LSAM_SeriesRV3_2020_mod.fw-1Thermwood LSAM 2020 - Year in Review

The last 12 months have seen an incredible level of disruption in all industries, fueled in large part by the coronavirus pandemic.  COVID-19 has impacted nearly every aspect of the global economy, from manufacturing to supply chains to travel.

The additive industry wasn’t spared, with event cancellations and disruptions to regular business becoming the norm.  Thermwood pivoted in 2020 to continue our focus on innovation and development with our LSAM (Large Scale Additive Systems) line, and have made many new discoveries and advancements in our additive manufacturing program.

Below, we highlight some of the notable LSAM moments from 2020 that leaves us hopeful for the future of large scale additive manufacturing in 2021 and beyond:

LSAM Info Request


March 5th - Thermwood Announces Another New LSAM Model

Thermwood Introduces the LSAM 1010

To address the need for a lower cost enclosed additive machine, Thermwood developed the LSAM 1010. This system uses the walls from the larger LSAM systems with the gantry, control and sub-systems from the LSAM MT. 

The LSAM 1010 features a fixed 10 foot by 10 foot table. A single moving gantry carries both the print and trim heads as on the MT and, like the MT, it can both print and trim (but not at the same time). The print and trim heads on all Thermwood LSAMs are the same, so all machines can process virtually any reinforced composite thermoplastic materials available today.

With the introduction of the LSAM 1010, it became clear that Thermwood is committed to responding to customer requests and providing its industry-leading LSAM additive manufacturing technology in a variety of configurations to better fit varying customer requirements.


March 17th - Thermwood LSAM 1020 Quickly 3D Prints a Multi-Piece Foundry Pattern

Thermwood Builds Massive Metalworking Machine to Increase LSAM Production

Posted by Duane Marrett on Thu, Jun 25, 2020

Tags: Thermwood, Announcements, LSAM, M400

Thermwood has designed, fabricated and put into operation the largest machine it has ever built. The metalworking machine, dubbed internally as the M400, weighs 51 Tons (103,000 pounds) and is mounted on a special isolated, double steel reinforced concrete pad.  It has a 15 foot wide, 35 foot long floor level steel table that by itself weighs 21,000 pounds.

Thermwood Builds Massive Metalworking Machine to Increase LSAM Production

The massive steel gantry, mounted on parallel walls, moves on four steel rails. It also has a unique feature in that it can be moved up and down by four feet. The Z Axis, mounted on the gantry, has an additional 4 feet of servo travel so that, it is possible to machine parts up to eight foot tall. Moving the entire gantry instead of using an eight foot Z axis results in reduced overhang and significantly higher rigidity and higher quality machined surfaces.

The five axis liquid cooled metalworking head can generate up to 40 HP at speeds up to 20,000 RPM. The Live Load, which is the parts of the machine that move under servo control, weighs 18 Tons, (36,000 pounds). 

Thermwood Builds Massive Metalworking Machine to Increase LSAM Production

The machine is controlled by Thermwood’s Quad Core SuperControl, the same Thermwood designed and built CNC control used on its CNC routers and LSAM systems. This machine is, by far, the largest and heaviest machine built by Thermwood to date and is intended for its own internal production use.

Thermwood Builds Massive Metalworking Machine to Increase LSAM Production

Thermwood has no plans to offer this type of machine for sale, but instead has found that its own increasing demand for large part machining, especially to support growing demand for its LSAM, large scale additive manufacturing machines, required this extraordinary effort. Although the design concept has been in the works for several years, it required about eight months to complete the project and place the machine into production.

Thermwood Announces Another New LSAM Model

Posted by Duane Marrett on Thu, Mar 05, 2020

Tags: Thermwood, Announcements, 3D printing, Additive, LSAM, LSAM 1010

Thermwood recently announced the LSAM MT, a lower cost moving table version of its industry-leading LSAM (large scale additive system). Although Thermwood has hundreds of open moving table CNC routers in operation, similar in configuration to the MT, and believes this configuration will also work for many LSAM customers, several larger customers requested an enclosed machine configuration that is the same size as the MT, but configured like the larger LSAM high wall systems. 

To address this request for a lower cost enclosed machine, Thermwood has announced the LSAM 1010. This system uses the walls from the larger LSAM systems with the gantry, control and sub-systems from the MT.


The new LSAM 1010 has both the print and trim heads on same the gantry just like the LSAM MT.

Although the LSAM 1010 is slightly higher in price than the MT, it is noticeably less than the larger LSAMs and generally less than the cost and complexity of trying to add an external enclosure to the MT.

In addition, even though the LSAM 1010 is slightly wider than the larger LSAMs (to accommodate mounting both the print and trim heads on the same gantry), the overall footprint of the 1010 is actually slightly smaller than required for the MT. And, like the MT, the 1010 can be purchased as a print only machine. 

Thermwood believes that, since it is enclosed like the larger LSAMs, the LSAM 1010 can be built to meet European CE requirements, just like the larger machines.

With the introduction of the LSAM 1010, it is clear that Thermwood is committed to responding to customer requests and providing its industry-leading LSAM additive manufacturing technology in a variety of configurations to better fit varying customer requirements.

CGTech and Thermwood Team up to Simulate Additive & Hybrid Machining

Posted by Duane Marrett on Thu, Feb 27, 2020

Tags: Thermwood, Announcements, 3D printing, Additive, LSAM, LSAM MT, CGTech, Vericut, Simulation

CGTech, makers of industry leading VERICUT software, has partnered with Thermwood to simulate both the additive 3-D Printing and subtractive machining capabilities of their LSAM machines.

