Vero is an all-purpose, high-resolution acrylic plastic. It is printed in layer heights of only 16 – 32 µm and allows high-resolution and high-accuracy prototypes. The material can be combined with other materials (e.g. Tango) to create multi-material parts. Vero is used for sophisticated, close-to-market prototypes or parts requiring high-accuracy.

Sophisticated Prototypes

The Polyjet technology enables producing highly accurate and high-resolution prototypes with smooth surfaces. Vero is rigid, all-purpose plastic which can be used for most prototyping applications.


Multi-Material parts

Vero can be combined with other Polyjet materials to create dual-material prototypes. Popular combinations are Tango – Vero (soft / rigid), to include e.g. sealings or rubber parts or VeroClear (transparent) with opaque Vero (black or white), to visualize interior structures of parts or structures.

Approximate price

  • Pricing for Polyjet is complex, for Vero, you can get an instant quote in our online 3D printing service. For other materials or multi-material prints, please request a manual quote.

Pricing factors

  • Material changes: When changing a material on the machine, a significant amount of material is discarded by cleaning the print heads and pipes.
  • Material consumption: Polyjet is the 3D printing technology with the largest material cost among all plastics. Furthermore, for technological reasons, more material is used than the part requires, sometimes the material consumption is up to 8 times higher than the final part requires (e.g. 800 g material for a 100 g part).

Look & Feel

  • The surfaces are smooth compared to most other 3D printing technologies. However, layer lines can be seen in z-axis, as well as in x-y axis. Only this technology has x-y lines, which are a result from the print head scraping some material from the surface while printing.
  • Surfaces without support material are glossy, surfaces with support material are rougher and dull.
  • The material is an acrylic plastic.

Characteristics

  • Moderate thermal and mechanical stress resistance, very similar to our SLA Detail resin

Symbol wall thickness

Wall thickness
The minimum wall thickness should be no less than 0,5 mm. For long structures or structures that face mechanical stress, the wall thickness should be increased accordingly.

Symbol cavities

Cavities
Cavities can be realized as long as there is a min. 10 mm diameter escape hole to remove excess material. The support is a waxy material which needs to be scraped of. If the escape hole is too small, we cannot access the cavity and support material will remain inside the cavity. Accordingly,  for larger cavities, leave larger escape holes.

Symbol clearance gap

Clearance Gap
In case your file contains several shells, make sure to keep a clearance gap of min. 0,5 mm between the shells, otherwise they could be fused together.

Symbol resolution

Resolution
The minimal details size should not be smaller than 0,3 mm.

Symbol interlocking parts

Interlocking parts
Interlocking parts can be printed as long as there is a clearance gap of at least 0.5 mm and there is sufficient space to remove the support material.

Symbol Bounding Box

Bounding Box
The maximum size of the part cannot exceed 342 x 342 x 200 mm.

Standard Finishing

  • Remove support material

Optional Finishing

  • Sanding
  • Bead blasting
  • Coating

In Polyjet 3D printing a print head is suspended above a build platform. The print head contains several nozzles as well as a UV lamp. During printing, the print head will sweep over the platform, ejecting tiny drops of a light-curing polymer on to the printing platform, and then almost immediately curing it with UV light. The platform then lowers between 16-32 microns (depending on the machine and setting) and the next layer of polymer is applied to the already hardened previous layer. This process continues until the object is completely 3D-printed. Overhanging sections are stabilized during the print by support material, which need to be removed after the print is completed.
