Machines
3D Printer
Any Fusion Deposition Modeling (FDM) 3D printer can be used to manufacture the POP kiosk parts, but we recommend these two printers for makers looking to explore 3D printing for the first time. The CR-10 offers a great experience for beginners, while also allowing customization through custom firmware and printer upgrades. The Ender 3 S1 Pro offers slightly less customizability, but it works out-of-the-box with many more advanced filaments.
| Manufacturer | Part | Description | Avg MSRP Unit Cost | Qty. | Total Cost |
|---|---|---|---|---|---|
| Creality | CR-10 | This is a low-cost beginner 3D printer to can be used to learn the basics and expanded to print with advanced materials, such as ASA, PC or PP. | $309.00 | 1 | $309.00 |
| Creality | Ender-3 S1 Pro | This is an entry level 3D printer that can be used to print flexible and more advanced materials out-of-the-box without printer modifications. | $479.00 | 1 | $479.00 |
Consumables
Filament
There is an expansive range of filament materials and colors that can be used to print the POP kiosk case. Many filaments are based on plastics or plastic composites, each of which have their own material characteristics and environmental concerns.
For prototyping and non-production uses, we recommend using PLA (polylactic acid) because it is low-cost while still offering high print speed and quality. For final production prints, we use PETG for gallery kiosks. We chose PC or PP for cases that are subject to bumps and abrasion through travel and storage. TPU or TPE are used for parts that require flexibility.
| Manufacturer | Part | Material | Description | Avg MSRP Unit Cost | Qty. | Total Cost |
|---|---|---|---|---|---|---|
| Amazon | Basics PLA | PLA (Polylactic Acid) | This is a reasonably-priced, moderate-quality filament that can be used to rapidly prototype and trial kiosk parts. This material is brittle with low impact resistance.
