Despite the dynamic development of additive manufacturing technologies, including selective laser sintering (SLS), there is still limited information on the impact of key factors in printing strategy, on the properties of three-dimensional (3D) printed parts. Such factors, such as the orientation of printed layers toward the powder bed or elements target dimensions, seem to be particularly important, from both a mechanical and a structural point of view. Besides, the scientific articles mainly focus on the analysis of one type of loading condition in the samples, that is, the uniaxial tensile test, which were printed on industrial SLS printers. This is a considerable limitation because very often not only tensile forces but also compressive forces act on the structural elements. Therefore, this study aimed at evaluating the influence of desktop SLS printed parts' orientation and diameter on their structural and mechanical parameters. The mechanical properties of samples printed from PA12 powder on the desktop SLS 3D printer were tested in uniaxial tensile and compression tests, as well as structural properties were investigated. For the purposes of this article, 5 angular orientations of the samples in relation to the powder bed and three diameters of cylindrical samples were analyzed. The research has shown that in the case of samples subjected to tensile load, the printing strategy is important, and the best mechanical parameters are obtained for parts printed at an angle of 0, that is, in the powder bed's plane. The highest values of mechanical parameters were obtained for a part oriented at an angle of 0. In the case of the uniaxial compression test and structural parameters, the parts orientation turned out to be an insignificant factor affecting the tested parameters. However, the diameter of printed elements was proven to have a significant influence; the best geometric and dimensional representation was observed for parts biggest in size.
DMA25 is a desktop DMA offering a high force range up to 25N and outstanding flexibility from glass transition determination to immersed tests, which makes it a powerful thermomechanical testing platform.

Accuplacer is a computerized test that evaluates your skills and places you into appropriate level courses. It is an untimed test used to determine students' knowledge in the areas of reading, writing, arithmetic, and quantitative reasoning, algebra, & statistics (QAS). Students take an average of 2 hours to complete.
Most associate degree and technical diploma programs require a skills assessment prior to full admission into the program. Check the Admission Requirements section to see if your program requires a skills assessment.
If you are not able to attend the ACCUPLACER assessment at your scheduled time, you MUST drop the class to receive a refund. If you do not drop the class before the day you are scheduled to test, you are responsible for the fee. You can drop the class through your MyFVTC account or by calling Enrollment Services at least one business day in advance at 920-735-5645.
You will be allowed to re-test only once. All re-test sections must be completed in one session. We recommend 30 days before re-testing to allow yourself time to study. To schedule a re-test, follow the same registration instructions as your initial assessment. Another $15 assessment fee will be charged.
The Test of Essential Academic Skills, Version 6 (ATI TEAS), measures knowledge in the academic content areas of reading, mathematics, science and English and language usage. The TEAS exam is 170 multiple choice questions and is a timed test lasting a total of 3 hours and 29 minutes.
Once your session is scheduled, create an ATI account at www.atitesting.com prior to your test date. You only need a username and password at this point. Please see our TEAS Instructions (PDF) document for more information on creating your ATI account.
You will be allowed to re-test only once. If you do not successfully re-test within 3 terms of your initial TEAS exam, your program application will be withdrawn. After the third term ends, you will need to re-apply if you are successful on the re-test exam.
To schedule a re-test, follow the same registration instructions as your initial assessment. Another $65 assessment fee will be charged. If you are not successful on a re-test you will only be allowed to take the TEAS exam after a 3-year waiting period.
At the completion of your assessment, you will receive your printable score report. Your scores will always be accessible to you on your MyFVTC Account as well as by signing into your ATI account at www.atitesting.com.
In addition to the ACCUPLACER, some FVTC automotive programs also require the Bennett Mechanical Comprehension Test - II (BMCT-II). This assessment is used to determine your aptitude for learning mechanical skills in your applied mechanical job. It measures a complex set of abilities. Your mechanical knowledge, spatial intelligence, and mechanical reasoning are tested and analyzed. The BMCT-II is a 25-minute timed assessment consisting of 55 multiple-choice questions that represent samples, with illustrations, of frequently encountered mechanical situations. This assessment is offered at the Appleton and Oshkosh campuses only. Follow the registration process below.
All materials are provided at the testing session; personal belongings are not allowed in the testing room. Lockers are provided, but a quarter is needed (will get back when finished.) You will be provided instructions for the exam process. You will receive a copy of your score report after you complete the test.
Please allow yourself at least 45 minutes for parking, finding the room, checking in at the Testing Center, completing the test, and getting your scores.
You will be allowed only one re-test. Follow the above registration instructions for your re-test. Another $14 assessment fee will be charged. Please let the proctor know at check-in if it is a re-test.
Fracture testing is a useful mechanical testing process to explore the properties and behavior of materials, one that has seen much development and refinement in recent decades. One of the most important steps in preparing samples for testing is the production of a sharp pre-crack to initiate crack propagation in a predictable way. While several methods have been developed for doing this, particularly for metals and brittle plastic materials, a quick and reliable method for more ductile materials is lacking. This paper describes the design and verification of a simple desktop-sized pre-cracking device which safely uses a razor blade and hammer to quickly produce straight and sharp pre-cracks of consistent depth in ductile polymeric material samples. To verify its capability and consistency, a series of tests was performed using both molded and 3-D printed acrylonitrile butadiene styrene (ABS). First, a series of 40 notched 25mm9.5mm ABS bars was pre-cracked, and the distance under the crack measured on both sides of the bar. Several bars were then broken along the cracks to examine the quality of the pre-crack front. These tests were then repeated 20 times each for two print orientations of fused deposition modeling (FDM) ABS printed at 100% density. All 80 pre-cracks were found to be straight, sharp, and within 1% of the nominal distance under the crack for all samples. The consistency of the pre-cracks throughout the sample cross-section was also observed to be excellent, with all 80 tests showing less than 0.25mm of deviation, even on the highly-anisotropic FDM samples.
