3D printer prints layer on layer, which means every layer is printed on an existing one. Therefore, printing models with overhangs that are supported by nothing below are prone to failure. In such cases, we could add support structures when slicing the 3D models to ensure successful prints. Since the support structure does not belong to the model, you also need to remove it after the printing.
You can manually remove the support structure with the following tools, slowly and cautiously.
Provided. Usually more used to remove the outer support structures than the inner and deeper ones.
Not provided. A Handy tool to remove the support deep inside the print, but not suitable for handling the intricate parts.
Not provided. Its sharp blade makes it possible to cut and remove complex and tangled support structures.
Be careful with precision knives. We recommend wearing gloves before the operation.
Once you've experienced the struggle of manually removing complex support structures, you will appreciate the advent of PVA, a kind of water-soluble filament particular to print support structures.
To remove the support structure printed with PVA:
Using higher-temperature water or timely renewing the water can help accelerate the dissolving process.
The waste water containing PVA solutions entails special treatment. For complete guidance, refer to the information provided by the PVA filament manufacturer or consult the responsible local authority.
