Virtually all, if not all, large format, FDM additive systems, sold to industry in the last several years have been Thermwood LSAMs.

Watch the video below to learn 21 reasons why:

Thermwood routinely applies for patent protection on additive manufacturing technology it develops for its LSAM large format additive systems. During COVID, we received electronic copies of patents that were granted, however, the official hard copies were withheld.

A couple of days before Christmas 2021, we received a package containing the official hard copy of 32 additive manufacturing patents. This was certainly a one-day record for Thermwood and a welcome sight!

In addition to these latest patents, Thermwood already has a large portfolio of earlier issued patents covering the unique, large format (5x10 foot table and larger) 3D print technology it has developed. This LSAM technology is currently the most widely used large scale additive print technology operating in industry today. It’s used in a wide variety of industries including aerospace, transportation, heavy equipment, foundry and large decorative structures. It is being used to produce a diversity of products including aerospace patterns, molds and tooling, heavy equipment foundry patterns, bus chassis, large valve body foundry patterns and trim tooling. It was even used to print the tallest 3D printed structure in the world, the 92 foot tall Al Davis Memorial Torch at Allegiant stadium in Las Vegas.

Thermwood offers this unique patented technology on a wide variety of equipment, the largest, most diverse product offering of its kind available today. It includes a broad selection of machines, including single and dual gantry, fixed and moving table configurations, with both print-only and print-and-trim systems, from 5 by 10 foot to 20 by 60 foot print envelopes. We are working on even larger machines but that’s for another day.

The primary focus of the patented LSAM technology is to reliably and repeatedly produce the highest quality, best fused, most homogeneous printed structures possible from a variety of reinforced thermoplastic polymer composites including those intended to operate at elevated temperatures. Although it is nice to have been granted these patents, it is even nicer to finally have the official hard copies in hand.

Thermwood has added a third print orientation to its LSAM Large Scale Additive Manufacturing systems.

LSAM systems currently can print both horizontal and vertical layers if equipped with the Vertical Layer Print (VLP) option, available on most Thermwood LSAM machines. This new addition adds Angle Layer Printing (ALP) to the VLP option. Angle Layer Printing is the ability to print at a 45 degree angle.

Maximum Print Flexibility

Each print orientation has advantages and limitations for a particular part design. Offering all three on the same machine, for the first time, means maximum print flexibility. All print orientations use the complete LSAM print head including exclusive LSAM print features such as the patented compression wheel and Thermal Sensor Layer Automation.

This helps maintain an even layer temperature throughout the print.  LSAM automatically adjusts the individual layer temperature to provide for superior layer fusion (as seen below).

LSAM machines are currently operating in regular daily industrial production with many existing systems already equipped with Vertical Layer Print capability. The Vertical Layer Print (VLP) option has been replaced with a VLP/ALP option on new machines which offers both vertical and angle layer print capability, in addition to the standard horizontal layer print.

Angle Layer Print (ALP) can be easily and inexpensively added to machines operating in the field that already have the VLP option.

If a machine was purchased without VLP, the entire new VLP/ALP Print option, can be added to most machines already in operation. It can be done in the field, but is a bit more involved.

Broad Line of LSAM Systems Available

Thermwood’s LSAM large scale additive systems are the most widely used large scale composite thermoplastic additive equipment in industrial production today. Virtually all, if not all, large scale additive systems installed in the last several years have been Thermwood LSAMs. Processing a variety of reinforced composite polymers from room temperature ABS and PC to high temperature material such as PSU, PESU and PEI, they are used to produce molds and tools for the aerospace industry, patterns for the foundry industry and for a variety of other unique applications.

LSAM systems are available in sizes from 5x10 foot to 15x60 foot in a variety of configurations including print only and full print and trim, making it the broadest product offering in the large scale additive arena. Print heads are available that can print thermoplastic composite material at rates from 200 pounds per hour to over 500 pounds per hour.

They have a variety of exclusive features including a temperature controlled compression wheel and automatic thermal layer speed control, both of which help assure the best possible fusion between printed layers.

With the addition of Angle Layer Print, these systems have become even more capable and more flexible.

Experts say so at industry seminars, however, major aerospace companies 3D print molds every day that don’t have void or porosity problems. How can this be?

Watch the 8 minute video below and learn the simple answer.

Dale, Indiana based Thermwood Corporation will enter into an LSAM/Thermwood sponsorship arrangement with Columbus, Ohio based Alliance Autosport for one of Thermwood’s own employees. The employee will be racing in the Sports Car Club of America (SCCA) “Runoffs” at the famed Indianapolis Motor Speedway during the last week of September and into October.

The Runoffs is the SCCA’s annual winner-take-all national championship. The competition brings together the best qualified amateur racers from all over the US and Canada to compete across 26 different race car classes for the 58th consecutive year.

The young driver, Gabe Fehribach, is a member of Thermwood’s engineering team. Gabe fulfilled his Runoffs qualification requirements earlier this year after racing at such storied venues as VIRginia International Raceway, Circuit of the Americas, Mid-Ohio Sports Car Course, and Watkins Glen International, among others.

Following three days of qualifying beginning September 28th, Gabe will compete with his winged, open-wheel SCCA Enterprises Formula Enterprises 2 race car the morning of Friday, October 1st against 28 other drivers all running the same spec chassis, Sunoco fuel, Hoosier tires, and Mazda power unit.

Tickets for the three days of racing beginning October 1st can be purchased through the Indianapolis Motor Speedway website.
