3D Printing
& Scale Modelling
From rapid prototypes to detailed scale models, we transform concepts into accurate physical models using advanced 3D printing technologies and a wide range of materials.
Scale Model
Materials Used
A versatile range of materials can be selected based on the required appearance, application, strength and model characteristics.
FDM Technology
FDM – Fused Deposition Modelling
In FDM, a strand of material, in this case thermoplastics, is deposited in layers to create a 3D printed object. During printing, the plastic filament is fed through a hot extruder where the plastic gets soft enough that it can be precisely placed by the print head. The melted filament is then deposited layer by layer in the print area to build the work piece.
FDM Uses
SLA Technology
SLA – Stereolithographic Apparatus
SLA is the abbreviation for Stereolithographic Apparatus, or simply stereolithographic. Like FDM, SLA is an additive method where models are built layer by layer. SLA, however, uses a curable photopolymer, typically a liquid resin, that is hardened by applying focused light or UV light. This process is called curing. SLA printers usually build the models from top to bottom, while the build platform lifts the model upwards out of the resin bath.
Laser & DLP Technology
The light source is either a laser or a digital projector. The technology is often called DLP – Digital Light Processing. Lasers draw individual layers, while in DLP an entire two-dimensional layer of the model is projected at once into the resin bath.
Printing Performance
Laser SLA printers are usually slower than DLP models because of the smaller surface of the laser beam. DLP printers can harden each layer faster because the entire image is projected onto the resin at once.
Maintenance
DLP projectors are generally more reliable and easier to maintain than customized laser systems, as they use technology similar to business and home cinema projectors.
Post Processing
Printed models require a post-processing stage. SLA machines are generally more professional focused, although resin printer prices have reduced significantly in recent years.
