short beam and square column mold

This is a mold for creating short beams and square columns using PLA 3D printing waste (multicolored purging material, failed prints, and end-of-spool filament). The shell needs to be printed with PETG (approximately 300 grams), and fluid plaster should be injected (about 2.5 kg of plaster powder, 900 grams of water).

The forming size of 200 grams of waste is approximately 40*200*20 mm. The forming size of 400 grams of waste is approximately 40*200*40 mm.

Heating tools such as an old oven, panini press, air fryer, etc., can be used. Additionally, you will need a respirator, silicone baking tray, and heat-resistant gloves.

Filament purge are very uniform and easy-to-melt waste materials, taking about 15 minutes to melt 200 grams.

200 grams of "low infill failed prints" take about 30 minutes to melt.

Applying a small amount of Vaseline to the mold will help with demolding.

这是一个使用PLA 3D打印废料（多色冲刷料，打印失败件，末端耗材）制作短梁与方柱的模具。需要使用PETG（约300克）打印外壳，注入流体石膏（约2.5kg石膏粉，900克水）。

200克废料的成型尺寸约为40*200*20mm。400克废料的成型尺寸约为40*200*40mm。

加热工具可以使用废旧的烤箱，帕尼尼机，空气炸锅等。另外需要：防毒面罩，硅胶烤盘，隔热手套。

「多色冲刷料（竹屎）」与「线材」是非常均匀且易于熔化的废料，200克大约需要15分钟熔化。

200克「低填充的失败打印件」大约需要30分钟熔化。

在模具上涂抹少量凡士林将有助于脱模。
