Digital Fabrication Lab

The lab was established to promote research on issues related to computer-based design and production in architecture and to enable students and teaching staff in the faculty and at the Technion to access new digital production tools. The lab includes a research lab (TCODE) and a service lab. This page displays information related to the service lab. For the research lab site, click here.

Location

The lab’s new premises are on the ground floor of the Amado building, adjacent to the design lab.

Costs

For a list of services and materials in the lab, click on the link below.

Laser cutting

The lab has two machines for laser cutting of surfaces, with a cutting intensity of 100 Watts.

The machines are capable of cutting, marking and engraving in a variety of materials according to a file line in DXF format or according to an image file.

The cutting surface of the machines is 580X880mm and they can process different materials.

For health reasons, it is only permitted to cut materials from a limited list (see list below). Special cutting materials approved for laboratory use, such as poplar and Perspex of varying thickness, can be purchased in the lab.

For more information on the variety of materials, the cost and how to prepare DXF files for cutting, see the following documents:

Instructions for preparing a DXF file for cutting

See attachment: Table of materials and cutting parameters for use with the laser cutting machine

Laser Safety

The lab presents a number of risk factors ranging from physical damage caused by the laser or hazardous materials to damage caused to costly and sensitive property.

The machine will be run by a responsible trained student. Students who have not undergone training are forbidden to run the machine.

As part of the technical safety instructions for using the laser, during the cutting, the authorized operator of the machine and the person who has booked the lab will be only people allowed in the cutting room.

Those present in the room will use proper protective laser-safe spectacles.

Refer to the safety instructions for using the laser machines before cutting.

3D printing

The lab has two 3D printers, one OBJET, and one ZCORP.

Printers differ in resolution, materials, printing method and, therefore, so do the costs.

The printers work with STL files.

Alaris 30 Objet

The printer prints white polymer material. The printer’s tray size is 30 cm in length, 20cm in width and 15cm in height. The printing accuracy is approximately 0.1-0.2 mm.

More information about the printer can be found at the following links:

Printer Specifications

You can print 3D model files stored as an STL file.

The model should be “water tight”. For details on preparing files for printing on the printer, see the following link.

Details about the possibilities for coloring the model, post-processing, can be found at the following link.

In the lab you can print material of the VeroWhitePlus type. Details about the material can be found at the following link.

In order to schedule a printing session, to confirm that the model is printable and to receive a quote, you must schedule the appointment in the diary, at the following address, and send the STL files to the laboratory supervisor. The time needed to print a three-dimensional model can vary greatly, depending on the size of the model and its level of formal complexity, ranging from a few hours for a small and simple model amounting to a few grams, to a full-day tool for a complex model weighing hundreds of grams.

ZPrinter 350 (ZCORP)

The printer prints plaster-like material.

The tray size is 25.4 cm long, 20.3 cm wide and 20.3 cm high, with a resolution of 300X450 DPI.

More details can be found at the following link.

Material on the printing process and the printer can be found at the following link.

You can print 3D model files stored as an STL file. The model should be “water tight”.

In order to schedule a printing session, to confirm that the model is printable and to receive a price quote, you must schedule the appointment in the appointment diary, at the following address, and send the STL files to the laboratory supervisor. The time needed to print a three-dimensional model can vary greatly, depending on the size of the model and its level of formal complexity, ranging from a few hours for a small and simple model weighing a few grams, to a full day for a complex model weighing hundreds of grams. The print price list appears in the diary webpage.

CNC machine

The machine is manufactured by EXITECH. The machine has a 240 cm long and 130 cm wide work surface. The bridge is 50 cm high, and the machine has an automatic tool changer of 8 tools, which is designed to cut and process wood and polymers (soft materials).

The machine is run by ALPHCAM software and accepts files in most known formats. For a full list of formats, follow this link.

For consultation, setting an appointment and receiving a quote, please contact the student in charge of the lab.

3D scanning

The laboratory has an ARTEC EVA scanner. The scanner allows for three-dimensional scanning of objects up to a small car. The scanning accuracy depends on many factors but can reach up to 0.1 mm.

Details about the scanner can be found at the following link.

Scanning in the faculty will be carried out in accordance with the procedure detailed in the following link. In general, the scan will be performed by a trained student. After completing the scan, the model will be uploaded onto a folder on the server. The work on the scanned model will be carried out by the student in the computer lab using the scanner software installed on all the computers. The software enables mesh correction from the scanning and from external models (in favor of 3D printing or milling).

Details about the program and basic learning materials can be found at the lab’s folder on the server, at the following link (works only on the Technion network). General information can be found at the following link.

Consulting regarding designing and producing complex geometry, fixing mesh problems and preparing for three-dimensional printing / milling

The laboratory has knowledge, cumulative experience and software that enable the following:

  1. Constructing complex 3D bodies, rationalizing three-dimensional objects (3D design objects or 3D scanning).
  2. Preparing files for 3D printing and milling in various materials (soft materials, wood and aluminum).
  3. Repairing 3D files (STL files), converting mesh files to NURBS files.
  4. Comparison of files / models (cloud points, mesh, NURBS)
  5. Consulting in computer-based production of any standard.

We provide consulting services on these topics to researchers and students at the Technion and outside the Technion.
