Recently, we worked alongside the Solar Gators to help create their upright struts for their electric racecar. Follow this project from powder to part.
The parts are built on our Arcam EBM (Electron Beam Melting) machines using Ti6Al4V. As an extremely hot powder bed fusion process, the powder that is not melted to form the part, sinters together, resulting in a briquette of titanium powder. This then needs to be blasted with the same powder to remove and recover any excess. Both revealing the parts within and allowing for the powder recycling process to begin.
Once the part has been successfully blasted and all loose powder has been removed from any internal cavities, the next step is fettling. Here, our specialized team removed all the support structures that helped the parts build correctly.
After the part has had all of the support structures removed, it will undergo the required post-processing. In this instance, the parts needed to be tumble-finished to achieve a smoother surface roughness.
To ensure conformance of metrology and validate components to our customer's specifications, we inspecting using a 3D Scanner.
Additive Manufacturing produces complex geometries which are traditionally challenging to measure. This is why we use 3D scanners and a vision system to perform measurement and analysis of 3D surface profiles.
Once the parts are ready for dispatch, we carefully package them up and utilize our global partners DHL and FedEx to ensure fast delivery speeds worldwide. In this case, the parts were on a deadline for the graduation of some of the key members. From sending the parts from New Zealand, they were received in The USA only two days later.

Surface Finishing & Treatments
Surface finishing and post-processing treatments are crucial in an engineered environment and are often highly dependent on the end application of the design. For example, abrasive surfaces (such as the EBM ‘as-built’ surface roughness of 16um 22um Ra) can be ideal for bonding situations, smooth surfaces can promote a more consistent flow of fluid, and machined surfaces offer improved fatigue life for high-stress use. While we are able to meet a wide range of finishing options, special consideration must be applied to ensure you are taking advantage of the most appropriate finish.
Surface finishing and treatment outcomes are highly dependent on the geometry and method used. For example, internal cavities and small radii can be challenging to surface finish with limited tool access.
We have multiple in-house finishing capabilities, including:
On request we can also offer:
If you require specific surface roughness or aesthetics, please note that typical surface finishing will remove approximately 0.4mm of material. If surface finishing is specified on simple geometries our team can add this material allowance, however, if the surfaces are complex we will request that you allow for this material in the model you provide to us.
It is important to note, that not all surfaces can be mirror polished, such as internal cavities and tight radii. This is highly dependent on geometry and in most cases, outside volume production will be performed manually. Please contact our team to discuss what option would suit you.
Product Marking & Traceability
Zenith Tecnica provides the ability to mark products with branding, certifications and identification labels.
Labels allow for high levels of traceability to all materials, powder, and processes used to manufacture components. For full traceability right down to position in a build, serial numbers can be printed directly on components, or lot numbers can be laser marked during the inspection. Customers can use this capability to enable identification during assembly and traceability throughout its service life.

Hot Isostatic Pressing (HIP) Heat Treatment
HIP heat treatment is commonly used in the Aerospace and Medical industries to improve material performance. We work closely with our US-based partner to provide our customers with access to this service. The HIP process puts components under high pressure and temperature to improve the internal structure.
For highly loaded or dynamically loaded thin-walled geometries, our team advises HIP heat treatment and qualification with physical testing. For the best material performance, HIP should be used in conjunction with surface finishing to improve both the inside and outside of the material. HIP will typically require an additional 2 weeks of lead time to be processed.
We work closely with our partners who are experts at working with AM designs and Titanium alloy. Together we provide the ability to machine near-net EBM components which offers a hybrid manufacturing approach. This enables the benefits and flexibility of Additive Manufacturing with the accuracy of Machining. Machining is often used in conjunction with EBM for components that require tight assembly tolerances.
Please contact our team to request your copy of our Technical FAQ to learn what Geometric Dimensions and Tolerances (GD&T) are achievable.
Our metrology capabilities enable us to validate that components meet our customer’s specifications. Additive Manufacturing produces complex geometries which are traditionally challenging to measure and conform.

