About the LSAM Additive Printer

The LSAM Additive Printer systems are single gantry, moving table configurations and are available in two table sizes, 5’x5’ and 5’x10’. The 5’x10’ table is available in two configurations, 5’ wide with 10’ of front to back motion and 10’ wide with 5’ of front to back motion. Choice of configuration depends on several factors, fitting it existing factory floor space is one factor.

The specially designed, highly rigid tab and slot, structural steel gantry also incorporates a fume extraction system that pulls print fumes through specially designed activated charcoal filters to remove them and “sweeten” the air.

LSAM Additive Printers use the exact same print head mechanism as all the others, including the largest LSAM Systems which means that they produce the same amazing print quality that has made LSAM the leader in large scale additive printing. They also use the same highly advanced Ultra 6 control with all its exclusive, patented print features and capability.

The systems come standard with a single hopper polymer dryer for applications that don’t change print material very often. For installations that print a wider variety of materials, a dual hopper dryer is available as an option.

An enclosure that surrounds the machine is also available. The machine with the full enclosure can also be built to meet European CE standards.

Award to Develop Additive Manufacturing of Modular Wind Blades

The U.S. Department of Energy (DOE) has announced an award of $2,849,000 to the Composites Manufacturing Simulation Center (CMSC) of Purdue University and its industry partners, including Thermwood, TPI Composites Inc.Dassault Systèmes, Dimensional Innovations and Techmer PM.

The DOE-funded Purdue program, “Additive Manufacturing of Modular Tools with Integrated Heating for Large-Scale Wind Blade Manufacturing,” is led by Eduardo Barocio, director of the Composites Additive Manufacturing and Simulation (CAMS) Industrial Consortium.

“The primary goal of the program is to develop the foundation for automation in manufacturing of tooling for large-scale wind blades that can accommodate continuous changes in blade geometry and scale,” Barocio said. “This will be accomplished through modular construction, wherein modules are 3D printed with carbon fiber/thermoplastic composites by a technology called extrusion deposition additive manufacturing, which was first developed at the DOE’s Manufacturing Demonstration Facility in the Oak Ridge National Laboratory.”

Specific targets for the program include developing a module design for wind blades equal to or greater in length than 80 meters; reducing the time required to manufacture and assemble wind blade tooling by at least 40% over conventional tool manufacture; enhancing tool performance by at least 15%; effecting weight reductions of by a minimum of 25% over conventional tools; and lowering the manufacturing cost of a wind blade tool by at least 35%.

Barocio is founder and director of the Thermwood LSAM (Large-Scale Additive Manufacturing) Research Lab at the Indiana Manufacturing Institute in Purdue Research Park. He is also founding director of the Composites Additive Manufacturing and Simulation Industrial Consortium, whose mission is to shape the future of large-scale additive manufacturing by providing education, simulation tools, characterization and best practices.

“The proposed program provides the foundation for automated manufacturing technology in wind blade tooling manufacture,” Barocio said. “These same technologies can be applied to manufacturing of all the elements of the wind energy system and, as such, the program provides a pioneering development that can leverage technology within the United States for a major source of clean energy, wind.”

The program will develop and demonstrate seven specific innovations. These include automating the 3D printing of large-scale modules and developing robust joining technology and inline heating elements deposition for conduction heating. Others include 3D printed cooling channels for convective cooling; new composite materials systems for economy and performance; support frame weight reduction; and tool deformation prediction and control, with decision making by a digital twin for 3D printing design and manufacturing.

Overall, the DOE awarded $30 million for 13 projects across 10 states that will reshape the design, materials and sustainability of large wind blades for offshore and land-based applications.  Large wind blades face significant challenges in design and materials, particularly for offshore applications. The selected projects will tackle these challenges, focusing on sustainability, efficiency and technological advancements to make wind energy more viable and effective.

Advanced lightweight composite materials have emerged as pivotal in enhancing wind power generation and vehicular applications. The DOE projects were picked for their potential to bolster the manufacturability and robustness of these composite materials, which are essential to the future success of wind energy technologies. The projects focus on three primary challenges: large wind blade additive manufacturing, additive manufacturing of wind turbine components and advanced manufacturing, materials and sustainability for large wind blades.

“These projects, alongside the Purdue program, will address the remaining challenges in wind turbine manufacturing and build on previous work in automation, digitalization, wind blade sustainability and modular blade construction and joining,” said R. Byron Pipes, executive director of the Composites Manufacturing Simulation Center at Purdue. “Successful demonstration of automation in the manufacture of alternate energy systems can enhance their wider use while sustaining the industry in the United States.”

