So, I’ve been writing lately about my new class that I’m developing for next year called Make Writing. I’ve been writing curriculum for this class that leverages 3D printing in order to teach Literacy and Writing. The class itself is made up of many of our students who have, up until now, been detached from more traditional education. They are the ones at risk for dropping out. They are the ones being left behind by life. My school, however, wants to attack their disengagement in a different way, and that’s where this class comes in. We’re hoping that the Making aspect of this class helps to make learning more meaningful, more hands-on, and overall, more engaging. After all, student engagement is the key. As Kelly Gallagher says, Engagement first, then Content, then Rigor.
I’ve also written about the challenges of learning 3D printing myself. You see, I’m leveraging my own ignorance as a model of how to learn, and the kids are finding that I learn this tech far slower than they do. But while the hardware is out of my wheelhouse, Language Arts is not. So I’ve begun developing the lessons that will become our benchmark writing assignments, ongoing journal prompts, as well as informal and formal assessments for the next school year.
The Argh Wall! is one of the first writing lessons I conceived for the class. It embraces the failures that come with 3D printing as well as the failures that sometimes come with the writing process. After all, if you think of writing as tinkering, then failure is just another way of saying “feedback prior to revision.”
Here is the lesson, the standards it hits based on 8th-grade Literacy and Writing, and a student sample to help you model for your students. I picture it as an ongoing assignment that students contribute to as failures happen. It’s a wall of student work that rotates depending on the projects that are under way and the progress that’s being made on any given piece of work. It’s a way for them to reflect, plan a next strategy of attack, and be assessed on constructed response writing. You can also access the file to make your own copy at www.tinyurl.com/ArghWall.

As students work using 3D printing, it is not uncommon to fail. With each failure, however, students should be encouraged to look at the steps it took to create the print, note what worked, and propose tweaks to the process before getting back up again.
Students will create a constructed response outline that shares information about their specific print, talks about their goal, and honestly shares what went wrong. For the purpose of this assignment, students are permitted to use appropriate voice to vent their frustration. They are also encouraged to use the vocabulary specific to 3D modeling and printing (extruder, nozzle, retraction, build-plate, bed, etc…)
Finally, the student should end on 1-3 bullets to propose next steps.
This Pyramid of Giza was a failed print, but a successful lesson learned. Not only did the painter’s tape warp immediately, but it was obvious from the start that this was going to affect the entire build. As you can see from the picture, the letters got squished and the layers didn’t flatten properly. I didn’t waste time shutting it down so that it didn’t waste filament or time. It was yet another failed print using blue ABS filament, and I wonder if that dye has something to do with the layers not “stacking” right. My next steps to solve this problem (I hope):
CCSS.ELA-LITERACY.RL.8.1 – Cite the textual evidence that most strongly supports an analysis of what the text says explicitly as well as inferences drawn from the text.
CCSS.ELA-LITERACY.W.8.2 – Write informative/explanatory texts to examine a topic and convey ideas, concepts, and information through the selection, organization, and analysis of relevant content.
CCSS.ELA-LITERACY.W.8.2.A -Introduce a topic clearly, previewing what is to follow; organize ideas, concepts, and information into broader categories; include formatting (e.g., headings), graphics (e.g., charts, tables), and multimedia when useful to aiding comprehension.
CCSS.ELA-LITERACY.W.8.2.B – Develop the topic with relevant, well-chosen facts, definitions, concrete details, quotations, or other information and examples.
CCSS.ELA-LITERACY.W.8.2.C – Use appropriate and varied transitions to create cohesion and clarify the relationships among ideas and concepts.
CCSS.ELA-LITERACY.W.8.2.D – Use precise language and domain-specific vocabulary to inform about or explain the topic.
CCSS.ELA-LITERACY.W.8.2.F – Provide a concluding statement or section that follows from and supports the information or explanation presented.
CCSS.ELA-LITERACY.W.8.10 – Write routinely over extended time frames (time for research, reflection, and revision) and shorter time frames (a single sitting or a day or two) for a range of discipline-specific tasks, purposes, and audiences.
You know, I’d expect these magical “voodoo” like printers to do an extraordinary job with making my invention, but when I first saw the print out, I didn’t see my invention in all its glory–instead, I got a flippin’ hairy box looking back at me. Unnecessary filament strings hanging everywhere. Come on, this ugly thing isn’t even mine! This print was supposed to be a 3D prototype for my invention (for the Invention Convention), but I can’t even use this. As a matter of fact, my invention is supposedly going to be manufactured with a 3D printer, but after seeing this, I’m very discouraged to do so. After doing some research, thank you very much, I found out that this was a problem that many printers have, known as “stringiness”. It seems to be caused by nozzles that move too slow and temperatures that are too hot. After seeing this, we attempted to change the nozzle temperature to 210 degrees and the build plate temperature to 70 degrees, but the results varied with different types of filament. For example, the red filament seemed to produce perfect results, but the blue and silver (especially silver) had not-so-great prints. Does this mean that the filament itself contributes to stringiness? Perhaps different colors call for different settings? Next, we decided to reprint my invention once more (with the red filament). The results did not meet to my expectation, but it was better than before. Still, there are strings…ARGH!!!! I suppose I could continue to tinker around with the printer’s settings to get a perfect print or I could simply use something else to make my 3D prototype.
The next attempts to solving this problem, as recommended by 3D Verkstan’s website, would be:
