TAHOE Boats, Springfield, MO. formally announced the all-new, revolutionary T16 boat design, engineered with families in mind. Using innovative technology, the T16 delivers an unprecedented lightweight design and affordability with an uncompromising commitment to quality and performance.

One factor that made this boat possible is that the T16 was designed and built in the U.S. leveraging innovative Thermwood LSAM techniques never before used in the marine industry.

White River Marine Group, the marine manufacturing arm of Bass Pro Shops, worked with Thermwood, utilizing Thermwood’s Large Scale Additive Manufacturing (LSAM) system and the latest in LSAM technology to custom-print the tool used to manufacture the boat’s hull – the first time 3D printing has been used on actual boat production at this scale.

This boat-building advancement led to greater efficiency in the planning, design and construction of the T16.

The Process

Thermwood printed the master pattern for the boat hull at its Development/Demonstration Labs is Dale, Indiana. The pattern was printed in six sections from 20% carbon fiber filled ABS supplied by Techmer PM, who was an active partner in the program. The joints between the pieces were machined, pinned and bonded together and the assembled hull machined to final size and shape. The entire process required only ten days to complete.

After printing and machining, the tool was sent to White River, where they applied, sanded and polished a proprietary coating, which they developed earlier, using previously printed parts supplied by Thermwood.

Prior to this public introduction, Thermwood was able to use images and videos of the process, which have been on our web site for some time now, however, we respected a request not to disclose the participants or final use of the tool until the boat was publicly released by White River Marine Group.

Current Technology Speeds The Process Up Even More

An interesting note is that this type of tool can be produced in even less time with current technology. Using Thermwood’s Vertical Layer Printing (which wasn’t available at the time this tool was made), this type of pattern can now be printed as one piece in just over two days, eliminating the machining between sections and the bonding process. This should cut build time almost in half.

Master patterns, such as this, are used to make molds for high production rates where multiple molds are required. For larger boats or lower production rates, it may be possible to print the mold itself rather than a pattern from which multiple molds are made. Thermwood has also been working on this approach and has recently announced the successful production of a seven foot long, 1/7 scale model of a yacht hull mold using Vertical Layer Printing. Work continues in both these areas.

Even at this early stage of development it is apparent that large scale additive manufacturing could have a dramatic, perhaps even a transformational impact on production methods used in the marine industry, significantly reducing tooling cost and dramatically speeding up the tool building process.

Thermwood has completed initial testing of a larger melt core for its LSAM (Large Scale Additive Manufacturing) systems and the results are stunning.

Print up to 570 pounds per hour

Thermwood’s additive print head housing can accommodate interchangeable melt cores.  A melt core consists of a feed housing, extruder and polymer melt pump and determines just how fast material can be printed.

The standard 40mm melt core has a maximum output of between 190 and 210 pounds per hour, depending on the polymer being printed, which translates to 40 - 50 feet of standard bead (0.83”x0.20”) per minute.

The new 60mm melt core has been tested with different polymers and has achieved print rates from 480 to 570 pounds per hour, which translates to well over 100 feet of bead per minute.

More Info

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 previously printed layer is within the proper temperature range can you achieve a completely solid, void free printed structure that maintains vacuum in an autoclave without a secondary coating. This is as fast as you can print a layer.

The print head output then determines how much material can be printed during the time it takes for the layer to cool. Bigger print heads mean bigger parts not faster layer to layer print time.

“This new development opens a new world of additive manufacturing possibilities” says Thermwood’s Founder, Chairman and CEO, Ken Susnjara. “This is one of the most exciting advances we have achieved to date and now we can do things we couldn’t even consider before”.

New Possibilities

For example, Thermwood recently announced Vertical Layer Printing which allows parts to be printed that are as long as the machine table. In this process, however, the layer stack direction is along the length of the part. This works well for room temperature or low temperature patterns, fixtures and molds, however, for high temperature molds, for use in an autoclave for example, the thermal expansion (CTE) along the stack direction is as much as 20 times greater than along the bead direction. Therefore, it is desirable to print long tools with the bead oriented in the long direction, however, print heads, even Thermwood’s 200 pound per hour head, currently the largest in the industry, have been too slow for this…until now.

The high print rate of the new melt core, even when processing high temperature materials, allows the print bead to be oriented along the length of the tool, even for tools that are as long as the machine table itself.