 LSAM Research Lab at Purdue Enables CERN Particle Collider Upgrade Prototyping

Posted by Duane Marrett on Tue, Apr 12, 2022

Purdue CMSC, in collaboration with Purdue Silicon Detector Laboratory (PSDL), is designing, prototyping, testing, and fabricating composite support structures for CERN’s Large Hadron Collider (LHC) CMS and ATLAS experiments. This is part of the particle collider’s High Luminosity upgrade, with installation of final components in 2026-27. The Thermwood LSAM 105 Additive Printer and five-axis LSAM Trim router at the Purdue LSAM Research Laboratory have enabled rapid large-scale printing and machining of trimming fixtures for the high precision composite tube structures. The 1m long, 208mm radius trimming fixture was printed on the LSAM with Acrylonitrile Butadiene Styrene (ABS) reinforced with 20% by weight of carbon fiber.

Thermwood LSAM Research Laboratory at Purdue University

This 914mm long prototype of the CMS upgrade inner tracker support tube will allow project partners at national labs, universities around the world, and CERN to begin installation tests of their structural and detection components. Individual components installed into this support tube are expected to be positioned within +/- 0.5mm or less, so accurate machining of interface features is critical. This kind of precision at large scale is made possible, economical, and convenient with the aid of systems like LSAM.

Printing Details

Printing Details

Since critical surfaces would be machined later, and to increase production speed for the prismatic geometry, the tool was split into two vertically-printed segments. The halves were bonded with adhesive and dowel pins for joint strength and stability.

Printing Details - closer look

Machining Details

The faces that would become the trimming fixture base were machined to the flatness required for fixturing later. The printed, bonded fixture was then mounted on pedestals in the LSAM Additive Trimmer and the surface was machined to fit the nominal inner surface shape of the composites half-cylinders to be trimmed. Edge finding and reference features were machined into the trimming fixture to allow proper centering of the cured composite part.

Printing detail - closeup

Using this printed and machined fixture, the composite part edges were trimmed, interface holes drilled, mating surfaces machined flat and a scarf joint for joining the two half cylinders was created. The precision trimmed composite halves were then able to be bonded together.

Final Result

The final tube, 3.2m long, has to support 140kg of mass while only allowing sub millimeter deflections to occur. Purdue CMSC and PSDL will also be designing, fabricating, or testing other composite support structures for the CERN LHC upgrade as small as 0.5mm sheet goods and as large as 2.4m x 5m sandwich panel tubes. It is planned for the LSAM system to be utilized to create tooling and some final components for these other structures.

About the Thermwood LSAM Reseach Laboratory at Purdue University

The new laboratory will be equipped with an LSAM 105 (ten-five) Large Scale Additive Printer and a corresponding 5 axis LSAM Additive Trimmer plus a variety of support systems. This installation is capable of printing and trimming complex geometries up to five feet by ten feet by four feet tall at print rates of up to 200 lbs. per hour. Commercial maximum print temperature for LSAM printers is usually limited to 450oC, however, this particular system has been modified to allow testing at even higher temperatures for experimentation with innovations in materials normally not used in additive manufacturing.

This effort will be enhanced with the newly announced ability of Thermwood’s LSAM large scale additive manufacturing systems to measure and precisely control the temperature of a printed layer at the instant a new layer is deposited. This will support research into the very core of the additive print process and will serve to provide validation of Purdue’s extensive additive manufacturing simulation capabilities for large scale additive manufacturing.


Not only will this effort improve the overall quality of large scale additive printing but it should also increase our knowledge and understanding of the basic process of fusing layers together into a homogeneous structure”
says Ken Susnjara, Founder, Chairman and CEO of Thermwood.


Extrusion deposition composites additive manufacturing is a major innovation that will contribute to the development of tailored products with unique performance and just in time availability.”  
Adds Dr. R. Byron Pipes, Executive Director of Purdue’s Composite Manufacturing & Simulation Center, the research organization where the LSAM system will be installed.


Purdue plans to partner with industry to provide services to enhance, encourage and expand the adoption of large-scale additive manufacturing for diverse industrial applications. They also plan to work with polymer suppliers to refine formulations and determine the ideal processing parameters necessary to produce the absolute highest quality large scale printed parts possible.

