Metal 3D printing ( Metal additive Manufacturing ) enables the creation of many complex models and impossible designs.

Yet, there are some limiting factors that complicate the 3D printing procedure.

The use of 3D printing support material is one of them.

Even if it is an essential parameter that leads to a successful 3D printing result, it is often an obstacle that may lead to part deformation, or leave marks on the 3D printed surface. 

Another Problem is the sticking of the finished part to the base plate.

 

We do have for both problems the solution.

Are You still using a Sawing machine to remove the base plate from a 3d metal printed part?

Disadvantages of a sawing machine to remove the base plate.

  • Dangerous machine for getting wounded at your hands.
  • Big sawing force can deform the part
  • Loss of at least 1 mm of matrial
  • Low precision of cutting
  • No contouring, only straight cut possible!
  • No  3d cut possible.
  • High risk of breaking of fragile parts

And does this looks like your result?

Luckily there are no fingers cut! The result is not good: NO precision!

Or are you still using a hammer, chissel and pincers to remove your parts from the base plate and to remove your metal support structure?

Novicut-M-3D: Affordable high-tech solution for the additive manufacturing industry

Novick Europe has released the Novicut-M 3D-removal line, an affordable wire EDM specific to remove the base plate from 3D metal printing applications.

This model is the latest addition to Novick’s M range of versatile economical wire EDM machines. As the capacity of additive machines continues to increase, it becomes increasingly important for wire EDM offerings to continue to accommodate the growing baseplate and support sizes, Novick says. With a 300 till 500-mm Z-axis stroke, the Noviform-M-3d is suited for the postprocess removal of 3D-printed parts, as well as the production of large molds and aerospace components.

Like other models in the series, the WEDM offers an improvement to the company’s patented molybdenum re-usable wire technology.

With this machine an affordable solution becomes available for every additive manuafacturer.

 

Advantages of our system:

 

  • 2D, 3D, 4D, 5D cutting possible
  • Non contact cutting
  • No single force is applied on the part
  • cutting wide is 0.2mm
  • High precision cutting
  • cutting off the parts from the base plate with only 0.2 mm losses (less printing height)
  • Affordable machine
  • Very low cutting cost (reusable molybdenum wire
  • Differnt models and dimension available
  • High tech for a low price
  • Possible to cut -off in 3D the support structures at a precison of 10µm
  • Low maintenance cost.
  • Accept cad files

One of the most basic considerations before a technician prints a 3D part is how subsequent processes are affected by early workholding decisions.

Shops that plan to take on more additive work may wish to consider machinery that is suited more specifically for this application, as the requirements of an additive part can be quite different

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. 

Workholding

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.

Shops that plan to take on more additive work may wish to consider machinery that is suited more specifically for this application, as the requirements of an additive part can be quite different.

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.
