Thermwood expands LSAM product line again

Thermwood, a manufacturer of the LSAM large scale thermoplastic composite additive systems, has announced the availability of even larger size machines.

The LSAM additive manufacturing system line is already broad, with additive printers from a 5x5ft table to large dual gantry print and trim systems up to 10x40ft. Machines longer than 40ft are available, but several 10x40 systems are the largest built to date.

With this new announcement, the large dual gantry print and trim machines are now available in a 15ft width in addition to the current 10ft width tables. As with the 10ft wide tables, the new 15ft wide table machines are available in lengths from 20ft on, in 10ft increments.

New heavier gantry design

The new machines utilise 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 10x10ft. The dual head combination on the 1010 weighs over 7,000lb, requiring a significant engineered gantry structure.

The smallest table length available in the 15ft width LSAM is 20ft, however, because of the modular design of the table and support walls, this length can be increased by 10ft increments. The most popular table lengths to date for the 10ft wide table LSAM machines have been 20ft and 40ft.

40mm or 60mm print core available

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 200lb per hour while the 60mm core can print at over 500lb 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 15ft wide and as tall as the length of the table.

Same powerful features

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.

As the market becomes more comfortable with the capability and reliability of LSAM technology, the new sizes open interesting opportunities in areas where really, really large parts are needed.

Three print head options available

Thermwood offers three print head options on various machines with maximum print rates of 100, 200 and over 500lb 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 500lb per hour maximum print rate can print the largest part layers possible today.

Largest selection of large scale additive manufacturing systems

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 5x5ft to these new 15ft wide flagship models.
