About the LSAM Additive Printer

The LSAM Additive Printer systems are single gantry, moving table configurations and are available in two table sizes, 5โ€™x5โ€™ and 5โ€™x10โ€™. The 5โ€™x10โ€™ table is available in two configurations, 5โ€™ wide with 10โ€™ of front to back motion and 10โ€™ wide with 5โ€™ 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 โ€œsweetenโ€ the air.

LSAM additive Printers use the exact same print head mechanism as all the other, 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 donโ€™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.

ABOUT THE LSAM ADDITIVE PRINTER

HubSpot Video

 

Thermwood Corporation, manufacturer of some of the largest composite thermoplastic additive manufacturing systems operating in industry today, has announced the availability of a new line of lower cost โ€œprint onlyโ€ LSAM systems, called LSAM Additive Printers.

Thermwoodโ€™s current LSAM line of large scale, dual gantry, โ€œprint and trimโ€, near-net-shape additive manufacturing systems use an advanced print technology that produces high quality, fully fused products from a wide variety of reinforced composite thermoplastic polymers, including materials that process at high temperature like PSU, PESU, and PEI.

These systems are being used primarily to produce molds and tooling, most for aerospace and industrial production applications.

SMALL BUT POWERFUL

NEW 30MM PRINT HEAD

To accommodate the request for a lower cost system, Thermwood refined and updated the gantry structure of its highly successful 5 axis CNC routers.  This machine was re-engineered to use the incredibly strong โ€œslot and tabโ€ structural steel approach used on flagship LSAM machines. The same table, base structure and servo drives used on their five axis CNC routers could be used pretty much as is. With these changes the โ€œLSAM Additive Printerโ€ was born.

Although smaller than the flagship systems, it is capable of producing large parts at temperatures up to 450ยฐ C, with overall size limited primarily by the table size and working envelope. 

Available Sizes

The new LSAM Additive Printers are all fixed gantry, moving table designs with table sizes of 5โ€™x5โ€™ and 5โ€™x10โ€™ and are capable of printing parts up to 4โ€™ high.  The 5โ€™x10โ€™ machines are available in two styles, 5โ€™ wide with 10โ€™ of front to back motion or 10โ€™ wide with 5โ€™ of front to back motion. Maximum table print weight is 1,000 pounds, however, the 10โ€™ wide 5โ€™ deep machine is available with a dual servo drive which doubles the weight carrying capability. It is planned to equip the 5โ€™ wide 10โ€™ deep version with a Vertical Layer Printing option which will allow it to vertically print parts up to ten feet tall.

Trimming Printed Parts

For trimming printed parts, Thermwood recommends our new LSAM Additive Trimmer, which is available in the same table sizes as these new LSAM Additive Printers.  It is available with up to 5โ€™ of vertical travel, allowing it to trim completely around and over the top of the largest part the LSAM Additive Printer can print. As an added benefit, with both an LSAM Additive Printer and an LSAM Additive Trimmer, you can print and trim at the same time.

Although having a new LSAM Additive Printer plus an LSAM Additive Trimmer requires purchasing two machines, the combined cost of both is just over a third of the cost of an LSAM 1020 (which is currently the smallest flagship LSAM system that can both print and trim at the same time). The LSAM 1020 does have a much larger table, faster print head and the ability to do vertical layer printing up to 20 feet long, however, if you donโ€™t need those capabilities, the new LSAM Additive Printers may be an answer. If you already have trim capability, the cost can be even lower.

Same Powerful Features

The same powerful, feature rich LSAM control used on the large flagship LSAM systems, along with all its unique patented additive print features is standard on the new LSAM Additive Printers. A system for drying and conveying pelletized polymer material is also included as is a liquid chilling system to maintain temperature control on vital systems. This is especially important when processing high temperature materials.

Optional Enclosure

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

Optional Dual Hopper Dryer

The machine comes standard with a single hopper material dryer, however, an optional dual hopper dryer is also available for applications that change materials often.

Thermal Sensor Layer Automation System

Thermwoodโ€™s new Thermal Sensor Layer Automation System is also available on the LSAM Additive Printers. This is an exciting new system that automates the print process to easily and automatically obtain the highest quality layer to layer fusion.

Thermal Sensor Layer Automation System

With this system, a servo controlled thermal sensor, which travels with and rotates around the print nozzle, measures the temperature of the bead an instant before a new bead is added. This data is sent to the control which automatically adjusts print speed to print at the precise temperature that results in the best bead fusion for that particular polymer. Thermwoodโ€™s

LSAM print technology already produces the best quality, strongest large scale additive parts and this system not only makes it better but also easier.

Same Powerful Print 3D Slicing Software

The same Thermwood LSAM Print 3D slicing software used on all the other LSAM systems is used to program LSAM Additive Printers. Several levels of software training are available.

The Bottom Line

This new LSAM Additive Printer is intended to introduce LSAM additive technology to a whole new level of application and customer. It targets companies that want to print top quality, large composite thermoplastic parts, but donโ€™t really need, nor can they cost-justify, the really large LSAM systems. These new systems also target companies who already have sufficient trimming capability and may only need a quality print function. Applications include industrial fixtures, molds (including high temperature molds), tooling, foundry patterns, and hundreds, if not thousands of similar applications.

With the addition of the LSAM Additive Printers, Thermwood now offers the largest selection of large scale additive manufacturing systems for thermoplastic composite materials in the industry with models available for just about every application and budget.

 LSAM Research Lab at Purdue Enables CERN Particle Collider Upgrade Prototyping

Posted by Duane Marrett on Tue, Apr 12, 2022

Tags: Thermwood, Announcements, Purdue, Thermwood LSAM, Thermwood LSAM Research Laboratory

Purdue CMSC, in collaboration with Purdue Silicon Detector Laboratory (PSDL), is designing, prototyping, testing, and fabricating composite support structures for CERNโ€™s Large Hadron Collider (LHC) CMS and ATLAS experiments. This is part of the particle colliderโ€™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.

Finished result!
