What can be 3D printed? Talking Materials

What can be 3D printed? Talking Materials

There are many options for metal materials in the world of 3D printing. The most common metals used to print parts are Aluminum, Titanium, Inconel, and Stainless Steel. Each of these metals hold unique properties that set them apart from one another. Depending on the desired use of the part, certain materials are more sought after for specific applications and performance vs others.

Aluminum is widely used in the Aerospace industry because of its lightweight material properties. Aluminum has a high strength-to-weight ratio, low density, and natural anti-corrosive properties meaning it doesn’t degrade due to oxidation. AlSi10 is i3D MFG’s most common aluminum powder and generates a high success rate in parts with thin walls and complicated geometries. Another option available is Al6061, which is a highly ductile and cost effective aluminum that prints more than 50% faster than AlSi10. For this reason, it’s becoming more popular in the AM industry for customers seeking faster build times.

Titanium is another popular choice for customers seeking high corrosion resistance with their parts. Similar to Aluminum, Titanium provides low weight and high strength making it an ideal material for Aerospace and Automotive applications. Titanium is commonly used as an alloying element with Aluminum or Steel to achieve specific properties in terms of ductility, strength, and hardness. Ti64 powder is well suited for projects requiring weight reduction and bio-compatibility. Ti64 typically hardens to 36-41 HRC after heat treatment.

Inconel comes from a family of high-performance alloys, known for its strength and resistance to thermal degradation. Because of this, Inconel alloys (such as IN625 and IN718) hold up when used in high temperature applications. Industries such as the Aerospace and Automotive industry use Inconels because they provide superior heat resistance with a typical heat treatment hardness of 40-47 HRC.

Similar to Inconel alloys, Haynes 282 is a super-alloy developed for high temperature structural applications and provides excellent resistance to strain-age cracking. Haynes 282 also has high ductility making it easy to fabricate and machine, because of this it is a popular material choice for the Aerospace and Automotive industry. Haynes 282 powder typically hardens to 20-32 HRC after heat treatment.

Stainless Steel is commonly sought out for projects that require high resistance to heat and corrosion. Our stainless steel powders are medical grade and typically harden to 40-45 HRC after heat treatment. Due to its characteristics, Stainless Steel is a particularly good choice for parts requiring high strength and hardness. Stainless steel parts can be machined, welded, polished, and coated making them ideal for corrosion resistant applications.

Whatever your desired application is, i3D can help assess your needs and provide suggestions for materials that will cause your project to excel. From prototypes to production ready parts, we’re happy to navigate customers through our selection of high-performance metals to help pick the right material for any given project.

Additive Manufacturing and Post Processing – A synergetic relationship

In the world of Additive Manufacturing, 3D printing is usually the first thing that comes to mind. However there is something equally as important in AM, and that’s strong relationships with post processing vendors. Once a part has been 3D printed, they are often not complete for a customers proposed application. This is why we rely on a synergetic relationship with post processing services to help us provide a complete and finished product that meets the customers criteria. The most common post processing services utilized in the AM industry today are Post-Machining, HIP treatment, and Anodizing.

Our friends at Cascade Precision Inc, an Oregon based AS9100 and ISO9001 certified Post-Machining company help to post process parts that require further assistance before they are considered complete. Post-Machine shops utilize high precision CNC machines to either lath or mill a part to meet given parameters or tolerances.

When parts need their density increased, heat combined with pressure is applied to the material from all directions in a manufacturing process called HIP (Hot Isostatic Pressing). Argon is the most commonly used pressure medium. After optimal HIP treatment is applied to parts tensile strength can increase significantly based on the ductility desired by the customer.

When aiming to give a part a certain cosmetic look, customers rely on anodizing services. Anodizing hardens and coats parts to make them tougher and give them a specific color chosen by the customer. Anodizing can differ between soft and hard coating, soft coating provides a thin coating while hard coating provides a thicker coating to help prevent corrosion.

Looking to the future, the importance of maintaining a synergetic relationship with post processing services cannot be overlooked. This relationship is crucial to meet the dynamic demands of the AM industry. i3D is committed to establishing strong working relationships with post processing services in order to provide the best product possible to suite our customers needs.

Why 3D Printing is Predicted to Produce 50% of Parts & Components

3D Printing Predicted to Produce 50% of Parts & Components

A recently released Gartner study found that 3D printing is not only widely used for rapid prototyping and product development, but that ” it (3D printing) was starting to play a significant role in short run production of finished products.” What evidence does Gartner have to support that prediction? First, they performed a survey of 300 people from a multitude of 100+ employee organizations and 37% of them use end-use quality 3D parts.   Read more

DIRECT METAL LASER SINTERING (DMLS) FOR CAVITIES AND CORES

You needed your Injection Mold Tooling when? Yesterday??

