Generation of physical parts
3D printing allows you to generate a physical piece from a 3D drawing.
It is an ideal technique to make prototypes, models (especially in dentistry), or even manufacturing small production runs.
It have to keep in mind that each piece demands a different precision. For example, in the case of dental models, as well as definitive prototypes, high precision is required. In other cases, for example, in prototypes of first designs (those that are used only to see if the design is well focused), the precision is not so important, in these cases what is most interesting is economical cost.
Also, on some occasions, the need may arise to produce a small run of pieces of which there is no mould and to manufacture that mould can be expensive for what is intended to be produced.
So, in order to respond the diverse needs of our customers, we offer three 3D printing services according to the system used: liquid resin, sintered, and fused filament fabrication (FFF).
Liquid resin technology
3D printing using the liquid resin technology allows to provide fine and precise finishes. It can be very useful to make dental models, final prototypes and small runs of pieces.
It consists of giving a 3D drawing a physical format through the contribution of liquid resin (photopolymer). Once the resin is deposited, it is cured instantly with UV light. The resin contribution is layered, which can be 0.016 mm (16 microns) or 0.028 mm (28 microns) thick. According that we have two types of finished:
- High precision finished for technical parts, with a tolerance of ± 0.05 mm.
- Standard precision finished for parts that do not demand high precision finish but of good precision, with a tolerance of ± 0.10 mm.
The materials can be hard, rigid and semi-rigid, transparent, with high thermal resistance, with elongation at the breaking point, rubbers, with properties similar to those of PP, HDPE, PMMA, PC, ABS, HIPS, TPE-S and EPDM rubber.
3D printing using the sintering system is transforming a 3D drawing into a solid piece by polymerizing of polyamide (PA) powder. In this case, generating layers 0.08 mm thick. It allows to produce precise, functional and quality pieces.
Very useful for prototyping as well as small production runs.
Fused filament fabrication (FFF)
Basing on the 3D drawing, 3D printing fused filament fabrication (FFF) system builds the piece through the contribution of hot plastic filament that is deposited in layers with a thickness that can range from 0.9 mm to 5.4 mm
It can be very useful when it is necessary to perform …
… large format prototypes and muckups for big pieces, from packaging design to interior design pieces. The machine has a work area of 500 mm x 500 mm with a height of 500 mm
… economic prototypes for early stages of projects
