Prototyping A Camera Mount

Prototyping A Camera Mount

3D printing makes it incredibly easy to crank out new parts on a whim. For example, I’m about to make the trek to California for RoboGames and want to use a Contour ROAM2 HD action camera to capture some of the action – especially ComBots with the massive steel robots trying to inflict mortal damage [...]

MakerBot Announces New Scanner

MakerBot Announces New Scanner

It’s SXSW  time again already, so it should come as no surprise that companies involved in the interactive space are rolling out press releases and product announcements designed to leverage the excitement of the moment. The most exciting, and interesting announcement that we’ve seen so far came from Makerbot on Friday. The company’s CEO, and [...]

Using MakerWare Software with Older Makerbot Printers (Video)

Using MakerWare Software with Older Makerbot Printers (Video)

It didn’t take long for Josef Prusa to figure out how to hack the new MakerWare software from MakerBot so that it could be used with earlier Makerbot printers like the Cupcake and Thing-o-matic. Surprisingly, Makerbot didn’t provide this functionality, at least not with the initial release of MakerWare. They seem to have left their [...]

Almost Perfect Parts, but…

Almost Perfect Parts, but…

I’ve been able to fine tuning my tool chain and Tantillus printer to the point that parts come off the printer looking almost perfect. The dimensions are close to spot-on, though my first layer is still a bit squashed. The surface finish when I print PLA with 150 micron layers looks almost like satin. Therein [...]

Adding Focused Lighting to a Tantillus RepRap Printer

Adding Focused Lighting to a Tantillus RepRap Printer

Like many RepRap printers with an enclosure, the build platform on my Tantillus is a bit dark for photos and capturing good quality video. At the same time, I don’t like the gaudy mass LED football stadium lighting that a lot of builders stick on their printers. If possible, I want more controlled and focused [...]

New 3-Way Extruder Design Yields Multi-color 3D Printed Parts

New 3-Way Extruder Design Yields Multi-color 3D Printed Parts

3-D printing is fantastic but one of limitations we run into all the time is the limited selection of colors of filament to print with. It would be fantastic to print with multiple colors in the same part. The MakerBot Replicator has done this using a two extruder head design. Their approach is fine however [...]

Why Cleaning Up After Yourself Is Good Practice….

Why Cleaning Up After Yourself Is Good Practice….

When you’re printing plastic it’s really easy to quickly end up with lots of small bits and pieces of stray plastic all over the place. This is especially true in the bed area where you’re extruding plastic, getting stringers (hopefully not too many or too often), etc. Normally they don’t cause any problems and are [...]

Accessing Thingiverse RSS Feeds

Accessing Thingiverse RSS Feeds

Thingiverse, the design sharing site, is pretty amazing but is still in its infancy as far as being user friendly and feature rich. One of the features that it is currently missing is the ability to follow Thingiverse users as they upload new designs or print new parts. There are quite a few friends and [...]

Fraser Valley RepRap Group Meet-up Photoset

Fraser Valley RepRap Group Meet-up Photoset

Early in July I had the great pleasure of attending a meet-up of the Fraser Valley RepRap Group near Vancouver British Columbia. The group has close to 60 active members and is doing some really creative work. Here are some of the photos from my afternoon with this great, and very open/welcoming, group of RepRap [...]

Reprap 3D Printing – Are High Travel Speeds Useful?

Reprap 3D Printing – Are High Travel Speeds Useful?

One of the major ‘learnings’ that came out of this trip was an increased respect for logic and analysis. A good example was when Billy Zelsnack, the creator of the Printxel 3D printer showed me how easy it is to analyze different printing options using KISSlicer. We were discussing unexpected print head crashes – typically [...]
