NASA Robots Use Additive Manufactured Parts In Space

Posted on: April 18th, 2019 by The Technology House

Thanks to the team at NASA Johnson Space Center and the Seeker Program, led by lead engineer Christopher Radke, we will finally see additive manufactured parts flying in space on the free flying autonomous robots Seeker and Kenobi. The Seeker program will test the robotic free flying robots that will fly in space around spacecrafts to monitor and inspect the ship. The SEEKER project has the first certified plastic AM parts in actual space. Both the Seeker robots will have Additive Manufactured parts made by TTH with the Carbon DLS (Digital Light Synthesis) to  process on M2 machines in CE 221 Cyanate Ester material.


There are four components that were 3D printed in Carbon’s DLS technology at TTH. These components are part of the cold-gas propulsion system used to thrust Seeker and Kenobi in space to navigate and inspect spacecraft. All parts could only be made with 3D printing in order to allow the  internal channels to work most optimally, while reducing weight and area in the assembly. The CE 221 material permits the parts to be used in space due to the strength, accuracy and temperature allowances. The internal channels were critical to produce parts with high accuracy to ensure thrust and flight was streamlined with design that could not be made any other way.


These Seeker robots launched to the International Space Station on Northrup Grummen’s Cygnus 11 from Wallops Island, Virginia on Wednesday April 17th at 4:46pm.

3D Scale Models

Posted on: December 18th, 2018 by The Technology House

Display Models

TTH applies many of the same engineering, design, model-making, and production skills we use in creating detailed prototypes to producing a growing line of scale models of aircraft and sea-going vessels and display items. They’re popular choices as retirement mementos and collectors’ items, for home and office décor, and as versatile show models, sales tools, and new concept displays in the boating and defense industries.

Cast Pewter Models

Artisans have used pewter, a tin-copper alloy, for millennia to create both decorative and utilitarian objects. Its soft, malleable nature makes it a natural for creating detailed, highly accurate models of ships, aircraft, buildings, etc. We cast a wide range of models and display items in high quality, lead-free pewter, creating all designs, master models, and tooling in house. The spin-casting process we employ allows us to create these pewter items quickly and efficiently.

We add new items to our cast pewter line frequently and we can create custom items to order, such as commemorative coins, plaques, or cast pewter coasters designed and finished with your company logo and colors for use as business gifts. We can also personalize your cast pewter objects with wooden bases and custom-engraved placards. Bulk discount rates are available for larger orders.

Architectural Models

In a competitive industry like architectural design, the success of a project sometimes depends on the ability to present a new concept to a client in a visually impactful way. Traditional model-makers can require weeks, even months, to create a detailed scale model, and the cost can be prohibitive. But it doesn’t have to be that way. Using the same high-speed stereolithography tools we use to create prototypes, Gear Precision Models can deliver a finished architectural model, ready for display, discussion, and redesign in as little as three days.

Our model design team will work with you throughout the process to ensure the finished model meets your needs without blowing your budget. Depending on the project, we can build models in a single piece or in sections, with removable roofs and floors, to show interior details. The high-resolution stereolithography process allows reproducing fine details like handrails and window trim accurately. If desired, pieces such as furniture, cabinets, and appliances, can be removable to allow greater design freedom. We can also finish models with a smooth surface or paint them to convey the proposed building concept.

How 3D Printing with Stereolithography is Helping Launch a new Surgical Navigation Technology

Posted on: August 14th, 2018 by The Technology House

Some of us learn by simply reading from a textbook, others learn by hearing directions aloud, but many of us learn from hands-on exposure to a task or concept presented to us.

The Technology House (TTH) teamed up with Cleveland-based medical start-up company Centerline Biomedical, Inc. to aid in their demonstration and explanation of their product and its value. Centerline Biomedical, Inc. is commercializing a novel surgical navigation technology aimed at vastly improving the precision, safety, and control in minimally invasive endovascular procedures.

Centerline Biomedical requirements:

  • Transparent model that allows surgeons to see tools in practice
  • Display movement of the apparatus going inside the aorta
  • Durable model to withstand multiple shipments and demonstrations
  • Create a high-quality, visually accurate model

Today, when a patient receives a stent or stent-graft, surgeons use X-ray fluoroscopy for navigation, which provides a poor form of visualization and subjects patients and caregivers to dangerous ionizing radiation. Centerline’s IOPS technology is designed to give surgeons high resolution color 3D imaging without using ionizing radiation.

