Mars Accuracy

I’ve noticed that the prints on my own 3D printer are snug compared to the same parts printed by Shapeways. Indeed, the sand dome and the ash pan wanted a little scraping where they connect with other parts. So, I made a 2 cm test cube to see what I could learn about the accuracy. […]

It turns out that one of the benefits of having your own 3D printer is that you can afford to experiment a little bit. If a part doesn’t work out the way you thought it would, you can modify the drawing, export it, and try again. There is no 10-day wait, no shipping charges and […]

Mars sees its first action

For Father’s Day this year, my darling wife bought me an Elegoo Mars 3D printer. Well, summer being what it is, it has taken me a while to get it out of the box, but now that it is in action, I must say I am truly impressed. Now, I will confess that I have […]

Happy Father’s Day to Me!

However, the newer resin printers are producing such excellent results, and the cost of shipping from Shapeways is getting so userous, that I finally […]

Is this the material we’ve been waiting for?

Since my first article on the topic in RMC in March 2012, I’ve been occasionally experimenting with the service offered by Shapeways. I find it to be nothing […]

Joint bars at the limit of 3D printing

VanRail 2015 took up the whole weekend, and so, nothing much happened with Pembroke. I received a some test joint bars from Shapeways on the Friday. This made for some fun times as I handed them to people and made them guess what they were looking at. Packed together to minimize material usage, they look […]

My friend, colleague and fellow creator, Mitch, bought a LulzBot 3D printer last week. I believe I’ve agreed to buy a share of it, and now might be the time.
