WHY

No new product should skip the prototyping stage before its market roll-out. This stage produces many preliminary products which require a similar geometry and, frequently, also similar mechanical and chemical properties like those of the final product. This part is typically very lengthy, involving repeated processes, even if the added-value is only apparent in the final prototype. But this can change!

HOW

Creating new product prototypes brings together experienced designers and 3D printing specialists. They cooperate on the preparation of calculations and materials, saving priceless time that would otherwise be spent on conventional prototyping.

WHAT

Each prototype is produced and subsequently tested in close cooperation and consultation with the customer, which ensures time and technology optimizations of the final product.


Example: Casting mould of rocker arm model

Introduction

One of our industrial partners was looking to optimize the centre of gravity for one of its parts. His was asking for injection technology and a predetermined distribution of mass around the central axis.

Solution of the problem

The mould geometry was designed based on the technology intended for the production of the part in bigger batches. The prototype of the new mould was 3D-printed within several hours. After testing repeatability, and following further optimization and another mould print, the mould was ready for serial production.

Merits

The 3D-printed mould considerably reduced the time delay between the mould design and its serial production. This relieved the supply chain and increased our industrial partner’s competitiveness in terms of timely delivery of new parts.

Direct Light Processing (DLP)

The technology uses selective hardening of a part of a photopolymer bath, using a UV radiation source located below an LCD display which shields the exposed layer to create a desired shape. The hardening process goes layer-by-layer. This printing method is used for very detailed designs, with a very high surface quality and dimensional precision which is higher than that of FDM technologies. More >>

Fused Deposition Modelling (FDM)

The printing process is based on the deposition of individual layers of molten thermoplastic that are supplied to the print head in the form a filament or granulate. After its application, the molten material cools down and solidifies. The resulting quality of the product relies on printer design quality and on how well the printing parameters are tuned to the thermoplastic and the printing machine used. More >>
