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.

8 Questions to think about when choosing your Injection Mold Tooling

Posted on: September 13th, 2016 by Owen Timlin

Injection Molding is one of the most common ways to manufacture your product in production. The first step is choosing a tooling option that works for your project. Here are 8 questions from actual customers that will help make it a little easier to choose your Injection Mold Tooling.

Injection Mold Tooling

What is the scope of the project?

This is the probably the most important factor in determining which tooling method to use.

If the part is for pre-production then the answer is simple, aluminum tooling. This is common when the project requires the part to be made with the end production injection mold material. Aluminum tooling offers lower costs and faster lead times. If the material requirement is not needed see alternative options on RTV Molding and 3D Printing.

If the part is for production then there are a couple things to consider. What are the EAUs on the part? How long will the project run?

How does part size effect tooling?

Part size plays a big factor in determining tooling. Larger parts will need to be built in a standalone tool however smaller parts that fit within the size parameters may be subject to a (more efficient) cheaper alternative. Insert tools are extremely popular for smaller components. Instead of paying the full price of a standalone tool we can look to build an insert tool that fits into the (standard MUD) base unit on our press.

For example, you have a small housing that is 3″x 2″x 1/2″ and needs to be produced via Injection Molding. Instead of building a full standalone tool for such a small part we will build an insert tool out of aluminum or steel that fits into our pre-existing bases on our press. This is an extremely economical and waste minimization method to produce smaller components. We offer insert sizes ranging from a 5″x 5″ all the way up to a 11″x 14″.

How does part volumes effect tooling?

Part volumes can effect tooling especially when the volumes reach a higher level. The standard is a single cavity tool for low volumes of a couple hundred or a couple thousand parts per year, but as the part volumes grow you can look to add multiple cavities on the tool to produce parts more economically. When quantities and life of project are unknown or there is no solid forecast, single cavity tools are a good place to start. You can always look at building multi-cavity tools later on. Multiple cavity tools come with a little more upfront cost on the tool but it can significantly lower the piece price on your part.

Does part material effect tooling?

Yes, it does. The part material has direct effect on tooling for a couple of reasons. Mild injection mold resins like a Polypropylene are a lot easier on a mold therefore contributing to a longer tool life. Harsher injection mold resins like a Glass Filled Nylon wear down a tool much easier. This can be a crucial deciding factor when your part has a life of 8,000-12,000 pieces and you are deciding between aluminum or steel tooling.

Does part geometry effect tooling?

Yes, it does. We thoroughly evaluate each part before quoting. We look at part features that will effect the tool. Does it have undercuts? Cores? We also look at surface finish requirements. Will it be grained? Polished? Textured? These all effect the decision on the type of tooling used.

What is the life expectancy of a tool?

Aluminum tools are good for a lifespan of anywhere from 2,000- 10,000 parts depending on the type of aluminum used, part material and geometry.

Steel tools are good for a lifespan of 100,000 + parts depending on the material and geometry of the part. The tool may need re-worked after it has been in production for awhile.

What is the timeline to build a tool?

This changes on a part by part basis but a good rule of thumb would be:

Aluminum tools can be built in anywhere from 4-6 weeks for small parts and 6-10 weeks for larger parts while steel tools can be built in anywhere from 6-8 weeks for small parts and 8-12 weeks for larger parts.

What is the cost difference for Injection Mold Tooling?

This also changes on a part by part basis but typically a steel tool costs anywhere from 20-30% more then an aluminum tool.

The Future

Posted on: August 18th, 2016 by The Technology House

With The Technology House’s 20th anniversary this month, I have done much reflecting on how and why we got to this mark. If you ask someone that has worked with us, they will say that we do Rapid Prototyping, Additive Manufacturing, 3D printing, Injection Molding or CNC Machining. They will tell you the services we provide. While driving in to work today it hit me like a ton of bricks when I asked, “Why do we do what we do?” Yes, The Technology House can make parts but the reason we are here is bigger than that.

While working at a leading consumer goods company our owner Chip Gear began noticing thousands of dollars being spent on rapid prototypes from his engineering team. As he starting to dig into WHY they needed these parts, he found his answer. Time.

It saved them time. See, time is the one thing we can never replace or get back. You can rework a project or fix a tool, but you will never get the time spent on that back. He realized that this process was a disruptive technology, able to cut new product launches from years to months.

