We provide FFF/FDM 3D printing services. This technology consists of extrusion of thin strands of molten thermo-plastic and its deposition layer by layer until te whole part is printed. Under high temperature (200 – 250 °C) layers of material are joined together. In case of models with big overhangs, use of support structures is necessary.
FFF/FDM 3D printing is used for unit and small-lot production of the following products:
conceptual models and prototypes,
fixings, cases and other structural elements,
production tools and templates,
toys and gadgets,
decorations and many other.
In order to obtain desired object, we execute four basic steps of the process:
We offer 3D prints from the following materials: PLA, ABS, PETG and TPU.
1. PLA (polilactic acid) is the most popular material type used in 3D printing. Apart from 3D printing it is used for the production of food packaging and medical implants. It is biodegradable.
Things printed using PLA are strong and brittle.
PLA has low heat resistance. Leaving it in the car during a sunny day may end up in object’s deformation.
PLA has relatively low shrinkage and may be used for large 3D prints.
2. ABS (Acrylonitryle Butadiene Styrene) is used in the production of many different products, e. g. phone cases or tool hand grips.
Parts printed with ABS are strong and have high impact and scratch resistance.
ABS has good heat resistance (glass transition temperature is approx. 100 °C).
ABS has high shrinkage, therefore it’s not suitable for large prints.
3. PETG – glycol modified PET (Polyethylene terephthalate) used in the production of water bottles.
3D prints made with PETG are strong, have good impact resistance and moderate flexibility. They also have very good layer adhesion.
Good optical properties permit the use of PETG in the prints, which are to be translucent. The effect is very good in case of thin-walled objects. PETG prints have moderate gloss.
PETG has low shrinkage and may be used for large prints.
4. TPU (termoplastic polyurethane) and other flexible filaments, from which you can make e. g. bumpers, phone cases, belts and plugs.
Parts printed with flexible materials have good durability and abrasion resistance.
Flexibility makes TPU useful, where other materials aren’t suitable.
Flexible materials have good layer adhesion and moderate shrinkage.
In the table below you can find the summary of properties of the materials.
3D PRINTING PROCESS PARAMETERS
Below you can find information about basic parameters of our 3D printing process.
1. Layer height: 0,05 – 0,6 mm
The lower the layer height, the better the quality (less visible single layers of the print). On the other hand, the lower the layer height, the longer and more expensive is the print. If you don’t know what layer height is right for your print, rely on us. You can choose between three quality standards:
Precise (layer height from 0,06 to 0,1 mm) – by choosing this standard you indicate, that quality is most important for you.
Standard (layer height from 0,1 to 0,2 mm) – by choosing this standard you indicate, that you search for a reasonable comprimise between the quality and the price.
Economic (layer height above 0,2 mm) – by choosing this standard you indicate, that price is most important for you.
