Thermwood expands LSAM product line yet again
Published on : Tuesday, May 4, 2021
Thermwood Corporation, manufacturer of the highly successful LSAM large scale thermoplastic composite additive systems, has announced the availability of even larger size machines than we currently offer.
The LSAM additive manufacturing system line is already the broadest in the industry with additive printers from a 5×5 foot table to large dual gantry print and trim systems up to 10×40 foot. Machines longer than 40 foot are available, but several 10×40 systems are the largest built to date.
With this new announcement, the large dual gantry print and trim machines are now available in a 15 foot width in addition to the current 10 foot width tables. As with the ten foot wide tables, the new fifteen foot wide table machines are available in lengths from twenty foot on, in ten foot increments.
New Heavier Gantry Design
The new machines utilize the new wide gantry design that was first developed for Thermwood’s LSAM 1010. The LSAM 1010 has both a print head and a trim head mounted on the same gantry, hence the need for a wide gantry even though the table is only 10×10 foot. The dual head combination on the 1010 weighs over 7,000 pounds, requiring a significant engineered gantry structure.
The smallest table length available in the fifteen foot width LSAM is twenty foot, however, because of the modular design of the table and support walls, this length can be increased by ten foot increments. The most popular table lengths to date for the ten foot wide table LSAM machines have been twenty foot and forty foot.
The new machines are equipped with the large LSAM print head structure which can be equipped with either the 40mm or 60mm print core. The 40mm core can print most polymers at about 200 pounds per hour while the 60mm core can print at over 500 pounds per hour. They can also be equipped with Thermwood’s patented Vertical Layer Print system, which makes it technically possible to print parts up to fifteen foot wide and as tall as the length of the table.
The new machines are equipped with all the advanced features of the entire LSAM line including the thermal sensor layer automation system which automatically controls bead temperature at layer fusion producing virtually perfect bonding between layers.
Thermwood offers three print head options on various machines with maximum print rates of 100, 200 and over 500 pounds per hour. Although many believe that print rate determines how fast a layer can be printed, it is actually polymer cooling that determines how much time is needed between layers.
Print head output then determines how much bead can be printed in that time and thus how large a part that can be printed by that print head using that polymer. The Thermwood LSAM 60mm print head with 500 pound per hour maximum print rate can print the largest part layers possible today.
With the introduction of the smaller LSAM Additive Printers plus these new wide table flagship LSAMs, Thermwood’s large scale additive manufacturing product line is, by far, the broadest available anywhere, with LSAM models from 5×5 foot to these new fifteen foot wide flagship models.
