3d printing service: speed, efficiency and precision

Share this post

Our 3d printing service is aimed at the production of solutions designed on the specific needs of the customer and is always linked to the development and / or restyling of a new product. Our business and experience is closely linked to the dynamics and needs of the industry, having been suppliers of rapid prototyping services in B2B market for over 20 years. In all industrial sectors, the process of developing new products follows clearly defined steps.

How our 3d printing service works

3D printing service

Coesum has been on the market for over 20 years as a company specialized in the development of new products and has all the professional production technologies at home of prototypes and small series in plastic and metal.

There are some phases preceding the realization of the prototype which are fundamental for choosing the most suitable process, the steps are

  1. 3D file analysis
  2. Collection of technical specifications
  3. Rapid prototyping technology choice

3D file analysis

The fundamental requirement to start any preliminary evaluation is to have a three-dimensional file of the prototype to be made which must be designed for 3D printing and optimized for the specific process chosen. The design phases end with the creation of an .stl file.

Collection of technical specifications

In this first phase, we believe it is essential to collect the project specifications to understand the functionality of the prototypes that the customer must make. This is because only by carefully choosing the 3D printing service and the materials, will you be sure to be able to get answers from the prototypes made, to be able to use them for the functionality that we initially assumed. This step is essential above all the first time we use a 3d printing service so we don’t know the difference between the rapid prototyping processes and the materials.

The questions we always ask are, what are prototypes for? In what area should they be used? Do they have to be subjected to particular mechanical, thermal or functional stresses? Must they be aesthetic prototypes? This is the main information needed to go to the next step

Rapid prototyping technology choice

This step is much faster when the customer already knows all 3D printing technologies and services, has a 3D file already suitable for the chosen prototyping process and already knows what to buy. In a case like this, our online quotation service can be useful for a preliminary assessment. Once the process has been chosen, it is possible to define the cost for the production of the prototype and the relative time required for production. Generally the prototyping processes are very fast and within a few days 2 or 3 on average you can deliver. What may affect the time of realization of the pieces are any surface finishes and obviously the size and number of prototypes to be made. Costs and production times are defined before starting each 3D printing process.

What technologies can you use

Rapid prototyping was born and evolved quickly thanks to the use of plastic materials. Historically the use of these technologies has allowed design freedoms and applications such that the success and the increase over the years still has no limits

Typical professional technologies most used in the industrial sector are

  1. Stereolithography (SLA)
  2. Selective laser sintering for nylon (SLS) and metal (DMLS)
  3. HP – Multijet Fusion
  4. Fdm Fused Deposition Modelling

In addition to 3D printing, there are other technologies that are usually used for the production of prototypes and small series, in particular the mechanical milling processes. This process allows you to create prototypes with definitive plastic or metallic material, and better precision than 3D printing in the face of higher costs and lead times. As an alternative to 3D printing, where preliminary conditions allow, it is possible to produce small series in materials that simulate ABS with replicas from the silicone mold. This process is generally valid when there is a need to produce a pre-series (dozens of prototypes) with plastic materials and better performance than what I can achieve with 3D printing services. In this area I have the possibility to use rigid, semi-rigid materials and rubbers also with V0, Food, Medical etc. certifications.

What materials can you use

The choice of materials is also an added value for the customer because it has a direct impact on the creation of the prototypes. Our attention to this issue is maximum as well as the care and updating constant and continuous that we ask our suppliers as well as research constant new suppliers. Beyond this, our commitment is also reserved for collaborations with research centers and universities for the study of new ones resins that can be used in stereolithography.
