# Polished 3D-Printing Techniques Printoptical's Printing Technology Requires No Post-Processing By Laura McQuarrie | Published 2016-10-22 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/printing-technology References: [3dprinting](http://3dprinting.com/lighting/smooth-3d-printing-no-post-processing-required-with-printoptical-technology/) & [luxexcel](https://www.luxexcel.com/optics-prototyping/) As it stands, most [3D printing technology](https://www.trendhunter.com/trends/heygears1) requires post-processing, which involves the sanding and painting of an object after it has been manufactured. Luxexcel’s Printoptical Technology offers a way to print entirely smooth surfaces from the get-go, entirely eliminating the need for any post-processing or refining. The technology uses droplets of ink that merge and flow before being cured with UV. As a result, this manufacturing system is ideal for the creation of [transparent and completely smooth products](https://www.trendhunter.com/trends/eufymake-uv-printer-e1). The quality of the products its system can create leads Luxexcel to say that its Printoptical Technology is ideal for optics design. While [additive manufacturing](https://www.trendhunter.com/trends/3dprinting-resin) is extremely advantageous for creating rapid prototypes, when a refined finished product is needed, Printoptical Technology is unparalleled. ## Trend Insights (Trend Hunter) - Score: 3.6/10 - Popularity: 24% | Activity: 76% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### Why This Trend Is Growing - **Post-processing-free 3D Printing:** Printoptical's technology enables completely smooth surfaces without the need for post-processing, disrupting traditional 3D printing. - **Transparent 3D Printing:** Luxexcel's Printoptical Technology makes the creation of transparent products possible, offering opportunities for innovative products. - **Optics Design with 3D Printing:** Printoptical Technology allows for the creation of high-quality products, making it ideal for optics design and potentially disrupting traditional manufacturing processes. ### Industries Being Reshaped - **Manufacturing Industry:** Post-processing-free 3D printing technology can revolutionize traditional manufacturing processes. - **Optics Industry:** Luxexcel's Printoptical Technology can offer innovative solutions for the optics industry and challenge traditional manufacturing processes. - **Product Design Industry:** Transparent 3D printing technology creates opportunities for innovative product designs, disrupting traditional manufacturing and design processes. ## Related on Trend Hunter - [3D Glass Printing Methods](https://www.trendhunter.com/trends/complex-glass-structures.md) - [Digital Glass Design Breakthroughs](https://www.trendhunter.com/trends/g3dp-2.md) - [Consumer Desktop Vapor Smoothers](https://www.trendhunter.com/trends/postpro-sf2x.md) - [Advanced 3D Printing Solutions](https://www.trendhunter.com/trends/hp-multijet.md) - [3D Glass Printers](https://www.trendhunter.com/trends/nobula.md) - [Efficient 3D Printing Systems](https://www.trendhunter.com/trends/color-3d-printers.md) - [Industrial-Grade 3D Printers](https://www.trendhunter.com/trends/lcd-3d-printer.md) - [Light Source Resin Printers](https://www.trendhunter.com/trends/halot-ray.md) - [Automated Resin-Removing Printers](https://www.trendhunter.com/trends/stratasys-neo800-plus.md)
