Are you looking at a complicated print job that involves supporting overhanging parts or intricate designs?
Maybe you want to try a material that’s similar to PLA and just as easy to work with, but will also provide the aforementioned support?
If that’s the case, then rigid.ink PVA is the material for you.
PVA, or polyvinyl alcohol, is a synthetic polymer that is strong, non-toxic, biodegradable and, for support purposes, water soluble. That fact that PVA will dissolve in water has led to its being used commercially in a number of products from laundry packs to eye drops. When it comes to 3D printing, the water solubility of PVA makes it an excellent tool to use to provide support to objects that include overhangs or detailing.
As you already know, 3D printing proceeds from the bottom up. If you’re printing an object that incorporates overhangs, areas of your design that doesn’t have any underlying material, you’re going to have trouble. Printer filament has to extrude onto some type of surface, either a build plate or a previously extruded layer of material.
rigid.ink PVA gets rid of the problem by providing a support surface for these overhangs. First, your printer extrudes a layer of rigid.ink PVA underneath the area where the overhang will be. Once the PVA is in place, your printer will have a surface that it can use to lay down the overhanging portions of your object. rigid.ink PVA prevents the distortion or collapse that would happen without the necessary support.
Once you print job is done, removing rigid.ink PVA filament is extremely simple. There are no chemicals involved and you won’t need knives or other tools to remove the support material you no longer need. All you need to do is submerge your object in a container of room temperature water for several hours. The water will completely dissolve the rigid.ink PVA. You’re left with an object that has sharp clean lines and a remarkable level of detail.
When using a support material, it’s very important to be aware of the print temperature of your printing material and your support material. If there is a significant variance between the two temperatures, you may find that one material will warp and deform the other material during the printing process. That’s why PVA works so well as a support material when PLA is being used as the print material. You see, PVA and PLA have very similar printing temperatures. This results in the two materials laying cleanly together without any warping or deforming.
When you’re printing with rigid.ink PVA keep your fan speed lower, high fan speeds can blow newly extruded PVA off alignment before to gets a chance to set. Keep your printing temperatures between 190°C and 210°C, depending on your particular extruder. Use a print bed temperature between 50°C to 60°C and keep your print speed a tad lower than normal, around 30mm/sec.
It’s also important to remember that rigid.ink PVA is not only water soluble, it is also highly hygroscopic. This means that it will absorb moisture directly from the air. The more humid the air, the more water the material will absorb. This means that you should store your rigid.ink PVA in an airtight cool, dry place in order to maintain its strength and integrity.
