A cooperative effort between Thermwood Corporation, Applied Composite Engineering (ACE), Techmer PM and Purdue University’s Composites Manufacturing and Simulation Center has produced a composite helicopter part using a 3D Printed Polysulfone (PSU) mold.

The Details

The mold was printed from Techmer supplied carbon fiber reinforced material and trimmed on Thermwood’s Large Scale Additive Manufacturing (LSAM®) machine. ACE produced a production part from the tool in an autoclave using normal production processes.

Despite the fact that Polysulfone appears to be an ideal material for this application, the participants believe this is the first time PSU has been 3D printed, since it processes at temperatures and requires torque levels above those needed for normal polymer extrusion.  The extruder and print head on Thermwood's LSAM machine has been specially designed for ultra-high temperature, high-torque operation.

The part, an oil drip pan for a Chinook Helicopter, was molded in an autoclave at 275oF and 90 PSI. The printed mold held vacuum without the need for special coatings other than normal mold prep and release. With a Tg (glass transition temperature) of 372oF the participants believe that this particular PSU formulation may be able to process parts at up to 350oF which is adequate for about 95% of composite parts processed today. Additional tests will be performed to determine the suitability and durability of this material at this temperature. They also plan to evaluate Polyethersulfone (PES) which processes and operates at even higher temperatures.

The PSU mold and resulting part were displayed at the recent AM2017 Additive Manufacturing Conference in Knoxville.

Comparison vs Traditional Methods

Another interesting aspect of this collaborative effort is that a mold for the same part was built by ACE using traditional methods and the cost and build time was compared to making the same tool using additive manufacturing. The results were stunning.

The Results

Additive manufacturing material cost was 34% less and it required 69% fewer labor hours. Build time for the additive tool was 3 days versus 8 days for the conventional tool. If the part was larger, a support structure would be needed for the conventional tool which would add two days and more labor hours to the conventional process. A larger additive tool would not require a support structure.

The goal of this collaborative effort is to develop materials and processes to efficiently and reliably 3D print production composite tooling, capable of operating at elevated temperatures in an autoclave. These first successful results may indicate that they are very near reaching that goal.

Additive Manufacturing Becoming a Disruptive Force in Marine Tooling

Posted by Duane Marrett on Tue, Oct 17, 2017

Tags: Thermwood, Announcements, Additive, LSAM, Additive Manufacturing, Marine Tooling, Boat Hull, Pattern

A 3D printed boat hull pattern, from which fiberglass boat hull molds are made, has been completed using a near net shape additive manufacturing process and then successfully used to produce a production capable fiberglass mold in a proof of concept joint evaluation program. The completed pattern was recently displayed at the AM2017 Additive Manufacturing Conference in Knoxville, Tennessee.

A Collaborative Effort

This achievement was the result of a collaborative effort between Thermwood Corporation,Techmer PM and Marine Concepts. The tool was printed slightly oversized and then trimmed to final net size and shape using a Thermwood’s large scale additive manufacturing (LSAM®) system.

It was made from Techmer’s Electrafil© ABS LT1 3DP, which has proven ideal for marine tooling applications when processed using LSAM print technology. The entire print, assembly and trim process required less than ten working days to complete. After the printed and trimmed tool was coated and finished, a fiberglass mold was produced using the printed pattern. This effort clearly demonstrates the feasibility, practicality, economics and advantages of using additive manufacturing in the production of boat tooling.

The Details

The final tool was printed in six sections, four major center sections with walls approximately an inch and a half thick and a solid printed transom and bow, which were pinned and bonded together using Lord plural component urethane adhesive before being machined as a single piece on the Thermwood system.

Thermwood’s demonstration machine, used for this program, has a 10 foot by 20 foot worktable and features both print and trim capability on the same machine. The print head used for this project can print at rates approaching 200 pounds an hour when running this particular Techmer material. Thermwood also offers larger machines and higher throughput print heads as part of its LSAM product line. LSAM 10'x20' Machine Shown

Additive Manufacturing Could Change Marine Tooling Process

Additive manufacturing offers the promise of even more advances in marine tooling such as printing the hull and deck pattern as a single piece, allowing a production mold to be taken from the hull and then flipping the pattern over and taking a deck mold from the other side of the same pattern. All of these possibilities result in dramatically lower tooling cost and substantially faster build time. 

For large boats and yachts, Thermwood is evaluating the feasibility of printing molds directly, rather than printing a pattern from which the mold is taken. Because of their large size, these tools will need to be printed and machined in sections, even with very large LSAM® printers. It may also be possible to print integrated cooling channels for air or liquid into these large tools as part of the print process. 

With this initial success and some radical new ideas that appear to be possible with current materials and technology, it is becoming apparent that additive manufacturing may very well represent a disruptive force for the marine tooling industry.

Thermwood 3D Printed PPS Test Panel Maintains Vacuum Without Coatings

Posted by Duane Marrett on Wed, Jun 14, 2017

Thermwood has taken a major step toward its goal of 3D printing autoclave capable tooling from high temperature carbon fiber filled thermoplastic materials.

As an added benefit, Thermwood believes it will soon produce molds and tooling that function properly under vacuum in a heated, pressurized autoclave without the use of any type of coating to seal the printed tools. 

50% Carbon Fiber filled PPS Panels Tested by Fleet Readiness Center

50% Carbon Fiber Filled PPS Panel Printed and Machined on LSAM

50% Carbon Fiber Filled PPS Panel Printed and Machined on LSAM

Working toward this goal, Thermwood engineers have printed 50% Carbon Fiber filled PPS panels on its LSAM additive manufacturing machine that held vacuum to an industry acceptable level in independent testing. The test was conducted by the Fleet Readiness Center, FRC-East, located at MCAS Cherry Point, NC under a previously announced Cooperative Research and Development Agreement (CRADA) partnership, and the results met FRC-East acceptance criterion that the bag must not lose more than 2 in Hg over 5 minutes.

Previously, other unaffiliated companies have tested actual tools printed by Thermwood from 20% Carbon Fiber filled ABS and have also found that those tools held vacuum to an acceptable level without the use of any sealer or coating; however, the ABS material is not suitable for high temperature applications.

Despite that, several parts have been made from those tools under vacuum at room temperature and at slightly elevated temperatures. Thermwood has also already printed a 50% Carbon Fiber filled three dimensional PPS mold which has not yet been tested. Thermwood’s goal is to produce molds that will be used in a production autoclave, molding finished parts suitable for actual end use. 

Thermwood's Additive Printing Process 

Thermwood’s additive printing process differs fundamentally from conventional Fused Deposition Modeling (FDM) printing. Most FDM processes print parts by melting and extruding a relatively small bead of thermoplastic material onto a heated build platin that is contained within a heated chamber. The heated chamber keeps the extruded material from cooling too much before the next layer is added.

Thermwood machines print a large bead at such a high rate that a heated environment is not needed. It is basically an exercise in controlled cooling. Print speed is adjusted so that each layer cools to the proper temperature just as the next layer starts to print resulting in a continuous printing process that produces high quality parts. Thermwood believes this fundamentally different approach produces superior parts. 

Thermwood's Patent Pending Compression Roller 

Thermwood Patent Pending Compression Roller

One other feature that Thermwood engineers believe helps produce solid, void free parts, is a patent pending compression roller that follows directly behind the print nozzle, flattening the bead while fusing it tightly to the previous layer.
