Inverted laser SLA · DWS

Inverted laser SLA 3D printers

Stereolithography, upside down. The laser shines up through the clear floor of the resin tank and the part is drawn up out of the resin as it grows. DWS builds it from compact professional 3D printers to automated industrial production systems.

How inverted laser SLA works.

An upside-down form of laser stereolithography. A laser shines through the transparent bottom of the resin tank and traces each layer and the platform lifts the part out of the resin as it grows. It is a variation of SLA, not a different process: the difference is which way up the part grows.

A shallow working volume

A shallow working resin volume, so there is no deep vat to fill around the whole part.

Manageable material changes

Smaller resin quantities and removable tanks make changing material more manageable.

Solid-state BlueEdge® lasers

From one laser on the DW line to twelve on the XCELL 900Q.

The DWS range.

Typical uses: detailed prototypes, casting patterns, specialist tooling and production parts, depending on the machine and material. Every DWS is priced on configuration.

Dental labs and clinics: ask us for the XFAB PD range.

After the print.

Every resin part needs the same short finishing routine before it is ready to use.

  1. 01

    Drain and clean

    Lift the part from the vat and wash off the uncured resin.

  2. 02

    Remove the supports

    Snip or break away the support structure and tidy the marks.

  3. 03

    Post-cure

    UV light, plus heat for some grades, brings the resin to its full properties.

  4. 04

    Finish

    Sand, prime, paint or polish clear, as the part needs.

Other ways we print.

Inverted laser SLA is one of four. The right choice depends on the part, the material, its size and how many you make.

MSLA · masked stereolithography

Detailed resin printing in your design workspace

A light source shines through an LCD screen beneath a tank of liquid resin. The screen acts as a mask, exposing the shape of a whole layer at once. The platform lifts, fresh resin flows underneath and the process repeats.

  • Fine detail and smooth surfaces for models, prototypes and selected functional parts.
  • Whole-layer exposure makes it practical to print several parts together on the build plate.

Typical uses. Product design, detailed models, prototypes and engineering parts in the right resin.

Industrial SLA · stereolithography

Large-format resin printing for industrial applications

A laser above a vat of liquid resin traces and solidifies each layer. The build platform lowers into the vat and a fresh layer of resin is spread for the next scan.

  • Large build volumes take substantial parts in one piece, or batches of smaller components.
  • Smooth surfaces and an established industrial resin range suit prototypes, patterns and tooling.

Typical uses. Automotive prototypes, large housings, master patterns, display models and tooling.

SLM · selective laser melting

Manufacture complex parts directly in metal

A form of laser powder bed fusion. A recoater spreads a thin layer of metal powder, lasers melt the selected areas and fuse them to the layer below, then the platform lowers and the process repeats, inside a controlled atmosphere.

  • Metal parts with complex shapes and internal features that can be hard to machine.
  • Several components built together, so suitable parts need no dedicated mould tooling.

Typical uses. Engineering components, metal tooling and parts with internal channels. Material and application are checked for each job.
