The 3D resin printer market is in rapid evolution, after the release of the Creality LD-002R at the beginning of the year to compete with Anycubic Photon and Elegoo Mars, Creality has just released a brand new model: the Creality LD-002H.
What is the difference between LD-002R and LD-002H?
The major evolution of this 2H version is above all the use of a new type of Monochrome LCD screen, which allows it to print up to 4 times faster by reducing the exposure time. Indeed, this type of screen being thinner, and allowing more UV light to pass through, allows the resin to cure in only 2sec (on average) compared to 8-10sec for a conventional RGB LCD screen.
Another improvement to the LD-002H is that it uses a larger 6-inch screen, which allows a larger printing area of 130mm*82mm (compared to 119mm*65mm for the 2R version), while the printing height remains unchanged at 160mm.
Finally, in terms of appearance, the machines look very similar, the machine frame is globally the same, seen from the outside you will only notice the colour of the cover which has changed, red for the new LD-002H, and orange for the LD-002R.
This LD-002H is always equipped with a carbon filter to reduce the diffusion of resin odours, a graduated VAT, a maintenance door on the side for easier screen replacement, and the power button on the front.
When unpacking the machine, you can see that the machine is fully assembled and ready for use in a few minutes. Some accessories are supplied, such as a spatula, a USB key or spare FEPs.
First impression with the LD-002H
On the USB key you can find 2 test files to be printed, an eiffel tower and a half sphere.
Before starting your first print, you will have to level of the plate, this procedure is relatively well explained in the instructions (in English). You will have to loosen the plate, then make an auto-home, either with the VAT without resin, or with the help of a sheet of paper, then tighten your plate to keep this thickness of sheet/FEP between your plate and your screen, finally record this value with the option Z=0.
Once this procedure has been completed, you are ready to start your first printing! I always recommend that you run a model present on the USB key to check that the printer is working properly.
Here is my very first print, with an exposure time of 2sec per layer. The rendering is really very clean.
For the second printing, I will create my own file, using the Chitubox software, which already offers a default profile for the Creality LD-002H, you will need version 1.6.5.
However, by default the plate movements are not very fast (50mm), so this will slow down your prints, I have replaced the values lifting speed and base lifting speed at 100mm.
Here are the few prints I was able to make with the LD-002H, with an exposure time of 2sec per coat, and Eryone waterwashable resin.
Last print, this time with an exposure time of 1.5sec with IFun High clear resin.
Post-processing of resin prints
3D resin printing is great, with much better print quality and detail than a filament FDM printer, but you will need to spend some time cleaning your parts, either with IPA alcohol, or with water if you are using waterwashable resin.
After this cleaning phase, you will also need to UV cure your model, to harden it further, you can either use a homemade UV lamp, or a Wash&Cure solution (budget between 120-150€) all in one, or use a curing box (budget 50€), for the prints made with this LD-002H, I used the Curing Box SL1 from Sovol, which is sold on Amazon for about 50€, it is very light and easy to use (I place it on top of the printer to save space).
I was lucky enough to be able to test this new Creality LD-002H printer among the first, I had already been pleasantly surprised by the old 2R version, and this is also the case for this 2H.
Its price remains very attractive, $249 for its launch via the official creality store, is cheaper than equivalent competitor models. You can always opt for the 2R model if speed is not an important criterion (sold at $199), the print quality between these 2 machines will be similar.