Collaborative efforts of this type bring together diverse organizations that each specialize in different aspects of this emerging technology and often produce results that none of the participants could possibly achieve on their own. Both Purdue and Thermwood are confident that this will be the outcome of their collaborative effort.

Thermwood and Purdue Successfully Compression Mold Parts Using Printed Tooling

Posted by Duane Marrett on Mon, Nov 11, 2019

Tags: Thermwood, Announcements, Purdue, 3D printing, Additive, LSAM, Compression


Thermwood and Purdue’s Composite Manufacturing & Simulation Center have been working together to develop and test methods of using 3D printed composite molds for the compression molding of thermoset parts. They have just announced that they have successfully been able to compression mold test parts using 3D printed composite tooling.

Thermwood and Purdue’s Composite Manufacturing & Simulation Center have been working together to develop and test methods of using 3D printed composite molds for the compression molding of thermoset parts. They have just announced that they have successfully been able to compression mold test parts using 3D printed composite tooling.

Final part has over 50% carbon fiber volume

The test part, a half scale thrust reverser blocker door for a jet engine, was designed at Purdue and is approximately 10x13x2 inch in size. The two-part matched compression mold for the part was 3D printed using Techmer PM 25% carbon fiber reinforced PESU at Thermwood, using its LSAM large scale additive manufacturing system.

The mold halves were then machined to final size and shape on the same system. The completed tool was next taken to Purdue’s Composite Manufacturing & Simulation Center, in West Lafayette Indiana, where it was mounted to their 250 ton compression press. Parts were then molded from Dow’s new Vorafuse prepreg platelet material system with over 50% carbon fiber volume fraction.

The Details

Both halves of the mold were printed at the same time during a single 2 hour and 34 minute print cycle. When using Thermwood’s “continuous cooling” print process, the polymer cooling determines the cycle time for each layer, allowing both halves to be printed in the same time it would take to print one half (since both parts could be printed in the layer cooling time available).

Both halves of the mold were printed in less then 3 hours

Both halves of the mold were printed in less than 3 hours

Machining, however, must be done in the traditional manner, one part at a time, although there is an advantage to machining printed parts. Since the part is printed to near net shape, the overall amount of material that must be removed is significantly less than if the tool was machined from a solid block. Machining of the two mold halves required an additional 27 hours.

The first attempt at compression molding was not successful, but techniques were developed to account for the mechanical and thermal conductivity characteristics of the polymer print material and a second attempt produced acceptable parts.

The team determined that using printed composite molds in a compression press does require a significantly different approach than a tool for the same part machined from a block of metal. First, the tool must be internally heated since the polymer composite doesn’t transmit heat as well as metal. Thermwood developed a technique for deep hole boring of the printed composite part using the trim head on its LSAM machine, allowing the deep insertion of cartridge heaters.

A special heat control allows the temperature of various areas of the tool to be controlled independently, helping address the challenge of balancing the thermal characteristics of the thermoplastic composite mold with the processing temperature requirements of the thermoset material being processed.

Also, the outside of the mold must be reinforced so that the composite polymer used for the mold itself is under only compression loads and not tension during the molding operation, since forces developed during molding are greater than the tensile strength of the composite polymers used for the mold. This approach has successfully withstood molding pressure of 1,500 PSI during initial testing and the team believes even higher pressures are possible.

Final Thoughts

Both Thermwood and Purdue believe this is an important first step in bringing additive manufacturing to compression molding. The speed and relatively low cost of printed compression tools has the potential to significantly modify current industry practices. Printed tools are ideal for prototyping and can potentially avoid problems with long lead time, expensive production tools by validating the design before a final version is built.

Additional development effort will be needed to further refine tool design and broaden the range of parts that this process will support, but all parties involved believe that this project demonstrates the viability of the basic approach.

Potential applications in the auto industry include prototyping and production tool verification. Because of high volume requirements for auto production, it is unlikely that these tools would function adequately for full production use, but actual useful production life is still unknown. It will require additional testing to determine just how many parts can be molded from an additive manufactured compression mold and what the ultimate failure mode actually is.

In aerospace, parts tend to be much larger and production volumes much lower, so it is possible that printed compression molds could find actual production use for larger, lower volume aerospace components, perhaps replacing open face tools and autoclaves for certain parts.

The relatively low cost and fast build rate of these additive molds significantly alters the decision matrix and timeline for developing new products using compression molding.
