3D printing with Nylon

Just how flexible are your 3D prints?

The usual run of things with 3D printers is to spit out parts in good old ABS or similar plastics that have a low melting point. Just imagine the world of opportunities that opens up when you can print in flexible – and tremendously fun – Nylon 6?!?

Requiring slightly higher temperatures for extrusion than the more common rigid (but brittle) ABS or PLA, nylon’s slick bendable qualities lend themselves to all kinds of new possibilities. Gears and bearings created from nylon have the advantage of not requiring lubrication and there is also scope for flexible tubes and parts with undercuts such as lids, plugs and phone cases.

“We can literally change the hardness/firmness/tensile strength of a part by changing it’s fill percentage. Want a small keyboard button overlay for a control box…..fill at 25%….want a bearing that has a bit of give to reduce vibration…..fill at 50%…want a hard almost UN-bendable lever….fill at 100% and so on.”

The following video shows some of these capabilities as printed in nylon.

Missed out on the CNC Shapeoko mill?

Want your own open source CNC mill?

If you’ve so far missed out getting your hands on the opensource kickstarted Shapeoko CNC mill there is some hope – Inventables who’re now the distributors are accepting pre orders for their next batch of 100 units. Demand for the ShapeOko has been high since their Kickstarter campaign. Depending on how keen you are to source some of your own components – there are several prices ranging from the basic mechanical kitset at $199 to the fully featured premium option at $999 that also comes with router cutters and materials.

Designing for San Francisco

SF Bay Area – a Design Inspiration for little and big thingsWe’re used to seeing locations and landmarks serving as inspiration for design and art around us. Think how much influence the Eiffel Tower, for example, or anything NY has had on so much of the styling we are exposed to. As a designer you may be particularly influenced by design styles of places you’ve travelled to or your own city that you commute through every day. One US designer has chosen his place of residence – San Francisco as a catalyst for his creative endeavours.

David Nichols of Dotmatrix Design takes major inspiration from various infrastructure and industry around the Bay Area. Conveniently located in same area, Ponoko has helped shape his creative process. David’s first project was a human scale model of SF Sutro Tower, “a local landmark TV tower that pokes through the fog of the city most days of the year”. He had the tower CNC routed out of plywood, and it will be making its way to Maker Faire next month as part of the Ponoko display.

David likes the challenge of using interlocking to produce 3D objects out of 2D shapes, so laser cutting and CNC routing are his ideal precision fabrication methods. He’d made a tiny model of the container cranes in the Port of Oakland and also laser cut maps of the Bay Area. Most of the objects he created are fabricated out of wood, either in plywood or composite form. Hardboard and MDF are some of David’s favourite materials to work with. The material choices allow for minimal finishing and easy assembly that doesn’t require adhesives.A few words from the designer after the jump:

StippleGen converts any image into CNC-friendly SVG format

Time to go dotty with your CNC artwork

Halftone-styled images have a compelling power to them. Perhaps it’s the retro-nostalgia of 1960’s Pop Art, the grainy speckles of old newsprint, or maybe it’s something else entirely? Either way, there is just something about all those dots.

Evil Mad Scientists (you know, the guys behind the Egg-Bot amongst other things) have released StippleGen, a stand-alone program that converts any image into CNC-friendly SVG format.

There is a considerable amount of control as you tweak the algorithms, whether you are after a specific number or style of dots, or even a continuous TSP path. It’s all geared towards use on small CNC devices such as the Egg-Bot, but don’t let that stop you if you have larger aspirations.

StippleGen is designed to be easy to install, easy to use, and easy to modify. It is capable of producing excellent quality output with up to 10,000 points.

Click through to EMSL for a thorough run-down on just what this neat little software package is capable of.

Parametric voronoi bookshelf

An experiment in interactive generative design

Voronoi shelf

Inspired by the likes of Nervous System, Alan Rorie of Hero Design has created a generative software bookshelf application with Processing based on the voronoi pattern algorithm. The software allows users to determine variables such as overall size, shape and depth and then automatically generates the appropriate 3D geometry which can also be flattened and saved as a PDF in 2D for cutting out via the selected production process i.e. laser/waterjet cutting or CNC routing.generative (more…)

Introducing the ShapeOko 3D printer/CNC kit!

The $300 open hardware CNC machine is here. And it’s also a 3D printer!

Last summer, Edward Ford announced a Kickstarter campaign to support a project he had been coming back to for years: the most affordable desktop CNC machine ever, completely open hardware.

Edward’s project was over 700% funded, and he immediately set out improving his initial design. He also set up ShapeOko.com, and blogged about his progress along the way.

It’s been 8 months of late-nights in the garage, community feedback, sourcing woes, and huge support. And a few weeks ago the first batch of ShapeOko kits shipped out to his Kickstarter supporters.

ShapeOko looks a lot different these days than the previous laser-cut MDF machine holding a ballpoint pen. : )

It now features extruded aluminum rails from MakerSlide, custom laser-cut steel plates, and an 8″x8″ cutting area with a Z axis height of 3.5″
