You can make a functional face shield at home using a few basic materials: a clear plastic sheet for the visor, a headband or frame to hold it in place, foam padding for comfort, and an elastic strap to secure it. The whole process takes under an hour with simple tools, and you have several options depending on whether you own a 3D printer or need a no-tools approach.
Materials You Need
The visor is the most important piece. The standard material used in commercial face shields is PETG plastic, a clear thermoplastic that resists impacts and provides good optical clarity. Commercial visors are typically about 0.040 inches thick (roughly 1 millimeter), measure around 8 by 16 inches, and offer both splash protection and impact resistance. You can buy PETG sheets online or at plastics suppliers. Acetate sheets and transparency film (the kind used for overhead projectors) also work for lighter-duty shields, though they scratch more easily.
For the headband, you have three main options: a 3D-printed frame, a craft foam band, or a simple elastic strap system. You’ll also want closed-cell foam for the brow piece (the part that rests against your forehead), a standard hole punch, and rubber bands or elastic cord to hold the visor to the frame.
Option 1: 3D-Printed Headband
If you have access to a 3D printer, this produces the sturdiest and most comfortable result. The National Institutes of Health hosts a clinically reviewed face shield design (the DtM-v3.1) on its 3D Print Exchange that was authorized for production during the COVID-19 pandemic. The headband file is freely downloadable and uses roughly 50 grams of filament per part.
PLA is the recommended filament for printing the headband. Acceptable alternatives include PETG, ABS, ASA, and nylon. PLA is the easiest to print with and widely available, but it can soften in high heat (like a hot car), so PETG is a better choice if the shield will be stored or used in warm environments. Print the headband with standard settings, no supports needed, and expect a print time of about two to three hours depending on your machine.
Once printed, punch holes along the top edge of your PETG visor sheet to align with the pegs on the headband frame. The visor snaps or slots onto the frame. Attach a strip of adhesive-backed foam along the inside of the brow area, and add an elastic strap at the back for a snug fit.
Option 2: No-Printer Foam Band Method
This version requires no special equipment. Cut a strip of thick craft foam about 2 inches wide and long enough to wrap from temple to temple across your forehead (roughly 10 to 12 inches for most adults). The foam serves double duty as both the structural band and the comfort cushion. Closed-cell foam is ideal because it resists sweat absorption and cleans easily.
Attach the PETG or acetate visor to the foam band using a stapler, with staples placed about an inch apart along the top edge. Make sure the staple ends face outward, away from your skin. Punch a hole at each end of the foam band and thread elastic cord or a rubber band through to create the rear strap. Adjust until the shield sits comfortably about an inch away from your face.
That gap between your face and the visor matters. It needs to be large enough to accommodate glasses or a mask underneath, but not so large that the shield shifts around while you move.
Option 3: Elastic and Hole-Punch Method
The simplest possible version uses just a clear plastic sheet and elastic. Cut your visor material to roughly 8 by 16 inches. Punch two holes near the top corners, about half an inch from each edge. Thread a length of elastic (sewing elastic works, or even a cut rubber band) through both holes and tie it at the back of your head. Add a strip of adhesive foam along the top inside edge for forehead comfort.
This method is the fastest to assemble but the least stable. It works well for quick tasks like woodworking or cooking with hot oil, but it tends to shift during prolonged wear.
Preventing Fog Buildup
Fogging is the biggest annoyance with homemade face shields, especially if you’re also wearing a mask. A thin layer of dish soap rubbed onto the inside of the visor and then gently buffed with a soft cloth creates a transparent film that prevents moisture from condensing into droplets. Hand sanitizer works similarly, since the alcohol forms a temporary anti-fog coating as it evaporates. Apply either solution before each use for best results.
Positioning also helps. If the visor tilts slightly forward at the bottom rather than sitting flush against your chin, warm breath escapes downward instead of rising up the inside of the shield.
Cleaning Without Damaging the Visor
PETG and acetate are durable but can cloud if cleaned with the wrong chemicals. Isopropyl alcohol is the top recommendation for disinfecting plastic face shields, and it dries without leaving residue. Pre-moistened disinfectant wipes designed for medical surfaces also work well.
Bleach solutions will disinfect the shield, but a 10% bleach solution can fog the plastic over time with repeated use. If you need to use bleach, rinse the visor with plain water afterward and dry it immediately with a soft cloth. Avoid paper towels, which can leave fine scratches that gradually reduce clarity.
For the foam brow piece, wipe it down with a damp cloth and let it air dry. Closed-cell foam holds up to this treatment for weeks, but plan on replacing the foam strip once it starts to compress and lose its cushion.
What Homemade Shields Can and Cannot Do
Face shields are effective at blocking large droplets, splashes, and debris directed at your face. They protect your eyes, nose, and mouth from direct spray, which is why they’re standard equipment in medical settings, laboratories, and workshops.
They are not sealed devices. The open gaps at the sides and bottom mean small airborne particles (anything under about 5 microns) can drift in and potentially be inhaled. The space between your face and the visor is significantly larger than the gap created by a well-fitted mask, so a shield alone offers limited protection against fine aerosols. For respiratory protection, a face shield works best as an addition to a mask, not a replacement.
Fit and design also affect performance. A visor that wraps slightly around the sides of your face blocks more lateral splash than a flat sheet. If you’re cutting your own visor, adding an extra inch or two of width on each side and gently curving the plastic with a heat gun improves side coverage noticeably.
Homemade shields are not rated for high-velocity impact protection. Commercial face shields sold for industrial use meet ANSI Z87+ standards, which involve testing against projectiles at specific speeds. A DIY shield made from thin acetate or transparency film will not pass these tests. For tasks like grinding metal or using power tools, use a commercially rated shield instead.
