Determinants for choosing the 3D printer
- Resultant model kind
- Tools used
- Total cost
Selection criteria as said by Mark Tyrtania, Sales Director of Laser Lines:
- Privileges of the material used
- How much a technology is capable of meeting your desired product features
- The reliability, longevity, flexibility of the model manufactured, and how well an object copes up with it 3D designed image.
- And last of all, after choosing the 3D printing technology, either FDM or Polyjet 3D printing, choose the printing device that does not put much economic restraint on you.
Comparing Fused Deposition Modeling and Polyjet Technology in various aspects
Retaining Exactness and Longevity
Models created via FDM technology are more firm in their existence, whereas those created by Polyjet have been observed to develop altered shape over time occasionally. Depending on the material used by the FDM 3D printer, the models manufactured are more capable to combat the extremes of temperatures with a longer functional life span.
You cannot expect production of very smooth models with FDM printers. Layer of 3D models these printers produce are often visible separately as these layers don’t have as less thickness as those produced by Polyjet 3D printing. If you want models with fine curves, slopes and gradients with flexible yet strong properties, then go for Polyjet. FDM uses materials having highly demanding properties.
The fine details of model layers achieved via Polyjet is obtainable due to the use of liquid photopolymer spurs that are solidified to form a model layer by layer with the help of ultra-violet rays integrated in these printers via the UV lamps. Therefore these printers are more desirable for attractive finished goods required for consumer needs and electric parts.
The material options
The consistency and color and the healthy properties of a model depends on the material used. Whether a model is rigid or flexible, all depends on the kind of material used for a certain 3D printing technology. The polyjet is more impressive as it is accompanied by thousands of material options with the privilege of using a mixture of several material, which makes this printer highly recommendable. Therefore, you can easily obtain the model of desired consistency and texture with Polyjet printers.
The new addition of the famous J750 in the Polyjet series has the capacity of loading six materials at a time for creating the required product. This material mixing enables production of fully transparent model parts via the Polyjet printers. All the finished models of Polyjet printing can be measured on a wide flexibility scale ranging from a flexible gasket to a strong and rigid car tire.
