DMLS additive manufacturing Archives - Perfect 3D Printing Filament

We’ve got three upcoming webinars to tell you about in this week’s roundup, with two taking place at the same time on June 24th. The first one is focused on metal 3D printing, while the second is about how to use the technology to unlock massive value, specifically in the food and beverage manufacturing sector. Finally, Stratasys is holding the first of two webinars about aerospace 3D printing on June 25th.

BIG 3D Metal Printing Webinar

This Wednesday, June 24th, at 11 am EDT, EOS North America and Additive Manufacturing Customized Machines (AMCM) are hosting the free “BIG 3D Metal Printing” webinar, focusing on how technology advancements in additive manufacturing are driving applications in commercial space hardware. In this one-hour course, attendees will learn why metal 3D printing is more accessible, what DMLS technology is, what materials can be leveraged, and how customized 3D printing is continuing to advance. The speakers – Martin Bullemer, Managing Director of AMCM; Dr. Ankit Saharan, Manager of Research and Applications Development at EOS North America; and Graham Warwick, Aviation Week’s Executive Editor for Technology – will discuss what metal 3D printing is truly capable of creating.

“The challenges of fast development and innovation have lessened because of industrial metal 3D printing (additive manufacturing, or AM). Whether propulsion, structural, or integrated componentry, AM is accelerating the latest space race.

“Now, AM is moving quickly to meet even greater requirements—such as fully 3D printed combustion chambers with high-performance features, lighter weight structural components, or even fully 3D printed satellites. The latest advancement? Fully printed 3D components up to one (1) meter tall.”

3D Printing for Food and Beverage Manufacturers

Ultimaker is also holding a free webinar at 11 am EDT this Wednesday, titled “3D printing for food and beverage manufacturers.” If you don’t want to miss either one, you also have the option of attending the first broadcast session of this webinar at 5 am EDT. Even if you’re not in the food and beverage industry, this 50-minute webinar could still be useful, as the company “will be revealing some of the best ideas and strategies that we use to help our biggest customers unlock massive value with 3D printing.”

Ultimaker’s Director of Community Development, Matt Griffin, and Application Engineer, Jeremy Evers, will discuss which AM applications in this industry are currently working, and how to use the technology to achieve excellent results, such as reduced costs, increased line uptime, and optimized efficiency. During the webinar, they will give examples of industry-proven applications that have saved Ultimaker customers a lot of money, provide two sample criteria that the company’s application engineers use to determine which applications can achieve the largest ROI, discuss the future of 3D printing in the food and beverage industry in a post-coronavirus market, and more. Additionally, attendees will have the chance to participate in a live Q&A afterwards. Register here.

Stratasys Aerospace Webinar Series

This Thursday, June 25th, at 10 am EDT, Stratasys will be hosting the first in its new aerospace webinar series, titled “Challenges Of Manufacturing Aircraft Production Parts.” Niccolò Giannelli, Aerospace Application and Account Manager EMEA for Stratasys, will speak during this hour-long webinar about how certifying 3D printed aircraft parts for installation is easier with the company’s Aircraft Interiors Solution (AIS).

Some of the topics to be discussed in this first webinar include the value of both Stratasys’ AM solution and additive manufacturing for aircraft production parts, what comes in the Stratasys AIS package, and the improved performance of airline companies after they’ve implemented the Stratasys Aircraft Interiors Solution. Register here. The next webinar in this series will be held on June 30th.

As 3D printing with metal continues to expand for industrial users around the world, so does the study of materials like powders, unique alloys, and a range of composites. In this study, outlining their findings in the recently published ‘Strength analysis of Ti6A14V titanium alloy produced by the use of additive manufacturing method under static load conditions,’ researchers focus on the uses of titanium alloy Ti6Al4V and comprehensive analysis of mechanical properties after printing via direct metal laser sintering (DMLS).

For many applications, the benefits of 3D printing and additive manufacturing processes overshadow more conventional methods for the creation of devices like dental implants, rocket engine components, car parts, and more. While greater affordability is key, so is the ability for many users to create parts that may never have been possible before—or even more notable, perhaps, is the option to scan older parts that have become obsolete and re-create them via 3D printing (especially helpful in applications like automotive and for the military).

Medical devices such as implants are often made from alloy due to the following advantages:

High mechanical properties
Low density
Corrosion resistance
Biocompatibility

Test sample dimensions.

Heat treatment is common with the use of metals, as it improves mechanical properties. Methods such as hot isostatic pressing (HIP) are often used; however, in this study, the researchers use DMLS additive manufacturing to create the samples to be tested for viable mechanical properties.

Physical form of research samples: (a) turned from a drawn bar, (b) manufactured by the additive method DMLS.

The team created samples in the form of annealed drawn bars (12mm in diameter) as well as a set created via DMLS on an EOS M280W machine, and annealed afterward.

“The printing process was characterized by the following parameters: laser power 200 W, minimum layer thickness 30 μm, scanning speed up to 7 m / s. The sample print direction was consistent with the Z axis,” explained the researchers.

The applying scheme one layer of the sample by the DMLS method.

Strength of the first samples was found to be lower in comparison, while hardness related different values:

“The difference in results is related to the method of sample preparation by the additive technology and the external load it has been subjected to,” stated the researchers.

“Slight changes in the hardness value in the x-plane of unloaded samples indicate similar mechanical properties of the material produced by the DMLS method.”

Samples for hardness tests: (a, b) samples from a drawn bar, (c, d) samples made using the DMLS method before tensile tests, (e, f) samples made using the DMLS method after tensile tests.

The team of researchers also noted that in this case, variances in hardness (between x-y and x-z) could be due to 3D printing of material grains, combined with deformations caused by the axial load.

Testing of sample DMLS macrostructures demonstrated obvious changes related to tensile load, indicating that it may also again be due to 3D printing—as well as set parameters and direction of material layers. The researchers compared macrostructures both before and after tensile loading, realizing that plastic deformations then occurred, and were plainly visible caused by the load line.

Because titanium is used in a host of 3D printing and AM processes today, this material is an ongoing source of study from use with composites, to medical devices like sternum or hip implants, printing with glass, and more.
