Source: TAV Vacuum Furnaces

"SLM"? You may have heard of AM -- additive manufacturing -- but how about selective laser melting, SLM? Stay on top of your acronyms with this overview on how vacuum furnaces and SLM, an AM technology, can increase fatigue performance of parts.

In this Technical Tuesday, the author not only shares what this technology can do, but also the results of SLM in laboratory studies and research at the University of Parma.

"When SLM processes are conducted within a vacuum heat process, it is possible to make more detailed components which have more intricate forms. Crucially, this means that they will often perform better than would otherwise be the case when they are in use."

Predictive Maintenance and Saving Money

Source: TAV-The Vacuum Furnace Blog

We hear the term “preventative maintenance” often used in the industry. Setting up procedures in advance to avoid unplanned downtime and other avoidable costs is certainly a hot topic. But this Heat Treat Today Best of the Web feature highlights a maintenance strategy that has become increasingly popular in creating better industrial efficiency: predictive maintenance. Read today’s feature article to learn about what predictive maintenance is, how it is implemented in a vacuum furnace system, and how this strategy saves you money.

An excerpt: “Predictive maintenance (PdM) evaluates the condition of equipment by performing periodic or on-line asset condition monitoring. Most PdM is performed while vacuum furnace is operating normally to minimize disruption of everyday operations. This maintenance strategy leverages the principles of statistical process control.”

TAV Vacuum Furnace

What is debinding in metal additive manufacturing (AM)? How do you debind after 3D printing? How do you avoid contamination during metal debinding? Heat Treat Today’s Technical Tuesday article features this Best of the Web piece to answer your questions.

There are several changes that have made new technologies of AM and 3D printing increasingly implemented in the heat treating process. Some of these reasons include: falling costs of 3D printers; increasing geometric abilities; constant rate of the costs of production; and a “drastic reduction” in process waste. Read on to learn how to properly “debind” as you implement these new technologies in the heat treatment process.

An excerpt: “The working temperatures in the debinding phase are in the range between 70 °C (158 °F) and the 450 °C (842 °F), corresponding to the melting temperatures of the various organic compounds.”

"The global dental 3D printing market is expected to grow significantly over the forecast period... Dental 3D printing is a form of modern dentistry and is considered to be wide-spreading in the dental industry. Dental 3D printing involves creating three dimensional solid dental models such as dentures, surgical guides, dental implants, crown, and bridges." From Market Research Future Report: Dental 3D Printing Market

For this Heat Treat Today Technical Tuesday, we are featuring a Best of the Web that highlights cutting edge applications of additive manufacturing (AM). For many in the world of heat treat, AM and 3D are things of the future, oftentimes foreign to the heat treater's processes. What this article reveals is that AM can be utilized in essential and beneficial ways within heat treating.

An excerpt: "...This research and development project managed to optimize the process of making a dental prosthesis using a vacuum furnace. The additive manufacturing allows to create shapes, weights and dimensions customized on different needs and with a precision that has no equal. Strengthened by these peculiarities, the research team worked to further refine and complete the process chain of dental prostheses. Let's see step by step how this process happened."

What happens when the binder reaches the primary pump? How does a heat treater avoid binder condensing?

(photo source: tav-vacuumfurnaces.com/blog/)

In this Heat Treat Today Technical Tuesday, we are featuring a Best of the Web to learn about what happens to binder residue in vacuum furnaces when it is pumped up with process gas. This is the final segment of a four article series on the vacuum sintering process. To read the previous three articles, visit TAV Vacuum Furnaces for the details.

An excerpt: "As regards temperature, a quite natural solution would be to lower the temperature of the captured material. However, it is too costly to go below the values typically reached by industrial chillers. Instead it is easier to change to rotary pumps that work at higher temperatures, not least because these pumps are usually inexpensive. In fact when intending to use a vacuum system without being familiar with the problems of sintering, people tend to use high-performance, high final vacuum level pumps. To obtain this however, it is important..."
