What does your company need to get ahead of the competition? Perhaps we have the answer.
Resin 3D printers are said to be the new best way of creating three dimensional objects. Many companies are slowly introducing this type of 3D printer and they’re loving the results.
What is it about 3D printers that make everyone in multiple industries want them as part of their processes?
You can learn why they’re becoming so popular by reading below. Will you also invest in a resin 3D printer soon?
What Are Resin 3D Printers?
Do you know what a 3D printer is? It’s a device that is computer aided to create 3D objects. It uses different types of filaments to create the design, by layering them on top of each other.
3D printing brings people’s visions to reality in an affordable way because they significantly reduce the cost of production. For companies, this is probably the biggest reason why they’re popular.
3D printers are all similar, but unique features make some of them perfect for certain applications. So, let’s look at resin 3D printers.
Resin 3D printers use a different type of technology for their creations. It’s called stereolithography and it’s one of the most popular techniques for producing high quality 3D prints.
In essence the stereolithography brings an astonishing finish that no other type of 3D printer can produce. It’s the high quality look many companies seek especially when they need resin 3D printers for full production and not only prototypes.
What Is the Process of Stereolithography?
The process of stereolithography, which is found in many 3D printers, works with UV lasers. The printing process first starts where the roller spreads out a thin layer of resin. This layer spreads out over the entire platform for it to have a consistent thickness. It’s best if the resin you use is UV sensitive.
The UV laser that’s attached to the printer “draws” the desired object’s outline onto the resin layer. All the parts that the UV laser touches turn solid. The rest will remain liquid.
The model requirements will lower by a fraction and the roller will spread out a new layer. The UV laser prints over the new layer and solidifies parts of the resin. These steps are repeated until the final model is completed.
Once completed, the print is raised out of the resin tank. All the excess liquid goes back into the hold ready to be used again for other prints.
You then remove the print and manually finish the look by painting it to enhance the look.
The Different Types of Resin
There are four stereolithography-based resins that are ideal for the different objects that you want to create.
They all have two characteristics in common:
- They all result in smooth surfaces
- They are ideal for post process
Mammoth resin is constructed from the liquid type. It also hardens by the laser and it’s mostly suitable for large print jobs. It’s effortless to create shapes up to 2100×700×800mm.
This type of resin is most suitable for printing large jobs with limited functionality. It’s great to create protective body parts for other objects.
Characteristics of the mammoth resin include:
- The visibility of layers depends on the shape of the object. Curved ones tend to show more layers
- Small dots can occur if the 3D printing support structure was touching the model while in process. This can easily be removed with sandpaper
- Discoloration can occur if you don’t varnish or paint the model
This type can also be used on printers specifically made for the mammoth type. The final object will have a transparent look to it. The color of this resin can change.
Transparent resin is also constructed of liquid resin and hardens by laser. The freedom of design is limited because of the support structure needed when the object is created.
This is more suitable for objects that need to be transparent with a smooth finish and don’t have moving parts, such as:
- Cellphone covers
Characteristics of transparent resin include:
- The exact transparency varies between translucent and crystal clear
- The greater the thickness of the resin the darker the color of the final product
- Imperfections and minor scratches will be noticed
- It’s wise to add varnish to the final object to slow down the discoloration process
Gray resin has one of the greatest surface qualities and a high level of detail. Again, it’s made from liquid resin and hardens by UV laser.
It’s ideal for creating small to medium sized objects. The object measurements can be within 250×250×235mm.
Because of its high detail gray resin can be used to create objects similar to model trains and figurines.
The manufacturing characteristics are similar to that of mammoth resin:
- Curved objects have a higher layer visibility
- The support structure used during the manufacturing can leave small dots on its sides. Sandpaper can remove these; however, there is a risk that it can leave scratches on the surface
- The UV light causes the resin to discolor quicker. To slow down the process it’s best to paint over it with a varnish
The standard resin is ideal for those who have lower budgets yet still want effective results. It has all the other manufacturing characteristics found in the other three types.
The resin is a yellow to white color. It’s a great option if you want to create multiple prototypes before deciding on the final color finish.
The standard resin is also an ideal material to create small- to medium-sized objects with measurements of 250×250×235mm. With standard resin you can create:
- Toy models
- Animal replicas
It leaves you with a simple yet beautiful design and finish.
Clearly, if you want show-stopper pieces, then resin 3D printers are what you need. The quality of their products is unmatched, so you can impress with them wherever you use them. Give your company the competitive edge it needs.
