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.

5 Things Engineers Need to Know About Digital Light Synthesis (DLS)

Posted on: July 20th, 2017 by The Technology House

As an engineer, you’re always looking for new and better solutions for your design projects. You’ve likely experimented with traditional additive or 3D printing to produce models and prototypes. Besides being slow, the surface finish and mechanical properties are often suspect. But have you tried the newest innovation in 3D printing? Digital Light Synthesis (DLS)!

Carbon 3D Prototyping and Production DLS Process

Enabled by Carbon’s proprietary CLIP Technology, DLS uses digital light projection, oxygen permeable optics and programmable liquid resins to produce products with much improved durability, resolution and surface finish.

Here’s how it works:

  1. The printer projects UV images through an oxygen-permeable window that sits below a reservoir of liquid resin.
  2. Controlling the oxygen flow forms a “dead zone” layer of uncured resin above the window. Light passes through the “dead zone,” curing the resin above to form a solid part. The object forms as it the build platform lifts it from the resin puddle below.
  3. The finished part is baked in a forced-circulation oven strengthening the materials.

If you’re not familiar with digital light synthesis, here are key items you need to know.

1. Increased Smoothness and Durability

DLS greatly improves upon the surface and mechanical property issues of traditional 3D printed objects. Because this process doesn’t print layers, the surface of the object is much smoother. The higher quality finish combined with the second chemical reaction from the heat of the forced-circulation oven makes for high resolution parts with engineering-grade mechanical properties.

2. Speed to Market

With the Digital Light Synthesis process, you can create prototypes, test them and run your production all in the same process and with the same material. This saves you time and cost while getting your products to your customers faster.

3. Available Materials

3D printing with the DLS process is available with the materials below:

  • RPU Rigid Polyurethane: Tough and abrasion resistant, stiff. Similar to ABS.
  • FPU Flexible Polyurethane: Tough, impact and abrasion resistant with moderate stiffness. Similar to polypropylene.
  • EPU Elastomeric Polyurethane: Highly elastic, resilient. Similar to TPE. 68A durometer.
  • CE Cyanate Ester: High-temperature resistance, strength and stiffness. Similar to glass-filled nylon.
  • EPX Epoxy: Temperature resistant, strong and accurate. Similar to glass-filled PBT or PC/ABS.
  • UMA Urethane Methacrylate: Rigid resins for manufacturing jigs, fixtures and general purpose prototypes. Tough SLA material available in all colors. Similar to SLA resin.
  • DPR Dental Production (NEW!): Fast and accurate. Designed for dental and orthodontic. Similar to UMA or SLA resin.

4. adidas Partnership with Carbon for Futurecraft 4D

adidas is utilizing DLS with Carbon’s CLIP technology to open up new possibilities in shoe design. Carbon developed a revolutionary elastic material for the midsole of adidas’s new product, Futurecraft 4D. Traditional 3D printing was too slow for production, created wasteful part supports and used materials that were brittle.

Carbon’s DLS sped up the process and removed the need for prototyping. They were able to test performance in the design phase. It also created products with no support material, eliminating waste. With the results of DLS, adidas will be able to customize its shoes for optimal performance by sport and by customer.

This is a huge step for the additive manufacturing. These improvements for large volume production can be applied across all industries.

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 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.
