The possibilities of additive manufacturing are constantly growing and are also creating new approaches at BLANK with regard to the investment casting process.

Prototype construction

Additive processes such as prototyping make it possible to recreate each individual manufacturing step using the so-called 3D printing already before cost-intensive tool ordering and sample production. In this way questions can be answered regarding optimal component geometry for the intended use or which of the many possible processing variations is probably the most suitable, which in turn can lead to cost and time savings.

Icon Online-Kalkulator

3D printing online calculator

Just ordering prototype investment castings like from the big online mail order companies: that was our goal!

This claim could be realized with the help of an online calculator for prototypes. Market requirements are dynamic and it is important for us to offer our customers fast availability of investment casting solutions. This is now possible through the integration of the calculator.

Functionality of the calculator

After registering on the platform, simply upload a 3D print file and select the desired process, the desired material (parts up to approx. 1 kg*) and the required number of pieces. The calculator then immediately outputs the corresponding price and delivery time. The order is placed with a further click.

* We offer individual consultations to ensure that a component is suitable for the process.

Online prototypes vs. series production

It is important to distinguish between the serial production of castings and the creation of prototypes with the help of the calculator, because while an aluminium tool is used to produce the serial wax blanks for series production, a 3D printer explicitly takes over this important part in the manufacturing process of the wax blanks for prototype production through the new online calculator.
The subsequent production steps are then identical again, even if they are realized on different systems. This hybrid casting, as we call it at BLANK, especially saves time and, depending on the requirements of the prototype, also costs. Working with an external platform service provider also eliminates time-consuming and expensive test certificates as well as other prototype requirements, which accelerates the handling considerably.

The advantages at a glance

+ savings in time and costs
+ extreme closeness to series and flexibility
+ short delivery times
+ easy handling
+ application of different materials
+ expansion of the service portfolio

A big advantage: extreme closeness to series

The calculator is especially interesting for customers who need a quick test investment casting part for an end application in development and who want to test this component under the conditions that will prevail later. Contrary to metal printing or a prototype milled from solid material, a cast prototype is identical to the later series part regarding material variety, quality and load capacity. This offers the customer enormous planning and development security within only a short time, because the delivery time for investment casting prototypes is only 23 working days. Beside the production of prototypes, the online calculator can also be used to produce spare parts, components and production aids in small and medium-sized series without any problems. The conceivable fields of application are manifold!

Scope of services

Various materials can be selected in the calculator, including heat-resistant and stainless steels suitable for hot gas areas. In addition to metals, the following material groups are also available through the supplier network: Plaster, plastic (also fiber-reinforced), quartz sand and silicone. In total the calculator offers 13 technologies and over 100 materials for 3D printing.

Areas of application

From classic mechanical and plant engineering to medical technology and automation: there are many conceivable areas of application for prototypes. Our core competence is comprehensive consulting. Please feel free to contact us at any time if you have any questions!

Conventional prototype production

BLANK, of course, continues to offer conventional prototyping which is often used for large projects. This differs from the calculator in the provision of comprehensive documentation for the subsequent start of series projects. The knowledge gained from the various design and prototyping phases later enables optimal, customized production in the series.


Possible additive manufacturing processes at FEINGUSS BLANK

  • Additively manufactured wax parts for the investment casting process in order to be able to reproduce first pre-series parts
  • Milled parts made of metal and wax for first trials in the manufacturing and application process
  • Additively manufactured prototypes made of metal, for example using the selective laser melting procedure (SLM)

Whether it is a printed wax part or also a cast part - there are many options available to realize the optimal and most economical solution for you.
