Chipboard vs. 3D Printing: Choosing the Right Medium for Student Models

Every architecture student eventually faces the same late-night decision: Do I keep cutting chipboard, or should I try to 3D print this model?

I’ve been on both sides. In school, most of us lived with stacks of chipboard sheets, dull X-Acto blades, and spray-mount fumes. It was fast, cheap, and flexible — but also messy, inconsistent, and fragile. Later, once I had 3D printers in the shop, I saw the other side: clean volumes, perfect repetition, and the ability to capture forms you simply couldn’t cut by hand.

Neither option is “better” in every case. The trick is knowing which tool to reach for when.

The Case for Chipboard

Chipboard is still the most common modeling material for students — and for good reason:

• Speed with simple geometry: For massing blocks or quick iterations, nothing beats grabbing a knife and cutting by hand.

• Low cost: A few dollars gets you enough material for an entire site model.

• Flexibility: Easy to cut, layer, and glue; no need for digital prep or machine access.

• Studio culture: Professors are used to seeing chipboard — it’s familiar, and it communicates ideas quickly.

Limitations:Chipboard struggles with precision. Edges fray, measurements drift, and repeated elements (columns, trusses) rarely look identical. Models often warp or collapse when handled, and by the second critique, they rarely look fresh.

The Case for 3D Printing

3D printing flips the trade-offs:

• Precision + consistency: Every column, mullion, or façade element is identical, something chipboard rarely delivers.

• Complex geometry: Parametric surfaces, curves, and undercuts are possible.

• Durability: PLA and PETG models travel better — no bent corners in your backpack.

• Time shift: Instead of spending hours cutting, you prep a file and let the printer run overnight.

Limitations: 3D printing isn’t instant. Files must be prepped carefully, printers can fail and build volumes limit size. Costs are higher than chipboard, especially for large site models. And sometimes, waiting 8 hours for a print when you could have cut chipboard in 30 minutes isn’t worth it.

A Student Story

One student came to us with a final review just three days away. Their model included a complex roof grid and large building volume. Cutting in chipboard would have been exhausting and inconsistent, but the clock was ticking.

We translated their Rhino file into printable STL components, optimized for FDM printing, and batched the pieces overnight. By morning, the student had a clean set of PLA volumes ready to assemble. At critique, the sharp, uniform details stood out, and the student said the model “changed the way the room responded.”

That project showed the sweet spot of 3D printing: when precision and repetition matter more than raw speed.

So Which Should You Choose?

Think about:

• Speed vs. precision – Do you need something tonight for a desk crit, or a model that will survive a jury panel?

• Complexity – Is the geometry simple enough to cut, or are you working with forms that beg for digital fabrication?

• Budget – Chipboard is cheaper; 3D printing adds cost but saves hours.

• Durability – Will the model need to travel, be re-used, or displayed beyond one crit?

Our Take at BDR DSG LAB

We don’t see chipboard and 3D printing as opposites — we see them as partners. Many of the best models combine both: a chipboard site base with 3D-printed buildings, or hand-cut massing volumes with resin façade panels. The right balance depends on time, budget, and the story you need the model to tell.
