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 [...]

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 [...]

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 [...]

Mapping Out An Approach to 3D Printing

Mapping Out An Approach to 3D Printing

One thing that is abundantly clear after my 10 day RepRap U.S. tour is that the 3D printing problem involves a large number of interdependent variables. There is no obvious simple solution, at least not one that is obvious to me at this early stage. Variables like filament plasticity and makeup, filament diameter, a whole [...]

Shrinking the Design Process Using 3D Printing/RepRap

Shrinking the Design Process Using 3D Printing/RepRap

[Flash Snoot - test print at approximately 10% completion.] One of the primary advantages of affordable, accessible 3D printing like RepRap is the way that it facilitates the design process. The ability to imagine a new part or product then quickly prototype the concept and hold the actual part in your hand within an hour [...]

The Right Tool for the Job

The Right Tool for the Job

Before I started actually printing with Tantillus I spend uncounted hours/days/weeks devouring everything online about Reprap and 3D printing. That was extremely helpful, but also generated a little fear and trepidation. One of the things that I heard about frequently was the problem that many people had in getting their parts to stick to the [...]

Learning From Other People’s Failures

Learning From Other People’s Failures

One of the major factors that differentiates mankind from other animals on the planet is our ability to capture and share knowledge. And, the most important knowledge that needs to be preserved and proliferated is our failures. We learn much more from failing than we do when we succeed. That’s especially true in emerging fields [...]
