Many papers were focussed on holographic photopolymers
The nature of the recording medium plays a key role in the realization of this promising technology; photopolymers
appear to be the most suitable materials (1-9).
Our flexo customers have long valued the productivity enhancing features of Asahi photopolymers
A new line of photopolymers
for rapid prototyping is said to offer PP-like toughness, strength, and flexibility.
Moreover, says Huntsman, it allows for the production of QuickCast investment casting patterns as well as robust parts from a single vat of material, eliminating the need to switch photopolymers
with each new project.
Roll compounds provided include nitrile compounds, EPDM compounds, fluoroelastomers, millable urethanes, polychloroprenes, natural rubbers, silicones, photopolymers
, thermoplastic elastomers, thermoplastic vulcanizates, antistatic conductive materials and more.
Objet's Eden333 uses UV-cured photopolymers
that come in front-loading cartridges to create models about 13.
Cons: Requires support structures, which can be difficult to remove, post-curing needed, photopolymers
may be toxic and/or hazardous.
This is because thermoset photopolymers
do not melt, they expand before they burn away.
Bayer MaterialScience is supplying color-sensitive photopolymers
that are ideal for the mass replication of the true-color master holograms produced by Ultimate Holographic Reproductions.
In addition, there are handling, preparation and storage problems associated with photopolymers
Platemaking materials include Flint Group's full line of nyloflex[R] photopolymer
plates, plus water-wash Cosmolight[R] and Printight[R] from Toyobo, and liquid photopolymers
