Welcome to the Innevation Center PMT! If you are new to using the PMT, this is your ultimate guide to getting started with us. What is a maker? Everyone is a maker in some way, shape or form. Makers are people who want to create something – from innovators, to small business owners, DIYers, artists, hobbyists and everyone in between. The PMT is a place for you to bring your ideas to life. The PMT has an assortment of equipment that you can use for your creations and staff who will guide you. PMT equipment and training Safety badges The PMT uses safety badges to keep track of the equipment you’ve been trained on and to the extent you’ve been trained on each piece. These badges are given after the completion of the general safety quiz. Safety badges also serve as a reminder for safe use of the equipment based on three different colored stickers: yellow, orange and red. Yellow level The yellow sticker indicates that you are being trained on a certain piece of equipment and may need some help with the equipment. In order to move up from yellow, you’ll need to demonstrate knowledge of the use of the equipment. Orange level The orange sticker indicates that you have been trained on a piece of equipment, but others need to be in the space with you while using it. For certain equipment, orange is the maximum level due to safety hazards for solo use of that equipment. All equipment in the machine shop, excluding the laser cutter, are limited to the orange sticker. Red level The red sticker indicates that you have been permitted to use a piece of equipment by yourself in the PMT, with or without other people in the space. PMT staff safety badges Everyone has a safety badge, including the PMT staff. Staff safety badges are bright pink and will have purple stickers instead of yellow, orange or red stickers. The purple stickers indicate that the staff member has been trained on the safe use of a piece of equipment and is able to help you with it. PMT staff In the PMT you’ll find the wonderful PMT student staff wearing bright pink safety badges who are eager to help you out on all your Maker needs! The staff are trained on all of the equipment and will help you get started on your project. The goal of the PMT staff during training is to help you get comfortable with the equipment. Feel free to ask the staff any questions you may have or let them know if you need assistance. 3D printing 3D printing is open to everyone in the community. In order to start a print with us, you’ll need to have an STL file and an idea of the material you’d like to use for your model. The PMT has a wide variety of material that you can use, from PLA, ABS, ASA, TPU, Standard Resin, Tough Resin, Flexible Resin, and Elastic Resin. You can either email the file to the PMT at PMT@unr.edu or come in with your model and talk to the staff about your print. The PMT staff will help you figure out what option is best for your model. After slicing your print, the PMT staff will provide an invoice and, with your permission, move forward with printing. The invoice includes the cost of material, time on the printer and post processing. Once the print is finished, you’ll receive an email that it’s ready for pickup. Beta space, laser cutter and podcasting training The beta space includes the vinyl cutter, textile lab and electronics lab. In order to use the equipment in the beta space, you’ll need to complete the general safety quiz for the PMT. After the quiz, you’ll receive a safety badge and the PMT staff will help you get started on a piece of equipment and teach you how to use it if needed. Some equipment, like the vinyl cutter, have their own manual that you can read through for more assistance. The high-powered laser cutter can be found in the machine shop. Just like the equipment in the beta space, you’ll complete the general safety quiz, get your safety badge, and receive training on the laser cutter. The high-powered laser cutter can engrave and cut through a wide variety of material such as acrylic, wood, leather, plastics, fabric, MDF, cardboard, paper, Corian, foam, fiberglass and rubber. It is also used to engrave acrylic, wood, leather, plastics, fabric, rubber, cork, brick, phenolic, melamine, glass, granite, marble and tile. The podcasting studio is a separate room near the back of the PMT. In order to use the podcasting studio, please book an appointment with the front desk. After booking an appointment the PMT staff will help with any questions you have. Machine shop training The machine shop includes equipment such as the high-powered laser cutter, horizontal and vertical bandsaws, belt sander, drill press, CNC mill and lathe, manual mill and lathe, and a wide variety of power tools. With the exception of the high-powered laser cutter, you must complete a safety quiz targeted toward machine shop safety. After completing the safety quiz, you’ll receive training on all the equipment. The PMT has a variety of personal protective equipment (PPE) available, from safety glasses, noise canceling ear muffs, hair ties, and more, to help make sure you’re safe when working with the equipment. Each piece of equipment has a manual and a safety sheet for additional assistance on the equipment and correct safety procedures. Things to do and know before your first visit Before you come down to the PMT, there are a few things you should know and do. Booking an appointment The PMT is available through appointment or walk-in. Appointments must be requested 24 hours in advance through our booking portal or by calling the PMT at (775) 682-8613. Book an appointment for a piece of equipment. Dress code There are two important dress code requirements for the PMT. Everyone using the machine shop must wear closed toed shoes. It’s important that you not wear loose fitting clothing when using the equipment in the machine shop and a few other items in the PMT, such as the sewing machine. Costs Depending on what you are planning to do, there are some costs you should be aware of. Using the machine shop, podcasting studio, beta space or the computers Public: There is an $18 PMT day pass that will give you access to all of the equipment for the day during our business hours. If you are looking to come in more frequently over a period of time, there is a multi-day pass that can be purchased for $250. University students, staff and faculty: Free Members: Included in your membership package 3D printing You don’t need to buy a day pass. The PMT charges fees based on material used, time on the equipment, cost of labor and an intake fee. Rates differ for University students, staff or faculty, members of the Innevation Center and community members. Hours of operation The PMT is open during the same business hours as the Innevation Center: Monday - Friday from 8 a.m.-5 p.m., and Saturday from 12-5 p.m. Basic PMT safety You’ll be asked to review our basic PMT safety training and you’ll need to pass a quiz covering the information. If you plan on using the PMT just once, following the quiz you’ll receive a temporary safety badge. If you plan on continuing to use the PMT, we’ll give you a permanent safety badge with your name and safety training date.
3D Printer Automated Bed Swapping System Loads From A Magazine
FDM 3D printing has gone beyond prototyping and is being used as a production tool by many companies. However, conventional printers still require an operation to pop the finished part of the bed and start a new print. [Thomas Sandladerer] wanted a way to swap beds without human intervention, so he built an automatic print surface changing system. The most obvious solution to this problem may appear to be belt printers like the Creality CR-30, but these come with some trade-offs. Bed adhesion can be a problem, and the lack of a rigid print surface causes some parts to come out warped. [Thomas] wanted to be able to use PEI-coated steel beds to avoid these issues. His solution is a system that pulls beds from a “magazine” and pushed out the old bed after a part is finished. It still uses a magnetic heatbed, which lowers out of the way before changing print surfaces. Each print surface is fitted inside a 3D printed frame which rests on the tool changer frame and keeps it in place as the heatbed drops down. The bed frames are printed using ASA, can handle 90 C without problems. The pusher mechanism and the heatbed lowering system are driven by stepper motors which connect to the spare motor outputs on the printer’s control board. The printer in question is a Voron 2.4, which is perfect for this application thanks to its high print speed. This tool-changing system is only the first prototype, but it still worked very well. [Thomas] plans to make key improvements like a larger print bed and reduced height. This system might be a good fit for small and large print farms. We’ve seen another bed-clearing system that doesn’t require extra build surfaces, but instead scrapes off the completed part.