The Direct Metal Laser Sintering (DMLS) process has been rapidly gaining recognition as perhaps one of the most powerful technologies available in the additive manufacturing world. The recent material parameter developments coupled with outstanding resolution and speed of fabrication are making DMLS cavity and core inserts a very successful tool that can be used to shorten lead times, reduce costs and push multiple projects through in the same amount of time that one project normally takes. i3D Manufacturing can print mold cavity and core inserts within days, giving end-use customers competitive advantages in real time-to-market, product development, and small batch production. Our Aluminum, Maraging Tool Steel and Stainless Steel mold tools can be post processed in all of the same ways as cast or machined parts, from polishing to welding to anodizing. 
 

Interchangeable Cavity and Core Insert Blocks

i3D™ owns North America’s first EOS M290 DMLS 3D Printing machine. As an official Material Process Applications (MPA) for EOS, i3D™ prides itself on its DMLS material and 3D print application innovations. Our interchangeable mold tool cavity and core universal base provides injection molders flexibility in switching out cavity and cores in small and medium batch runs at economical tooling and change-over costs.
 
With the latest, highest quality equipment i3D™  is able to achieve densities at nearly 100%, allowing for any finish requirements to the various 3D printed cavity and cores. Lattice and honeycomb designs specially tailored for optimal part cooling and heating add more value to the mold block design options. Injection molders can offer their clients tool design, manufacture, and part production in as little as 3 weeks. The process is all on-shore, protecting customer designs and avoiding costly tool change expense. Rapid Injection Tooling is often used as a bridge between prototyping and production but, not always. If you have low volume injection molding requirements, rapid tooling could be the answer for you. 
 
Aluminum (AlSi12)
AlSi12 is our most common DMLS Aluminum powder and is perfect for projects with good thermal and low weight considerations. It is an optimal metal for parts with thin walls and complex geometries
Maraging “Tool” Steel (MS1)
Our Maraging Steel powder has excellent strength and mechanical properties. MS1 is a pre-alloyed, ultra high strength powder most commonly used for tooling applications. Its chemical composition corresponds to U.S. 18% Ni, Maraging 300, European 1.2709 and German X3NiCoMoTi 18-9-5. After heat treatment, MS1 typically has a 50-53 HRC.
Stainless Steel (PH1)
PH1 is a medical grade, sterilisable, corrosion resistant steel. It is primarily used in Medical, Firearms, Energy and Automotive applications. After heat treatment, PH1 hardens to 40-45 HRC. Our Stainless steel equivalents include 15-5, 17-4 and 316. Parts made from EOS Stainless Steel PH1 can be machined, spark eroded, welded, micro shot peened, polished and coated if required.

Additive Manufacturing for Firearms

Additive Manufacturing Helps Oregon Firearms Industry Stay Innovative

With big game hunting season winding down in Oregon, it seems appropriate to give a nod to our friends in the firearms industry. Oregon has a long and rich history in firearm accessory manufacturing. Its premier manufacturers epitomize innovation and quality – think Warne Scope Mounts, Nosler, Leupold, and Grovtec. These companies were born from Northwest outdoorsmen’s desire for quality products with superior performance. They’ve become household names today because of their focus and commitment to innovation.

Additive manufacturing, or 3D printing, is helping Oregon’s firearm industry stay a step ahead of its competition. Complex designs that are expensive or even impossible to traditionally manufacture can be 3D printed in metal using Direct Metal Laser Sintering (DMLS) offered by i3D MFG™ and other similar service bureaus. Custom part builds, rapid market launches, and small batch production are all cost effective mean of production using 3D manufacturing. Unlike previous 3D print technologies, DMLS does not use binding agents, therefore, parts near 100% density, and are comparable to machined and high quality cast parts. In fact, this past summer both the FBI and the USSOC commenced in firearms projects using DMLS.

Additive Manufacturing benefits for Firearms

Latticed geometries, conformal cooling lines, organic channels, and single part production of multiple part assemblies are common 3D design features. Since 3D manufacturing is a no-waste process, exotic metals offering superior strength and heat properties are cost effective. Titanium, Inconel, and Steel are the most widely produced DMLS metals in the firearms industry. Lead times with 3D printing allow firearm accessory manufacturers to reduce R&D and market launch to weeks or months compared to months and years. Multiple versions of a design can be 3D printed in the same build, allowing R&D version testing or custom production in days.

i3D™ is proud to be innovating along with Oregon’s industry leaders. Oregon’s proud tradition of recreational firearms and firearm accessory manufacturing will continue to grow and beat its competitive because of their forward thinking and adoption of next generation technology in product development. We hope all the hunters out there had a successful season!
