3D-printing, materials and colors
What to expect from 3D-printed parts?
Products made with 3D-printing may have small variations from part to part compared to for example CNC machined parts. This does not mean that parts with faults gets delivered to customers. The products can be washed with ordinary car / interior wash products. The parts also withstand being wiped with isopropanol.
FDM / FFF - Fused deposition modelling "Computer controlled glue-gun"
This is the traditional 3D-printing method where one layer of plastic gets "glued" on top of the previous layer. Big parts can be made. This methods weakness is lower layer adhesion compared to other methods, but this weakness can in most cases be avoided with good designed parts.
- PC (Polycarbonate): is a impact resistance plastic used for making products that has to withstand high wear and temperatures over 100° C. This is a excellent material for parts installed in the engine bay.
- PLA (Polylactic acid or polylactide): is a brittle bioplastic and is often used for prototyping and manufacturing of products that do not have to withstand high stresses or temperatures over 60° C.
- NinjaTek Armadillo: is a hard rubber with a shore Hardness = 75D. This filament does have a higher abrasion resistance than standard filaments. Chemical resistance to many materials, including naphtha, ASTM Oils #1-3, petroleum and freon. Technical data Chemical Resistance
- NinjaTek Ninjaflex: is a very soft rubber with a shore Hardness = 85A. This filament can be used to for gaskets and very flexible parts. Based on polyurethane and does have a 660% elongation. Chemical resistant to many materials, including naphtha, ASTM Oils #1-3, petroleum and freon. Technical data Chemical Resistance
- PETG (Polyetylentereftalat-glykol): is a durable material that can withstand temperatures up to 85° C before deformation. This thermoplastic is suitable for interior parts and more.
- Dark grey
Please ask if you need any other color for your part.
SLA - "UV-cured resin"
This method uses UV-light to cure a liquid resin to make very detailed and small parts with good layer adhesion. The biggest weaknesses are smaller build volume and more expensive raw materials.
- 3D-printed with "tough" resin. Hard but flexible material. Can be used to make precise small parts that does not have to withstand high load. Technical data
SLS - Selective Laser Sintering
This process melts plastic with a laser beam in a bed with powder. This is an expensive machine with medium to good precision.
- PA2200 is good for flexible clips and can be made with thin wall thickness. Technical data