Melt Core Changeover in One Shift

In addition to a maximum speed, each melt core has a minimum speed at which it can continuously print. Parts with bead lengths smaller than this minimum, require the print head to move to a “Hot Hold” area where it runs at a slow maintenance speed, spilling material at a slow rate until the required cooling time has been achieved. This wastes material and means the larger melt core may not be desirable for all applications. Many tools and molds are just too small for efficient printing with the larger core.

If a user needs both small and large parts on the same machine, the melt cores can be switched in less than a shift.

Final Thoughts

Thermwood believes the next step in this development is to address the challenge of really long autoclave capable tooling. Be assured, work in this area has already begun.

The Secret to LSAM Print Quality...A Different Process

Thermwood has already 3D printed a full size pattern which was used to produce production sport boat hull molds. Much larger vessels, yachts for example, require a different approach. In these instances, it is desirable to print the mold itself rather than print a plug or pattern from which a mold is made.

Working with an undisclosed marine industry collaborator, Thermwood has printed a scale model of such a hull mold to test and validate the process.

Video

Printing The Mold Itself - No Plug/Pattern Necessary

The 1/7^th scale test mold for this project is approximately seven feet long (the full size hull is approximately 50 foot). It was printed from 20% carbon fiber filled ABS using Thermwood’s LSAM additive manufacturing machine.

Six separate pieces of different lengths, the longest two, each being over seven feet long, were printed concurrently using LSAM’s Vertical Layer Print capability. Printing required about 30 1/2 hours.

The ability to simultaneously print multiple parts of variable heights highlights the flexibility of both the vertical print process as well as Thermwood’s LSAM Print^3D slicing software. The parts were then trimmed on the same machine and assembled into two mold halves.

More Details

The tool includes a deep undercut at the transom, so the finished mold needs to be two pieces, split down the middle. These mold halves are clamped together for layup and then separated to remove the finished hull after curing.

Molds for hulls of longer than fifty feet will be printed in multiple sections, assembled for hull layup and then disassembled to remove the finished part. The test tool printed here simulates that assembly and disassembly process.

The tool printed in this program will be tested using production materials in a production environment. Thermwood continues to work on methods and techniques needed to refine this into a production ready process.

Thermwood believes that the marine industry will benefit significantly from emerging large scale additive manufacturing technology and that this project is a significant first step toward the direct production of large vessel tooling.

Cut Ready - The First CNC That Doesn't Need a Programmer!

Cut Ready doesn’t need a programmer because there is already one inside the control. We call him “Artie”.

Despite the cute name, Artie is actually a cutting edge, artificial intelligence engine inside the Cut Ready control. You tell him what you want and he creates a program to make it. 

Artie has actually been hiding out behind the scenes in the Cut Ready control this whole time, but he has never made an appearance until now. He is the first A.I. dedicated to making your manufacturing life easier to handle.  While he is a CNC programmer and designer at heart, he also watches over your shoulder to make sure everything goes smoothly and efficiently. 

You tell him what you want and he creates a program to make it. Whether it is cabinets, doors, moldings or furniture, Artie will program it for you! 

These are not pre-programmed libraries. No part programs exist in the control until Artie creates them.  He is already capable of programming tens of millions of unique products and is constantly learning how to make and do more and more new things. Artie is easy enough that virtually anyone can work with him with little or no training. For more on Artie, click here.

Cut Ready is currently available on two machines from Thermwood:

 The Cut Center - requires neither a CNC programmer nor a trained machine operator. Artie moves beyond just programming to guide the operator through the entire production process real time. It is complete, fully contained with all the ancillary equipment smoothly integrated into a package that almost runs itself.  Pretty much anyone can run a Cut Center.

The Cut Ready 43 - is a lower priced machine that doesn’t need a CNC programmer but does require a trained and somewhat skilled machine operator.  With the Cut Ready 43 system, Artie offers help during the production process but not quite to the extent that it does with a Cut Center.  

More Info on the Cut Ready 43 with Artie Inside

The Cut Ready 43 is equipped with a 5 by 8 table, a 21-position tool changer and a high flow vacuum hold-down system (additional table sizes and options are available).

The Cut Ready 43 is intended to bring the magic of Artie to a lower priced system. It features a full-sized vacuum table and, just like its big brother, doesn’t require a CNC programmer. Just like a Cut Center, it can help you quickly and easily create most products a cabinet shop would want to make without a CNC programmer (only operational training is required).

