When developing a product and adding a design change, you may find yourself needing to have molds done before even having a sample made... however... what happens when you first pay for the mold, then receive your sample and the product needs to be slightly changed ????? Now you need a new mold...and this can get very costly!   On Thursdays with Sharon Even, Sharon shares how she recently had a sample 3d printed before the final design was made and sent to the supplier and then had a temporary mold made for the pre-production sampling. This process could save you thousands and is something every product developer should know.
