In the 3D printing industry, whenever I mention light-cured 3D printers, I always feel bright. In fact, this printer really deserves to shine at the moment, because it uses ultraviolet light or other light beams to cure liquid photosensitive resin. As for photosensitive resin, what's the matter? Literally, it is a photosensitive resin material, which will cure quickly after illumination. At a higher level, photosensitive resin is a mixture of photoinitiator, monomer polymer and prepolymer, which can be cured under the focus of ultraviolet light with a specific wavelength.
Solomon has a variety of consumables for you to choose from, such as high conductivity, toughness, hardness, high toughness, hand-dedicated, dental and jewelry casting 3D printing photosensitive resin consumables, with optional colors, suitable for desktop LCD/DLP 3D printers; It is suitable for 3D printing creation of assembly parts, molds, jewelry casting, animation, dentistry, sole medical models, etc. , color optional, affordable!
Photosensitive resin material? Generally used in SLA/DLP/LCD models, stereoscopic mask aligner is used in these printing technologies, and photosensitive resin is used as consumables. Articles printed with photosensitive resin materials have smooth surfaces and high molding quality, so many DLP models are positioned as jewelry-grade, and LCD is gradually approaching the pace of DLP, with higher and higher accuracy. LCD technology has been widely used in industrial manual work.
Characteristics of photosensitive resin
Photosensitive resin is generally in a liquefied state, and articles printed with this material generally have the characteristics of high strength, high temperature resistance and waterproof. The photosensitive resin material is easy to harden if it is not used for a long time and has certain toxicity, so it needs to be sealed when it is not used.
In addition, photosensitive materials are expensive and need to be poured into utensils when used, which is easy to lead to waste. But I also believe that the price of consumables will be cheaper and cheaper, and there will be more and more kinds.
Application of photosensitive resin
Photosensitive resin materials with good details and high surface quality can be colored by painting and other processes. However, articles printed with photosensitive resin will gradually become brittle if exposed to light for a long time. This material is mostly used to print fine models which require high model accuracy and surface quality, such as hand-making, jewelry or precision assembly.
Types of photosensitive resins
There are many kinds of photosensitive resin materials, and the subdivided photosensitive resin materials show different properties according to different formulas or manufacturing methods, which are suitable for different fields.
Safety of photosensitive resin
Many people are controversial about whether photosensitive resin is toxic or not. In fact, photosensitive resin materials can not be simply said to be toxic or non-toxic. Toxicity must be discussed in combination with dose. Generally, there is no problem after normal light curing.
Therefore, users who are worried that the photosensitive resin material is toxic and will cause harm to the human body can rest assured that as long as the photosensitive resin material you buy is normal, except for the ventilation protection during printing, the articles formed by 3D printing are non-toxic and can be used and contacted with confidence.
There are few organic volatiles in photosensitive resin, which will not cause us great harm, but for those professionals who often use light-cured 3D printers, it is best to wear gloves during use and cleaning.
Some people with sensitive skin should pay attention. Everyone has different constitutions, some people are allergic, and some people are not allergic. For those of us who specialize in operating light-cured 3D printers, we usually bring gloves and masks and put them in an independent workshop to make the air circulate well and prepare clean alcohol. This practice shows that we are not only more professional in operation, but also more convenient in handling models and keeping the printing room clean and tidy.
