 kg
Colors available: White, grey, blue, purple, green, and more
A major advantage of 3D printing is its ease and speed in prototyping, and castable resin is a prime example.
For example, jewelers can print a model, use it to form a cement mold, and burn away the resin in a furnace, allowing the liquid metal to be poured into its place. A single 3D printed ring or brooch in this castable resin can form the mold for dozens in gold, silver, or other metals.
Brand: One of the best-known castable resins is Powercast’s Burn.
Pricing: ~$100 (€90) for 250 grams or $300 (€270) for 1 kg
Colors available: Limited, though not relevant for the final product
One of the fastest-growing areas of commercial 3D printing is happening in your mouth. In the last decade, dental professionals have increasingly used resin printing to create everything from dental models to custom teeth-whitener trays. As with anything you want to put in your body, consult a professional before trying to make your own dentures.
Brand: Asiga has a range of specialty dental-applicable resins.
Pricing: ~$300 (€270) for 1 kg
Colors available: Depends on the usage; off-white for dentures, clear for trays, light pink for molds
Sometimes, you need to be a little flexible. FDM printers use thermoplastic polyurethane (TPU), a rubber-like material found on drop-proof mobile phone cases. TPU-like resin, often going under the line name “Flex”, can be similarly used for items where high elasticity and vibration absorption is needed, such as race car vehicle wheels.
Brand: Druckwege in Germany has developed a flexible resin specifically for UV printers.
Pricing: ~$90 (€80) for 500 grams
Colors available: Several (though Druckwedge only produces in black)
Whether you’re making safety reflectors for your night-time runs or spooky figurines for your tabletop roleplaying game, glow-in-the-dark effects are cool. FDM printers often have a hard time dealing with the additives to make the filament glow, wrecking tubing and hot ends. Lucky for you, your Elegoo Mars (and resin printers in general) can create armies of ghosts, ghouls, and goblins with no problems.
Brand: Liqcreate’s Hazard Glow works across multiple types of resin printers, including, of course, the Elegoo Mars
Pricing: ~$55 (€50) for 250 grams
Colors available: Limited (as it has to glow in the dark)
The attributes that make 3D printing a superior method of testing ideas – small batch creation, no supply lines, and little extra infrastructure needed – make it a poor choice for mass manufacturing. High-temperature resins seek to bridge the gap, as they withstand temperatures suitable for use in traditional manufacturing methods, such as injection molds.
Brand: Sparkmaker’s LCD-H boasts the ability to withstand temperatures up to 320 °C, making it usable for most consumer-grade plastics, and even some metals.
Pricing: ~$90 (€80) for 500 grams
Colors available: Grey, clear, white, beige, light yellow, and black
The Elegoo Mars can’t print with metal, nor can any other LCD resin printer. But that doesn’t mean your printed objects can’t look like they’re made of metal. Metallic resins mimic the appearance of various types of metals, including gold, silver, brass, steel, and iron.
Brand: Dragon Resin’s Metalshine is a small line of metallic resins that includes dark grey metal, brass, and darkened brass.
Pricing: ~$33 (€30) for 500 grams or $60 (€53) for 1 kg
Colors available: Limited (just three options)
Using soybeans and similar plants as the setting agents for the resin, rather than traditional sources, makes this goop environmentally friendly, biodegradable, and best of all, non-toxic while printing. You’ll want to try out new methods of printing and experimenting with supports with this type of resin. If it fails, it can go into the compost rather than the landfill.
Brand: At the time of writing, Anycubic is the only commercially-available source for this resin.
Pricing: ~$50 (€44) for 500 ml or $70 (€62) for 1 L
Colors available: White, orange, violet, grey, pink, green, blue, black, clear, and more
Resin that cures quickly has multiple benefits beyond a quick turnaround. The shortened time frame prevents shrinking and deformation of parts still soft from the bath. Use this resin if precision is needed, such as when making tools or components.
Brand: Sainsmart’s Rapid resin is a great choice.
Pricing: ~$70 (€62) for 1 L
Colors available: White, orange, grey, pink, green, black, clear, and more
True transparency is tricky with resin. Most transparent resins that claim to stay clear are for other kinds of printers, since UV light is integral to both the curing and yellowing processes.
Brand: ApplyLabWork’s MLSA Modeling Clear resin claims it has “minimum” degradation and, with the proper post-processing, can become clear.
Pricing: ~$82 (€74) for 1 L
Colors available: Limited (clear only)
White is one of the most popular colors to print with, yet it’s one of the hardest for resin makers to get right. Often the milk-white of the resin will turn into old ivory or worse: an aged yellow color familiar to anyone who had video game systems in the early 1990s.
Brand: Fun to Do’s Snow White is a good one, but always check the reviews before you purchase.
Pricing: ~$70 (€62)
Colors available: Limited (white only)
Resin printing is messy, as you’re dealing with chemicals that irritate the skin, eyes, and sinuses, smell awful, and can be dangerous. This type of resin seeks to address at least some of that by post-processing in water, rather than 90% rubbing alcohol or methylated spirits.
Brand: Elegoo has a range of water-washable resins in a variety of colors
Pricing: ~$35 (€31)
Colors available: White, yellow, grey, red, green, blue, beige, black, and more
There’s an almost endless variety of resins to experiment with and explore, but not all of them work with the Elegoo Mars or Mars Pro printers.
Here are a few tips to help you find more options:
Keep your eyes open and don’t be afraid to try something new!
