Carbon: The Ultimate Tool in the Additive Manufacturing Tool Belt

Posted on: December 12th, 2017 by Owen Timlin

Material Properties. Part Design. Part Finish. Economics. Lead Time. Pick Two.

That is how most projects go in Additive Manufacturing. It is very rare in the AM world where you can have your cake and eat it too. That is why the University of Adelaide Project is so special.

First Approach

Dr. Tommaso Watson’s Airlock started out as two CNC machined stainless steel parts soldered together. The stainless steel material allowed the part to be autoclavable which was a requirement. However this was expensive, time consuming and compromised the design.

Second Approach

Looking to improve upon the design, Dr. Tommaso Watson’s Airlock moved to Additive Manufacturing with Fused Deposition Modeling. The FDM ABS Airlock allowed for an optimized design and cut down the lead time. However it still was not cost effective at scale, the layer printing created porosity and the ABS material was not autoclavable.

Carbon Approach

Utilizing our Carbon technology, we were able to recommend a material that met all his criteria. Carbon prints isotropic parts which eliminated the porosity. Carbon’s CE 220 material is autoclavable. The lead time was cut down from one month to a week. The Carbon process produced parts at 67% the cost of the first two options.

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.

Carbon 3D CLIP Material Spotlight: RPU Rigid Polyurethane

Posted on: April 27th, 2016 by The Technology House

     Carbon CLIP 3D Printing

 

Carbon 3D Spotlight Material of the Week

RPU Rigid Polyurethane

Tough and abrasion resistant, stiff

 

Rigid Polyurethane Pedals

RPU is our stiffest and most versatile polyurethane-based resin out of the Carbon 3D family. It performs well under stress, combining strength, stiffness, and toughness. These properties make RPU particularly useful for consumer electronics, automotive, and industrial components, where excellent mechanical properties are needed.

Our Thoughts

1. Material

Every manufacturing process has its bread and butter material; 3D Printing has ABS, CNC Machining has Aluminum, Injection Molding has Polypropylene. Carbon 3D is no different. The RPU Rigid Polyurethane is our workhorse material. It builds fast, accurate and finishes great. Our team loves its. If our techs had it their way they’d build every part out of it.

2.Surface Finish

The RPU Rigid Polyurethane has the best surface resolution out of the all of the Carbon 3D materials. Period. The parts off the machine require little to none post finishing. When parts need to be finished, the material is extremely acceptable to sand blasting and paint.

3.Production Ready

Out of all the materials the RPU Rigid Polyurethane is the farthest along to start production today. The material has the versatility and mechanical properties to make it a great fit for housings, brackets, ducts, connectors, etc. We have already seen several cases where CLIP technology has already been a cost and time effective alternative to CNC Machined or Injection Molded parts.

Carbon CLIP: Design Without Restrictions

Posted on: March 2nd, 2016 by The Technology House

Last year Carbon burst onto the scene with their Continuous Liquid Interface Production (CLIP) 3D printing technology. We are part of a select group of companies who have been working with Carbon to push the boundaries of CLIP across various industries. And we could not be more excited about our new relationship with Carbon.  We recently spoke to one of our engineers, Pat Shevchek, who has been working tirelessly on CLIP on his thoughts about this ground breaking process.

What is your role?
I am a manufacturing engineer at TTH tasked with operating and integrating CLIP into our repertoire of production capabilities.

What is Carbon’s CLIP biggest impact in the additive manufacturing world?
There is a lot to this question. It gives us the ability to design and directly manufacture geometries that could not be produced using any traditional manufacturing method in the past. The speed, library of printable production materials, and quality of final parts are CLIP’s best advantages.

What industries can utilize CLIP?
The short answer is any and all. As more and more materials are developed there really is not a single industry that would not be able to utilize CLIP. There will certainly be niche markets early on but development will expand to all industries.

Where do you see CLIP going from here?
In the short term we currently have a limited build volume. I see this buildable volume as well as speed increasing. Long term, I see CLIP changing the way engineers design and the makeup of manufacturing as a whole.

3 Things about 3D Printing Bureaus You Should Know

Posted on: January 28th, 2016 by The Technology House

When you need to 3D print parts, you can either invest and utilize your own equipment, or order parts through a 3D printing bureau.  But, how do you know when it is best to leverage the 3D printing processes of a service provider compared to in-house capabilities?  Below are the top 3 reasons why customers have utilized a service bureau, like us.

3D Laser Printing

1.Expert Advice
Customers often come to us and say something like “We want the part to do this, but do not know what material or process will work best.” 3D Printing Service Bureaus have experienced project managers that can walk you through different processes and materials based on what you need for your design and project. They can offer the best options to get your part for your deadline whether it’s for a sales demo, marketing presentation or testing.

