Quite recently, we started selling Monocure3D Rapid resins. We have tested the resin and are ready to share our impressions and results.
A few words about the manufacturer
Monocure3D is a manufacturing company based in Sydney. Has 30 years of experience in the development and manufacture of UV curing products primarily for offset and 3D printing. Despite the fact that in Russia this brand is not so widespread, Monocure3D has a large army of fans around the world.
- The shrinkage declared by the manufacturer is very small, approximately 0.5%.
- The hardness of the already “dosed-up” resin is 70D Shore. In terms of hardness, it resembles Wanhao or Fun To Do Industrial resin.
- Illumination wavelength range from 225 to 420 nm.
- Sufficiently rich color palette. The resin is available in black, gray, blue, red and white. There is also a transparent resin.
For the tests, we took a blue Monocure3D Rapid resin .
The resin turned out to be translucent with a beautiful deep blue color.
Monocure3D practically does not smell, and this is a very big plus. Many resins we used earlier had a rather pronounced odor, and it was not entirely comfortable to use them in a small room. With Monocure3D, you can work with closed windows, periodically airing the room, which is very pleasant in our harsh climate =)
Let’s move on to the most interesting thing – the actual time of exposure of the resin. Monocure3D Rapid is marketed as a very fast exposure resin, in the official Facebook groups of Monocure3D and Wanhao you can see a huge number of examples of printed models from Wanhao D7 users with completely different exposure rates – from 2 to 8 seconds per layer.
So, what happened to us …
On Wanhao D7 we started with 4 seconds. Flat models turned out fine, but when printing volumetric models with supports, some of them did not print.
When the exposure time was increased to 6 seconds, everything began to be printed perfectly)
Layer 50 microns.
On FF Hunter, we started at 1 second. This was not enough either. I had to add 0.5 sec.
1.5 seconds per layer turned out to be the best exposure time for Hunter. There were no problems with support, the quality of the models did not arise)
Layer 50 microns. Rings, earrings, pendant and bracelet.
Immediately after printing, the resin remains slightly flexible. This has proven to be a big advantage when removing supports. It is very quick and convenient to cut the supports with a sharp scalpel. After additional illumination under a UV lamp, the models became quite tough, but, it is important to note, NOT fragile.
Layer 50 microns. Jon Snow who knows nothing =)
Few rings. Layer 50 microns.
A small bracelet.
Even before we got our hands on Monocure3D resins, we got acquainted in detail with many custom resin cases that are on the Internet. And based on user reviews, we can conclude that the resin has an almost impeccable reputation. A priori, we had no doubts about the quality of the resin, but we really wanted to check the exposure rate on our own experience, and confirm or deny the established reputation.
Of course, we did not achieve 2 seconds of exposure per layer when printing on D7, but the result is 4 sec / layer for flat models and 6 sec / layer for volume models, also pleases =) If you compare with other resins, the speed is higher, maybe not in times, but still it is felt. With Flashforge Hunter, the situation is identical – not every polymer can boast of 1.5 sec / layer.
From our own experience we were convinced that Monocure3D resins are really high-quality and reliable resin, probably one of the most problematic among those that we have used. The surface of the products is smooth, beautiful, with a pleasant texture. Monocure3D makes excellent models that require high precision and detail.
