The Quickstone Challenge


download

It’s been some time since I posted a new Seej model. I got tied up with work for couple of months and then I got on to making Magic: The Gathering Tokens, and new Seej work kind of fell by the wayside.

Plus I’ve been working on getting the Forge going, and the Scrying Pool, and I’ve been dusting off my long-unused PHP chops, and also managed to develop cubital tunnel syndrome in my left arm to match the carpal tunnel in my right.

So here’s a quickie as I dip my toes back into the moat. I’ve designed the Quickstone bloxen with paper-thin walls and internal supports to print as rapidly as possible.

Look at the red bloxen in the photo above and you’ll see the backlit mortises self-inverting to become tenons.

My best print time on a Replicator 1 with default firmware and ReplicatorG is 27 minutes.

There have got to be übernerds out there with pimped out RepRaps who can smoke that. I’m particularly interested to see how quickly someone with a b9Creator, Form1, or mUVe can do it. The internal supports on the Quickstone are built for the limitations of an FDM printer, but could probably be deleted if you didn’t have to worry so much about gravity during the printing process.

Can you knock Lao Zheng off the mountain?

First, visit The Forge and download the Quickstone bloxen. (It’s buried under Forge -> Seej Models -> Fortifications.) Then email me with the deets on your slicer, your printer, and your results. Pics or it didn’t happen.

Here are the settings I used:

Replicator1 Dual (using single head)
Infill: 0%
Layer Height: .3mm
Shells: 1
Feedrate: 75 mm/s
Travel Feedrate: 75mm/s
Print Temperature: 240°C
HBP Temp: 110°C
ABS Natural

A few rules:

  • We’re on the honor system here. No fibbing.
  • Cram as many 1:1 bloxen into your build area as you like, and measure your time in bloxen per minute.
  • Slicing time is not included in your total.
  • The bloxen must print in one piece.
  • The bloxen must be usable in a Seej match. If it can’t withstand a firm squeeze, it’s no good.
  • you can modify the bloxen’s geometry, but under the terms of the CC license you must make derivatives available to others. I can host your model in The Forge, or I’ll link to the site of your choice.

Have at thee!

    Unlike FDM and laser based SLA, the B9Creator forms the entire layer simultaneously. So build time is purely a function of object height. At about 18 mm per hour, it may not seem particularly fast. BUT, depending upon the size of those blocks, we may be able to fit 4-6 in our build area. Time to print those would be the same as the time req. to print one. (And they could all be solid, if desired.)

      Wow, so a solid bloxen prints at the same speed as a hollow one? Cool.

      Would the hollow volume present a problem for the B9Creator? Would there be liquid resin stuck inside?

      Thanks for stopping by, Mike! I’d love to see your results if you get around to printing one of these.

      I updated the rules so that we can get as much of an apples-to-apples comparison among different styles of printers as possible.