2. Less In-house Overhead
The costs involved with having your own machine can add up quickly. In addition to the cost of the equipment, there are also the costs of training/hiring employees, software upgrades, machine maintenance, and material & machine part purchases.  It may take years for a company to break even on their own machines.  This is why a lot of customers come to us.  They can simply send us the files to print to minimize risk and compensate for internal processes that don not exist.

3D Laser Printing Machines

3. Access to Advanced Materials and Processes
We have seen over the past few years that customers need prototypes to act as close as possible to the production piece.  This not only involves advanced materials, but also secondary processes like finish and paint.  Having both materials and processes under one roof allows one to efficiently stream line their timeline as well as utilize a “one stop shop” vendor.

But don’t take our word for it.  If you want to learn more about how a 3D Printing Service Bureau can help you, then feel free to contact us. Allow us to understand your concept and needs and champion it into actual parts by determining which of our processes will bring them to life in the most efficient way possible.

Can 3D Printing Show Realistic Details?

Posted on: December 14th, 2015 by The Technology House

One request we consistently hear is “How can you make my prototypes in color?”  or “How realistic can you make my parts look?” Previously most colors would be applied in paint as a secondary operation, or colors would be represented through photo renderings.

But now, TTH can 3D print parts in full color through  Color Jet 3D printing (CJP) . Realistic color models can be printed and delivered within days.  CJP through us will present your model in realistic colors.  The visualization of CJP will help you  gain attention and awareness in your model.

But don’t take our word for it, see for yourself:

SAE Racing Team Incorporates 3D Printing in Car Design

Posted on: November 30th, 2015 by The Technology House

This year, we are once again sponsoring the University of Akron’s SAE racing team.  We work with their team to 3D print and manufacture various parts that are used in the car.  We recently spoke with them to talk about this year’s plans and objectives.

20150801_12-19-34_8540_buck

Who is the team composed of?
Our team is composed of multiple tiers of members in a clever layout that allows for a system of checks and balances to ensure the quality of our design. In summary, this layout consists of two team captains who oversee both administrative and technical responsibilities. Beneath the team captains are our subsystem leaders, who oversee the design and production of different subsystems on the car, such as engine and suspension. Finally, we have general support, which is normally composed of newer members on the team. The general support members will help with all aspects of design and production of the car.

 

How many races do you plan to compete in this year?
Our team traditionally participates in multiple competitions around the world. Historically, this will include at least one competition in America, one in Canada, and one in Europe. This year, we plan on visiting Lincoln, Nebraska for our American competition, which will be followed by a competition in Germany. We also plan to end the season by going to Canada to participate in the Toronto Shootout.

 

What are your plans for this year’s car?
This year we plan to focus on improving the robustness of our design and looking into more advanced simulation/testing techniques to validate our designs before the ideas go into the production stage. This is an area where 3D printing can prove to be very useful with its rapid prototyping abilities. By improving our simulation/testing techniques we will be able to build a lighter car without sacrificing reliability.

 

How do you incorporate 3D printing in your design?
3D printing plays various roles in the design/production of our race car every year. 3D printed parts can serve roles that range from just testing fit and finish before actual production of the parts which involves lengthy machining processes, or they can even be finalized parts that will make their way on to the car.

 

What are the benefits you see by using 3D printing rather than traditional manufacturing methods?
One of the most useful attributes of 3D printing is that it allows us to produce complex geometries that would be next to impossible to machine from billet material. Some examples of these complex geometries include hollow parts, sharp corners, and small radii. By taking advantage of the benefits offered by 3D printing for production, we are able to build a lighter car without sacrificing our reliability.

Stay tuned, for we will write a follow up blog in May once their car is complete.  We wish them the best of luck, and look forward to working with them this year.  To learn more about their team, feel free to visit  their website.

What’s the Benefit of Metal-to-Plastic Conversion? Part II

Posted on: November 12th, 2015 by The Technology House

As the old saying goes, “It’s hard to teach an old dog new tricks”-Like converting metal parts to plastic.

We discussed in our last blog, when done properly, parts converted from metal-to-plastic benefit from:

-Cost reduction
-Improve functionality
-Design Freedom

But what industries benefit from metal-to-plastic part conversion? Three of the major industries we have helped are the automotive, aerospace, and medical industries.

The automotive and aerospace industries are converting parts to plastic in order to reduce vehicle weight, and to meet tougher federal emissions standards. The reason for the latter is that certain plastics are chemically and heat resistant.  These plastics can be utilized in the fuel and fluid handling systems.

A major reason we have seen the medical industry utilize metal-to-plastic conversion is for device ergonomics. Plastic products can be easier, such as molding a handle that is hard plastic, but the grip area is a soft rubber.  Another reason for metal-to-plastic conversion is that plastic has a lower thermal conductivity.  Therefore, plastic parts may not be cold to the touch, which allows the patient to be more comfortable when the product is in use.

We have helped a lot of customers over various industries with metal-to-plastic conversion. Contact us to consult with our team about the feasibility of converting your metal products to plastic.
