Best Resin for your SLA/DLP 3D Printer Windows Central 2019

When faced with multiple colors and multiple types, it's easy to get turned around when trying to choose the right 3D printing resin. We've used as many as possible to bring you some of the best you can buy.

Best Overall: eSUN General Purpose Resin

eSun general-purpose resin is, as the name implies, a general-purpose material for 3D printing using an SLA/DLP printer. It can be used to print cosmetic models — D&D miniatures look fantastic in it — or used to make more mechanical prints, like replacement parts or prototypes.

The general-purpose resin from eSun is perfect for those of us who want to try many different applications of printing, as opposed to drilling down into something specific. With it's high tolerance to heat variances and seemingly magical ability to bring out details even when it's overexposed, it gives you a chance to experiment without every print failing spectacularly.

Unless you have a particular use case for your resin — metal casting, for example — then the general purpose resin is an excellent choice for all your needs.

Pros:

  • Great price
  • Even coloring
  • Prints smoothly
  • Bottle is airtight

Cons:

  • Can be a little brittle
  • The edges can pale if over-cured

eSUN General Purpose Photopolymer Resin

Amazing prints

The eSun General purpose resin has made an almost perfect print every time we've used it. For 500ml, the price is excellent too.

Best Bulk Buy: AnyCubic UV sensitive resin 1 Liter

When I first got my Photon DLP 3D printer, it came with a 500ml bottle of AnyCubic resin, and I loved it straight away. The transparent, almost glass-like quality was mesmerizing, but the bottle was only 500ml, and I wasted a lot of it learning how to use the printer. AnyCubic sells its resins in one-liter bottles too though, so I snagged one to keep me going. If you have a little extra money, it pays to buy in bulk.

If you are going to buy in bulk though, make sure you have a cool, dry place to put all the bottles of resin and make sure they are away from kids and animals. Resin is dangerous and should be treated like bleach or other toxic chemicals.

Pros:

  • Low price for a lot of resin
  • Beautiful clarity
  • Easy to print with

Cons:

  • Can appear cloudy if you don't cure correctly

Best Bulk buy

AnyCubic UV sensitive resin 1 Litre

The more, the merrier!

Not only do AnyCubic make excellent 3D printers, they also make great resin. It's pricey, but worth it for the extra 500ml.

Best Budget resin

I've been using a lot of the ELEGOO resin recently to reduce my outlays. It's super cheap and gives a great overall model. Some of the details may be lost, but you can tune it pretty well to provide you with an overall good product. I particularly like the grey as it shows any issues in the print very clearly, allowing you to fix the print easily.

I would use the ELEGOO for those models you are thinking of post-processing — sanding and painting this resin works well — or if you are printing large models without too fine details.

Pros:

  • Great value for money
  • Consistently good quality
  • Great for post-processing

Cons:

  • Some definition can be lost
  • Very brittle

Best Budget resin

ELEGOO 3D Rapid Resin

Cheap and cheerful

Elegoo is the cheapest resin out there, and the quality is pretty good. Buy this if you plan to post-process your models.

Best for Toughness

There is a lot of reason to choose Siraya Tech (blue) as your resin of choice. Firstly the blue is gorgeous, it looks like tropical water on a clear day, but more importantly, it is tough. Resin can be extremely brittle once it is cured, making it unsuitable for anything other than model making.

As Chris Russell shows in this picture, you can even make parts for other 3D printers using the Siraya Tech tough resin, and they will look beautiful and be strong as heck.

The Siraya (blue) though, is extremely tough and can withstand impacts — even high falls and drops — much better than any resin I've used before it. This makes it useful for building cases and objects that are more useful than just pretty models to sit on a shelf.

Pros:

  • Impact-resistant
  • So pretty!
  • Good for tough jobs

Cons:

  • Expensive

Best for Toughness

Siraya Tech Tough (blue)

Extra tough

The biggest issue with resin printing is the fragility of the finished product. This resin is extra sturdy and droppable!

The Bottom line

I love the eSun brand. Its PLA and its resins are great at what they do, and they do it for a price that doesn't break the bank. The general purpose resin lets me try multiple different 3D printing techniques, and is very forgiving when I make mistakes.

If you are looking for an all-rounder, a filament that makes your life a little easier, then look no further, the eSUN General Purpose Resin is for you.

If you are looking to print as many prints as possible though, you may want to look at the Anycubic 1 liter options. They seem to offer the best deals on bulk buying, and if you are new to resin printing, you will need all the resin you can get!
