High-Speed 3D Printing of Wireframe Prototypes

Detailed Technology Description
WirePrint: 3D Printing of Wireframe Models using Commercial PrintersOn-The-Fly Print: Enhanced 5-Degrees of Freedom Wireframe 3D Printer and Software  Our recently developed wireframe3D printing system can be implemented for both traditional 3D printers (WirePrint Software) as well as with ourenhanced printer setup having 5 degrees of freedom (On-The-Fly Print Software and Printer). High speed prototyping canbe accomplished ~10x faster using WirePrintand off the shelf printers. For applications where ultra-high throughputprototyping is needed, On-The-Fly Print Software can boost throughput byover 30x using our 5DOF based printer enhancements and custom algorithms.

*Abstract
WirePrint: TechnologyOverview

WirePrint software was developed for generating and printinglow fidelity 3D wireframe previews of designed objects -- to scale and at highspeed. The software is usable with most consumer-level 3D printers and allowslow-cost and high-speed production of work-in-progress prototypes.

 

The filament is extruded directly into3D space as opposed to traditional layer-by-layer application. Thisapproach allows the edges of the wireframe model to be created directly, onestroke at a time, resulting in speeds up to ten times faster than traditionallayer-based printing. 3D prototypes can be produced in minutes rather thanhours, allowing designers to quickly see the practical results of minutechanges or additions, minimizing the cost of changes in design. As an example,a bottle that would typically take about two hours with regular printingsoftware, was printed in 14 minutes with WirePrint.Our software can easily transform a regular, solid design STL file into a meshstructure for rapid prototyping.

 

 

On-The-Fly Print: Technology Overview

As an additionalstep up in speed and capabilities, we offer “On-The-Fly Print”. Cornell researchers developed a new printingsystem and software that takes advantage of a custom printer modificationallowing for 5 degrees of freedom (5DOF).With two additional rotation axes, the edges of an object can be approached bythe printer head from any direction, speeding up the print process and enablingprinting of more versatile designs. This is combined with custom algorithms to generate a printing plan that guarantees a smooth,collision free printing process.

 

In addition, theCornell On-the-Fly 3D printingsystem allows the user to begin printingduring the design phase as well as modify an object in real time. The software can start printing features asthey are created digitally, a cuttingtool enables automated removal/deletion of already printed parts. If a userwants to measure or examine a printed object, they can pause the printingprocess and remove the object from the printer. After examination, the objectcan be replaced and the software will continue printing where it left off.