So, 20 years later, here we are. Still working every day to save people in this world time. Pushing the limits to reduce product launches from years to months to weeks.

There is a lot of hype and excitement in the 3D Printing industry today. Entrepreneurs like Chip are the reason this excitement can be found in classrooms, universities and companies worldwide.

Today, we celebrate Chip and his family. We celebrate all our customers, vendors, suppliers and especially the employees that helped to get us to where we are at today. And we celebrate The Future and all its unknowns. We will all keep pushing the boundaries of time with innovative design and technologies to help better the companies of the world and future.

With the utmost appreciation, we thank you! We would not be here today without all of you!

Manufacturing Exhibition at the Ohio Bioscience Expo & Showcase

Posted on: July 19th, 2016 by The Technology House

 

Next Wednesday, July 27th 2016, we will be exhibiting at the Ohio Bioscience Expo & Showcase in Columbus, OH. This event is part of the [M]EDNEXT series presented by MAGNET in partnership with BioOhio. The idea of this [M]EDNEXT series is to connect established manufacturing companies to critical biomedical resources to help create new revenue streams, create jobs and strengthen the economy here in Ohio. The Ohio Bioscience Expo & Showcase, in particular, was created to help local Ohio company’s like ours, find and connect more closely with local medical companies.

Ohio Bioscience Expo & showcase

BioOhio is a membership organization that builds and accelerates bioscience industry, research and education in Ohio. They have almost 400 members ranging from start-ups, universities, research institutions and medical manufacturers.

MAGNET is a networking, nonprofit organization to support, educate and champion manufacturing in Ohio. They are dedicated to help manufacturers grow and compete.

We (Sea Air Space Machining & Molding with The Technology House) decided to attend and exhibit this year at the BioOhio event because we see the growing need for medical companies to connect with local resources like us for engineering, design, prototyping, and production manufacturing. The medical industry is growing and is unique when compared to some other industries because of quality requirements, materials and, often times, low volume production required.

This creates a niche area for a company like ours that can provide Additive Manufacturing, Cast Urethane Molding, Custom Injection Molding and CNC Machining all under one roof. Many component manufacturers are setup to run high volume production with running the same part over and over. This can be different in the medical industry. Sometimes we may run two different parts on the same machine in the same day. But, the production parts still need to be turned around quickly, with high quality and a fair price.

This is why the Ohio Bioscience Expo & Showces is important and a great opportunity provided by BioOhio and MAGNET. This event will help to spread the word to both sides, in order to support, grow and better each other and the way our businesses operate. In this day and age, it is critical for manufacturing and medical companies alike to create networks in order to provide the most efficient part from the most efficient process.

With both The Technology House and Sea Air Space Machining & Molding, we have seen the needs from design to prototype to production. In the last couple years, we have also seen the need for specialized processes for the medical industry, like validated injection molding. Last year, we worked with another local medical company to help develop a validated injection molding process. Hopefully we can help more companies too.

We hope you come to visit us and all we can offer down at the Ohio Bioscience

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.

How Can You Save Money on Your Next Molding Project?

Posted on: February 24th, 2016 by The Technology House

Custom Mold for Injection Molding

When you are ready to move your product to production,
one of the last things you want is to have unexpected costs suddenly emerge.

Below are a 3 simple tips to follow that you can you save money on your next molding project.

  1. Minimize Secondary Processes 
    Any processes outside the molding will require additional setups and cycle times, which will increase your part cost.  These can include processes like painting, and custom inserts.  Instead, consider alternatives like molding your part in a custom color instead of painting, or having inserts molded into the part.
  2. Blanket Orders 
    Say your demand is 100 parts per month.  Will you place an order every month as parts are needed?  Or will you order a year’s worth with blanket releases?  The latter will yield you a lower cost.  This is because you will receive a lower piece due to the higher quantities, and there will be fewer setup charges.
  3. Design for Molding
    Make sure that the part is properly designed for injection molding.  If not, then you run the risk of costly tool modifications and poor part quality.  Need help on what to review?  Here are 4 simple design checks you can do to make sure your part is on the right path to be properly molded.

If you are interested in learning more, or have any additional questions,
then feel free to contact us .  We have a variety of machines and processes
that can be tailored to fit your needs.

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.
