How To Make Stereolithography 3D Printing Models More Perfect
Want to make your SLA 3D printing models better? We've got some tips for you!
Friends who have played with stereolithography 3D printing should know that the just-printed model must go through the steps of removing the model, removing the support, cleaning and curing, otherwise it is not a real finished product. In this issue, I will show you how to complete these steps.
It should be noted that it is best to wear gloves when handling models. One is to avoid long-term direct contact between resin and skin, and the other is to avoid resin, which also has a certain protective effect on the model. Also, immediately after the operation, wash your hands with hand sanitizer. Now let’s officially start to introduce the processing process.
1. Removal of the model
Demoulding requires a certain skill and cannot be pryed open. If hard resin is used, it is easy to pry open the bottom raft, and even the support is broken and the model surface is damaged. After removing the model, wait patiently, run the shovel around the raft until you find the tangent point, and then slowly separate the model from the print platform.
2. Soak in alcohol
Put the removed model in alcohol to remove the residual liquid resin on the surface of the model.
3. Removal of supports
After soaking the wine, it is easy to remove the stand. Areas that cannot be removed or are not prone to spillage require post-processing.
Use high pressure flushing to remove ethanol and resin from the sample, and dry the sample. The company has its own large-scale 3D printing special printing equipment, fully equipped. Often comes with a cleaner to clean. Utilize the vacuolar action, acceleration and straight air flow in the liquid to directly or indirectly act on the liquid and dirt to disperse, emulsify and peel off the dirt layer to achieve the purpose of cleaning. If this step is handled by a professional machine, it will be much more convenient and trouble-free. For example, our company’s ultrasonic cleaner can easily and quickly clean the model.
The material properties of the model that has just been printed have not yet reached an ideal strength, and it needs to be exposed to sunlight for a long time to make the surface of the model harder. Many users have complained about this step, but this is also a link that cannot be avoided. However, now that there is a curing box, the curing work can also become very simple, as long as the curing function of our CB-300 curing box is turned on, the curing can be completed in a few minutes (if you want the model to become more rigid, you can put the time longer).
The purpose of grinding the model is to remove the hard-to-remove support and seal surfaces, make them smooth, and color them until the entire model making process is basically complete.
