3D Printing - Manufacturing-Tooling Solution - Molded Fiber
Molded paper pulp, which is also called molded fiber, has been used since the 1930s to make containers, trays and other packages. Molded pulp packaging experienced a decline in the 1970s after the introduction of plastic foam packaging. But more recently the use of molded pulp packaging is growing because it fits in well with today’s emphasis on environmental friendliness and sustainability. Paper pulp can be produced from old newsprint, corrugated boxes and other plant fibers. Today, molded pulp packaging is widely used for electronics, household goods, automotive parts and medical products. It is also used as an edge protector or pallet tray for many shipping and handling applications.
How it works
Molded pulp packaging tools are normally made by machining a metal tool in the shape of a mirror image of the finished package. Holes are drilled through the tool and then a screen is attached to its surface. The vacuum is drawn through the holes while the screen prevents the pulp from clogging the holes. It costs about $30,000 and takes two weeks to make a metal tool for a typical large package.
Fused Deposition Modeling (FDM) provides an alternative method for producing molded pulp tooling that can provide dramatic time and cost savings and improve the appearance of the finished product. FDM technology is an additive manufacturing process that builds plastic parts layer by layer, using data from computer-aided design (CAD) files. FDM molded pulp tooling can be produced in a fraction of the time and cost of conventional tooling because the FDM tool can be produced to be both porous and rigid. FDM eliminates the need for costly machining of the contour of the tool as well as the holes required to draw the vacuum. FDM also eliminates the need to attach the screen to the mold.
FDM molds can be run alongside traditional molds with no alternation to the slurry formula, cycle time, vacuum pressure or other process variables, making it easy to integrate FDM tooling into any molded fiber operation.

The Technology Used for Creating 3D Printed Concept Models
Fused Deposition Modeling (FDM) Technology
Using FDM technology allows affordability and durability by printing concept models with production-grade thermoplastics.
FDM 3D Printers are office friendly and they produce small models in hours and large models in days. The FDM printed models can be drilled, sanded and painted according to your preference to create a perfect finishing of your prototype.
PolyJet 3D Printing Technology
As a 3D printing process, this technology produces amazingly realistic models. The printing technology builds accurate models by incorporating multiple materials into one automated part to create prototypes that look and feel like finished products. With fine details, smooth surfaces, rigid housings, soft-touch buttons, lettering, rubberlike seals and even clear components, your models can look the part at a trade show, a presentation or even during a sales pitch.
