1. A method of forming a capsule comprising:
applying a laser marking to a sheet of material of a pair of sheets of material; and
forming a capsule from portions of the pair of sheets of material using a pair of die rollers or another pair of die rollers; wherein
each die roller of the pair of die rollers or the another pair of die rollers comprises a cavity allowing the capsule to be formed from the portions of the pair of sheets of material and a filler;
the formation of the capsule from the portions of the pair of sheets of material using the pair of die rollers or the another pair of die rollers employs a capsule filling system;
the capsule filling system comprises:
a first capsule filler comprising a first set of dispensers for the first capsule filler and a first heated wedge;
a first roller pair comprising the pair of die rollers for use with the first capsule filler;
a second capsule filler comprising a second heated wedge;
a second roller pair comprising the another pair of die rollers for use with the second capsule filler; wherein
the capsule filling system employs the first capsule filler that can be swapped for the second capsule filler;
the first capsule filler dispenses a volume of filler into capsules having a first capsule size and the second capsule filler dispenses a volume of filler into capsules having a second capsule size, each said first capsule size and said second capsule size being defined by cavities in the pair of die rollers and the another pair of die rollers, respectively; and
a laser marking system configured for marking the sheet of material of the pair of sheets of material prior to the formation of the capsules of different sizes.
