TECH HELMET UPDATE

SANDED AND IVE STARTED PAINTING

DID I PROPERLY PRIME IT?

NO!

CAN YOU SEE THE SEAMS WHERE I GLUED IT IN SOME PLACES?

YES!!

IS THE CLAY PERFECT?

NO!

but its is actually so fun and I love it sm!!

3D printing as easy as 2D printing

3D printing as easy as 2D printing

“We invent software that will revolutionize the 3D printing for everyone. We can optimize the processes so far, that they are so simple, as in today’s home-2D printing. We will create the MS Word for 3D printing!”, 2015-09-20 Ernst Christian Fleischmann

Printing Speed

When discussing printing speed, 2D printers have a metric used in marketing: pages per minute (ppm). Printers with high ppms imply that users will spend less time waiting for their documents and, therefore, the printer is better than those with low ppms. Companies achieve higher ppms by using minimalistic, custom documents at low quality settings. Missing in the calculation are the printing overhead (how long it takes the printer to warm up, for example) and how long it takes printers to print documents that resemble their customers’ documents.

In contrast, 2D laser printers have a more rigorous benchmark for the number of pages that can be printed with a single toner cartridge defined in ISO/IEC 19752. The test procedure includes a PDF test document and constraints on the printing environment in addition to specifying how many cartridges need to be tested. Together, the results have a better chance of producing meaningful comparisons between cartridges.

Currently, consumer 3D printing lacks either a marketing-based or a controlled, data-oriented benchmark to gauge printing speed. Reading that printing “a solid plastic apple…takes seven hours” to print, for example, doesn’t include the layer height or define what solid means (Does it refer to having a shell? A certain infill percentage?). Also unasked is how much, if any, post-print processing time is required.

As an example, we’ve been prototyping our new 3D printer using an existing, industrial-grade 3D printer while we continue to improve our own extrusion algorithms. Printing our ~22.4MiB parts together requires about 110 hours using 0.25mm for the layer height, the “high density” infill option, and “smart” support generation. After printing, removing the support material takes another 24 hours of soaking. This averages to about 16 hours per part of printing time. Without testing this on other printers, though, we don’t know how the printer we’re using compares to others—though we do know it’s faster and cheaper than machining each part or molds for each part.

The closest metrics we have are the “time to part” and “print speed” metrics. HP’s Vyomesh Joshi states the average time to part is more than eight hours. Like ppm, though, the options used and object printed to reach that number are unclear. Print speed refers to either the linear mm or m^3 volume of filament extruded per second; while valuable, this number doesn’t lend itself well to estimating how long it takes to print a Yoda bust or doll stand.

Developing a standard, relatable metric for 3D printing speed will help users choose between printers and help manufacturers improve their designs. If you’re aware of such work going on already, let us know; otherwise, it’s something we’ll be contributing to in the future.

Piccolo the tiny CNC-bot

Piccolo is a pocket-sized stand-alone CNC platform. For less than $70, you can assemble your personal Arduino-compatible kit for tinkering, developing and deploying basic 3D output. Be it plotting quick graffiti, printing a one-off business card on the fly, or multiple Piccolos working together to create a large mural, this kit provides a platform for experimenting with 2D or 3D digital fabrication at a small scale. This open-source design emphasizes simplicity, and is entirely composed of digitally manufactured components and inexpensive off-the-shelf hardware. piccolo.cc by: Cheng Xu | cheeriocheng.com Huaishu Peng | huaishu.me Tiago Rorke | tiago.co.nz Greg Saul | gregsaul.co.uk
