ChituSystems Conjure Rigid Resin 1

REVIEW – I’m pretty new to resin 3D printing, but I have printed enough items to know that standard 3D resin can be very brittle. Chitu Systems contacted me and asked if I would review their Conjure Rigid Resin, so does it live up to really being rigid? Read on to find out.

What is it?

Conjure Rigid is a resin for 3D printing with engineering-like features for functional parts.

Design and features

Unlike most people who resin print models of characters, I print mostly functional parts. Brackets, mounts, and other objects you might consider tools or products.

I found that standard 3D resin was certainly not strong enough for my uses. It is typically brittle, especially when dropped on a hard floor.

I’ve been searching for a stronger resin, and the Conjure Rigid Resin is my first endeavor with”engineering” grade resin. I had purchased some of this resin with my own money before this review, but I was having issues with my printer and burned through most of it before I realized it was a software problem.

The Conjure Rigid Resin comes very well packaged in an air bubble-protected sleeve. The lid is very well sealed. Other resins sometimes have problems with leaking, but not so with Conjure!

Very nice lids that won’t leak

The Resin is advertised as having “long-term environmental stability, strength, elongation at break balance, excellent surface finish, and durability with impact resistance like ABS materials.” A low shrinkage rate of 0.2% to %0.7%, 90D hardness, and 37% elongation at break make the prints non-brittle and more durable.

Chitu Systems Conjure Rigid is compatible with most LCD printers using 385-405nm UV light, which is most of them. The material can also be tapped, milled, and turned. Although it is not advertised as being drillable, I did try a 1/8″ bit and a 1/4″ drill bit. It did not go well in a 1/4″ thick resin bar.

Although not designed to be drilled, I thought it might be nice to show what happens if you try.

My son designed a hub cap for his Datsun 280Z, and we printed it in regular Anycubix EC Resin. The next day he dropped it on concrete, and it broke. So I decided to see what the Conjure Rigid would do when dropped on concrete.

The cap survived with just a few dings, as just about any plastic would after hitting concrete.

I printed several test bars to test the strength of the Chitu Systems Conjure Rigid against the Anycubic EC Resin, which is a typical resin. The Conjure Rigid outperformed the standard resin by leaps and bounds. The Conjure Rigid was also less likely to break suddenly like the standard resin.

I also printed a functional belt clip, which standard resin is unsuitable for. It performs very well, bending to almost 90 degrees.

What I like

  • Prints Well
  • Very strong and flexible

What I’d change

  • Nothing I can think of

Final thoughts

The Chitu Systems Conjure Rigid resin printed well and performed well in my toughness tests. It does have quite a bit of flexibility when printing thinner parts, but overall it’s much better than a standard resin.

  2. Hi Mike,

    I appreciate this review as someone who also uses resin for functional parts. Do you know if the odor is particularly bad? I’ve heard many engineering grade resins off-gas some nasty smells during the printing process.
    I’ve been using SirayaTech Blu for my purposes, it works, the smell is not too bad but I wouldn’t want to hang around it for long.

    1. I haven’t printed with very many different resins, but it has less odor than some that I have tried. The Conjure Rigid has less smell than the Conjure Tough. I recently printed with some SirayaTech Tenacious, and the smell was about the same as that.
