Our guides are designed to give an idea of the possibilities offered by the technical solutions and the materials that we are able to supply.

Guides are currently are available about the different types of materials and styles of finishes, both for prototypes and pre-series production.

Finiture per stereolitografia

Stereolithography finishes

Prototypes made in stereolithography can be finished in various ways, from basic finishing to RAL varnishing. Usually, the finishing is done only on the aesthetic side, unless otherwise agreed and with the exception of the transparent effect that requires finishing on both sides.

FB - Basic finishing

Finitura basic

This type of finishing is the basic finish directly derived from the machine, without further processing, except those strictly necessary to separate the object from the support platform. Surface quality depends heavily on machine positioning that can highlight or hide process stratification.

FS - Standard finishing

Finitura standard

This is the most common finish, consisting in sanding and sandblasting the piece, which thus assumes a translucent white appearance.

FT - Transparent finishing

Finitura trasparente

With the Watershed 1122XC material, it is possible to obtain a transparent glass-like finish. This is possible by sanding, polishing and painting the workpiece on both sides, compatibly with the geometry of the part.

FM - Metal finishing

Finitura metallizzata

In this case, the prototype, after being polished, is subjected to vacuum metallization. The final surface is glossy and has a highly reflective power, but may have slight cracking, which may also occur over time, due to the different dilatations that characterize the resin and the metal.

FP - Painted finishing

Finitura colorata

This type of finish is obtained by painting the model with a color you choose, glossy or opaque (RAL or Pantone shades are possible). In this way you can also get opaque metal-like finishes.

Finiture per pre-serie

Finiture per pre-serie

With silicone molds you can get a good variety of finishes, as explained below. All described effects (except metallic ones) can be applied on a pigmented support or on a transparent base (colorless or colored). Unless otherwise agreed, the finish is only made on the aesthetic side. Exceptions are transparent pieces, which are nevertheless finished on both sides.

FLL - Glossy smooth finish

Finitura lucida

This type of finish is obtained by polishing as much as possible the master prototype. The pieces thus obtained have a glossy finish and, if the material is transparent, the effect is similar to glass. Caution: this finish is hard to get and very time consuming; moreover, defects and scratches are very noticeable on the parts thus finished.

FLO - Smooth matt finish

Finitura opaca

This finish, characterized by a smooth but non-glossy surface, is one of the most used and versatile finishes, easily available on almost all geometries. If the casting material is transparent, the effect is that of mildly acidified glass.

FGL - Slightly rough finish

Finitura goffrata leggera

The FGL surface has a light roughness on it, which can have aesthetic purpose, but can also help hiding any irregularities that may occur in most complex prototypes. Also this is a very used and versatile finish.  On transparent material, the effect is similar to sandblasted glass.

FGG - Very rough finish

Finitura goffrata grossa

In this finish the texture is more evident. In some cases, high surface roughness can make defect correction difficult and can also reduce the mold life.

 

FST - Structured Finish

Finitura strutturata

A very special finish, characterized by a high roughness, which simulates a fibrous material. It greatly reduces die life.

 

FML - Polished metallic finish

Finitura metallizzata lucida

This type of finishing is achieved by vacuum-vaporizing metal. The coating is a few microns and therefore has aesthetic and non-structural purposes. The vacuum metallization procedure increases production times.

FMS - Finitura metallizzata satinata

Finitura metallizzata satinata

This type of finish is obtained by painting the parts with a matte metallic paint. Execution time and cost are lower than for vacuum metallization, but with this method you can not get the glossy effect.
