Thermwood Releases 60-mm Melt Core for Higher Print Rates

Thermwood’s 60-mm melt core can 3D print layers with 250 ft. or longer bead length with most polymers, opening possibilities for the print process because of higher output capability.

Thermwood’s 60-mm melt core can 3D print layers 250 ft. or longer with most polymers, enabling a higher output capability for the print process. The 60-mm melt core, tested with different polymers, has achieved print rates from 480 to 570 lbs/hr., which translates to more than 100 ft. of bead per minute, almost double that of a standard 40-mm melt core, according to the company.

With Thermwood’s room temperature “continuous cooling” print process, the cycle time for each layer is determined solely by how long it takes a particular printed polymer to cool to the proper temperature to accept the next layer. Only by printing when the previous layer is within the proper temperature range can operators achieve a solid, void-free printed structure that maintains vacuum in an autoclave without a secondary coating. The print-head output then determines how much material can be printed during the time it takes for the layer to cool. The high print rate of the new melt core, even when processing high-temperature materials, along with Thermwood’s Vertical Layer Printing method, enable the print bead to be oriented along the length of the tool, even for tools that are as long as the machine table itself.


  • Why Robots and Additive Manufacturing Go Together

    3D printing and robots enable one another. We miss the possibilities of one if we do not consider the other. The combination includes AM for end effectors, robots for 3D printing parts, and different modes of metal and plastic production.

  • Wire Arc Additive Manufacturing Delivers Low Buy-To-Fly Ratios

    Manufacturers in the aerospace industry buy expensive raw material with one common goal: to make it fly. To reduce its buy-to-fly ratio (the ratio of material inputs to final part output), this company turned to wire arc additive manufacturing to create near-net shape parts.

  • High-Frequency Production

    The additive process that grew out of ultrasonic welding provides an efficient way to produce complex work, including parts with embedded components and even parts made from dissimilar metals.
