PVA support material is used for 3D printing objects with complex geometries, cavities, or overhangs. PVA supports a model’s shape while it is 3D printed, then dissolves away in water. But as its chemistry makes it sensitive to moisture, its quality can reduce over time in storage. We loo...
For 3D printing with PVA to be most successful, the filament must be stored in a cool place, away from natural or artificial light, dust and moisture. Both HIPS and PVA have limited resistance to UV light. Proper storage is therefore essential to avoid printing problems in advance. For exam...
There is however several drawbacks, such as the inability to adhere to mirror-like heated bed. In order to make the adherence possible, it is advised to use PVA based glue on the surface prior to starting your 3D printing process.
I tried to print it without supports, then with minimal supports, then full supports but no tower, and I finally got it to print with Ultimaker's default supports + adhesion* + prime tower + 3DLAC. * Whenever I use adhesion + support PVA, I set the brim extruder to use the PVA so...
Hi, I am currently experimentally trying to find optimal settings to print TPU with PVA for the model shown below. What my main problem is that whenever I remove the PVA from the structure after it is done printing, the TPU has very poor quality (i.e rou
