Bachelor Thesis Confirms Financial Viability Of 3D Belt Printers Compared To Cartesian 3D Printers

(MENAFN- EIN Presswire)

The One Pro 3D belt printer combines the advantages of additive manufacturing and series production

Cartesian printing vs. belt printing: a ring, a motor angle, an insole, a display housing and a cable duct were compared

The print bed, which is unlimited in length, is suitable for orthopedic shoe insoles in any shoe size. The angled print head saves material and ensures a particularly comfortable surface.

Acquisition particularly profitable for small scale-production, SMEs and entrepreneurs

DüSSELDORF, NORDRHEIN-WESTFALEN, DEUTSCHLAND, February 8, 2023 / / -- Compared to Cartesian 3D printer models, a 3D belt printer already pays off for the small-scale production of a few thousand parts, which is particularly relevant for SMEs and individual entrepreneurs. That is the result of a bachelor thesis commissioned and supervised by the German start-up, ifactory3d .

The bachelor's thesis 'Economic viability and applicability of 3D belt printers for serial production in manufacturing companies' , which was submitted to the Industrial Engineering and Management WIM degree programme at Düsseldorf University of Applied Sciences in August 2022, analyses the economic viability and profitability of 3D belt printers compared to typical Cartesian 3D printers.

Based on five sample objects to be implemented (a ring, a motor angle, a housing, an insole and a cable duct), an economic efficiency calculation was carried out to determine the machine hour rate. It was found that the variable costs for the 3D belt printer (iFactory3D one pro ) were lower in each case than for the regular 3D printer (Ultimaker S3 / S5). Using the 3D belt printer, all five parts could be produced at a lower unit price. That's because, due to the 45° printing angle, less material is required for 3D belt printing, and complex geometries can be printed without support structures. Another advantage of the 3D belt printer is the unrestricted length of the installation space. Where two Cartesian models had to be used to print the parts, the 3D belt printer was able to handle all selected component dimensions and produce parts in one piece, non-stop. This eliminates additional staff costs and waiting times, because the 3D belt printer can run for weeks and produce continuously.

Example cable duct: 3D belt printer reduces printing time, unit price and staff costs
For a long part like the cable duct, the high savings per part are due to the fact that with the One Pro - in contrast to the S3 or even the larger S5 from Ultimaker - the required 1.50 m could be printed continuously in one piece. Using a conveyor belt instead of a rigid and thus limited print bed means that there is no limit to the dimensions in the z-axis. For the assembly space of the S3, on the other hand, the cable duct was divided into a total of eight pieces that had to be printed in two print runs, as only four at a time can fit in the print area. Result: the printing time for the S3 is 66% longer. The required restart of the printing process adds working hours to the production costs. Overall, the unit price for the long part printed on the S3 is approx. 3.5 times higher than for the One Pro 3D belt printer.

When producing larger quantities of small printed parts, such as a ring (spacer) or motor angle, on a Cartesian printer, the objects have to be removed manually from the build plate after 50 or 30 printed parts, respectively, when the construction panel is at maximum capacity. This step is eliminated with the continuously running 3D belt printer, which in turn saves staff costs. Due to the savings in variable costs, in any comparison, the One Pro always reaches a point where the total production costs with it are cheaper. With the Ultimaker S3, the total fixed costs are around 9% lower, which matches the small price difference in acquisition costs. However, thanks to lower operating costs - both for staff and electricity - and lower material consumption, the use of the belt printer always pays off sooner or later, depending on the part.

Artur Steffen, CEO of iFactory3D, said: 'Due to the automation associated with it, a 3D belt printer can significantly reduce manufacturing costs and compete with injection moulding technology. So, for SMEs and individual entrepreneurs, using 3D printing technology in batch production is worthwhile. iFactory3D brings automated serial production to additive manufacturing.'
