- | Don't break anything, please. | + | In order to use the vacuum former, members must be signed off by an area champion after completing training. If you would like to schedule a training session, please |
+ | |||
+ | |||
+ | Training Classes: | ||
+ | * Occasional open trainings which add a 2' | ||
+ | * Trainings by request with hands-on 5" demo | ||
+ | * Typically take <30 minutes | ||
+ | * No longer any cost associated with the training | ||
+ | |||
+ | Safety Guidelines: | ||
+ | * Do not leave either unit unattended while heater is on… EVER | ||
+ | * Smoke indicates overheating, | ||
+ | * Plastic is hot when heated, do not touch without protection and due care | ||
+ | * Do not allow dust or debris which could contaminate the tanks onto the large bed | ||
+ | * Consult an area champion before using materials not on official list | ||
+ | * Turn off both the “Master heat” and “Side Outlet” switches when done | ||
+ | * Do not use buck materials which may suffer under heat or cause debris ingestion | ||

+ | ===== Buck Guidelines ===== | ||
+ | |||
+ | * A “Buck” is the term for the item you mold off of, but mold is fine | ||
+ | * A 5 degree “draft” to avoid verticals helps keep corners clean | ||
+ | * Extreme height difference between points of the buck could cause tearing | ||
+ | * Sharp corners are typically fine, but actual edges are likely to pierce the plastic | ||
+ | * “Undercuts” will usually form ok, but as a natural consequence prevent normal removal | ||
+ | * A generally convex shape for the entire buck is a good standard | ||
+ | * Shallow areas which do not access outside edge should have holes drilled to funnel air | ||
+ | |||
+ | ===== APPROVED BUCK MATERIALS | ||
- | The heating elements on the vacuum former reach >150° Centigrade | + | * Wood of all forms, with MDF being a preferred material |
+ | * Hard plaster or ceramics are common for making molds | ||
+ | * Existing products and hard plastic models can be great for bucks | ||
+ | * Metals work great if you have something | ||
+ | * Renshape, urethane modeling blocks, and molded epoxy are designed for buck use | ||
+ | * 3D printed ABS is preferred for 3D printed bucks | ||
+ | * 3D printed PETG for most commonly formed plastics | ||
+ | * PLA can work but may deform. | ||
+ | * NOT soft plastics or Sculpy (they melt) | ||
+ | * NOT wet clay/ | ||
+ | * NOT foams (they squish) | ||
+ | * NOT anything crumbly or dusty (they make a mess inside | ||
+ | * NOT wet clay (both squishes and makes a mess) | ||
+ | * NOT potatoes (mostly just a waste of food, otherwise | ||
+ | * If you want to use other materials, send the area champions | ||
- | ===== FAQs ===== | + | ===== APPROVED VACUUM FORMING PLASTICS |
+ | * .030” thickness is minimum recommended merely due to difficulty of use | ||
+ | * .040” or 1mm is preferred thickness for most projects | ||
+ | * .080” or 3mm is the maximum we expect these machines to mold | ||
+ | * High Impact Polystyrene (preferred) | ||
+ | * Abs | ||
+ | * Pvc | ||
+ | * Acrylic | ||
+ | * Polyethylene | ||
+ | * Polypropylene | ||
