Build larger, faster, and lighter than ever with ID-Light. Offered only by Stratasys Direct Manufacturing, the ID-Light (Industrial Design Light) process is available with both Stereolithography (SL) and Fused Deposition Modeling (FDM) technologies and features a proprietary scaffolding-like internal structure under a solid surface exterior. This combination allows printing of large, rigid, and accurate geometries at only 1/12th the weight and in a fraction of the time—making it an excellent specialized application for large display models and lightweight fitment prototypes.

ID-Light SL

Ideal for non-structural appearance models, ID-Light SL builds faster, weighs less, and costs less than solid models built with Stereolithography. It also weighs less and has a better paint surface than 10 and 20lbs CNC Machining foam. ID-Light SL is regularly used to create large custom tradeshow marketing figures, architectural models, large detailed props for the entertainment industry, as well as art installation objects.

ID-Light FDM

Stronger and more durable than ID-Light SL, ID-Light FDM, also known as sparse-fill, has the advantage of FDM’s wide range of production thermoplastics. Compared to solid FDM parts, those made with ID-Light FDM are lighter, cheaper, and quicker to build. While the outer shell is not as easy to finish as those made with ID-Light SL, wall thickness can be adjusted for additional smoothing and finishing as needed.

ID-Light Overview

Benefits of ID-Light


ID-Light uses a proprietary process that builds a hard outer shell encompassing a drainable scaffolding-like inner structure. The combination of these two elements makes for extremely lightweight models with a surface that lends itself for pristine cosmetic finish.


Due to ID-Light’s inner scaffolding-like structure, the parts can be built much faster than solid, dense parts.


ID-Light FDM creates parts with a thin outer shell encasing an inner scaffolding-like structure with the same production thermoplastics you would find in injection molding for strong, lightweight models.

ID-Light Applications

ID-Light is ideal for non-structural appearance models. This technology has found success in creating:

ID Light Applications
  • Common applications include:
  • Presentation and concept models
  • Large custom trade-show/marketing figures
  • Entertainment pieces, such as large detailed movie props, promotional figures
  • Art and architectural models
  • Mock-ups
  • Paper pulp molds
  • Vacuum forming molds


3D Printing a Lightweight Replica of the Thomas Jefferson Statue for the Smithsonian

Stratasys Direct Manufacturing partnered with the Smithsonian Museum to 3D Print a life-size replica of Thomas Jefferson. Hand finishing and surface treatments were used to turn the ID-Light, plastic parts into what looked like dense bronze.


ID-Light: Frequently Asked Questions

What makes ID-Light so lightweight?
Stratasys Direct Manufacturing has developed a proprietary process for SL and FDM, which uses a scaffolding-like internal structure to provide strength while reducing the overall weight.
Is there a way to make ID-Light more rigid and impact resistant?
Yes. We can apply a two-part urethane paint to increase rigidity and impact strength.
What Materials Can You Use with ID-Light?
ID-Light parts can be built in FDM with PC-ABS, PC-ISO, PC, ULTEM 9085, ASA, ABS M30, and ABS M30i and in SL with SC 1000.