Since this is a CNC router at its core, you are free to program and operate it as a normal CNC router if you want, but the magic of Artie makes the Cut Ready 43 a whole new exciting experience!

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

Thermwood Corporation has entered into a collaborative program with the Naval Surface Warfare Center, Carderock Division to explore the use of additive manufacturing technology in developing marine models for ship and ship systems testing.

Please click below for video 

The Details

Carderock Division is the U.S. Navy's state-of-the-art research, engineering, modeling and test center for ships and ship systems. It is the largest, most comprehensive establishment of its kind in the world, serving a dual role in support of both our U.S. naval forces and the maritime industry. 

Navy and maritime communities have come to depend on their expertise and innovative spirit in developing advanced platforms and systems, enhancing naval performance, reducing operating costs and addressing the Navy's evolving mission.    

This initial validation program was centered on printing an unclassified scale nose of a submarine using Thermwood’s LSAM additive manufacturing system. The part was printed using 20% carbon fiber filled ABS in 11 hours and 45 minutes using traditional horizontal layer printing and a 40mm melt core. Final trim required 5 hours. Both printing and trimming were completed on the same machine, using Thermwood’s 10’ x 20’ LSAM at its demonstration lab in Southern Indiana.

Because of layer cooling requirements, the print rate for this part was less than half of the maximum rate the machine is capable of. It is expected that, moving forward, this program will include the printing of additional components using both horizontal and vertical layer printing.

Thermwood has released a Vertical Layer Printing (VLP) option for its LSAM (Large Scale Additive Manufacturing) machines. This option allows parts to be printed which are as long as the machine table itself.

It does this by adding a second moving table, mounted perpendicular to the main fixed horizontal table. As layers are printed, this vertical table moves after each layer is printed, growing the part along the length of the machine rather than growing it upward. Thermwood’s “controlled cooling” print technology minimizes sag, which might otherwise pose a serious problem if the part were kept at an elevated temperature, as is common with traditional thermoplastic composite printing.

VLP Example Video

12 Foot Long ABS Trim Fixture for Boeing 777x Aircraft

As previously announced, one of the initial parts printed with this system is a 12 foot long, carbon fiber reinforced ABS trim fixture for use in the production of the Boeing 777X aircraft.

VLP More Info

During development, Thermwood has vertically printed and validated the use of a variety of polymers, including high temperature materials such as PSU, PESU and PEI with good results. It appears that parts printed using VLP are structurally and functionally identical to parts printed in the traditional horizontal layer orientation.

This means that, just as with traditional horizontally printed LSAM parts, molds and tools printed using VLP maintain vacuum in an autoclave to aerospace standards right from the machine, without the need for any type of external coating.

Versatile Vertical Layer Printing

During VLP printing, the growing part rides on Teflon coated stainless steel belts. The belts and table drives (which can be fitted to any LSAM that is at least 20 feet long), have been designed to process parts which weigh up to fifty thousand pounds. Thermwood believes that this is more than adequate for anything customers are considering today.

Print Long Parts in One Piece with VLP

The main advantage of Vertical Layer Printing is that long parts can be printed in one piece.

While it might be faster to print multiple sections of a large part simultaneously, they must then be bonded together so that they can be machined as a single piece. There are some disadvantages to this approach:

• It requires time, labor and effort to machine mating surfaces, glue them together and wait for the adhesive to completely cure.
• It may also require more than one bonding session for a larger part which typically requires more time and effort than simply printing the part in one piece.
• Also, gluing printed parts together generally only works for certain room temperature or low temperature polymers.
• Higher temperature materials are generally chemically and solvent resistant enough that they don’t bond well enough for autoclave use. This means if you want to 3D print a really large autoclave tool using a high temperature polymer, printing it in one piece is the only real option. Thermwood’s VLP now makes this both feasible and practical.

Quick Change from Horizontal to Vertical

VLP has been designed so that the machine can be reconfigured from standard horizontal layer printing to vertical layer printing or back again in a matter of a few hours. It is clear that technology exists, right now today, to 3D print large autoclave capable aerospace tooling on a production basis. Thermwood has already been granted patent protection on key aspects of its Vertical Layer Print technology.
