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.

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.

The large demonstration part printed at the open house is one of twenty similar parts which when combined become a production mold for a large yacht hull

The LSAM MT is the ideal additive machine for a variety of exciting new applications

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.

Thermwood offers a full line of LSAM sizes to fit almost any application

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. 

About Thermwood Corporation

Thermwood is a US based, multinational, diversified CNC machinery manufacturer that markets its products and services through offices in 11 countries. Thermwood is the oldest manufacturer of highly flexible 3 & 5 axis high-speed machining centers known as CNC routers.

Thermwood has also become the technology and market leader in large scale additive manufacturing systems for thermoplastic composite molds, tooling, patterns and parts with its line of LSAM (Large Scale Additive Manufacturing) machines that both 3D print and trim on the same machine. These are some of the largest and most capable additive manufacturing systems ever produced and are marketed to major companies in the aerospace, marine, automotive and foundry industries as well as military, government and defense contractors.

Thermwood and Purdue’s Composite Manufacturing & Simulation Center have been working together to develop and test methods of using 3D printed composite molds for the compression molding of thermoset parts. They have just announced that they have successfully been able to compression mold test parts using 3D printed composite tooling.

The test part, a half scale thrust reverser blocker door for a jet engine, was designed at Purdue and is approximately 10x13x2 inch in size. The two-part matched compression mold for the part was 3D printed using Techmer PM 25% carbon fiber reinforced PESU at Thermwood, using its LSAM large scale additive manufacturing system.

The mold halves were then machined to final size and shape on the same system. The completed tool was next taken to Purdue’s Composite Manufacturing & Simulation Center, in West Lafayette Indiana, where it was mounted to their 250 ton compression press. Parts were then molded from Dow’s new Vorafuse prepreg platelet material system with over 50% carbon fiber volume fraction.

The Details

Both halves of the mold were printed at the same time during a single 2 hour and 34 minute print cycle. When using Thermwood’s “continuous cooling” print process, the polymer cooling determines the cycle time for each layer, allowing both halves to be printed in the same time it would take to print one half (since both parts could be printed in the layer cooling time available).

Both halves of the mold were printed in less than 3 hours

Machining, however, must be done in the traditional manner, one part at a time, although there is an advantage to machining printed parts. Since the part is printed to near net shape, the overall amount of material that must be removed is significantly less than if the tool was machined from a solid block. Machining of the two mold halves required an additional 27 hours.

The first attempt at compression molding was not successful, but techniques were developed to account for the mechanical and thermal conductivity characteristics of the polymer print material and a second attempt produced acceptable parts.

The team determined that using printed composite molds in a compression press does require a significantly different approach than a tool for the same part machined from a block of metal. First, the tool must be internally heated since the polymer composite doesn’t transmit heat as well as metal. Thermwood developed a technique for deep hole boring of the printed composite part using the trim head on its LSAM machine, allowing the deep insertion of cartridge heaters.

A special heat control allows the temperature of various areas of the tool to be controlled independently, helping address the challenge of balancing the thermal characteristics of the thermoplastic composite mold with the processing temperature requirements of the thermoset material being processed.

Printed polymer composite mold must be heated and reinforced

Printed polymer composite mold must be heated and reinforced

Also, the outside of the mold must be reinforced so that the composite polymer used for the mold itself is under only compression loads and not tension during the molding operation, since forces developed during molding are greater than the tensile strength of the composite polymers used for the mold. This approach has successfully withstood molding pressure of 1,500 PSI during initial testing and the team believes even higher pressures are possible.

Final Thoughts

Both Thermwood and Purdue believe this is an important first step in bringing additive manufacturing to compression molding. The speed and relatively low cost of printed compression tools has the potential to significantly modify current industry practices. Printed tools are ideal for prototyping and can potentially avoid problems with long lead time, expensive production tools by validating the design before a final version is built.

Additional development effort will be needed to further refine tool design and broaden the range of parts that this process will support, but all parties involved believe that this project demonstrates the viability of the basic approach.

Potential applications in the auto industry include prototyping and production tool verification. Because of high volume requirements for auto production, it is unlikely that these tools would function adequately for full production use, but actual useful production life is still unknown. It will require additional testing to determine just how many parts can be molded from an additive manufactured compression mold and what the ultimate failure mode actually is.

In aerospace, parts tend to be much larger and production volumes much lower, so it is possible that printed compression molds could find actual production use for larger, lower volume aerospace components, perhaps replacing open face tools and autoclaves for certain parts.

The relatively low cost and fast build rate of these additive molds significantly alters the decision matrix and timeline for developing new products using compression molding.

What Some of Our Cut Center Owners Are Saying...

The United States Air Force Research Laboratory (AFRL) Manufacturing and Industrial Technology Division (ManTech) is interested in large scale polymer-based additively manufactured (AM) composite cure tooling. Boeing submitted an idea to ManTech’s Open BAA to evaluate the current state of additive manufacturing technology with respect to the fabrication of low cost autoclave capable tools for the production of composite aerospace components. The initial demo tool is for an AFRL concept aircraft fuselage skin (Figure 1). Boeing contracted Thermwood to demonstrate capability of their Large Scale Additive Manufacturing (LSAM) machine.

The Thermwood LSAM machine offers an innovative additive manufacturing machine capability with its Vertical Layer Printing (VLP). The vertical layer printing AM process provides a significant cost benefit by increasing the size components can be printed, thus reducing assembly cost for large tools. To validate the VLP process using high temperature autoclave-capable materials, Boeing and AFRL chose to 3D print a section of the large tool to evaluate the LSAM functionality. The Mid-Scale tool was printed on Thermwood’s LSAM  Additive Manufacturing Demonstration machine in Southern Indiana using a 40mm print core running 25% carbon fiber reinforced Polyethersulfone (PESU).