Essential to the success of a young high-tech start-up is the ability to demonstrate the technology to potential investors, customers and other stakeholders, and Centerline looked to The Technology House to fulfill their need of a portable and rugged version of their technology and demonstration pieces. With their 22-year history in creating rapid prototype models for demonstrations, The Technology House was able to provide insight and information to Centerline Biomedical, Inc.

“The Technology House leveraged its rapid prototyping capabilities in Stereolithography to 3D print a vascular phantom and electronics housings exquisitely suited to our needs.”
– Vikash Goel, Chief Technology Officer

Centerline Biomedical envisions these demo prototypes eventually leading to product lines for training and educational use.

The Challenge: Create an Aesthetic, Durable Model in a Clear Paintable Material

After reviewing Centerline’s requirements and the 3D CAD file, one of our Project Managers met with our Additive Engineers and decided the best solution was to section the file to 3D print in the Stereolithography (SLA) technology of high resolution, accuracy, easy of finish, paint, and assembly.

Step 1: Section the File for 3D Printing in the SLA process

Using the Magics Software by Materialise, our Additive Engineers were able to bring in the provided 3D CAD file and make customized part breaks that allowed for the best parts to build, finish, paint and assemble.

3D CAD file sectioned via Magics

Step 2: 3D Print Parts in SLA ClearVue SL 7870

After sectioning the files, we were able to orientate and add supports as needed, which allowed us to layout the part perfectly on our 20’’ x 20’’ build platforms. Parts were then built by a UV laser tracing the part images layer by layer, or “slicing” the part at .005’’ increments, over and over until the build was complete. Parts were ready for the next steps in 1 business day.

Step 3: Prepare Parts for Paint

Once the parts finished printing, they went through a standard cleanup which includes: support removal, wash and UV oven cure. Parts are then lightly sanded to remove any support remnants and sand blasted. This is the standard SLA part finish. To prep a part for painting (or as we call it, a Paint Ready Finish), the parts are sanded to remove all the build layer lines. For the clear part, we wet sand the part because the clear shows imperfections such as scratches that then require post-paint buffing. From there any non-clear parts are primed and ready for paint.

Step 4: Paint Parts

For paint, we had three total parts. By painting the parts separately, it improved the overall process and look of the parts because we did not have to hand mask the model multiple times. If you have ever painted your home, you know this is the toughest and most tedious part of painting and it never comes out perfect the first time. The base was painted gray. The keypad was painted white. Both received a light texture to hide any small imperfections. The main aorta part needed to be painted clear with a red tint, not an easy task, but using our in-house custom color match system, we were able to customize a red tint clear paint. This allowed the parts to be red, but also see-through when used for demonstrations. After drying the aorta part was buffed and all parts were ready for next step.

Step 5: Assemble Parts

After all the parts were painted, the parts needed to be re-assembled together into a finished model. When sectioning the parts in the Magics software, we were able to add tolerance for the superglue leaving room for the parts to assemble perfectly without a big mess of excess glue.

Final Painted Aorta ModelFinal Painted Aorta Model

Step 6: Create Custom Reusable Shipping Package

The last step was to ensure the parts held up from demo to demo when shipped across the world. To do this, we used the CAD file to custom cut foam inserts that would fit into a box. This allowed ease of packaging and confidence that the part would show up perfect every time.

In the end, Centerline’s model is what we do at TTH every day. Our Project Managers and Engineering Team work together with customers to fully understand requirements of the project and even offer new solutions from our diverse in-house services, to exceed customer expectations.

Validated Injection Molding : Meeting Design Specs, Every Time

Posted on: April 19th, 2017 by The Technology House

When it comes to manufacturing parts, there are many methods to choose from. For example, injection molding is used to make everything from bottle caps to MRI coils. The process produces end-use ready results for applications in many industries. There are applications, such as medical devices or aerospace that require an even higher degree of accuracy and trust for a consistent, molded part. For these situations, Sea Air Space Machining and Molding (SAS) offers validated injection molding. Validation involves making sure that the machines used, materials employed, and manufacturing processes followed meet stringent accuracy and repeatability standards. While SAS offers a complimentary design review on all orders, validated injection molding involves far deeper design verification and customer collaboration. It starts with working closely with the customer to make a plan. SAS has a standard process and then tailors these steps to the customer’s unique needs. This collaborative process ensures that the standards SAS follows meet the customers’ expectations and requirements.

