Resin 3D printers are an immensely powerful tool in the hands of a maker and they have never been more accessible. So, welcome to a rundown on this technology. We're also going to give an explanation of the tools you're going to be provided with and show you exactly how to home and level the print build platform.

By the end of this video, you're going to be ready to pour this liquid resin into the tank of your 3D printer and start a print. These machines all work with photopolymers, which in this case are UV curing resins. These resins cure into a hard plastic when exposed to UV light. In the case of these Creality 3D printers, it's done through a UV projector. This curing is going to be done layer by layer with each layer stacking on top of each other to create a complete 3D model.

Now, I've been printing with the early design, the Creality LD00R resin printer for a while now. So, allow me to make clear the differences and similarities between the older model and the newer LD00H. The major differences between these two printers are the larger build area of the LD00H printer, which means the horizontal area has increased by approximately a third from the previous model. The newer model also uses a 2K monochrome display instead of the RGB LCD display for the masking screen. Monochrome screens have fewer layers, thus allowing more UV light through, and this drastically reduces curing time from 12 seconds a layer down to around two seconds per layer. Your overall print times are gonna decrease, particularly when you consider a single print can have thousands of layers.

Here on the table is most of the tools that come in the box. Starting off is the sharpened metal spatula used for removing a 3D print from the build platform.By sliding it underneath the model.

Next, we have the plastic spatula, very useful to help clean the FEP sheet and remove unwanted cured resin if it's floating around in the tank.

Next is the soft bristle brush. This is good to gently clean the parts and models in combination with the IPA.

You're also gonna get four strain filters. Good practice is to keep the uncured resin inside sealed containers. If left out in the air for too long, it can affect the print result. These strain filters make it easy to pour the resin out of the tank back into a container whilst not letting the cured resin contaminate the good resin.

Beneath the resin tank at the base of the machine is a UV projector that projects the images up to the bottom of the tank to cure each layer of resin. Before the light can get through to that resin tank, there is an LCD screen that it must travel through. This screen produces a mask for each specific layer so that the UV light will only cure the necessary sections. Slicing software creates these layers that the LCD screen follows so it can produce each layer precisely. And Creality 3D printers have many different slicing softwares that can work with them.

You're also gonna get a USB stick, and this is what we're gonna use to bring the files from your computer into your printer.

You're gonna get three Allen keys, and these three Allen keys you can effectively use to pull apart the entire resin printer. The most important one at this stage is the smallest size, which we're gonna use to correctly level and home the build platform. This is what we're gonna be printing directly onto. It has an exposed aluminum surface that has been treated with a light scuff marks, which is gonna help improve adhesion.We are unboxing the printer, Creality is a little bit sneaky here and basically disguises the build platform inside the foam packaging. So make sure not to throw this out until you get that platform out.

The resin tank. This tank, also referred to as a vat, comes with a FEP sheet installed already on the bottom and has clear resin level markers on the side of the tank. Now a FEP sheet is a transparent sheet of nonstick plastic, which is found at the base of the tank, which allows each cured printed layer to peel off after curing. This process happens many hundreds of times to create a model.

Also in the box is a spare FEP sheet and this sits at the bottom of the tank with instructions on the back of this piece of cardboard on how to install it. Now, a quick note in safety, the Creality LD00R 3D printer back there came with gloves and masks, which is great, but the LD00H did not. Make sure you have safety equipment on hand as it's gonna be needed. The goal is to prevent resin from making contact with your skin and stopping any fumes from getting inside you. The parts you produce from it are not suitable for food or children toy applications. Thus, gloves, eye protection, and masks are definitely needed when working with these printers.

You'll always wanna place the acrylic cover on top when it's printing and when it's just sitting there, not only to trap the fumes and allow them to be caught by the carbon filter, but also to protect the resin in the tank from curing by latent UV light.

The very first step for setting up any resin 3D printer is to level and hone the print platform. The goal here is to make sure the print platform is perfectly flat in relation to the surface of the LCD screen and has a zero point exactly.Where the top of the FEP sheet is. We're gonna remove the tank by unscrewing the two large thumbscrew knobs on either side of the tank. You can do this without lifting the print platform mount.

We're gonna plug in your machine and using the touchscreen, raise the print platform mount to about the halfway point. You can find this option by clicking on the tools button, then the manual button. Press the triangle symbols to move the mount.

Now we're gonna attach the print platform to the print platform mount. Unscrew the large thumbscrew, which is on the top of the mount and slide in the build platform. Then screw that thumbscrew finger tight.

We're gonna place a normal A4 sheet of paper over the screen where the tank was. What we're doing is emulating the height of the FEP sheet. Around the edges of the build platform are four Allen bolts, each in a slot hole. We're gonna unscrew them so that they are all loose with the Allen key supplied.

Having done this, we're gonna tap the home button represented with a house symbol on the touchscreen. This will bring down the build plate to the level of the LCD screen surface. With it resting on top of the A4 sheet, push down just lightly and evenly on top of the build platform. Whilst doing that, slowly tighten all the bolts bit by bit going around in a circle.

Now we can tell the build plate to go up and out of the way. You should also pull off the protective surface on top of the LCD screen. Reattach the tank, which already has the FEP installed from the factory. And with that, you've correctly homed your free printer.

In the next videos, we're gonna dive into the printing settings, provide exact post-processing procedures, and show off the best slicing software for resin 3D.Printing. I'm gonna provide you with all the information you need right at your fingertips so you can produce stunning printed models and functional components with this technology. So with that, jump into the next video or until next time, stay cozy.
