BEGO VarseoWax CAD/Cast – a resin for 3D printing of casting models

BEGO VarseoWax CAD/Cast is a specialist, light-curing 3D printing resin designed for the production of fired prosthetic objects using the digital CAD/Cast process. The material has been developed for dental laboratories seeking to combine the precision of CAD design with the predictability of traditional casting. This enables the printing of components which, once invested, can be fired with a very low ash content, creating optimal conditions for achieving smooth, accurate and well-fitting castings.

The product is particularly recommended for work such as partial dentures, crown and bridge structures, inlays, onlays and veneers intended for further casting. It is the solution for laboratories that require repeatability, dimensional stability and high-quality print surfaces. VarseoWax CAD/Cast resin helps to reduce the risk of porosity, deformation and unpredictable behaviour of the object during investment casting.

Applications of BEGO VarseoWax CAD/Cast

BEGO VarseoWax CAD/Cast is a material for dental laboratories working with digital technology. The resin is used to print objects that are not the final restoration in the mouth, but rather a component of the technological process preceding casting. In practice, this means that the print acts as a precise master, which, after being embedded in the investment material, is fired out, and its place is taken by metal or another casting material in accordance with the laboratory’s procedure.

The material is suitable for cast partial dentures, where accurate reproduction of clasps, saddles, connectors and thin structural elements is essential. It can also be used for crowns, bridges, inlays, onlays and digitally designed veneers prepared for casting. This means that a single resin can be used for a wide range of laboratory scenarios, giving the dental laboratory greater flexibility in production planning.

How does the material cast using CAD/Cast technology work?

CAD/Cast technology combines computer-aided design with traditional casting principles. First, the technician designs the work in CAD software, then prints it using 3D printing resin, prepares the print for investment, pours in the investment material and carries out the sintering process. At this stage, the master model should come out of the mould as clean as possible. This is why low ash content and stable material behaviour at elevated temperatures are crucial.

VarseoWax CAD/Cast has been developed to burn out without leaving significant residues. The low ash content, declared at less than 0.1% at 700°C, helps to reduce the risk of contamination in the mould. In practice, this can result in a smoother surface, fewer pores and better fit accuracy of the cast piece.

Dimensional stability prior to firing is also important. If the print warps during investment, the accuracy of the digital design becomes irrelevant. This is precisely why the manufacturer emphasises the dimensional stability of printed objects, which allows for safe investment even with slender features. A well-prepared print retains its geometry, and the entire process becomes more predictable.

Why does low ash content matter?

In sintered materials, it is not only the accuracy of the print that counts, but also what happens in the furnace. Ash residues can compromise the purity of the mould, affect the surface of the casting and increase the workload during finishing. BEGO VarseoWax CAD/Cast has been designed for residue-free firing, making it a good choice where the laboratory demands high-quality castings and wishes to minimise the risk of errors.

Ash content of less than 0.1% at 700°C means very little residue after firing. For the technician, this translates to cleaner casting conditions, fewer surprises and greater control over the result. This is particularly important for partial dentures, where complex geometry and numerous thin elements place higher demands on the material.

Shape stability and fit accuracy

The accuracy of prosthetic work depends on the entire process chain: scanning, design, print parameters, post-processing, investment, firing and casting. The resin must not be the weak link in this process. VarseoWax CAD/Cast offers dimensional stability, which helps to maintain the designed geometry during preparation for casting. As a result, the mould is based on a print that should not lose its shape when handled correctly.

The high strength of the models facilitates handling of the prints, cutting away supports and preparation for subsequent stages. If further processing takes place immediately after printing, local documentation indicates that the objects may not require additional light curing, which helps save time. In practice, however, you should always follow the manufacturer’s current instructions and the parameters specified for the specific printer and material version.

Workflow with BEGO investment materials

A major advantage of the material is its use within a system. The manufacturer highlights the possibility of using the resin with VarseoVest investment materials, which are designed specifically for 3D-printed objects. VarseoVest C&B is used for crowns and bridges, whilst VarseoVest P plus is specified in the documentation for cast partial dentures. This combination of materials simplifies the process from design to casting.

Investment should also be straightforward for slender details. This is important because thin elements of cast partial dentures or delicate edges of crowns can be prone to errors if the investment material does not encase them correctly. BEGO’s systematic approach helps to minimise cracking and tearing of the investment, whilst supporting a stable workflow in the laboratory.

Compatibility and printing parameters

BEGO VarseoWax CAD/Cast is a light-curing resin designed for 3D printing, and the documentation specifies use at a wavelength of 405 nm. The manufacturer also provides material files for selected Asiga MAX printers using DLP technology at 405 nm and 385 nm. This means that before starting work, you must select the material profile for the specific device and light source.

Who is this resin for?

The product is intended for dental laboratories, prosthetic workshops, CAD/CAM centres and professional users producing cast prosthetic work. It will be a good choice for workshops printing series of work, but also for smaller laboratories that wish to reduce manual modelling time and improve repeatability.

Advantages in day-to-day work

• Reduced preparation time for models compared to manual wax modelling.
• Ability to reprint a job from the same CAD file.
• Better control of geometry in designs with thin elements.
• Repeatable process when using the correct material profiles.
• Lower risk of mould contamination thanks to very low ash content.
• Practical print strength facilitating transport between work stages.
• A professional material for laboratories looking to develop digital prosthetic production.

How to prepare a job for printing?

The best results begin even before the resin is poured into the tray. The CAD design should be prepared with casting technology in mind, not just the printing process itself. It is worth ensuring the correct thickness of the components, logical placement of supports and orientation, which reduces the risk of deformation and facilitates subsequent removal of the structure. The print must be stable, but at the same time should not require excessive mechanical processing.

After printing, follow the manufacturer’s instructions: remove excess resin, clean the components, cut away the supports and prepare the object for investment. If the work is to be carried out immediately, local documentation indicates that additional polymerisation may be omitted, but the decision should always be based on the current protocol and compatibility with the device. In dental 3D printing, the procedure is just as important as the material itself.

What does the buyer gain?

When you buy BEGO VarseoWax CAD/Cast, you are investing in a material that supports professional 3D printing in prosthetics and helps to transfer the casting process to a digital working environment. Instead of manually building each master, you can design it in CAD, print it with high repeatability, and then use it in the traditional casting process. This solution is particularly attractive for laboratories looking to increase efficiency, improve quality control and reduce the number of reworks.

If you are looking for a 3D printing material for casting, resin for cast partial dentures, sintered resin for crowns and bridges, or professional dental resin for the CAD/Cast workflow, this product meets those needs. It combines the technical specifications required in the laboratory with the practical convenience of working within the BEGO Varseo system.
