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!

Thermwood Receives 32 Additive Manufacturing Patents

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.LSAM offers the broadest line of large scale additive systems available in the market today

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.

About The Thermwood LSAM

Thermwood offers a line of dual gantry additive manufacturing machines which both print and trim parts on the same machine. These are large industrial additive manufacturing machines that can be up to 100 feet long.  Thermwood LSAM 10'x20'

LSAM (pronounced L-sam) represents an all new technology for large scale 3D printing of thermoplastic polymers. While other large scale additive efforts attempt to scale up small, filament-fed desktop printer techniques, LSAM is, at its core, designed for additive manufacturing of large structures using a fundamentally different approach

LSAM is different. The print process is different. The machine is different. The print head is different. The control is different. The software is different and the resulting parts are different.

LSAM is intended for industrial production. It is not a lab, evaluation or demonstration machine, but is instead a full-fledged industrial additive manufacturing system intended for the production of large scale components.

Although suitable for producing a wide variety of components, Thermwood is focusing on producing industrial tooling, masters, patterns, molds and production fixtures for a variety of industries including aerospace, automotive, foundry and boating.

World's First 3D Printed Car Machined on Thermwood Model 70 at IMTS 2014

Thermwood participated at the 2014 IMTS (International Manufacturing Technology Show) in Chicago, as a part of the world's first 3D printed car team.  

This ambitious undertaking was conceived by Local Motors and carried out by several partners on the project, including Thermwood.  The overall concept was to 3D print, trim, assemble and drive the car all in the one-week time frame of the IMTS show in front of the over 100,000 attendees during the week.

After the car body was 3D printed (the additive portion of the process using a Cincinnati Big Area Additive Manufacturing machine), a Thermwood 5 Axis Model 70 10x15 CNC router was used as the subtractive portion to trim and shape the body into the final streamlined version. This process had to be precise to achieve the correct fit and finish of the body, fenders and all other parts.  

Overall, the entire 3D printing process took 44 hours, machining on the Thermwood took one full day and final assembly was two days!

The Finished Product

After assembly, the finished Strati was ready to roll, and was driven on the last morning of the IMTS show on Saturday September 13th.   This World's First 3D Printed Car begins a lengthy international tour this week.

Local Motors CEO John B. Rogers Jr. (Jay) says in a press release "The Strati was designed by our community, made in our Microfactory and will be driven by you,  This brand-new process disrupts the manufacturing status quo, changes the consumer experience and proves that a car can be born in an entirely different way."
