As manufacturers accept and implement new technologies into their operations, downstream processes often need to be adjusted to accommodate the type of work that then comes down the pipeline. One example is additive manufacturing or 3D printing. While many of the first commercial 3D parts were for specialty aerospace and medical applications, the technology slowly but surely has crept into much broader manufacturing settings, including the mold and die industries. Because of the unprecedented nature of 3D printing, these adjustments touch all areas of machining processes.
One of the most basic considerations before a technician prints a 3D part is how subsequent processes are affected by early workholding decisions. One factor that complicates these decisions is the great variance in 3D printers. Some additive machine manufacturers come from the machine-tool world and have quickly leveraged that experience to provide easy solutions just as they would with a traditional CNC machine. Conversely, those that have led innovation specifically in 3D printing often have less experience with questions pertaining to workholding and so may require more ingenuity to strategize secondary operations.
Naturally, one trend that is taking root quickly is for traditional tooling suppliers to partner with original equipment manufacturers (OEMs) for machines to provide integrated solutions. With validated systems at the OEM level, it is possible for tooling manufacturers to make the secondary operations just a little less laborious. Alternatively, for machinery without an established tooling solution, it may be possible to produce tombstones or other custom fixtures to expedite the setup process, though these would be less transferable from one operation to the next. For example, a part that requires both wire EDM removal and sinker EDM finishing likely would not be able to use a tombstone for both.
Moreover, operators should be aware that because 3D printing is not a perfectly accurate process, virtually all applications would still benefit from the inclusion of reference or datum surfaces for more accurate pickups.
Additionally, many shops would benefit from reviewing machine specifications in regard to the type of work that they do. Shops that plan to take on more additive work may want to consider machinery that is suited more specifically for this application, as the requirements of an additive part can be quite differently than other processes. Often, wire-EDM work on an additive part is limited to the removal of supports or of a baseplate, meaning that the goal is no longer fine finishing or extreme precision but capacity, cutting speed and reliability under unfavorable conditions.
This change has put equipment manufacturers in a somewhat difficult predicament, as they design around very different specifications than those that the additive market demands. As additive applications continue to grow in size at a fairly rapid pace, the Z height required to machine these parts with EDM also continues to increase.
And yet, while this application does not necessarily require an extreme surface finish and micron accuracy, the only machines capable of accommodating these large workpieces are often the premium, large-capacity models in the EDM lineup. These premium very expensive models tend to offer many capabilities that, while impressive, are not strictly necessary for the application at hand, and thus add unnecessary cost.
Moving forward, Novick developped low cost models that target the additive marketplace more adequately, with low investment cost, low wire consumption cost, with fast cutting speeds, few wire breakage and large capacity but without advanced technology for six-, seven- or eight-pass finishes. These machines will be a much better fit for the type of additive work that looms on the horizon without breaking the bank.

Selective laser melting is an additive manufacturing process used to build 3D metal objects using high-power laser beams. A thin layer of powder is applied to the build platform in the first construction process step with a squeegee (or a combination of several squeegees). A laser melts the metal powder with temperatures of up to 1,250 °C in the laser focus at the coordinates specified by a CAD file. The construction chamber is filled with an inert gas to prevent oxidation of the metal throughout the construction phase.
Selective Laser Sintering (SLS) is a 3D printing process that uses laser radiation as an energy source to make 3D objects out of plastic. In the first step, a thin layer of powder is applied to the build platform using a squeegee, a combination of several squeegees, or a roller. The layer thicknesses range from 0.05 mm to 0.15 mm, depending on the resolution and installation. After the powder is applied uniformly, the construction chamber is heated to just below the melting range of the respective plastic and melted locally by a laser at the points where the component is to be formed. Subsequently, the build platform lowers by one layer of thickness and the process begins anew. The process repeats until the last layer of the 3D model has been printed.
Selective laser melting (SLM), also known as direct metal laser sintering (DMLS) or laser powder bed fusion (LPBF), is a rapid prototyping, 3D printing, or additive manufacturing(AM) technique designed to use a high power-density laser to melt and fuse metallic powders together. In many SLM is considered to be a subcategory of selective laser sintering(SLS). The SLM process has the ability to fully melt the metal material into a solid three-dimensional part unlike SLS.
Electron-beam additive manufacturing, or electron-beam melting (EBM) is a type of additive manufacturing, or 3D printing, for metal parts. The raw material (metal powder or wire) is placed under a vacuum and fused together from heating by an electron beam. This technique is distinct from selective laser sintering as the raw material fuses having completely melted.
Multi Jet Fusion (MJF) is a new powder-based 3D printing process that produces high-resolution and precise 3D objects with low porosity and high surface quality. In contrast to selective laser sintering (SLS), MJF completely dispenses with the use of a laser beam. An inkjet print head prints components by applying two different binder fluids to the surface of the powder bed.
