Large format resin 3D printer selection for professionals


A large resin 3D printer is an excellent choice for professionals looking to produce high-quality prototypes and end-use parts. Small build volumes and expensive pricing used to be limiting factors for many, but new technology is presently addressing both of those issues. In this article, we take a look at some of the best large volume resin 3D printers for professionals.

Large resin 3D printers: a new trend?

Stereolithography (SLA) has been around for decades, with two main sub-technologies: laser SLA and DLP (Digital Light Processing). These 3D printing methods offer highly accurate and smooth results, but are generally limited to small build volumes, unless you’re looking at industrial systems worth several hundred thousand dollars.

However, a third SLA sub-technology has recently made its way to the market: MSLA (Masked Stereolithography). In short, MSLA 3D printers use LCD screens as light masks over LED lights, simplifying the resin 3D printing process and drastically bringing prices down.

On that account, large volume resin 3D printers are now affordable enough (and actually available on the market) for SMEs and entrepreneurs, whether it’s for prototyping or small production series.

That said, there aren’t many options yet, as you can see in our large format resin 3D printer selection below. This selection is based on large resin printers that are priced under $20,000, hence excluding large industrial SLA printers which we’ll soon cover in another guide.

Our guide also covers the main pros and cons of resin 3D printing, which resin materials are available, and how fast resin printers are.

Resin 3D printing: main takeaways

We highlight a few of the key advantages of using a resin 3D printer while also touching on a few of the cons.

SLA vs FDM vs SLS

While many FDM 3D printers offer bigger build volumes, resin 3D printers provide much smoother results in terms of accuracy and surface quality. In this price range, the only kind of printer that could potentially match resin printing quality would be a desktop SLS 3D printer. There’s a very limited range of available powder types and colors, however.

Benefits of resin printing

These are some of the main, high-level advantages of resin 3D printing.

  • Smooth surface finishes – Resin printers are able to produce very thin layers that are barely visible to the human eye, if not invisible.
  • High level of details – It’s possible to print complex, intricate models with tight tolerances.
  • Unique resins – The selection of specialty resins is quite impressive, from colored or transparent resins to strong, rubbery, or castable resins.
  • Speed* – Whether you print one small object, several parts, or one large model (all either simple or intricate) of the same height, the overall print time will be the same.

*Does not apply to laser-based SLA 3D printers.

Resin 3D printing drawbacks

While resin 3D printing offers compelling advantages, there are still a few things you may want to keep in mind.

  • Material prices – Resin can be expensive, especially if the system you choose doesn’t work with third-party resins.
  • Post-processing – Prints must be washed and then cured with a UV light or sunlight. Most manufacturers sell separate, dedicated “stations” for these steps to make them less troublesome.
  • Toxicity (and smell) – It’s important and necessary to wear gloves, and working in the same room as an active resin 3D printer is highly discouraged.

3D printing resins: what materials are available?

Most manufacturers sell basic or standard resins in several colors, plus specialty resins for different kinds of applications. Here are some common types of resin:

  • Biocompatible
  • Castable
  • Transparent
  • Hard
  • High tensile
  • Temperature-resistant
  • Flexible

Not all resins are compatible with all resin printers, and some resin printers only tolerate their manufacturer’s proprietary materials (e.g. Formlabs). This is true for other technologies, too, such as FDM/FFF, e.g. Stratasys with proprietary filaments, or SLS, with almost all manufacturers curbing compatibility.

Resins can also be specially formulated for certain types of technologies. For example, MSLA printers won’t be able to cure resins made for laser SLA printers. This is partly because they use a less powerful light source.

Resin 3D printing: how fast is it?

Resin 3D printing speeds are generally listed in one of two ways:

  • As a maximum height reached in certain amount of time (mm/minute, cm/hour)
  • As the amount of time it takes to cure one layer (seconds/layer, layers/minute)

It’s a good idea to keep resin 3D printing speeds in mind, even if a variety of factors– namely layer thickness and type of resin– make that number hard to narrow down. For reference, the PartPro 120 xP from XYZprinting is currently one of the fastest 3D printers on the market. It’s capable of printing a 3-cm-tall part in only 10 minutes, while some resin printers would require over an hour.

FAQ

What’s the largest resin 3D printer available?

At the moment, that would be the UnionTech RS Pro 2100, which happens to be an industrial SLA printer. This massive machine has a build area of 2100mm x 700mm x 800mm.

Is 3D printing resin toxic?

Yes, while toxicity levels can vary, resin is something you’ll want to keep off your skin and out of your eyes. Gloves and protective eyewear are necessities when working with any type of resin.
