Resin 3D printing lets you print out 3D models of countless types so you can use them in professional applications. Alternatively, the technology is just used to express creativity. We are faced with one of the best options available on the market. An Elegoo resin 3D printer can easily help you create what you really want. However, this does not mean the process is that simple.
There are several really important things you have to know before embarking on your resin 3D printing journey. For instance, did you know there are several 3D resin printing technologies possible, like DLP, SLA, and LCD?
Make sure to learn all that you can before you buy your first resin 3D printer. Start with the really important things highlighted in the following paragraphs.
Finding High-Quality 3D Printing Files
3D printing files are absolutely necessary or you simply cannot start printing. Commonly, this file is referred to by the name STL file. You can find STL files in several ways.
Those who are really good at design can create their own STL design print files. This is possible with the use of software like CAD or Tinkercad. Obviously, there are also professional designers you can hire to design the STL files. This is one of the best options when you want really custom design work done for you.
If you do not have a budget, you can get STL files from free websites. But, the quality is not always the great. Alternatively, those interested in resin 3D printing with a limited budget can get paid STL files.
How To Choose Resin For Your 3D Printer
Resin is needed to print the 3D models you get. This is obvious. What is not so obvious is how to choose the right product. Liquid resin has a chemical structure that makes it harden if exposed to a source of UV light.
After the liquid is poured into the Elgoo printer’s resin vat, based on the technology the machine uses, UV light will make it hard, layer by layer.
Based on the needs you have, several good resin products are available on the market. For instance, one of the high quality ones is sold by Phrozen. The company offers several great products, including the Aqua-Gray 4K option. It is great for professional appliances, jewelry 3D prints, and 3D figurines.
Obviously, some other liquid resin products might be better for your project. Make sure to read as many reviews as you can so you choose something that is highly recommended for your printer and your project.
Take Advantage Of Slicer Software
3D files need to be sliced before they are saved so that you can be sure that the resin 3D printer will be able to read your file. STL files are sliced and then converted into really small layers. The resin printer will decode the information as the printing job is happening.
It is important to know that 3D print height is directly linked to how much time it takes to do the print job. The best slicer software utilized to slice the 3D files varies from one printer to the next but one of the best is CHITUBOX Slicer Software. You can also go for some premium software designed to help with specific tasks, like slicing for dental products.
Slicer software is also really important because it sets supports on the 3D models. This should be done before the STL files are sliced. These supports help you in the printing process. Also, the supports will help anchoring your 3D prints to the printer’s building plate.
Setting Up The 3D Resin Printer
After the printing file is chosen and you slice it, it is time to set up the actual 3D resin printer. Some steps are very important at this stage of the process.
If the unit uses LCD technology, it has to be tested. The 3D printer has to be set up and you have to calibrate the printer’s Z-axis. These steps have to be correctly performed since it guarantees that the print job is going to be perfect, based on the 3D models you are using.
3D Print Post-Processing
After printing the 3D model, you have to go through post-processing. This involves cleaning the model so you are making sure it is not going to crack. In addition, the process guarantees that the finishes of the 3D prints will be smoother and the model will last longer.
All the detergent, sanitizing alcohol, and water you use during the cleaning process should be properly disposed of. Sunlight exposure is highly recommended before you remove the cured resin located inside the liquid. Do this before disposal.
After the 3D model is printed, remove the supports. Then, use 2 basins with sanitizing alcohol. They are needed to wash the 3D prints. Do so until you do not see a reflective surface anymore. Air guns can be utilized for the purpose of drying out the 3D model. Alternatively, just set the model aside and wait for it to dry.
After the drying part is over, the 3D models have to be cured. This is done with the use of natural sunlight or UV light. Buy a high-quality curing lamp for this step of the process. Do not settle for low-quality units.
3D Resin Printer Maintenance
Every type of resin 3D printer needs specific maintenance routines to be carried out. For instance, with the LCD models, you have to take care of the PFA or FEP film used. These consumables have to be replaced from time to time. DO so when you notice that the film has bumps, scratches, or any other visible damage.
Regular maintenance is simply mandatory or you will not end up with the best possible print quality. Fortunately, every single good 3D resin printer comes with a manual you can use in order to check all the maintenance needed. If you do not have the manual, simply go online and look for the website of the manufacturer. They should be able to provide you a digital copy of the manual for your 3D resin printer.
