Note sull'episodio

Resin printers build objects upside down, out of a puddle of liquid, hardened one hair-thin slice at a time by violet light. The result is detail that filament printers simply cannot match: raised text a millimetre tall, tabletop miniatures with individual fingernails, jewellery masters ready for casting. But the process comes with a chemistry set attached: washing, curing, gloves, ventilation and waste you cannot pour down the sink. This episode walks through how it all works and when it is the right tool.

You'll come away understanding how photopolymerisation and 405 nanometre light turn liquid resin solid; the difference between SLA laser, DLP projector and MSLA/LCD printers; why layers are 0.025 to 0.05 mm and why print time depends on height rather than how many parts you load; what peel forces, supports, hollowing and orientation have to do with a successful print; the wash-and-cure chain with isopropyl alcohol and UV light; the main resin families, from standard and ABS-like to flexible, water-washable and dental or castable; the real safety story around skin sensitisation, fumes and disposal; and honest numbers on build volumes, printer prices and resin costs in Australian dollars.

For anyone weighing up a first resin printer, painters and gamers curious about printed miniatures, and makers deciding whether a job belongs on the resin or the filament machine.
