Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Dual extrusion and multi-material 3D printing are the same thing. | Dual extrusion and multi-material 3D printing are not the same thing. Dual extrusion refers to a printer with two separate print heads that can print with different materials or colors, while multi-material printing involves using a single print head to mix multiple materials together during the printing process. |
| Multi-material 3D printers are more advanced than dual extrusion printers. | This is not necessarily true as both types of printers have their own advantages and disadvantages depending on the specific application. Multi-material printers may be better for creating complex geometries or parts with varying material properties, while dual extrusion printers may be better for producing parts with multiple colors or support structures made from a different material than the main part. |
| All 3D printers can do dual extrusion or multi-material printing. | Not all 3D printers have the capability for dual extrusion or multi-material printing as it requires additional hardware such as an extra print head or mixing chamber, which some lower-end models may not have. It’s important to check if a printer has this feature before purchasing it if you plan on doing these types of prints. |
| Dual Extruder Printers Are More Expensive Than Single Extruder Printers. | While it’s true that dual-extruder machines tend to cost more upfront than single-extruder ones, they can save money in other ways by reducing waste (since they allow you to use dissolvable supports) and increasing efficiency (by allowing you to switch between filaments without having to manually swap them out). Additionally, prices vary widely based on factors like build volume, resolution capabilities, etc., so there isn’t always a clear-cut answer when comparing costs between different models/brands. |
