EPS vs. Pellet Printing: What Does It Really Cost to Make a Large-Format Prop?
Scenography and prop studios have used EPS, fiberglass and foam for decades. These are familiar, reliable materials mastered by the team. But what do they actually cost? This guide breaks down the real numbers per project — including costs that rarely get calculated.
01 — Starting pointReference prop and methodology
To make the numbers comparable, all figures in this guide are based on the same reference prop: a stylized humanoid figure 1.8 meters tall, production run of 3 identical units. This is a representative piece for theater scenography studios, film prop houses and event fabrication workshops.
The three methods compared are:
| Method | EPS + finish | Fiberglass | FGF Printing (Fused Form) |
|---|---|---|---|
| Description | EPS block carved and covered with hardened fabric or resin | Base structure + fiberglass and polyester resin laminate | Direct 3D printing in HIPS or PETG pellet, surface finish applied after |
| Required equipment | Hand tools, heat cutter | Mandatory PPE, ventilation, molds | FGF printer (P600+ or P1000), slicing software |
| Learning curve | High (specialized sculptor) | High (experienced technician) | Medium (operator + 8h training) |
Methodology note: Material costs are 2025 reference ranges for Mexico, Colombia and the USA. Times are averages from documented projects. Your operation may vary — use the data as a comparative baseline, not an exact budget.
02 — First visible costMaterial costs
Material cost is the easiest to calculate — and the one that changes most between methods. For the 1.8 m figure (3 units), the breakdown is:
EPS + finish
FGF Printing — Fused Form
The main difference is industrial pellet vs. EPS and its cover materials. Virgin HIPS pellet costs between $3.5 and $5 USD per kg, while covering three EPS figures with resin and hardened fabric adds up quickly. And pellet doesn't require the costly PPE that working with polyester resins demands.
Using recycled pellet? Material cost can drop an additional 35–45% with good-quality recycled pellet. For scenography pieces that will be primed and painted, the final result is indistinguishable from virgin material.
03 — The cost nobody calculatesManufacturing time
Time is the most expensive resource in a scenography workshop — and the one least often counted in budgets. For 3 units of the reference prop, the real times are:
For a theater set with a fixed opening night, every day of fabrication delay is a day less of rehearsal with real scenography. EPS needs 9 to 14 days per piece because carving, assembling parts and applying the cover is a sequential process — it can't be rushed.
FGF printing is mostly unsupervised time: the machine works on its own for 18–22 hours while the operator handles other tasks. Manual work is concentrated in the post-print finish, which takes 4–6 hours per piece.
04 — The most underestimated costLabor cost
Specialized labor in EPS and fiberglass is scarce and expensive. A sculptor experienced in large-format pieces can charge between $15 and $35 USD per hour in Latin America, and more in the USA. The artisanal process requires constant presence of the specialist.
| Item | EPS + finish | Fiberglass | FGF — Fused Form |
|---|---|---|---|
| Hours per unit (1.8 m) | 55–80 hours | 45–70 hours | 12–18 hours |
| Required profile | Specialized EPS sculptor | Laminator technician | Operator with 8h training |
| Supervision needed | Continuous throughout | Continuous (resins) | Only at start and end of print |
| Labor cost (3 units) | $990–2,400 USD | $810–2,100 USD | $216–540 USD |
| Key person dependency | High — sculptor is irreplaceable | High — skilled trade | Low — reproducible process |
The most important argument isn't just the hourly cost — it's dependency on a specific person. If your EPS sculptor is sick, leaves or isn't available for the project, work stops. With FGF, any operator with basic training can supervise printing and handle the finish following the standard process.
- Operator trainable in 8 hours
- Machine runs without continuous supervision
- Documented, reproducible process
- Doesn't depend on unique craft skills
- Operator can do other tasks during printing
- Requires sculptor with years of experience
- 100% supervised process at every stage
- Each piece depends on craftsman's judgment
- Hard to scale without hiring more specialists
- Physically demanding with toxic materials
05 — The question that decides projectsReplication capacity and scale
When an art director requests five identical Corinthian columns for an opera set, traditional methods have a structural problem: exact replication is impossible without a mold — and the mold costs additional time and money.
| Scenario | EPS | Fiberglass | FGF — Fused Form |
|---|---|---|---|
| 1 unique piece | Viable, standard cost | Viable, requires master mold | Viable, prints directly from file |
| 3–5 identical replicas | Manual, each piece varies | Reusable mold, but upfront cost | Identical by design, same file |
| 10+ units in series | Doesn't scale, inconsistent quality | Scales with mold, high upfront investment | Scales directly, no added cost |
| Design modification | Start over from scratch | New complete mold | Edit the file and reprint |
| Reproduce next season | No guarantee of reproduction | With preserved mold (if it exists) | Digital file never expires |
The 3D file is a permanent asset. A company that prints its scenic columns with FGF can reproduce them two years later for a second season, in another city, at the same material cost and without rebuilding anything. With EPS or fiber, that know-how lives in the craftsman's head or in a physical mold that may deteriorate.
06 — The invisible costStorage and workshop space
This is the cost almost no studio calculates correctly: the space consumed by materials and molds. An active scenography workshop may have dozens of square meters occupied by EPS blocks, molds from previous projects, resin drums and cover materials — space that produces nothing until it's used.
If your workshop pays rent per square meter, freeing 20–30 m² of EPS and mold storage has direct economic value. If it's owned space, that area becomes additional productive capacity. Resin materials have expiry dates — EPS doesn't expire but deteriorates and loses quality if stored poorly.
07 — Numbers in actionReal case: opera set, 14 pieces
Documented case
Full set for Italian opera — Mexico City company
14 scenic elements between 60 cm and 1.8 m: four Corinthian columns, three amphorae, a throne, architectural panels and decorative elements. Urgent production with 4 weeks to opening night.
Estimated cost with fiberglass
Real cost with FGF — Fused Form P1000
The four columns — identical — were produced from the same file in three days. The company kept the 3D files and reused the set for a second season with no additional fabrication cost.
08 — The numbers in summaryConclusion
For the reference prop (1.8 m figure × 3 units), the total compared cost is:
| Item | EPS + finish | Fiberglass | FGF — Fused Form |
|---|---|---|---|
| Materials (3 units) | $480–690 | $600–900 | $250–385 |
| Labor (3 units) | $990–2,400 | $810–2,100 | $216–540 |
| Total time | 28–42 days | 21–36 days | 6–12 days |
| Storage required | High | High + molds | Pellet only |
| Exact replication | Not guaranteed | With mold | Perfect by design |
| Total estimated cost | $1,470–3,090 | $1,410–3,000 | $466–925 |
The total savings per 3-piece project range between USD 1,000 and 2,100 depending on the market and local labor costs. For a studio producing 6 such projects per year, that saving can exceed USD 10,000 annually — not counting the value of freed days to take on more work.
The question isn't whether FGF printing is cheaper. The numbers are clear. The question is how many projects you need to pay off the equipment — and for most active studios, the answer is less than one year.