LSAM is designed for large scale 3-D printing of thermoplastic polymers. Thermwood’s LSAM machines utilize unique patented technology to produce the highest quality thermoplastic polymer printed structures available. The machines feature both additive and subtractive heads to accommodate printing and trimming of large scale “near net shape” parts on the same machine. Thermwood’s LSAM machines are available in Dual Gantry and Moving Table models, in a variety of sizes. Both systems can process high temperature polymers which are ideal for autoclave capable tooling or compression molds for thermoset materials.

"We have over 55 patented features (and over a dozen more pending) that set the LSAM apart from any other large scale additive system available today.  Features like our chilled roller wheel, vertical layer printing system and LSAM Print 3D software make us the clear leader in large scale additive manufacturing,” says Dennis Palmer, Vice President of Sales at Thermwood. "VERICUT is an important tool to use with LSAM.  It assures that the tool path is correct, eliminating the possibility of expensive mishaps."

Thermwood Introduces New LSAM Model

Posted by Duane Marrett on Mon, Nov 18, 2019

Tags: Thermwood, Announcements, 3D printing, Additive, LSAM, LSAM MT

At its 50th Anniversary Gala Open House, Thermwood introduced and demonstrated an all new LSAM additive manufacturing machine model, offering even more choices for large scale additive manufacturing applications. Called LSAM MT, the new machine offers an all new configuration and significant advantages in certain applications.

The Details

Unlike standard LSAM systems, which feature dual gantries operating over a large fixed table, the MT (which stands for “Moving Table”) features a single fixed gantry mounted over a moving table. Available with a 10x10 foot table, this configuration offers several significant advantages, not the least of which is a dramatically lower price.

Despite the lower price, the LSAM MT is still a massive, robust industrial production machine capable of reliable, day in and day out production. Unlike standard LSAM systems, the MT can be configured as a “Print Only” machine. The logic for this is simple.

Despite the lower price, the LSAM MT is still a massive, robust industrial production machine

New Options

Near net shape printed tools dramatically reduce machining time for many companies currently machining tools from solid blocks of material. This frees up significant machining capacity which is already purchased and installed. For these companies, it makes no sense to purchase additional machining capacity with their additive system, since the change to additive frees up more than enough existing capacity to handle everything they can print. With this in mind, Thermwood decided to offer both “Print and Trim” and a “Print Only” versions of the MT.

The MT is available with a 10 foot by 10 foot table. The 10 x 10 machine actually has a 10 x 12 foot table with a 10 x 10 working area. The extra 2 foot is used to mount an optional Vertical Layer Print table. The 10 x 10 foot MT can be equipped with a new version of Thermwood’s patented Vertical Layer Printing technology. This means that it can make parts up to 10'x10' by 5 foot high using traditional Horizontal Layer Printing or, 5'x10' by 10 foot high using Vertical Layer Printing.

Since the print technology and print heads used on the MT are the same as used on the larger machines it offers the same throughput, print quality and layer to layer fusion that has made LSAM the leader in large scale additive manufacturing. As with the larger systems, the MT can process high temperature polymers which are ideal for autoclave capable tooling or compression molds for thermoset materials.

Things to Consider

With the addition of the MT, selecting the best size and configuration for an LSAM may not be quite as straightforward as it first appears. It depends on two major factors plus some additional considerations. The major factors are the material being printed and the size of the parts needed. Of these two, the material being printed is the most significant.

For purposes of machine selection, reinforced thermoplastic composite materials for room temperature or low temperature applications such as foundry patterns, boat plugs, boat and yacht molds, building structures and the like can generally be bonded securely with a variety of industrial adhesives. For these type of parts, even for really large parts, the smaller less expensive machine may be a better choice. The part can be separated into sections which can be printed individually and bonded into the final, potentially extremely large structure.

Although it seems counter-intuitive, this approach can be faster than printing the large structure as a single piece on a larger, more expensive machine. To better understand this we turn to the basics of the print process. Additive manufactured parts are printed in layers. The speed at which a layer can be printed depends primarily on how long it takes for the polymer being printed to cool enough to support the next layer. This layer cooling time depends on the polymer and is not affected by the size of the part. Each layer of a particular polymer takes the same amount of time, regardless of how big it is.

LSAM print heads can print faster, sometimes significantly faster than needed for most parts. Often it can print two three or more parts in the cooling time required for each layer. The large machine is only printing a single part, one layer at a time, making it two or three time slower. To print the part in one piece, the large machine must operate continuously, around the clock, sometimes for days.  This is not a problem for factories that operate on all three shifts but can present staffing problems for single shift operations. With the MT, several different segments of the same part can often be printed in a single shift. Depending on the item being printed, it is possible to print as much in a single shift as the large machine, printing a single part, can do in 24 hours.

For large parts made from bondable materials, often the smaller, less expensive machine is a better choice.

Materials intended for high temperature applications, PSU, PESU, PEI, Ultem, etc. generally are resistant enough to solvents that they can’t be effectively bonded. Even if they could, few if any, adhesives exist that can withstand the operating temperature or the thermal cycling these materials experience. For these applications, the machine needs to be large enough to print the part in one piece, even though it could be slower. This is where larger machine configurations are needed. The larger machines also offer the ability to print and trim at the same time, which may be beneficial in some circumstances.

Since the print heads are the same on all Thermwood LSAMs, the smaller MT can be used for these high temperature parts, provided they fit in the available envelope.

Just like the standard LSAMs, the MT comes complete, fully engineered with everything needed for production operation.
