3dnextechAn Italian innovative startup has its headquarters in Livorno, Tuscany. He was born as a fallout from the Sant’anna School of Advanced Studies in Pisa.
When experimenting with 3D printing, plastic parts often need a lot of additional attention to increase their strength and appearance. This could mean anything, sanding to the addition of resins or primers improving component performance before assembly or final use. However, these manual processes have a significant cost for companies and do not always solve the problem completely, while coherent quality is embarrassing to achieve. These challenges were the main obstacles to the generalized 3D printing use for mass production, until today.
What is this
3DFINISHER technology by 3DNEXTECH is an intelligent solution which in this context offers interesting advantages for businesses and individuals. It consists of a plug-and-play device adapted to 3D printing Equipment that does not require additional infrastructure such as hoods. Once installed and configured, the device induces a patented physical chemical process which transforms the morphology of the surface thanks to the values of tailor -made temperature, depending on the type of plastic.
In particular and in relation to other treatments, this smoothing technique has the advantage of maintaining the solvent throughout the process in gaseous form. This means that plastic material inside the room is never in contact with liquids or droplets that could cause unwanted local surface defects or porosity.
Properties
The transformation process lasts between 1 and 2 hours, depending on the material and size of the plastic parts. Indeed, plastic molecules on the surface need time to disentangle and reorganize in the favorite and aligned orientation. The resulting object, alongside having an extremely smoothed surface, becomes waterproof, resistant to dirt, painted and easier to metalize. It can also present improvements in its mechanical properties, such as tensile resistance, which means an increase in the load of tensile breaking, its hardness and its resistance to the impact.
Applications
The system is currently compatible with ABS, ASA, PETG and acetate cellulose parts. Future developments focus on nylon and composite materials. The original manufacturing process is not decisive: it may be a filament deposit, SLS or even traditional processes such as those used to make cadres of cellulose acetate glasses (cut and bending from leaves). Machines currently have a maximum capacity of 30x30x30 cm.
Overall, 3DFINISHER technology Developed by 3dnextech could change the situation in the world of design and manufacturing. With its ability to easily refine complex geometries, its wide range of materialsAnd its cost savings potential, it helps develop new ideas and certainly supports creativity in the inspiring but stimulating benchmark for additive manufacturing.