Communication is vital when making validated parts. Not only does SAS have regular contact with customers during the validation process for updates and progress, but they are also sure to immediately halt production and call the customer whenever SAS finds something that is not up to specifications.

Due to the cost and time overheads associated with validation, many manufacturers do not offer validated injection mold services, especially not on low volume orders. But, with the way SAS is setup, they are able to apply their skills and time to validate injection molding no matter the size of the order.

The Steps of Validated Injection Molding

Validation is a multi-step, detailed process. While there may be unique customer requirements, there are some steps that occur whenever a client requests validation.

Installation Qualification: Making Sure Everything Works

One of the ways validated injection molding differs from traditional processes is that it involves using IQ, or Installation Qualification. During IQ, the injection mold press equipment that will be used to manufacture a part is verified that it is installed correctly, working properly, and that the machine is receiving the proper power. This involves inspections from the manufacturer to make sure the equipment is set up correctly. The machines must be capable of repeatability and accuracy to meet all specifications.

Operational Qualification: Test, Test, and Test Again

After the IQ demonstrates that the equipment is correctly installed per manufacturer’s requirements, the next step of validation is to make sure the equipment is capable of performing over a specified range. This range is based on the material processing range and the processing parameters of the tooling and parts. This is called the Operational Qualification, or OQ phase. Here, data becomes especially important. An operator performs test runs, in which the operator records the machine’s operating settings by adjusting all manner of controls, including speed, pressure, temperature and more. Testers log, compile and store all data. This helps ensure the machines can operate over the processing range and notifies the operator if it falls out of the certain tolerances within that range.

Performance Qualification: The Real Thing This Time

Once OQ is complete, operators or technicians use the real manufacturing materials, while running the equipment through full cycles of parts. Basically, operators run the planned process for the part and verify that the process fits within the OQ range and the molded part meets all customer requirements. This is known as PQ, or Performance Qualification. During PQ, operators:

  • Record process parameters.
  • Ensure measurement accuracy for dimensional requirements.
  • Verify that materials behave as expected regarding durability and strength under various conditions.
  • Get customer approval that parts meet their specifications.

If PQ fails, it is back to OQ.

Lessons Learned

Formulating the validation process was a learning experience for SAS. Going through the validation process helped SAS to better plan out processes based on customer requirements and communicate the needs and importance to all levels of the organization. SAS now finds that it has less scrap when making any order, validated or not. Communication improved among all levels of employees. Learning that changing and updating processes is a good thing was something that became apparent to everyone. The importance of collecting and analyzing data, verifying processes and materials, and making sure everyone is clear on all steps became even more focused than it already had been.

Carbon 3D CLIP Material Spotlight: EPU Elastomeric Polyurethane

Posted on: October 25th, 2016 by The Technology House

Carbon 3D CLIP Technology

Carbon 3D Spotlight Material of the Week

Carbon 3D EPU Elastomeric Polyurethane

Highly elastic, resilient

Carbon 3D

EPU is a high performance polyurethane elastomer from the Carbon 3D Family. It exhibits excellent elastic behavior under cyclic tensile and compressive loads. EPU is useful for demanding applications where high elasticity, impact and tear resistance are needed such as cushioning, gaskets and seals.

Our Thoughts

1. Problem Solver

3D Printing Elastomeric parts has long been a pain point of many engineers. Very limited options exist. Polyjet can create a look and feel model but does not have the properties to withhold actual testing. The next option would be to create a RTV Mold and inject a low durometer urethane. This adds time and cost. Carbon 3D solves one of the biggest engineering pain points by being able to print high performing elastomeric materials. Gaskets, O Rings and Seals everywhere rejoice!

2. Material

The EPU is a high performance polyurethane elastomer from the Carbon 3D Family. The material behaves similarly to injection-molded elastomers, exhibiting elastic behavior over a wide temperature range. It has excellent tear strength, compressive strength and elasticity. The material can fit into any production application where a molded elastomer would have been used.

3. Durability

This video demonstrates the tear strength, compressive strength, and elasticity of EPU. A mesh structure is twisted, pulled, and repeatedly crushed by a push roller. This showcases EPU’s spring-like properties as it compresses under load and recovers quickly without deformation or abrasion.
