What Printed Composite Tooling Brings to the Table: Four LSAM Projects

Posted by Duane Marrett on Thu, Oct 29, 2026

Tags: Thermwood, Composites, tooling, aerospace, LSAM, Test Results, case studies

For most manufacturers, the question isn't which 3D printer to buy.  It's whether printed composite tooling belongs in their operation at all.

The answer comes down to results.  Here's what four very different projects have shown.

Drone body concept design, LSAM printed tool set and finished composite part

From concept design, to printed tool set, to finished part: a two-sided drone layup tool printed on LSAM.

1. Printed vs. Traditional, Head to Head

Aria Composite Technologies and Purdue University

LSAM printed tool vs. traditional method: 24.4% material cost reduction, 34.8% total cost reduction, 39.2% labor cost reduction, 75% creation time improvement

To compare the two approaches directly, Thermwood, Aria Composite Technologies and Purdue University's Composite Manufacturing and Simulation Center (CMSC) built a two-sided autoclave layup tool for a blended wing drone body two ways: by the traditional method, and printed on an LSAM in 20% carbon fiber reinforced polycarbonate.  The LSAM tool outperformed the traditional method in cost, speed and overall performance.

  • Tool cost: $8,500 traditional vs. $5,539.50 printed
  • Time to tool: 10–12 days traditional vs. 3 days printed
  • 34.8% total cost reduction, including 39.2% lower labor cost
  • 75% faster tool creation

"Tools were easier to work with, excellent performance with no signs of wear after 6 complete cycles on each half."

Kevin Cain, Chief Technology Officer, Aria Group

2. Save at Production Scale

General Atomics

General Atomics needed a large CNC trim tool.  Printed on an LSAM in ABS with 20% carbon fiber and then machined to final shape, the 1,190 lb tool came in at about $50,000 less than traditional methods.

  • Lead time cut from 6–8 weeks to under 2
  • 2–3x cost reduction
  • 3–4x faster development
  • A production-capable tool with vacuum integrity, no coatings needed

See the full General Atomics story

3. Bring Tooling In-House

D-J Engineering

Video: How D-J Engineering transformed tooling with LSAM

Aerospace manufacturer D-J Engineering of Augusta, Kansas stopped waiting on outside tool shops.  With its own LSAM, D-J now produces stretch form blocks, mill fixtures and complex aerospace tooling in weeks instead of months.

"LSAM has completely upended what we can do."

Tyler Hieber, Engineering Manager, D-J Engineering

4. Move Faster on New Designs

Tidal Blade Research, with Purdue, Sheffield and Oxford

Video: Tidal blade mold tool being printed on a Thermwood LSAM AP 510

When a design is still evolving, waiting months on every tool slows progress.  For a 2-meter tidal turbine blade developed by the Universities of Sheffield and Oxford, a double-sided infusion tool was printed on an LSAM in carbon fiber reinforced polycarbonate, cutting tooling time from months to weeks.

  • Purdue's ADDITIVE3D simulation predicted the print before the first layer went down
  • Sheffield's AMRC machined in sensor slots, root mounts and resin ports
  • When the design changes, the next tool can be printed again in weeks

The Common Thread

Lower tooling costs.  Shorter lead times.  The freedom to change a design without starting over.  And tooling built under your own roof, on your own schedule.

Why LSAM

LSAM prints and trims on one system, so a tool goes from file to finished part in one place.  It's built by Thermwood, a machine tool company with 55+ years of experience, and it's already producing tooling for aerospace, defense, marine and energy manufacturers.

Unlock Unmatched Internal Strength with LSAM Print3D’s Brace Feature

Posted by Duane Marrett on Thu, Jun 05, 2025

Tags: Additive, LSAM, Additive Manufacturing, LFAM, LSAM Print 3D, Brace Feature


Transform Large-Scale Prints with Custom Internal Bracing

In large-scale additive manufacturing, traditional infill strategies often fall short—especially for complex, high-performance applications like autoclave tooling and CNC fixtures.

That’s why LSAM Print3D’s patent-pending Brace feature gives users the ability to design and place custom internal bracing directly within the part.

✔️ Precisely positioned internal support—exactly where it’s needed
✔️ Surface- or solid-based geometry with near-limitless complexity
✔️ Automatic connections along curved and compound boundaries
✔️ Stronger parts, smarter material use—no overbuilding required

From simple headers to intricate support structures, the Brace feature enhances strength and performance without compromising your design.

Just one of the many powerful capabilities that sets LSAM Print3D apart.

Engineered for flexibility. Built for performance. Powered by Thermwood.

Highlights from the recent IMTS show held in Chicago!

IMTS 2024 Recap

It was a pleasure to showcase our innovative technologies, including the LSAM (Large Scale Additive Manufacturing) Additive Printer 510, which printed live, high-temperature (350°F) autoclave-capable aerospace tooling throughout the event!

Each day, we featured a different high-temperature material from leading 3DP material providers. Two tools were printed daily, each tool weighing 215 lbs and printed in 5 hours.

Purdue CMSC on hand at IMTS
We were also proud to highlight our collaboration with Purdue University’s Composites Manufacturing & Simulation Center (CMSC). The printed autoclave tool incorporated Purdue’s ADDITIVE3D simulation process to predict and compensate for shape changes due to residual stresses, interlayer bonding and deformation. Full scale tool samples showcasing vacuum integrity, surface quality and part precision were displayed for attendees.

Cut Layer Additive (CLA) Featured at IMTS

In addition, we featured our Cut Layer Additive (CLA) manufacturing process, a cutting-edge approach for creating tools, patterns and molds using sliced layer lamination. CLA enables the use of materials that are not 3D-printable and integrates features for vacuum, coolant and assembly – representing the future of mold manufacturing.
