There are a few different varieties of 3D printers available in the competitive market today. Thanks to the development of technology and several companies venturing this product a range of 3D printers can be found. From SLA to DLP and everything in between including Selective Laser Sintering (SLS), Fused Deposition Modeling (FDM), Digital Light Process (DLP), Multi Jet Fusion (MJF), PolyJet, Direct Metal Laser Sintering (DMLS), and Electron Beam Melting (EBM). 

With that long list, it is important to sort your priorities and the reasons why you need to buy a 3D printer. Is it for a business? Will it be used in small-scale production or industrial grade? According to these answers, you will be able to decide on the type of printer you need. 

In simple words, if you need a high-quality, professional-grade 3D printer you will need to get one of the high-end products with a bigger budget. 

2. Printing Speed

3D printing is not a fast process. It takes time to develop that precision and get the fine detailing just right. That being said, companies are working to develop on this aspect and the various other models. So always check this factor while browsing for the right 3D printer.

3. Build Volume

Build Volume is one of the most important criteria to understand while purchasing a 3D printer. In simple words, build volume is the dimension of the models that can be created using a particular printer. So, if you are buying a 3D printer for DIYs, or smaller production outputs, any average printer should do. 3D printers with a large build volume are feasible for bigger models, but they take more time to create the prototypes. 

4. Printing Quality

The most obvious factor to consider is the quality of the prints. Particulars like resolution, pixels, anti-aliasing technology, and most importantly the slicing software is what decides the end quality of the model. Apart from these basic properties other aspects to keep in mind include machine noise, user-friendliness, smoothness, and added features. 

5. Affordability 

The final decision is ultimately based on your budget. These days a range of products are accessible in almost any price range. One thing to think of is that buying a 3D printer is not something you’re bound to do very often. Any piece of technology you purchase, you are going to want it to last for several years–a one-time-buy. So investing a little bit in one of the best SLA 3D printers is probably a smart decision.  

6. Durability 

Since 3D printers are not something you are not going to buy very often, it is crucial to test the durability of the product and its components. Generally, printers with all-metal or aluminum bodies are considered to be strong and are not easily damaged. 

FAQs on Resin 3D Printers

Q1. What Is SLA?

SLA, or Stereolithography, printing is the most widely used 3D printing technology. It was first developed at the beginning of the 1980s by Japanese researcher Hideo Kodama. Kodama invented the modern layered approach to stereolithography by using ultraviolet light to cure photosensitive polymers.

SLA is an additive manufacturing process that uses an ultraviolet (UV) laser on a vat of photopolymer resin. Aided by slicing software (CAM/CAD), the laser draws a pre-programmed design onto the surface of the photopolymer vat. The resin is photochemically solidified and forms a single layer of the 3D design. The process is repeated to build layers one on top of the other and finally builds the end product. 

Q2. Why Use Resin?

The liquid material generally used in SLA printers is called ‘resins.’ Resins are thermoset polymers. Standard resins result in high stiffness, high-resolution prints, which also gives a smooth injection molding-like finish. To top that, resins are low in cost, making it feasible for prototypes. 

Q3. What Are The Different Types Of Resin? 

Standard resin or more commonly known as just ‘resin’ is the most popular choice for SLA 3D printing. But other options include:

  • Glass-reinforced resin- Glass additives are mixed for extra strength and stability. Prints are rigid and do not easily deform.
  • Durable resin – This is used to design parts that undergo mechanical stress and wear. 
  • Flexible resin – This type solidifies to a rubber-like substance. It is used for elasticity and flexibility. 
  • Tough resin – Also called ‘ab-like’ material, used for increased stiffness in heavy-duty models.  
  • Dental resin – Photopolymers that are biocompatible are used in the medical field like dentistry to form products like retainers.
  • Shell casting resin – This is a form of resin used in shell casting to create soft parts.
  • Ceramic resin – A photopolymer with ceramic additives used to replicate objects made of ceramics.
  • High-detail resin – These resins have various names depending on the company you buy from. But the common property is that it helps to get better resolution in the prints as it reacts better when exposed to a light source. 

Q4. What Types Of Resin Printers Are Out There? 

There is a wide range of resin 3D printers available in the market, today. The most popular types are Digital Light Processing ( DLP) printers and Stereolithography (SLA)printers.

Q5. What Are The Post-printing Steps For A Resin Prototype?

Resin 3D printers require a post-printing procedure to reach the end-product. These involve the following steps:

  • Washing: The model is washed by dipping into alcohol or water, or at the very least is left to dry to remove all the residual uncured resin.
  • UV Curing: The print is hardened under a UV lamp to solidify and strengthen the model. 
  • Support Removal: Resin printing involves using support to create the structure. After the print is formed, this support is removed. 

Additional (optional) post-processing steps include sanding, patching escape holes, finishing, painting, and polishing. These may be done either manually or by using special pieces of equipment. 

Q6. What Are The Applications Of 3D Printers? 

  • Prototyping and Manufacturing: The primary use of 3D printing was prototyping and production. It was meant to speed up the production process by creating single molds much faster. It also significantly reduced lead times required in traditional manufacturing. 
  • Medicine: For the past several years, many 3D printing applications have been introduced in the world of medicine. The areas of bioprinting, where biomaterials (cells and growth factors) are joined to form tissue-like replicas of their biological counterparts, prosthetics, assistance in surgery, etc. have seen success with 3D  printing.
  • Construction: The technology of 3D printing allows engineers and architects to study and plan the construction of complex infrastructures. Printing is used in the fields of extrusion (concrete/cement, wax, foam, and polymers), powder bonding (polymer bond, reactive bond, sintering), and additive welding.
  • Education: With the increased accessibility, students are getting the opportunity to learn 3D printing and designing. It helps to prepare the students by studying and creating prototypes without having to spend loads of money on expensive equipment. 3D printing fills in the gap between images on paper and theory and real-life models and structures. 
  • Art and Jewelry: You may think that 3D printing has no use in the art department, but you’re wrong. An unexpected venture for this new innovation can be seen with artists and jewelry designers. 3D models allow them to play with ideas and experiment with designs as testers before forming the final product.
