Why is resin used in 3D printing?

Resins are a big part of materials research within 3D printing, and are ideal for quickly producing parts with a high level of accuracy. 3D printing resins are liquid photopolymers, primarily used with technologies such as Stereolithography (SLA) and Material Jetting.

What does resin do in 3D printing?

It works by exposing a layer of photosensitive liquid resin to a UV-laser beam; the resin then hardens in the desired pattern, and the object is built layer by layer until it is complete. This allows you to print a model with extremely fine detail.

How much resin does a 3D printer use?

500ml of resin can last the average user around 2 weeks of normal use when printing small models on a regular basis. You could use 500ml of resin in a few really large 3D prints, which could take 2 or 3 days. 1 liter of resin can last you anywhere from 5 days to a month of printing.

What are the advantages of resin printers?

  • Resin printers offer much more detailed and smooth models.
  • Resin prints don’t require extensive post-print finishing to look good.
  • They are faster than FDM machines.
  • Resin models are generally stronger and more resilient.

How long does resin printing take?

Larger models that take up most of the build volume of an SLA printer (around a 15 cm cube) take only around nine hours to print with Draft Resin. Printing the same part at 200-micron layers on an FDM printer can take 80-90 hours.