Process Validation & Qualification
Zenith Tecnica has qualified our EBM machines to produce a wide range of spacecraft components and medical devices. We continually monitor and control our processes so to ensure they are operating within set limits to provide our customers with confidence in the components they receive.
We have a standard quality plan, sometimes known as a standard operating procedure, that dictates the requirements for every part produced at Zenith Tecnica. Some customers may have additional requirements and our team captures these in a tailored quality plan that outlines any parts of the process that are different to standard.
We can supply a certificate of conformance with your orders to provide traceability to all standards and specifications used during manufacturing.
Titanium is an incredibly versatile material. Yet, it has remained remarkably underutilized as it was previously difficult to take advantage of. With the progression in technology and growth of powder bed fusion 3D Printing, anyone can now take advantage of Titanium's potential.
With such a capable material at our fingertips, we have been able to concentrate our efforts towards becoming world leaders in the art of titanium alloy manufacturing. Our commitment to titanium coupled with our humidity and temperature-controlled machine environment, we reduce any risk of cross-contamination and material impurities.
Electron Beam Melting (EBM) is a Powder Bed Fusion Additive Manufacturing (AM) process. Utilising an incredibly powerful beam of electrons, this form of AM heats and selectively fuses metal powder together. The process begins with an extremely thin layer of metal powder spread across a build plate and pre-heated. Once the desired heat is achieved, the beam accurately melts areas of powder at speeds of up to 8000m/s, which is approximately 28,800 kilometres per hour.
Once the layer has finished being melted, the plate descends a distance less than the average width of a human hair. From here a new spread of metal powder is applied and the next layer begins. The design of the finished part is achieved through the creation of a 3D CAD Model that is digitally sliced into thousands of individual layers, acting as a blueprint for the beam to follow.
Production of unique and complex geometries can be achieved with Additive Manufacturing (AM). EBM enables high productivity manufacturing of tall and thin-walled components, parts with large cross-sectional changes and the ability to consolidate assemblies.
Additive Manufacturing can exploit the high strength-to-weight ratio of titanium better than more traditional manufacturing methods by making it possible to produce thin and complex geometry components.
Components can be designed using the latest optimisation techniques to reduce mass. Our customers have optimised these assemblies to reduce mass for thermal loading in space and mechanical loading in many high-performance applications.
Titanium is naturally corrosion-resistant, assisting its performance in harsh environments such as saltwater. In particular, titanium pairs well with carbon fibre composites due to their position on the galvanic series. This pairing leads to longer service life through reduced festering.
Titanium is widely used in orthopaedic implants due to its bio-compatible nature, corrosion resistance, and specific strength. Using AM, surgeons and implant manufacturers can create patient-specific devices on tight deadlines. This opens the possibility to incorporate metal porous structures for osseointegration to improve patient outcomes.
High productivity rate
Zenith Tecnica chose GE Additive Arcam EBM machines as they typically fit more parts per build than alternatives. This enables filling an entire 3D build volume of parts. Combined with the speed of EBM, this results in faster lead times through the efficient build process.
Tall thin-walled components
The sintered powder bed surrounding melted components in the EBM process supports thin-wall components laterally. Allowing for more design freedom with large lightweight structures.
Reduced internal stress
The EBM process takes place in a vacuum chamber and maintains a high-temperature powder bed throughout the build process. The results in components being stress relieved and machineable straight after unloading without further heat treatment.
Large cross sectional Areas
The EBM process has enough speed and power to melt large volumes and thick walls without distortion when compared with similar powder bed fusion technologies. This is useful for part consolidation and structural components which require extra material for high strength and stiffness.
Electron Beam Melting Additive Manufacturing unlocks the ability to tightly stack parts together using the entire 3D volume of the build. Based on your order quantity, we can find the most cost-effective solution for building your parts. Whether that means placing them on a regularly launched “Ride-Share” build, where space is shared between customers, or launching a fully “Dedicated” build for the lowest unit cost for larger quantities.
To get started, all we require is a 3D model of your design and a basic understanding of your manufacturing specifications (quantities required, schedule etc).
Our team can also collaborate with you to define a quality plan and validate a process to meet your monthly, quarterly, or annual requirements on time. Once the order is confirmed, we will stay in constant communication on progress and ensure there are no surprises.
At a minimum we require:
