What is Your Honest Idea About Resin 3D Printing?

One needs to be aware that resin 3D printing is not very specific to a certain area of additive manufacturing, but it is an umbrella term used for this kind of manufacturing technology. This method of manufacturing, 3D printing service, has something to do with curing liquid photopolymers in a layer-by-layer fashion so they can be custom made to a certain solid object.  

Although resin printing is not the official name or formal title for it, because these printing machines work a great deal with various resin materials, it’s become a convenient and apt way to describe or refer to them all. Alternatively, there are times that you will encounter instead of polymerization printing or stereolithography. In that case, know they are the same banana. technology

Defining Resin Printing in 3D

This type of manufacturing method utilizes the principle behind photopolymerization in creating/objectifying a particular digital design. 

Resin printing in a 3-dimension setup can only work under the conformity to a code.  This has something to do with the use of a computer system and software that will take charge of processing an uploaded digital model and then translates it to a code system for 3D printing. 

With regard to the materials used in this type of additive manufacturing technique, they utilize daylight or UV resins, otherwise known as photopolymers. They are normally stored inside a resin tank or vat.  

Photopolymerization is a qualified chemical reaction that happens to a liquid material changing its inherent properties after being subjected to wave light. Such light may include laser or ultraviolet, to name a few. These photopolymers are light-activated resins. When it comes to additive manufacturing 3-dimensional printing, we just simply refer to them as resins.  

We have a handful of different types of polymerization outcomes as well as reactions, but for 3-dimensional printing purposes, we would simply call it “solidifying”. Subjecting them under a proper wave light, liquid resins of this type tend to solidify in no time.  

How Does Resin Printers Create or Form an Object? 

Depending on how you position the components inside your printing machine as well as how your build platform would be dropped down or lifted, it is normal for 3D resin printers to form an object in an upside-down fashion. 

The upside-down orientation of printing is an unusual fashion in desktop system printing since they are far much easier to operate and fabricate that way sans running the risk of putting quality in compromise. 

If there is a downside to upside-down resin printing, it would have something to do with its supporting structures and print adhesion, keeping a part or component from falling apart or down due to the earth’s gravitational pull.  

Required Post-Processing Steps in Resin 3D Printing

Putting 3-dimensional printing alongside other popular or sought after methods of printing, this kind of approach will always necessitate a post-processing work. If you have a freshly 3D printed object make sure to observe the following points.  

Washing 

This is a crucial part of the post-processing work since it aims to take away any uncured resin, there would certainly be figments or leftovers from that particular printing work. To do so, you need to immerse your completed 3D prints into water, alcohol, at least allow to dry out on a few sheets of paper towels.  

UV-Curing

This part necessitates you to expose your completed prints to sunlight. Alternatively, you can also take good advantage of a portable UV-lamp. Do this part of the post-processing work, strengthen up your complete 3D printed object, and solidify even further.  

Removal of Support Mechanism

Whatever support structure you need to have on your 3D printed project, you will take them off in this part of the post-processing work. Resin printing requires a handful of the tree-like support structure which aims to hold the object in place. The build plate used in the process will help in keeping your printed object from falling apart. 

Usually, it takes no time to remove support structures, however, the process can be tedious and very time consuming also since it requires you to take great caution and care. Otherwise, you run the risk of cutting off too much from the volume of your 3D printed work.
