PLA
PLA (PolyLactic Acid) is the most common kind of plastic used in 3D printing. It is easy to use, safe to humans, and completely reusable. Parts made in this material can be recycled into new parts with zero quality loss.
PETG
PETG (Polyethylene terephthalate glycol), a glycol modified version of the common PET plastics used in water bottles, can also be recycled unlimited amount of times from old parts. This material has more of a squish/give to it, making it suitable for parts which might be subject to sudden impacts.
Materials with fillers
Materials with fillers (Stone, iron, stainless steel, etc…) can have changes on the item, such as weight increase, layer adhesion weaknesses (Lines along the vertical of the part), and a different texture.
A note about stainless steel & iron fill
These materials come with a California P65 warning on them. We are unsure of if they apply to finished products or not, but we are adding it here anyways to be on the safe side. You can read more about the cancer warning here.
Engraved/cut objects
Items made with a laser engraver can potentially have unwanted particles released from the object itself as part of the engraving process. This can appear as a slight burnt affect around the item’s corners where it was cut. These are only cosmetic and don’t affect the item in any way.
Cups & other food related items
It is advised to wash any items that are going to come into contact with food before use. Cutting boards and wooden utensils are sealed with a food grade sealer and should be hand washed only. A new coating of an equivalent sealer should be applied after a certain number of uses to keep the wood from drying out.
